How To Avoid Being Hungry

Dr. Ludwig gave a lecture about how to avoid being hungry at a conference in Las Vegas. The actual topic was “Always Hungry?” I attended the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas where this lecture was given. Dr. Ludwig is a Harvard-based endocrinologist who has been researching weight loss methods and obesity for over 20 years. Here is a list of his major publications.

Dr. Ludwig stated that the low fat/high carb diet popular in the1980’s until the early 2000’s was misguided and probably even harmful. The theory at that time was that obesity was caused by too much saturated fat. This has since been proven to be wrong. Instead it has been proven that increased sugar intake is responsible for the obesity wave.

General information about weight gain

The carbohydrate-insulin model states that without insulin you cannot gain weight, because in order to store fat in fatty tissue you need insulin to transport fatty acids across the cell membrane of fat cells.

In this context it is important to note that high glycemic index food increases the blood sugar. This leads to stimulated insulin production, and the liver converts the extra sugar into fatty acids that get deposited as fat in fatty tissue.

The glycemic load from a person’s diet is the single best predictor for a rising blood sugar level. After food intake the blood sugar goes up, glucagon goes up, epinephrine goes up within 4 hours. It is the epinephrine, which after 4 hours makes you hungry again.

The nucleus accumbens is the addiction center. At 4 hours after a high glycemic index milk shake the nucleus accumbens was stimulated in 12 subjects of a double blind trial.

The nucleus accumbens does not work in isolation. It is not only involved in food satisfaction, but also in sexual satisfaction and even plays a role in satisfaction that some people get from playing video games.

Low-carbohydrate, Mediterranean or low-fat diet

In an Israeli study from the New England Journal of Medicine in 2008 investigators were interested to find out which diet was helping people to lose most weight.

322 moderately obese subjects that were aged 52 years on average were randomized to one of the following diet groups.

They compared

  1. a low fat diet (Atkins type, restricted calorie) with a
  2. Mediterranean diet (low carb, restricted-calorie) and a
  3. Low fat/high carb diet (low fat, non-restricted-calorie)

What was the result? The mean weight losses were: 2.9 kg (low fat group), 4.4 kg (Mediterranean diet group), and 4.7 kg (low fat/high carb group). Of the 272 participants who had completed the intervention after two years of the study the weight loss was 3.3 kg, 4.6 kg, and 5.5 kg in the same sequence as above.

Next the researchers examined the ratio of total cholesterol to high-density lipoprotein cholesterol, which is a measure for the heart attack risk. It was 20% lower from the baseline in group 2 (Mediterranean diet group). The low fat groups (group 1 and 3) were 12% lower from the baseline.

36 subjects had diabetes. There was a clear winner with respect to lower fasting blood sugar and insulin levels, namely the Mediterranean diet (group 2).

The authors concluded that the Mediterranean diet is preferable to low fat diets as they have shown an improvement in lipid profiles and in control of diabetes.

The “POUNDS LOST” study

This was a 2-year study that investigated 4 different lower calorie diets to help people lose weight. Despite the significant difference in diet composition, these 811 free-living overweight or obese adults ages 30-70 from Boston, MA and Baton Rouge, LA lost 16 pounds at 6 months and 9 pounds at the end of two years. The diets were 1) low fat (20%) or 2) high fat (40%) 3) average protein (15%) or 4) high protein (25% of total calories).

The authors concluded that any reduced, calorie-controlled diet would help obese or overweight people to achieve weight loss that lasts. It is interesting that it did not matter whether the diet was low or high in fat, or had low or high protein content. What did matter was that all diets were low in sugar.

Sugar is the driving force

Dr. Ludwig pointed out that without insulin you couldn’t gain weight. High glycemic index food increases blood sugar. The glycemic load is the single best predictor to indicate whether a person will gain weight or lose weight when you consume food. It is an irony that in the 1980’s and 1990’s the wrong assumption that a low fat/high carb diet would be heart healthy created the obesity wave. We have abundant data available that show otherwise: high sugar content of food brings the calorie count up as everybody can read on the food labels.

Sugar stimulates the food addiction center

This will lead to weight increase, which has been abundantly proven. Sugar also stimulates your nucleus accumbens, the food addiction center. As you probably know it is extremely difficult to get out of this food addiction cycle unless you cut out sugar. You even need to go one step further and include many starchy foods that will within 30 minutes of digesting them turn into sugar. Your system makes no difference whether you eat a few teaspoons of sugar or two slices of white bread. The response of your pancreas is insulin, which gladly stores the fatty substances your liver made as fat.

How to get out of the vicious food cycle

As the quoted publications and many other ones have shown, it only matters that you limit your refined carb intake. You can vary the fat content and you can vary the protein content and still lose weight provided you watch the low carb intake. You also need portion control, which is a given! Study glycemic index and glycemic load sites on the Internet. The links I provided are just some examples. The more you educate yourself about carbs, the better for you. Note that many fruit and vegetables belong to the low-glycemic load/index foods. Avoid the high glycemic index foods like dates and cornflakes. Stick to low-glycemic index foods, which are less than 55. With regard to low-glycemic load food the values should be below 10.

The Mediterranean diet is a very desirable diet, which has been proven to be anti-inflammatory.

The zone diet of Barry Sears is also an anti-inflammatory diet and he summarizes this in this link.

How To Avoid Being Hungry

How To Avoid Being Hungry

Conclusion

I have summarized the content of a talk given by Dr. Ludwig. We learnt from this that sugar and refined carbs are the driving force that leads to “feeling hungry”. This stimulates your nucleus accumbens, the food addiction center. Let’s assume that a person is obese or overweight and wants to lose some weight. You need to start by being strict with yourself. Cut out sugar and high-glycemic foods. This will remove the food addiction factor that keeps you going back to the wrong, high calorie foods. You will also consume more low calorie vegetables and fruit, which have more fiber that fills you up.

Monitor your body mass index

Once you are used to the new way of eating, there is no need to count calories. I recommend that you weigh yourself daily on body composition scales and record the results. This allows you to monitor your body mass index (BMI), your weight, your fat percentage, and your muscle percentage. Typically you will lose 2 to 3 pounds per week on such a low-calorie diet. Later the weight loss will slow down to 1 to 2 weeks per week until you reach your goal. Don’t go lower than a BMI of 21.0 to 22.0 and discuss your goal with your doctor.

Magnesium Is Essential To Life

Magnesium is an important co-factor in many biochemical reactions, so magnesium is essential to life.

Many diverse diseases and cancers can develop from magnesium deficiency. The key is to supplement with magnesium regularly to get more than the government recommended daily allowance (RDA). The RDA for magnesium is 420 mg a day for males and 320 mg a day for females.

In the following I will review the diseases that occur without enough magnesium on board.

A lack of magnesium can cause heart disease

In this 2014 study 7216 men and women aged 55-80 with at high risk for heart attacks were followed for 4.8 years. The risk of death from a heart attack was found to be 34% lower in the high tertile magnesium group when compared to the lower magnesium tertile group.

The protective mechanism of magnesium was found to be as follows. Magnesium counteracts calcium and stabilizes heart rhythms. Magnesium helps to maintain regular heart beats and prevents irregular heart beats (arrhythmias). It also prevents the accumulation of calcium in the coronary artery walls. This in turn is known to lower the risk of heart attacks and strokes.

Another study, which was part of the Framingham Heart Study, examined calcification of the heart vessels and the aorta as a function of magnesium intake.

There were 2,695 participants in this study. For each increase of 50 mg of magnesium per day there was a 22% decrease in calcification of the coronary arteries. For the same increase of magnesium the calcification of the body’s main artery, the aorta, fell by 12%. Those with the highest magnesium intake were 58% less likely to have calcifications in their coronary arteries. At the same time they were 34% less likely to have calcifications of the aorta.

In a Korean study a group with low magnesium levels was at a 2.1-fold higher risk of developing coronary artery calcifications compared to a group with normal magnesium levels.

Low magnesium increases your stroke risk

In a 2015 study 4443 subjects, men and women aged 40-75 were followed along.

928 stroke cases developed. The researchers compared the group with the highest 30% of magnesium intake with the lowest 10% of magnesium intake. They had significantly lower blood pressure (7 mm mercury) and lower total cholesterol levels. They also had 41% less strokes than those with low magnesium intake.

In a 2015 study that lasted 24 years the authors investigated 43,000 men.

Those with the highest magnesium supplement had a 26% lower stroke risk. Those with the lowest magnesium intake served as a control.

Among women low magnesium levels were shown to cause 34% more ischemic strokes than in controls.

This study included 32,826 participants in the Nurses’ Health Study. Examiners followed them for 11 years.

It is clear from all these studies that supplementation with magnesium can prevent strokes.

Magnesium protects kidney function

This study examined 13,000 adults for 20 years to see how kidney function was dependent on magnesium levels. Those with the lowest magnesium levels had a 58% higher risk of developing chronic kidney disease. It makes sense when you consider that magnesium is necessary to keep arteries healthy, blood pressure low, and blood sugars stable. When diabetics do not control their blood sugars optimally their kidneys develop kidney disease. The term for this is diabetic nephropathy. In the presence of magnesium supplementation and a low sugar diet people are less likely to develop diabetes or kidney disease.

Magnesium helps blood sugar control

A metaanalysis showed that magnesium supplementation was able to improve blood sugar control. This occurred in both diabetics and borderline non-diabetics within 4 months of supplementing with magnesium.

An important factor in helping control blood sugar is magnesium. Here is an article as an example.

Magnesium good for bones and teeth

Magnesium is important for calcium metabolism and this is helping your bones and teeth to stay strong. The bones store half of the body’s magnesium. Another location for magnesium are in our teeth.

Low levels of magnesium lead to osteoporosis, because one of the two structural components of bone (calcium and magnesium) is missing. In addition low magnesium causes inflammatory cytokines to increase. These break down bones. The Women’s Health Initiative showed that when daily magnesium intake exceeded 422.5 mg their hip and whole-body bone mineral density was significantly greater than in those who consumed less than 206.6 mg daily.

With regard to healthy teeth magnesium is important as it prevents periodontal disease.

This study found that there was less tooth loss and there were healthier periodontal tissues in 4290 subjects between 20 and 80.

Those who took magnesium supplements had healthier teeth.

Migraine sufferers improve with magnesium

A double blind randomized study showed that magnesium supplementation can reduce migraines. The researchers in this trial used 600 mg of magnesium supplementation for 4 weeks.

This reduced migraines by 41.6% in the magnesium group compared to the non-supplemented control group.

Another study showed that both intravenous and oral magnesium are effective in reducing migraine headaches.

Intravenous magnesium showed effects on improving migraines within 15 – 45 minutes. The authors concluded that one could supplement other migraine treatments with both oral and intravenous magnesium.

Too little magnesium can cause cancer

It may surprise you to hear that magnesium can even prevent some cancers. Two cancers have been studied in detail. I will limit my discussion to these two.

Pancreatic cancer

One study found that pancreatic cancer was reduced. Researchers recruited 142,203 men and 334,999 women between 1992 and 2000 and included them in the study. After 11.3 years on average 396 men and 469 women came down with pancreatic cancer. On the male side they found that when the body mass index (BMI) was greater than 25.0 there was a 21% reduction of pancreatic cancer for every 100 mg of added magnesium per day. There were a lot of smokers on the female side, which interfered with the study as confounding factors undermined statistical validity.

In another study, the US male Health Professionals Follow-up Study was examined after 20 years of follow-up. Those with a BMI of above 25.0 on magnesium supplementation had a reduced risk of pancreatic cancer. The pancreatic cancer rate in the higher magnesium group was 33% lower than in the lower magnesium group. The higher group consumed 423 mg of magnesium daily, the lower group 281 mg per day. It is significant that in both studies it was the heavier patients who came down with pancreatic cancer. It is common knowledge that obesity is a pancreatic risk factor.

Colorectal cancer

A study done on Japanese men showed that magnesium could protect them significantly from colon cancer.

Men who consumed the highest amount of magnesium developed 52% less colon cancer over 7.9 years. Researchers compared them to the group with the lowest 20% intake of magnesium. The women in this study did not reach statistical significance.

A study from the Netherlands examined colon cancer in patients. They found that only in patients with a BMI of greater than 25.0 magnesium did have protective effects. For every 100 mg of magnesium per day increase there was a 19% reduction of colon polyps. And there was also a 12% reduction of colorectal cancer for every 100 mg increase of magnesium per day.

Magnesium plays an important role in genome stability, DNA maintenance and repair. It also prevents chronic inflammation and reduces insulin resistance, all factors contributing to cancer reduction.

Live longer with magnesium

Consider that magnesium is the fourth most common mineral in the body. Add to this that magnesium is a co-factor of more than 300 enzymes in the body. Magnesium is an important co-factor in the conversion of chemical energy from food that we ingest. Magnesium is regulating blood sugar, blood vessel health and our brain electrical activity. 50% of our stored magnesium is located in our bones, which helps the strength and integrity of them.

Because of the distribution of the enzymes to which magnesium is a co-factor, virtually every cell in the body depends on our regular intake of magnesium.

Magnesium deficiency develops in older age

Since the 1950’s soils have lost magnesium where farmers grow vegetables and raise fruit trees. We simply do not get enough magnesium from food.

But chelated magnesium is freely available in health food stores. Take 250 mg twice per day, and you will have enough.

Because our metabolism slows down, there is a critical age where magnesium deficiency becomes more obvious than when we are younger. By the age of 70 there are 80% of men and 70% of women who do not get the minimum of magnesium-required amount they should get (350 mg for men and 265 mg for women).

Proton pump inhibitors lowering magnesium levels

At this age many people are on multiple drugs. For many proton pump inhibitors (PPI) are used to suppress acid production in the stomach. PPI’s have been associated with low magnesium blood levels. This link explains that when a patient takes PPI’s the total time of taking the medication should not exceed 1 year.

Low magnesium levels accelerate the aging process on a cellular level. Low magnesium levels increase senescent cells that can no longer multiply. Some of them could cause the development of cancer. These senescent cells also can no longer contribute to the immune system. This causes more infections with an adverse outcome.

Remember to take chelated magnesium capsules or tablets 250 mg twice per day and you will be protected from low magnesium levels in your body.

Here is why we live longer with magnesium supplementation

Our blood vessels will not calcify as early; they keep elastic for longer, preventing high blood pressure. Our kidneys will function longer with magnesium, preventing end-stage kidney disease. We need our kidneys to detoxify our system! More than 300 enzymatic reactions all over our body help that we have more energy and also help to prevent cancer. When there are fewer strokes and less heart attacks this helps reduce mortality. Magnesium supplementation helps to lessen the risk for Alzheimer’s disease and also reduces insulin resistance. Researchers have shown that this prevents Alzheimer’s disease.

The bottom line is we live longer and healthier; that is the meaning of longevity.

Magnesium Is Essential To Life

Magnesium Is Essential To Life

Conclusion

Magnesium is a key essential mineral. It balances calcium in the body and participates in many enzymatic reactions in the body as a cofactor. As long as we have enough of this mineral we won’t notice anything. It is with magnesium deficiency that things go haywire. Heart disease or a stroke could affect you . You could get kidney disease. And you could even get pancreatic cancer or colorectal cancer. If this is not enough, magnesium deficiency can cause diabetes, osteoporosis and bad teeth. You may suddenly die with no obvious cause. But, if balance your your magnesium blood level by taking regular supplements, you will carry on living and eliminate a lot of health problems.

Health Risks Of Night Shifts

One of the news stories in 2016 was about health risks of night shifts. The Bureau of Labor Statistics reported in 2000 that 15 million workers (16.8 % of the working population) were doing alternative shifts (night shift work mixed with daytime shifts). In 2016 they reported 14.8% were working alternate shifts. Among blacks, Asians and Latino Americans the percentage of working alternative shifts was higher, namely 20.8%, 15.7% and 16%, respectively.

Shift work is more common in certain industries, such as protective services like the police force, food services, health services and transportation.

Evidence of health risks of night shifts

1.There are several publications that showed evidence of health risks of night shift workers. Here is a random selection to illustrate the health risks of night shifts.A study from 2015 examined the sleep patterns of 315 shift nurses and health care workers in Iranian teaching hospitals. They found that 83.2% suffered from poor sleep and half of them had moderate to excessive sleepiness when they were awake.

2.This South Korean study examined 244 male workers, aged 20 to 39 in a manufacturing plant. Researchers compared blood tests from daytime workers to blood tests from night shift workers. They also obtained inflammatory markers like the C-reactive protein and leukocyte counts. Night shift workers had significantly higher values. The investigators concluded that shift workers have increased inflammatory markers. This is a sign of a higher risk of developing cardiovascular disease in the future.

Higher mortality and higher cancer risk in nighttime workers

3. A Swedish study found that white-collar shift workers had a 2.6-fold higher mortality over a control group of daytime white-collar workers.

4. Another study compared night workers in the age group of 45 to 54 with daytime workers and found a 1.47-fold higher mortality rate in the night shift workers.

5.In a study from China 25,377 participants were included in a study that investigated cancer risk in males with more than 20 years of night shift work. They had a 2.03-fold increased risk to develop cancer compared to males working day shifts. Women with night shift work in this study showed no effect with regard to cancer development.

BMI and estrogen levels higher in women nighttime workers

6.A Polish study examined hormones and the body mass index (BMI) among 263 women who worked night shifts and 269 women who worked day shifts. When night shift workers had worked more than 15 years at nights, their estrogen levels, particularly in postmenopausal women were elevated compared to the daytime workers who served as controls. The BMI was also increased in the nighttime workers.

Risk for chronic lymphocytic leukemia higher in nighttime workers

7.Chronic lymphocytic leukemia (CLL): a study in Spain showed that working for more than 20 years in rotating night shifts was associated with a 1.77-fold higher risk of developing CLL. The authors noted that melatonin levels in that group were much lower than in controls that worked only day shifts. Working in straight night shifts did not show higher risks of CLL compared to daytime workers.

8. In a Korean study from Seoul 100 female medical technologist who worked nighttime had their melatonin levels tested, which were compared to daytime workers.  They measured 1.84 pg/mL of melatonin for the nighttime workers compared to 4.04 pg/mL of melatonin in the daytime workers. The authors felt that this is proof that the diurnal hormone system has been disrupted. Altering the melatonin level also changes the circadian hormone rhythm.

Flatter cortisol curves at night in nighttime workers, also increased diabetes risk

9.A group of 168 female hospital employees doing rotating nightshift work in Southern Ontario hospitals were compared to 160 day workers. Cortisol production was assessed. Cortisol production in day workers and in shift workers on their day shift was similar. However, shift workers on their night shift had flatter cortisol curves and produced less cortisol. The authors felt that this disruption of cortisol production would explain why rotating night shift workers have a higher risk of cardiovascular diseases.

10.A Danish study with female nurses followed 28,731 nurses between 1993 and 2015. Researchers measured the incidence of diabetes in rotating nighttime nurses in comparison to the data from daytime nurses. Night shift workers had a risk between 1.58-fold to 1.99-fold when compared to daytime workers to develop diabetes. The risk for evening shift workers was less (between 1.29-fold and 1.59-fold).

Diurnal hormone rhythm behind health risks of night shifts

Your body has its own rules. It rewards you, if you sleep 7 to 8 hours during the night, but it will penalize you severely, if you turn it upside down. The reason is our built-in diurnal hormone rhythm. A peak of melatonin regulates sleep during the night. Melatonin is released by the pineal gland (on the base of the skull) when it gets dark outside. Daytime wakefulness regulates the release of the stress hormone cortisol from the adrenal glands. These two hormones inhibit each other, cortisol inhibits melatonin and melatonin inhibits cortisol. All the other hormones are also regulated according to the diurnal rhythm: testosterone is highest in the morning, human growth hormone is highest between midnight and 3 AM etc.

Adjustment of the diurnal hormone system

When you work daytime shifts, your diurnal hormone rhythm works just fine. But if you work nighttime shifts, your hormones have to adapt. This is very similar to traveling east or west where you cross several time zones. Your internal diurnal hormone system has to adjust to these changes. Typically it takes 1 day to adjust to a 1-hour time zone difference.

Rotating shift workers have the highest risk of getting sick

In people who work permanent night shifts, the hormone changes stay adjusted and there is no further switching. But most employers want to be “fair” to everybody, so they introduced the rotating night shifts. The publications above show that this is the worst thing you can do. It messes with your diurnal hormone rhythm, and some people never switch completely to the new hours worked. They don’t get enough daytime sleep because the kids are loud during the day etc. The rotating shift workers are running the highest risk of getting sick. The get cancer, diabetes, cardiovascular diseases, obesity, cancer, leukemia, and they have low levels of melatonin.

Health Risks Of Night Shifts

Health Risks Of Night Shifts

Conclusion

Shift workers working constant night shifts is less stressful than the more common rotating shift work. This is where you work night shifts for a period of time. Then the schedule switches to day shift, and you keep on rotating. The least health risks occur with regular daytime work. People exposed to rotating night shifts suffer from poor sleep. They have a higher risk of gaining weight, getting obese and acquiring diabetes in time. They are at a higher risk for heart attacks, strokes and cancer. All-cause mortality is about twofold higher than for workers who work day shifts.

The underlying problem seems to be a disturbance of the diurnal hormone rhythm. Normally this regulates our waking/sleeping rhythm and keeps us healthy. But with nighttime work melatonin production weakens, there is less cortisol production and hormone rejuvenation during rest periods suffers greatly. This weakens the immune system, allows cancer to develop and leads to chronic inflammation causing cardiovascular disease and diabetes. The remedy to prevent this from happening is to catch little naps whenever you can during the day. And, if at all possible, work daytime shifts permanently.

Arthritis Drugs Can Cause Heart Failure

The British Medical Journal has published a research articles in Sept. 2016 showing that arthritis drugs can cause heart failure. This occurs particularly in elderly patients around the age of 77 years and older. This is an age where arthritis is often causing pain, and people regulate the pain with over-the-counter pills. These anti-arthritis drugs belong into the group of anti-inflammatory drugs, called NSAIDs. This stands for “non-steroidal anti-inflammatory drugs”. The study was entitled “Non-steroidal anti-inflammatory drugs and risk of heart failure in four European countries…”

Arthritis drugs can cause heart failure shows study

The researchers followed adult patients above the age of 18 who started 27 different types of NSAIDs between 2000 and 2010. There were 92,163 hospital admissions for heart failure; the controls consisted of 8,246,403 patients not taking NSAIDs. 4 countries shared in this study providing 2.2 million patients from the Netherlands, 7.5 million from Italy, 13.7 million from Germany and 11.1 million from the United Kingdom.

Results of study

NSAID use of up to 2 weeks prior to assessment had a risk of 19% of resulting in a hospital admission for heart failure. A control group of patients who had not taken NSAIDs for at least 6 months or more had no hospital admission risk.

Seven traditional NSAIDs led to hospital admissions for heart failure. They were: diclofenac (brand name Voltaren), ibuprofen (brand name Motrin), indomethacin (brand name Indocin), ketorolac (brand name Toradol), naproxen (brand name Naprosyn or Aleve), nimesulide (brand name Mesulid and many others), and piroxicam (brand name Feldene). In addition two COX 2 inhibitors, etoricoxib (brand name Arcoxia) and rofecoxib (brand name VIOXX) were also having the same side effects.

Different risks of causing heart failure for different NSAID’s

The risk for heart failure was not the same for every NSAID. The risks ranged from 1.16-fold to 1.83-fold. Specifically ketorolac had a risk of 1.83-fold, indomethacin 1.51-fold, piroxicam 1.27-fold, diclofenac 1.19-fold, ibuprofen 1.18-fold, and naproxen 1.16-fold. Translated into common language it means that ketorolac had a risk of 83% of causing a hospital admission due to heart failure. In the case of ibuprofen it was only an 18% risk.

Some NMSAID’s doubled risk for heart failure

The risk for heart failure doubled for diclofenac, etoricoxib, indomethacin, piroxicam, and rofecoxib when used at very high doses. Doubling the risk means a 200% risk. Typically, when an arthritis patient has a flare-up of pain, the patient increases the NSAIDs dose. The patients usually take the higher dose for a longer time. Some NSAIDs had a significant risk for heart failure even at a medium dose. This was the case for indomethacin and etoricoxib. The good news was that celecoxib (brand names Celebrex and Celebra) at usual doses did not lead to an increased risk of heart failure.

Dose-response curves for toxicity of NSAID’s (exception: celecoxib, brand names Celebrex and Celebra)

Dose-response curves were obtained where possible. Here the researchers looked at the effect of low, medium, high and very high doses of NSAIDs in patients. Again heart failure occurrence was studied among those patients. The result clearly showed that low and medium doses of NSAIDs were fairly safe, but high and very high doses of NSAIDs caused heart failure. Etoricoxib, Piroxicam and Rofecoxib were particularly toxic in higher doses. Indomethacin was toxic at medium and high doses. An important exception to the rule was celecoxib (brand names Celebrex and Celebra), which did not cause heart failure, either at low doses or high doses. This is one of the most used NSAIDs, so it is fortunate that it does not cause heart failure.

Discussion of study

The authors of this study discussed why they believe heart failure is developing in patients who take NSAIDs. They argued that NSAIDs inhibit prostaglandin synthesis and the enzymes COX1 and COX2. This is how inflammation and pain gets inhibited, which is a good thing. But at the same time blood supply to the kidneys is reduced, kidney function is impaired, and sodium is retained. This is a bad thing as it leads to fluid retention and fluid overload of the heart resulting in heart failure. As the prostaglandin inhibition is dose-dependent, the authors said this is the reason that the heart failure rate is also dose-dependent when measured in large populations, as was done in this study. A noted exception, as already mentioned, is the popular celecoxib, which does not cause heart failure, even at high and very high doses.

Arthritis Drugs Can Cause Heart Failure

Arthritis Drugs Can Cause Heart Failure

Conclusion

This publication has a lot of statistical power as it was based on research in 4 European countries. It also involved almost 10 million subjects. The researchers compared them to an equally large control population. Because of the size of the study population it was possible to calculate risk ratios for NSAIDs causing heart failure for 27 different types of NSAIDs. Furthermore, the authors succeeded in quite a few cases to calculate risk factors for different concentrations of NSAIDs used. This statistical method is called a dose-response curve. It is a powerful pointer to toxicity when high doses cause heart failure, but low doses don’t.

The physician can use the information from this publication to select one of the NSAIDs that is least harmful. This would be a drug like celecoxib (brand names Celebrex and Celebra). The physician would tell the patient to use the least amount possible to minimize side-effects. Many aging arthritis sufferers will benefit from this. Hopefully the FDA will review this material and shut down the use of some of the more dangerous NSAIDs or force the manufacturer to attach a black box warning about the drugs that belong into this category. You should review what your favorite NSAID is and discuss this with your physician. Perhaps print a copy of this review and take it with you to your health provider. He may not have heard yet about the study.

Sugar Can Cause Heart Attacks

Recently an online medical journal article from JAMA has revealed that sugar can cause heart attacks. As the Guardian reports, this analysis of influence peddling of the sugar industry going back 60 years has had far-reaching effects by confusing the public and policy makers in the US and around the world. At the same time the interference of the sugar industry was protecting its own interests. It increased sugar sales, but made people sick with obesity, diabetes and cardiovascular disease. This story is similar to the tobacco industry that was able for years to cover up that cigarette smoke is causing heart attacks and lung cancer.

Denying that sugar can cause heart attacks

The English physiologist John Yudkin noted in the 1960’s that sugar was elevating cholesterol and triglycerides. The sugar industry panicked. They wanted to do something to stop this new type of research. As we can read online the Sugar Research Foundation (SRF) had 319 correspondences (1551 pages) with Roger Adams. He was a professor serving on the SRF’s scientific advisory board (SAB) from 1959 to 1971. Another piece of evidence of influence peddling came from a review of correspondence between the SRF and D. Mark Hegsted. He was professor of nutrition at the Harvard School of Public Health. At the same time he was co director of the SRF’s first coronary heart disease research project. This took place from 1965 to 1966.

Historic falsification of research findings by John Yudkin

There are 27 documents totalling 31 pages in the Harvard medical Library. It is clear from this correspondence that the SRF was looking for a way to undermine the new research findings of negative effects of sugar. The SRF was looking for a way to confirm that fat reduction would be beneficial for patients. This way physicians would put many people on a low fat diet. This in turn would ensure continuing and rising sales of sugar.

New evidence that sugar can cause heart attacks

New research came out by D. Mark Hegsted in the Annals of Internal Medicine in June 1965. It linked sugar consumption to cardiovascular disease. It noted that blood sugar levels were a better predictor of hardening of arteries than cholesterol levels or high blood pressure. Another paper stated that it was sugar rather than starches causing high triglycerides in the blood. He hypothesized that “perhaps fructose, a constituent of sucrose but not of starch, was the agent mainly responsible.” An editorial in the same publication noted that these new findings corroborated Dr. Yudkin’s previous research that sugar could cause heart attacks.

The sugar industry was very concerned about these studies. If publicized widely, it would have the capacity to lower sugar sales.

Sugar can cause heart attacks, but review paper ignores this

On July 1, 1965, the SRF’s Hickson visited D. Mark Hegsted to discuss his publication. He wanted him to be part of an extensive literature review that would show that it was too much saturated fat that was the cause of high cholesterol and triglycerides, not sugar. It also should state that a lowering of fat content from 40% to 20% was necessary and that polyunsaturated fatty acids should be used to replace much of the fat. The fact that the food industry would quietly increase sugar content in processed foods was not mentioned. The review paper was called “Project 226”. It resulted in a 2-part literature review by McGandy, Hegsted, and Stare. It was entitled “Dietary Fats, Carbohydrates and Atherosclerotic Disease,” and was published in the New England Journal of Medicine (NEJM) in 1967. Industry and non-industry funding of the review authors’ experimental research was disclosed.

Falsified study from 1967 in the New England Journal of Medicine

However, the funding by the Sugar Research Foundation was omitted. The authors of the study received handsome amounts of money from the SRF for their efforts. The story that was told is all too well known, but false. There was the claim that the medical literature would have shown that a reduction of saturated fat intake lowered cholesterol. Triglyceride levels did not matter. Only cholesterol levels counted with respect to coronary artery hardening. There was also the statement that replacement of saturated fat with polyunsaturated fatty acids like corn oil would be beneficial in reducing heart attack rates.

Effect of the literature review on heart attack rates

Sadly the NEJM literature review has resulted in a government policy that lasted for decades. The gospel was that a low fat diet would prevent heart attacks. The food industry prepared foods that were low in fats and high in sugar and supposedly healthy. But the extra sugar made people fat, it did not decrease heart attack rates, but made them more frequent. Strokes were also on the rise and diabetes has become rampant. The reliance on corn oil has introduced another problem: omega-6 fatty acids are now consumed at an alarming rate. Corn oil has a 1:59 ratio for omega-3 to omega-6 fatty acids.

Corn oil causes inflammation

This means that corn oil contributes to the lack of omega-3 fatty acids in our food. When the ratio of omega-3 to omega-6 fatty acids falls below 1:3 or 1:4 the metabolism changes towards inflammation as the arachidonic acid system switches toward inflammation. Cardiologists have pinpointed inflammation as an important cause of hardening of arteries. Fish oil, a rich source of omega-3 fatty acids helps to prevent hard attacks and strokes.

The end result of the confusion regarding fat, sugar and heart attacks caused by the biased literature review meant misery, suffering and death for many for decades. But recently there has been a renaissance of Dr. John Yadkin’s research: Now it is clear what sugar is doing and how it affects our health.

How sugar can cause heart attacks and more

It is clear that sugary soda has detrimental effects on us: as little as one or two cans of sugary soda drinks per day lead to

  • 26% greater risk of developing type 2 diabetes
  • A 35% greater risk of heart attack or fatal heart disease
  • A 16% increased risk of stroke

Dr. Frank Hu’s study

Dr. Frank Hu has participated in a study that spanned over 24 to 30 years and examined the replacement of saturated fat with polyunsaturated fatty acids (PUFA), monounsaturated fatty acids and whole grain carbohydrates. The study involved 84,628 women (Nurses’ Health Study, 1980 to 2010), and 42,908 men (Health Professionals Follow-up Study, 1986 to 2010). The researchers did detailed diet assessments every 4 years. 7,667 cases of cardiovascular disease (CHD) occurred during the study. Compared to controls that did not change their diet with respect to saturated fatty acid intake, those who replaced with PUFA had 25% less CHD, those who replaced with monounsaturated fatty acids had 15% less CHD and those who replaced saturated fatty acid intake with whole grains had 9% less CHD. In contrast, a subgroup that had replaced saturated fatty acid intake with carbohydrates from refined starches/added sugars ended up with a 10% increase of CHD.

Effect of sugar

We know now that sugar can increase cholesterol and triglycerides as Dr. John Yudkin has said in the 1960’s.

We also know that sugar can cause arthritis when combined with low omega-3 fatty acids and high omega-6 fatty acids. In the 1950’s Dan Dale Alexander wrote a book called “Arthritis and common sense”. The medical establishment did not accept that simple remedy and Dan Dale Alexander was classified as a “quack”. However, Dr. Mirkin describes a study from Berlin that later confirmed that Dan Dale Alexander’s observation was correct: an emulsion made by shaking orange juice with cod liver oil and taken three times per day on an empty stomach would indeed improve osteoarthritis.

High glycemic foods and starchy foods cause cancer

High glycemic foods (sugar, starchy foods) caused breast cancer, colorectal cancer and endometrial cancer. The majority of trials showed this association although not all. The more obese patients were, the more pronounced the insulin resistance was and the more the relationship to these cancers became apparent. A diet that is high in starchy foods like potatoes, rice and bread is causing pancreatic cancer as was shown by researchers at the Dana-Faber Cancer Institute, Brigham and Women’s Hospital and Harvard School of Public Health.

Sugar Can Cause Heart Attacks

Sugar Can Cause Heart Attacks

Conclusion

The low fat/ high glycemic diet was a fad-diet based on fictitious science, sponsored by the sugar industry. It became a human experiment and resulted in 60 years of suffering. During that time it became apparent that this diet did not work. It caused the obesity wave, a wave of heart attacks, strokes and cancer. This was all caused by too much sugar in the diet. Associated with this are the consumption of processed foods. There is too much sugar and an abundance of omega-6 fatty acids in processed food. This causes inflammation and hardening of the arteries.

What sugar does

We finally know that sugar raises cholesterol (LDL cholesterol in particular) and triglycerides. This leads to fat deposits and hardening of the arteries resulting in strokes and heart attacks. Remove refined sugar, limit your starchy food intake and eat fish as a source of omega-3 fatty acids. Feast on vegetables, salads and have some nuts as another source of omega-3 fatty acids. You are well on your way to preventing heart attacks, strokes and many cancers. After reading all the facts, there is no need to be a victim of the sugar industry. This also helps you to stay away from sugar’s associated health risks.

Seven Steps To Live Over 100 Years

Forbes invited me to publish a blog I wrote for Quora, “Seven steps to live over 100 years”.

The topic of habits by people who live more than a hundred years has been reviewed many times in the media. It continues to be popular. Here are seven things you can do to stay healthy followed by an explanation why.

Seven steps to live over 100 years – step1: Stay active

You want to stay active every day, even if you retire. You want to move and keep your mind busy. Part of that is to do a daily formal exercise routine to keep those muscles toned, which will prevent falls in the future.

Explanation: when you keep your muscles toned and you move about, your balance organ and coordination remains sharp, you are less likely to fall and break a hip. 50% of those who sustain a hip fracture die.

Seven steps to live over 100 years – step 2: Eat a healthy diet

Eat a Mediterranean type diet or follow the Okinawan diet. These diets contain less meat (or no meat as in the Seventh Day Adventist diet), but lots of vegetables and fiber. This keeps your cholesterol down, your arteries open and your metabolism controlled, preventing diabetes. If you are not obese and you have no diabetes, you are going to be OK with your cardiovascular system for decades to come.

Explanation: Heart attacks are still on top of the mortality list. Avoid them and you got it made, if you want to make it to 100 and beyond. But we need to stay away from the poor fats and the obsession about eating beef. Red meat, if eaten too often gives you a higher risk of getting cancer and heart disease. So eat it only once a week at the most, the rest would be chicken, turkey meat or fish. Nothing wrong with a vegetarian meal, let’s say kidney beans or lentils on a day in between. This still gives you protein for your muscles, but spares you a heart attack.

Seven steps to live over 100 years – step 3: Take care of your teeth

Brush your teeth and floss every day. This will control the bacteria in your mouth and prevent leakage into your blood affecting your heart valves. Studies have shown that this prevents heart attacks.

Explanation: When I heard this first about 20 years ago, I found it strange. But the literature is clear: chronic gingivitis is associated with bacteria that grow on the gums and spread into your blood. They can then colonize your heart valves and even the lining of the arteries, particularly where there is already hardening of the arteries (arterial plaque). This can lead to heart valve disease like mitral valve disease or heart attacks.

Seven steps to live over 100 years – step 4: prevention of disease

See your physician right away if there is a new skin lesion or anything that is different on your body. Removal of early cancer and treatment of any early medical condition is always easier to treat than waiting until it is out of control. Particularly with cancer treatment at an early stage, which usually involves only a small surgical procedure, this will reward you with a ripe old age.

Explanation: I learnt this point in general practice. Patients who waited until small problems become big problems were always much worse off than patients who saw me for small problems that we could remedy at an early stage. As mentioned above this is particularly important in cancer cases, as usually stage 1 and 2 of a cancer is curable with surgery. Once you get lymph node metastases and distant metastases, the cancer is much more difficult to treat, if at all. This is a principle that is pretty much true for any disease. The prevention factor is huge. Make use of it!

Seven steps to live over 100 years – step 5: Lifestyle matters

Watch excesses like smoking (cut it out!), alcohol intake, and recreational drugs. Smoking causes heart attacks, strokes, and cancers, which shorten your life. Recreational drugs just interfere with your body chemistry and have side effects. Cut them out, if you cherish growing older than 100. Alcohol needs to be kept at a very low consumption, if you want to preserve your liver, which is your central metabolic organ. If you can’t handle moderation with alcohol consumption, cut it out. No one has died from not consuming alcohol.

Explanation: I have already explained why lifestyle choices matter. The alcohol question is one that will be discussed back and forth for centuries. There are cardiologists who tell you that men should drink 1 to 2 drinks per day and women 1 drink per day and we all live longer, because of prevention of heart disease. The wine industry makes sure that you will hear this cardiology rule. It is true that centenarians often drink one glass of red wine per day. But there are plenty of centenarians who never drank in their life. It is a matter of personal choice.

Seven steps to live over 100 years – step 6: Avoid obesity and diabetes

I did mention to avoid obesity under point 2 above, which is associated with metabolic syndrome and diabetes. Your ideal body mass index should be in the 21 to 22 range. You can achieve this by following the diets I mentioned above. You should cut out sugar and starchy foods.

Explanation: I have followed such a diet since 2001 and my body mass index is between 21 and 22. I grew up in Germany where an emphasis was put on sweets and starchy foods. Needless to say my modified Mediterranean diet deviates from the good old German diet significantly. I find healthy food very tasty.

Seven steps to live over 100 years – step 7: Sleep and hormones

Getting sleep regularly, having an optimistic outlook on life, and having good relationships help to keep the immune system strong and keep your hormones balanced. This in turn will keep you healthy emotionally and physically.

Explanation:

There are two comments I like to make. One is that when you have calm nerves, and your emotions are in balance, your stress hormones are under control. We know that people who are content and easy going live longer. The type A personality is the one who gets a heart attack.

The other point is that hormones have running times. When they start missing, we get menopause or andropause. When we are in our 50’s it is time to have your hormones checked by a knowledgeable health practitioner (naturopath, anti-aging physician). At this point regular physicians are mostly lack education about bioidentical hormone replacement. I mention this as in European studies it has been shown that replacement of missing hormones with bioidentical hormones resulted in more youthful lives. You can extend your life expectancy by 15 years using bioidentical hormones according to Dr. Hertoghe, an endocrinologist in Belgium.

Seven Steps To Live Over 100 Years

Seven Steps To Live Over 100 Years

Conclusion

People have had a long time fascination about the factors that lead to a healthy age above 100 years. I am suggesting that you concentrate on enjoying your life and keeping toxins out. Engage in some form of exercise or stay active all the time. Adopt a healthy diet. This is where perhaps most people go wrong. They think they can go on pouring junk foods and alcohol down their throats and never get heart disease or cancer. The truth is not quite like that. We do need to adopt a healthy diet like the Mediterranean diet. We also need to limit drinking to a healthy level. Replacing missing hormones with bioidentical ones will prolong your life as well. Given these recommendations, happy journey to 100 and beyond!

New FDA Food Guidelines

A recent news release describes 2016 new FDA food guidelines. In it the FDA recommends to double the amount of seafood (fish and shellfish) as well as to cut down saturated fat and sugar. Coffee, which was labeled a culprit in the past is now recommended to a total of 400 mg of caffeine per day as it is heart protective. Cholesterol is no longer considered an enemy, but sugar, saturated fats and trans fats are.

Here is a breakdown of what each of these recommendations means.

New FDA food guidelines regarding increasing fish and shellfish

The anti-inflammatory effects of omega-3 fatty acids have finally entered the recommended diet plan of the FDA. This reflects the nutritional research over the last few decades that noticed a longer life expectancy for people who eat more seafood and less red meat.

The only problem with seafood can be its mercury contamination. The higher predator fish are in the food chain, the more contaminated fish meat is. The FDA recommends to avoid tuna fish as a food source, as it is very high in mercury. An exception is canned tuna as it has been washed and some of the mercury got lost in the food processing. Wild salmon, sardines and oysters are low in mercury and good sources of omega-3 oils.

New FDA food guidelines regarding reduction of saturated fat

The FDA now recommend to reduce saturated fat to 10% of the total daily caloric intake. This is not undisputed as some studies show that saturated fat may not be involved in the production of hardening of the arteries. Other studies have shown that breast cancer is more common when more saturated fat is consumed.

When the news came out in the 1980’s that saturated fats would be bad for arteries, there was a switch to polyunsaturated acids: safflower oil, canola oil, sunflower seed oil, corn oil and soybean oil or grape-seed oil.

However, the irony is that these vegetable oils were highly unstable and led to oxidation causing heart disease and cancer.

In contrast olive oil is a much more stable oil. In the Mediterranean olive oil associates with longer lives.

New FDA food guidelines regarding protective effect of coffee

In the past few years many studies have shown the coffee consumption prolongs life. The FDA has now officially recognized these studies and recommends that consumption of up to 400 mg caffeine will help promote health. On the other hand the FDA also recommends that those who do not drink coffee, should not change their lifestyle just because of these recommendations.

New FDA food guidelines regarding sugar reduction

An entirely new recommendation of the FDA says to reduce sugar in anybody’s diet. The FDA explains that too many processed foods contain sugar. Food merchants  add sugar in drinks like coffee, fruit juices, food items like muffins and cakes.

In the past decades it has become clear that sugar much more so than fat is the culprit. It is sugar and starchy food that causes hardening of arteries. The liver metabolizes sugar into triglycerides and LDL cholesterol. Elevated triglycerides and LDL cholesterol levels lead to deposited into arteries and fatty tissue. In this context it makes sense that the FDA now recommends a reduction of sugar intake.

 New FDA food guidelines regarding cholesterol

In the past scientists thought that cholesterol in meat would be the cause of high cholesterol in the blood. This was an oversimplification. We now know that only a small portion of the blood cholesterol comes from food sources.  Cholesterol from food sources is no longer of importance with regard to risks for heart attacks and strokes. It is sugar and too many starchy foods (bread, pasta, pizza, muffins, cakes cookies) that the body digests into sugar. This accounts for high cholesterol, as the liver metabolizes sugar into LDL cholesterol and triglycerides.

New FDA Food Guidelines

New FDA Food Guidelines

Conclusion

The new food guide by the FDA has fundamentally changed the previous recommendations based on newer nutritional studies. Now the FDA says to double fish and shellfish in comparison to previous recommendations. Coffee is no longer the enemy, but your friend. You need to avoid sugar and starch over consumption, as this can raise cholesterol and triglyceride levels. Eat more vegetables and fruit. These recommendations closely resemble a Mediterranean diet, which several studies tell us prolong life. Abandon the American Standard diet with hamburgers, processed foods and sugary drinks. Pay attention to the FDA food recommendations!

Prevent Unhealthy Aging

We know that stress can age you prematurely, but what do we need to do to prevent unhealthy aging? This is exactly what this review by cardiologist Dr. Joel Kahn has done. It points out that the right lifestyle makes the difference.

Studies showing how to prevent unhealthy aging

Several studies have shown how to avoid getting heart disease, cancer and diabetes.

2001 Harvard lifestyle study

Kahn reported that in 2001 the Harvard School of Public Health published a study where 84,941 healthy female nurses had been followed who were free of heart disease, cancer and diabetes at baseline. But only 3.4% of the 84,941 women managed to stay healthy after 16 years of the study. The secret? Their body mass index (BMI) was less than 25.0, their diet was high in polyunsaturated fat and fiber, low in trans fat and low in glycemic load, they engaged in regular moderate exercise with a minimum of 30 minutes per day; they did not smoke and they drank ½ an alcoholic drink per day. Their risk to get diabetes was 91% lower than the rest of the study. This shows you how powerful lifestyle choices are; it shows us how to prevent unhealthy aging.

INTERHEART study

In 2004 an international study (the INTERHEART study) reported in the Lancet the lifestyle of 15,152 cases that developed heart attacks in 52 countries with 14,820 controls who did not have heart attacks. The researchers found 9 risk factors that accounted for 90 to 95% of the heart attacks. They were smoking, cholesterol risk ratio elevation, diabetes, high blood pressure, abdominal obesity, stress, low intake of fruit and vegetables, high alcohol intake and lack of physical exercise. Obesity counted as a risk factor when the waist circumference measured more than 35 inches in a woman or more than 40 inches in a man. Lifestyle changes could eliminate all these 9 risks.

2006 Health Professional Study

The 2006 Health Professional Study spanned over 16 years in a group of 40 to 75 year old doctors without a heart attack at baseline. It noted that male doctors who were lacking the 5 heart attack risk factors had 87% less heart attacks than controls without health lifestyles. What were the lifestyle factors? A body mass index (BMI) of less than 25, being a nonsmoker, being physically active for more than 30 minutes a day, having not more than moderate amounts of alcohol intake and having a diet that was more than 40% plant based.

2007 Swedish study

In 2007 a Swedish study reported on 24,000 women after menopause that had no heart attacks initially. After 6 years of follow-up 308 women developed heart attacks. An analysis showed what the risk factors were for those who developed heart attacks. Those who did not have these risk factors reduced their risk of getting a heart attack by 92%. What lifestyle factors were protective? Four factors were identified: a low-risk diet (consisting of high vegetable and high fruit intake, whole grains, legumes, fish and moderate alcohol intake), not smoking, walking or biking 40 minutes daily and a low waist circumference.

2008 Harvard study (follow-up to 2001 study)

In 2008 the Harvard University released a study that was a further follow-up of the Health Professional study with more than 43,000 men and also the Nurses’ Health Study with more than 71,000 women. The question here was what would prevent the development of strokes? The investigators found that in both groups stroke risk reduction by 50% was achievable with the following 5 lifestyle factors: no smoking, keep the BMI below 25, exercise at least 30 minutes daily with moderate activity, don’t exceed a modest alcohol intake and have a diet intake in the top 40% of fruit, vegetables and whole grains. This, too shows us how to prevent unhealthy aging.

2014 study from the Netherlands

A 14 yearlong study from the Netherlands was published in 2014, where almost 18,000 men and women without heart disease at the beginning of the study were followed. More than 600 heart attacks occurred throughout the study. People who stuck to 4 lifestyle habits reduced their heart attack rates by 67%; if they adhered to 5 lifestyle factors they reduced the heart attack rate by 83%. The 4 initial lifestyle factors were: doing an average of 30 minutes of physical activity per day, eating a Mediterranean style diet rich in fruit and vegetables and whole grains, not smoking and having more than one alcoholic drink per month. This gave you a reduced risk of your heart attack rate by 67%. Add one more good habit: sleep 7 or more hours per night on average. This reduces the risk of you getting a heart attack by 83%!

Swedish heart study (more than 20,000 men)

A Swedish heart study with initially more than 20,000 men was going on for 11 years.  The investigators identified 5 lifestyle habits as essential to reduce heart attack rates. Unfortunately only 1% of the study group adopted all 5 lifestyle factors, but they dropped their chance of getting a heart attack or dying of a heart attack by 86%. The lifestyle factors were: a diet rich in fruit and vegetables, legumes, nuts, whole grains and low fat; not smoking, moderate alcohol consumption, thin waistline and more than 40 minutes of physical activity. All of this demonstrates to us how to prevent unhealthy aging.

Preserving health and vitality to prevent unhealthy aging

There is a clear pattern in all of these large studies. A healthy lifestyle preserves your health by keeping your joints and muscles in good working order. When you engage in cardiovascular training every day,  your heart and lungs will work at their best capacity. This keeps your nitric oxide going, which is an important signalling molecule that in turn reduces your blood pressure.

When we remove disabling diseases like strokes and heart attacks and prevent diabetes from developing, life expectancy is increasing. There will be fewer disabilities and less frailty when people remain physically active even in old age. By adhering to good lifestyle habits even Alzheimer’s disease occurs less often.

Prevent Unhealthy Aging

Prevent Unhealthy Aging

Conclusion

The studies cited here show how lifestyle factors can make a significant difference in preventing heart attacks and strokes. In the past even doctors ignored the risk of smoking. A few years back conventional medicine negated that lifestyle factors could make a difference. Now we have more studies than we need to prove that this is so. It is more important that we adhere to as many of the lifestyle factors identified in these studies to make a real difference in our lives. We also need to set an example to the next generation and to our peers. Adopting healthy lifestyle factors has to become a cultural habit for society at large. This will help reduce healthcare costs, but most importantly this will help you and me to live longer, healthier lives. It will help us to prevent unhealthy aging.

Hormone Replacement Therapy In Menopause

Back in the 1980’s many physicians were hopeful that hormone replacement therapy in menopause (HRT) could extend the lives of postmenopausal women by approximately 10 years, if HRT would be started early enough. But the HERS study (Heart and Estrogen/progestin Replacement Study) in 1998 and the WHI study (Women’s Health Initiative) of 2002 changed things dramatically.

The HERS study did not show any benefit with regard to prevention of heart disease. Instead it showed more gallbladder disease (1.38-fold) and blood clots (2.89-fold) develop in the experimental group versus the placebo.

The WHI study was complex and had several arms. There also were some methodological errors in the study as pointed out here.

Instead of a decrease in heart attacks, there was an increase, when estrogen and progestin was combined. There were more cases of colon cancer, more blood clots and heart attacks in the placebo groups compared to the experimental groups. It seems that something went wrong with these trials.

Unknown facts about hormone replacement therapy in menopause

Premarin is not bioidentical to human estrogens

Both clinical trials used the wrong hormones to do the trials. If you use the wrong hormones in a trial, you would expect to get the wrong test results. Horse derived estrogen (equine estrogen) is hardly a match for bioidentical, human estrogen in women. But decades ago the drug manufacturer had decided that estrogen was easiest to manufacture on a large scale when urine from pregnant mares was used. The product contains conjugated horse estrogen and is known by the name Premarin. Premarin is not bioidentical to human estrogens.

Synthetic progesterone causes heart attacks

The other hormone, medroxy progesterone (MPA) is a progestin, a bad copy of the bioidentical progesterone that a woman’s corpus luteum of one of her ovaries produces. This is in the second half of her menstrual cycle. During pregnancy the placenta produces lots of progesterone to protect the pregnancy. As Dr. Masley, a cardiologist stated synthetic progestins cause heart attacks, while progesterone does not. Masley said: “Medroxy progesterone (MPA) increases the risk for heart disease and for breast cancer. I can’t understand why any physician would recommend medroxy progesterone during menopause, but it is still in use.”

Don’t use estrogen orally, but only by estrogen patch or estrogen cream

Next there is the question whether the liver changes the composition of an oral hormone tablet metabolically or not. The answer is: yes! Dr. Masley stated in the link above that oral estradiol, when compared to estrogen rubbed onto the skin, increases levels of inflammation by 192%. The C-reactive protein (CRP) can be measured with a blood test. The risk for a blood clot increases by 400%. A woman using estrogen should always use the estrogen patch or an estrogen cream with bioidentical estrogen to avoid these complications.

Measure hormones, don’t estimate

Measure hormones – don’t estimate: Hormones are constantly changing and if you don’t measure, you don’t know what you are dealing with. Dr. John Lee showed a long time ago that you should measure hormones and identify those women who are truly hormone deficient. These are the ones who need hormone replacement. However, you use only bioidentical hormones to replace and you replace only as much as is needed to normalize the levels. This is also the level where postmenopausal symptoms disappear. Lee noted: “A 10-year French study of HRT using a low-dose estradiol patch plus oral progesterone shows no increased risk of breast cancer, strokes or heart attacks.”

Measure progesterone hormone levels only in saliva

The elusive progesterone: when the physician measures progesterone as a blood test, it may come back as high while it can be low in a saliva hormone test in the same woman. Dr. Lee has pointed out that studies have shown that progesterone levels in tissue are usually higher by several factors when compared to blood levels and that blood levels are not reliable predictors of tissue levels (Ref.1). On the other hand he found that saliva levels have a good correlation with tissue levels in organs like the ovaries or the uterus. Dr. Lee preferred saliva hormone tests for this reason. When it comes to progesterone levels you can trust saliva test, but you cannot trust blood tests. Many physicians ignore that fact and strictly order blood progesterone levels coming to false conclusions.

Progesterone to estradiol ratio

We know that estrogen and progesterone must be balanced to avoid troubles of developing heart attacks or cancer. The link of Dr. Lee above stated that women without breast cancer have saliva progesterone hormone levels that are more than 200-fold higher than the saliva estradiol levels. On the other hand women with breast cancer have a ratio of less than 200 to 1 with respect to progesterone to estradiol saliva levels. There is a similar ratio in men. Here the ratio of testosterone to estradiol must be larger than 20 to 1. If this is not the case, he is at a higher risk of developing prostate cancer. Unfortunately many older men, when overweight or obese, have high estrogen levels and the ratio is less than 20 to 1.

Bioidentical hormones can prevent heart attacks and strokes

Masley has mentioned that in the first 6 years after menopause using a topical form of estrogen and micronized progesterone as tablets can minimize the risk of future heart attacks and strokes. But after 10 years it is less obvious what is the best solution. The question is what type of estrogen application is used. Is it estradiol or is it Bi-Est or Tri-Est, which are other topical estrogen applications. Tri-Est is 80% estriol, 10% estrone, and 10% estradiol while Bi-Est is 80% estriol and 20% estradiol. Tri-Est in particular would be very close to the natural composition of estrogens in a woman’s body.

What to do after 10 years of hormone replacement therapy in menopause

Given the insecurity what to do after 10 years of menopause, my suspicion is that there are other factors that play a role with respect to hormone replacement. A lot of women have extra pounds accumulated. Fatty tissue contains an enzyme called aromatase.

This makes estrogen from androgenic hormones including testosterone. The adrenal glands situated above the kidneys produce these hormones in menopause. The more overweight or obese a postmenopausal woman is, the higher the estrogen levels in her blood because of the action of the aromatase. Most physicians have not measured hormones in the past, but just replaced hormones monitoring only postmenopausal symptoms. This is changing. What I said under point 4 above is happening more.

Bioidentical hormone replacement practiced by naturopaths

Naturopaths tend to be more comfortable with bioidentical hormone replacement the way I have described it. If you did hormone tests (preferably saliva hormone tests) you would pick up higher estrogen levels and low progesterone levels with unfavorable progesterone to estrogen ratios as mentioned. These women do not need estrogen (they have it already in their systems). They need progesterone replacement only. A woman can take progesterone by mouth as micronized bioidentical progesterone capsules at night. It also  comes as bioidentical progesterone cream for application to the skin. Here is another take on the use of bioidentical hormones.

Hormone Replacement Therapy In Menopause

Hormone Replacement Therapy In Menopause

Conclusion

Bioidentical hormone replacement is complex. It requires some basic knowledge of the facts mentioned above. I find it surprising that two separate research groups could not free themselves of the Big Pharma grip. In not doing so they unwillingly produced studies showing all of the undesirable side effects of using artificial hormones. When manufacturers modify natural hormones with unnatural side-chains, the end products are synthetic hormones. These do not fit the appropriate natural hormone receptors. The anti-aging community as represented by the A4M group (American Academy Of Anti-Aging Medicine) with more than 25,000 physicians worldwide has been saying this all along. Now we know that it is really true. Use hormone replacement knowledgeably and use bioidentical hormones!

Healing Powers Of Green Tea

Powerful catechins that are a special form of bioflavonoids provide the healing powers of green tea. Researchers have proven that these catechins are only in green tea, not so much in black tea. The most effective of several catechins contained in green tea is EGCG, which stands for EpiGalloCatechin-3-Gallate. It crosses the blood/brain barrier and is very important for the protection of the brain from Alzheimer’s disease. But green tea or green tea extract has a diversified pharmacological action. Researchers said that green tea protects you from cardiovascular disease, from obesity, from diabetes, from autoimmune disorders, from cancer, from Alzheimer’s and dementia.

In the following I like to comment on how green tea or its extract can protect from all of these diseases.

Alzheimer’s disease

Although there are 5 or 6 approved anti-Alzheimer’s drugs, none of them work for very long. They may at best postpone the deteriorating memory for 6 months, but then the effect of the drug wears off. The reason is that the drugs do not stop the production of the deadly beta-amyloid. It is the beta-amyloid that damages nerve cells that you want to preserve so you can think and memorize. In contrast a simple phytochemical, the catechin EGCG has been shown in animal experiments and in human trials to stop beta-amyloid production and increase solubility of beta-amyloid fragments in the brain. The end result is better memory and no further deterioration.

Two studies showing less strokes and better working memory processing with green tea

In a study of 13,988 elderly Japanese observed over 3 years the group that consumed 3 to 4 cups of green tea daily had 33% less strokes, cognitive impairment and osteoporosis.

Researchers at the University of Basel, Switzerland enrolled 12 healthy volunteers aged 21 to 28 and fed them extracts of green tea or placebo fluid via feeding tubes. They did this to rule out taste as a factor. The patients underwent functional MRI scans and they also received memory-stimulating tasks. Only the green tea extract was boosting activity in the frontal brain of the subjects. This was located in a specific area, called dorsolateral prefrontal cortex. This area has a connection with language comprehension, reasoning and learning. It also switches short-term memory into long-term memory, called working memory processing.

Healing powers of green tea through new nerve cell development

Researchers showed with animal experiments that green tea extract protects nerve cells from the toxic effect of beta-amyloid. At the same time green tea extract triggers the production of new brain nerve cells (neurons). This is really good news for Alzheimer’s disease patients and their families: green tea extract delays further memory deterioration and stimulates the development of new nerve cells in the brain!

Cardiovascular disease

In a 2006 Japanese study 40,530 Japanese adults aged 40 to 79 years without history of stroke, coronary heart disease, or cancer at baseline were observed for 7 years. Diaries were kept about how many cups of green tea each person was drinking per day. The prevention of heart attacks and strokes was the the biggest effect of green tea extracts.

Men had a mortality reduction of 12% for heart attacks when they drank 5 cups or more of green tea; in women the corresponding mortality reduction for heart attack was 31%, a bigger effect. Overall mortality from strokes was lower than from heart attacks. This made the effect of green tea consumption even more beneficial with respect to stroke prevention. This study did not show any cancer prevention effect for green tea.

Obesity

It appears that green tea increases heat production and burns fat in the process. There was a small effect in terms of weight loss and a beneficial effect increasing the protective HDL cholesterol in this 2012 Polish study on obese patients. The authors compared either 379 mg of green tea extract, or a placebo, daily for 3 months. They concluded: “The results of this study confirm the beneficial effects of green tea extract supplementation on body mass index, lipid profile, and total antioxidant status in patients with obesity.”

Diabetes

Although there are claims in some studies that green tea would prevent diabetes, this question was thoroughly investigated in this Chinese 2014 study.

Researchers did not see any effects on fasting blood sugars or on hemoglobin A1C values. Hemoglobin A1C is a very sensitive indicator for the presence or absence of diabetes. All these lab tests showed no change following consumption of green tea or green tea extract. Forget using green tea for diabetes prevention; cut out sugar and starchy foods instead.

Autoimmune disorders

Sjogren’s syndrome and lupus are both autoimmune diseases. Green tea extract has shown in humans that symptom severity can improve; green tea polyphenols (GTPs) possess anti-inflammatory properties that benefit patients with autoimmune diseases.

In an animal model arthritis researchers determined that T helper cells are weakened and bone resorption is inhibited by EGCG from green tea extract.

Researchers at Harvard Medical School, Boston, MA have noted that green tea extract is useful in calming down the immune response in autoimmune diseases. They concluded: “Altogether, these studies identify and support the use of EGCG as a potential therapeutic agent in preventing and ameliorating T cell-mediated autoimmune diseases.”

Cancer

Many researchers found that EGCG from green tea extract has immune modulatory effects. Furthermore, they saw a positive effect when patients received EGCG in combination with chemotherapy. A combination of cisplatin therapy with green tea extract has been found to have more effects on colorectal cancer and ovarian cancer than each one on its own. Similarly chemotherapy of breast cancer had better results in humans when EGCG from green tea extract was added as an immune modulation. More research, particularly in humans is needed to fully understand the mechanism of action of EGCG.

Toxicity of green tea extract

Animal experiments showed that higher doses of green tea extract could cause toxicity in the liver and in the nose of rats and mice. I was not able to find objective evidence for green tea toxicity in the PubMed system with respect to humans.

Conclusion

Perhaps the most important discovery regarding green tea extract is as follows. It crosses easily through the blood/brain barrier into the brain. This can postpone Alzheimer’s disease and can even lead to new neuron formation. The beneficial cardiovascular effects are also useful and combine well with exercise and good nutrition for prevention. Particularly stroke prevention is a useful property of EGCG from green tea extract. The effect on obesity is marginal whereas there was no effect of green tea on prevention of diabetes. The immune modulatory effect of green tea extract is useful in the treatment of autoimmune diseases and of cancer. Existing treatments for these conditions are becoming more effective by adding green tea extract.
