Olive Oil Combats Inflammation

By | Health, Nutrition, Prevention

The health benefits of the Mediterranean diet have received a lot of positive press, and so far the benefits have been credited to fresh fruit and vegetables, as well as olive oil. It has been pointed out that the bioflavonoids in fruit and vegetables are the positive forces at work. Also, the monounsaturated fatty acids of olive oil are part of a heart healthy diet.
Researchers from the Monell Chemical Senses Center in Galveston, Texas have found yet another piece of evidence that olive oil has positive effects on heart health. They have found a natural occurring chemical in extra-virgin olive oil which they named oleocanthal. This substance is a non-steroidal anti-inflammatory, a so-called COX inhibitor. The pharmacological action is the same as in the anti-inflammatory ibuprofen.

Dr. Gary Beauchamp (PhD) stated, “Some of the health-related effects of the Mediterranean diet may be due to the anti-COX activity of oleocanthal from premium olive oils”.

Dark Chocolate For Lower Blood Pressure

By | Heart Disease, High Blood Pressure, Nutrition

Chocolate, as long as it is consumed in moderation, can be good for you. The beneficial ingredients are the bioflavonoids, the same substances that are also found in fruit and vegetables.
Dr. Jeffrey Blumberg, PhD, at Tufts University in Boston reported about a study, where 20 adults with hypertension (high blood pressure) were asked to eat white chocolate or dark chocolate for 15 days. Blood pressure was reduced by an average of 12/9 mmHg with the dark chocolate. White chocolate had no effect, as blood pressures stayed the same. Dark chocolate also caused a dip in the LDL cholesterol and lowered insulin resistance.
The reason for the benefits lies in the bioflavonoids content: dark chocolate is rich in bioflavonoids, whereas milk chocolate contains little, and white chocolate the least of the three.
For all chocoholics this is not a ticket for a box of Belgian dark chocolates or an assortment of candy bars in one sitting.

Moderation is still the key, and you may consider consuming cocoa, perhaps as a Mexican chocolate drink without the fat and without the sugar.

Comfort Foods Make PMS More Uncomfortable

By | Mental Health, Nutrition, Prevention, Women’s Diseases

Premenstrual depression, moodiness, insomnia, abdominal cramps and headaches are some of the symptoms that create havoc for up to 40 % of menstruating women. Premenstrual Syndrome (or PMS for short) does not just mean a” cranky” few days for the women who suffer from it, but a host of unpleasant effects. Many experience bloating and breast tenderness, and they find that their daily functioning at work and in personal relationships is impaired. Food cravings are part of the picture, and often the so-called “comfort foods” are high on the list like ice cream, chocolate, cookies, or cake. Unfortunately these are not helpful at all, whereas other foods can be beneficial. The American College of Obstetricians and Gynecologists has published recommendations already in 2000 in which a diet of complex carbohydrates was recommended and supplementation of calcium, magnesium and vitamin E. Small meals that are rich in complex carbohydrates and that also contain protein and fat are useful to keep blood sugar levels stable. Even though some women crave sugar, candy, baked goods and pop, the rapid fluctuations in blood sugar only contribute to moodiness and irritability. Caffeine can also contribute to irritability, but by the same token, quitting coffee or tea abruptly will make many feel worse. A gradual decrease would be the gentler approach.
Alcohol intake is an especially bad idea, as it is a depressant and does nothing to lift the mood. People who have bloating or edema should avoid sodium.
Trials have shown what works to control PMS. More than 400 women were enrolled in a study group and were given 1,200 mg of chewable calcium carbonate daily. Those taking the supplement benefited from a 48% decrease of symptom severity. Within the Nurses’ Health Study II researchers followed up on a group of 1,057 women who got PMS and another group of 1,968 women who did not during 1991 and 2005. Women who consumed 400 IU of vitamin D a day had a lower relative risk of developing PMS. Consumption of calcium and vitamin D were measured by a food questionnaire. Calcium consumption of about four daily servings of fortified orange juice, skim-or low-fat milk or low-fat yogurt was inversely related to PMS.

The lead author of the study was Dr. Elizabeth Bertone-Johnson PhD, from the department of public health at the University of Massachusetts in Amherst. Her colleagues agree that vitamin D and calcium is beneficial to women of all ages, since these nutrients also reduce the risk of osteoporosis. Trials of vitamin B6 in doses of up to 100 mg daily seemed to help, as reported already in 2003 in a review by American Family Physician.

For the patient it means that small, regular meals are a good idea. So are complex carbohydrates, low-glycemic fruit like apples or berries and lots of vegetables. Consume low-fat milk or low-fat yogurt. Give the calcium supplements and the vitamin B6 a try. Minimize red meat, saturated and trans fats. Avoid salt, refined carbs, sugar, salt and alcohol. All of these aspects can make a significant contribution to a reduction of PMS symptoms as well as to health and wellness.

Diet Can Influence Acne

By | Nutrition, Skin Disorders

The old dermatological dogma that diet can play a role in the development of acne has been tossed back and forth. Some parties agree, others disagree. An old study by Fulton et al., which goes back to 1969, claims that patients who ate chocolate bars were compared to those who ate”pseudo-chocolate”, and no difference was found between the two groups. Both had the same amount of acne lesions. Critics of this poorly designed study however point out, that the” fake chocolate” contained just as much sugar and just as much trans fat as real chocolate. Trans fats are also known to contribute to inflammation, a condition that is present in acne.
In the meantime a 2002 study that was published in the Archives of Dermatology has taken a closer look at acne. Researchers took a look at islanders from Papua, New Guinea, and the Ache people of Paraguay. Both groups eat a non-Western low-glycemic diet. 1315 subjects were checked, and not a single case of acne was found. Even though this is merely an observational study, the results are impressive. Similar results have been reported in Okinawans, the South African Bantus, the Zulu and the Inuit. Even though these groups are continents apart, the common denominator is the same. Each group eats a non-Western diet. Another publication in 2005 in the Journal of the American Academy of Dermatology evaluated data from the Nurses Health Study II for a link between teenage acne and milk intake, and there was indeed a positive association. It may be that a milk allergy could be the explanation. Further evaluation is needed to pinpoint, which active compounds in milk are the culprits.

For now research points out that hyperinsulinemia, a metabolic condition stemming from an overload of highly refined and high glycemic carbohydrate foods, and its related hormonal cascade is the crucial link between the Western diet and acne. Other factors may emerge from investigating how milk consumption worsens acne.

Pancreatic Cancer And Processed Meats

By | Cancer, Nutrition

A large multi-ethnic study analyzed data from 190,545 men and women at the Cancer Research Center at the University of Hawaii. In an average follow-up time of 7 years there were 482 incidents of pancreatic cancer, and it became obvious that processed meats play a role in the increase of pancreatic cancer. After taking other risk factors into consideration like a positive family history, age, smoking and diabetes mellitus, those patients who consumed the largest amount of processed meats had a 67% increased risk for pancreatic cancer as opposed to those who had the lowest intake of these foods. A diet rich in red meats increased the risk by about 50%.

Poultry, fish, dairy products and egg intake showed no pancreatic cancer risk factor, nor did it matter how much fat, saturated fat or cholesterol was consumed over the 7 year observation period.

The lead investigator of the study, Dr. Ute Noethlings, observes that the risk increase is a consequence of the meat preparation with carcinogens. The main culprit would very likely be sodium nitrite, which is a preservative that also enhances the meat color.

For the consumer it means taking a critical look at processed meats before picking up sausages with your next shopping. Read the labels, avoid sodium nitrite. Your pancreas will thank you for it!

Lose Fat With Omega-3 Fish Oil And Exercise

By | Health, Men's Health, Nutrition, Prevention, Weight loss, Women’s Diseases

Omega-3 fish oil has been recognized to have significant benefits for healthy blood vessels and heart health. Ideally fish, which is rich in omega-3 fats, should be eaten several times per week, and salmon, mackerel or sardines are excellent choices. Some individuals are not fond of these choices and do not get enough of omega-3 fats. There is still the alternative to take fish oil. Most people would cringe at the idea of swallowing a spoonful of cod liver oil, but fish oil, which can be taken encased in a gelatin capsule is no longer a “yuck” experience.
It is certainly worthwhile to take a closer look at omega-3 fish oil, as new research from Adelaide, Australia has come into the forefront, associating fish oil with health benefits. Dr. Peter Howe, PhD from the South Australian University’s School of Health Sciences supervised research on patients with metabolic syndrome. They were overweight, had high blood pressure, a high insulin level and high blood fat or triglyceride levels. The patients participated in a 12-week program, which not only included moderate aerobic exercise three times per week, but also the intake of fish oil or sunflower oil. A control group received sunflower oil combined with exercise. The difference was quite significant: those on a regimen of exercise and fish oil supplementation lost more body fat mass than those who were using sunflower oil and adhered to an exercise program.
Exercise alone and fish oil alone did not produce these effects. It was the combination that made the difference! The researchers state that omega-3 fatty acids cause a switch to enzymes that burn fat, but exercise is the driver, which increases the metabolic rate, so fat loss becomes possible. It was also found that the winning combination of fish oil and exercise promoted a decrease in blood pressure and triglyceride levels.

Dr. Howe noted that not only did it reduce body fat (weight loss mostly noticeable in the abdominal area), but also it was beneficial to the patients’ general health. It is the protective effect of omega-3 fish oil on blood vessels, which is making them more elastic and more efficient in transporting nutrients to the muscles.

Red Bull Not A Natural Health Drink

By | Nutrition

Some people like the caffeine fix in the form of coffee, cola drinks or chocolate. The kick of 36 mg of caffeine in one can of cola is enough of a wake up call and can interfere with falling asleep at night. In the meantime however, some soft drinks appeal to the crowd that thinks that more must be better. One of the concoctions, Red Bull, which came originally from Austria, has managed to be approved by Health Canada as a “natural health product”.

There are a few strings attached: the label must carry a warning that the drink is not recommended for children and breast-feeding women. The drink should not be mixed with alcohol, and no more than 500 ml (two cans) should be consumed per day. The European Commission on Food Safety had closely scrutinized it, and the product is in fact banned in France, Denmark, and Norway, as the authorities are not sure about the long-term effect of the ingredients, namely taurine, caffeine and glucuronolactone.

The problem remains that any kid can have access to Red Bull at the corner store. No one is watching how much is consumed. These drinks have become hot seller-last year alone 80,000 L of “energy drinks” were sold in Canada alone. Red Bull packs a significant 80 mg of caffeine, “Guru” comes in with 125 mg of caffeine, and it is even sold in school cafeterias in Montreal.

Red Bull Not A Natural Health Drink

Red Bull Not A Natural Health Drink

A sports nutritionist observed also, that it has become a popular practice among certain athletes to down three or full cans of Red Bull and in addition combine this whopping dose with a product” Hot Rox”, which delivers another jolt of 1000 mg caffeine. Exaggerated adrenaline rush can be the perfect recipe for injury, insomnia and poor recovery.
The breweries seem to want a market slice too, as Labatt’s new “Shok” sports more alcohol (6.9%) and 60 mg of caffeine in addition. Molson”s “Kick” delivers 55 mg caffeine and 5% alcohol.
Doctors should be on the watch for caffeine overdoses and also the resulting withdrawal symptoms. Transient behavior changes, irritability, nervousness and anxiety are on the list for the first, lack of energy and inability to concentrate are the effects of withdrawal. Reaching for stimulants also give a false sense of energy is no substitute for energy from real food. And last not least the label saying “all natural” does not guarantee safety.

Burgers, Fries and High Healthcare Costs

By | Cancer, Health, Heart Disease, Nutrition, Obesity, Stroke

“Everything in moderation” and “A little bit cannot harm” are the deceptively soothing terms that can lull consumers into the belief, that fast foods cannot be so bad after all. A study, called the” Coronary Artery Risk Development in Young Adults” however gives us the facts, that paint a more realistic picture: the “little bit” actually has fairly serious consequences!
In this U.S. study a wide cross section of young adults were followed in four U.S centers: Birmingham, Ala., Chicago, Minneapolis and Oakland Calif. 3031 people in the age of 18 to 30 years were recruited in 1985 and followed until 2001.

Lifestyle habits, such as smoking, watching TV and intake of other foods were recorded, and insulin resistance was measured. In addition there were detailed studies of weight, height, waist size and other body measurements. Some interesting facts emerged: women ate fast foods less frequently than men. Fast food intake was associated with lower education, more TV watching, lower physical activity, high intake of trans fats and alcohol intake. In short: fast foods and other unhealthy lifestyle choices were correlated.

Dr. Mark Pereira, PhD of the University of Minnesota School of Public Health, who is one of the authors of the study, points out that it is extremely difficult to eat in a healthy way in a fast foods restaurant. The menus still include foods high in fat, sugar and calories and low in fiber and nutrients. Dr. Arne Astrup from the RVA University in Copenhagen found the same issues: besides the fact that serving sizes have increased two to five fold over the past fifty years, the energy density is twice as high in fast foods as compared to food in healthy diets. Dr. Astrup also points out in his publication, that humans have only a weak innate ability to recognize foods with high energy density and then down-regulate the amount eaten to meet and not exceed energy requirements.

Burgers, Fries and High Healthcare Costs

Burgers, Fries and High Healthcare Costs

If a person ate more than 2 fast food meals per week, which would be a modest increase of the control group that ate less than 1 fast food meal per week, the 2 meals per week group was about 5 kg heavier after 15 years, as opposed to 11 kg in the control group. The insulin resistance increased by an alarming 230 %. This finding is of significance, as insulin resistance (=metabolic syndrome) promotes the occurrence of cardiovascular disease and cancer, especially breast and colorectal cancers. The data are showing that even a modest increase has a unique effect in increasing the risks for these disease patterns, and the message is, that health care costs will only come down, if the root cause of disease is attacked at the societal and lifestyle level.

Liver Cirrhosis Threatens Overweight Children

By | Gastrointestinal Disease, Nutrition, Obesity

Generally the condition of liver cirrhosis has been associated with excessive alcohol intake, and the victims have been adults.
A similar condition is the fatty infiltration of the liver, where the function becomes impaired through the growth of fatty tissue, which replaces healthy tissue. In its worst form this non-alcoholic fatty liver disease can advance to cirrhosis and end-stage liver disease. So far this devastating course of illness has been seen in adults, but it is not confined to the adult population. The most important risk factor for this disease is obesity, and with one in three children in Canada now overweight, the previous adult-only disease is now affecting kids. Non-alcoholic fatty liver disease is now the most common cause of abnormal liver tests.

Dr. Ariel Feldstein, a pediatric gastroenterologist from the Mayo Clinic in Rochester reports that the average age of children with these symptoms is about 12, which is an alarmingly low age for this picture. There is also a warning, that children do not even have to sport a sky-high body-mass index (BMI). The risk is already significant with a high BMI.The most direct approach to prevent type 2 diabetes and fatty-liver disease in children has to start within the family. Instead of singling out the child it is important to work together as a family to become healthier. The terms”fat”, “chubby”, “exercise” and “diet” are less conducive to improvement than “physical activity” and “better nutrition”. Consistent minor changes are also more important than crash diets that come and go.

Liver Cirrhosis Threatens Overweight Children

Liver Cirrhosis Threatens Overweight Children

Eating more vegetables and fruit, not eating and snacking mindlessly in front of the TV, eating together as a family and preparing healthy snacks instead of tossing a cookie bar or a bag of chips into the lunch bag are all ways that benefit the entire family.
A study from Dr. Robert Berkowitz at the Children’s’ Hospital of Philadelphia affirms even more, that prevention has to start with the parents: children born to overweight mothers have a higher risk of following the pattern of having a high body mass index than those whose parents were normal weight.

Asian Diet To Manage Menopause

By | Nutrition, Weight loss, Women’s Diseases

Hormone Replacement Therapy (HRT) has not only benefits. The potential side effects have become evident, and as a result, doctors have cautioned their patients, that HRT may not be the answer for every menopausal woman. However, lately natural hormone replacement therapy has become popular as an alternative. According to statistics only 20% of Asian women are plagued by hot flashes during menopause as compared to 80% of Westerners. A lifestyle intervention trial from Australia taught 120 women to adapt Japanese diet and lifestyle habits. The participants of the trial also started an exercise program for women, drank lots of water, increased calcium intake and increased the intake of plant-estrogens. Researchers had chosen this model, as Japanese women average five more years of healthy living than their sisters in the West. The spotlight of the research continues to focus on plant-based estrogens. Isoflavone precursors are found in soy (which is widely consumed in Asia), but it is also present in fruits, vegetables, legumes and seeds such as flax. We do not know too much about the long-term effect of manufactured or isolated soy products, and so it is best to stay with the natural soy foods such as edamame (soy beans), tofu, tempeh and miso. Beside soy foods, lots of vegetables, beans and fruit are beneficial, and ground flax seed has also shown to decrease menopausal symptoms. Research in Chinese women has shown a modest association between post-menopausal soy intake and increased bone density.

Asian Diet To Manage Menopause

Compared to this, the “typical” North American diet isn’t an accessory to good health; being high in white flour, sugar, trans fat and providing saturated fat of meat and dairy products this is also bad news for menopause. In addition there is a correlation between an increased body mass index and one to five alcoholic drinks per week with increased hot flashes in peri-menopausal women. Research from Simmons College at the Harvard School of Public Health has shown that Western food habits of red meat and processed meats (hot dogs, bacon) put especially women’s health at risk.

Some experts say that the health of Asian women is more robust due to their life-long soy intake, in which case it would make sense to not even wait for all the dreaded symptoms of menopause to appear, but make way for healthy diet choices early. Soy products have become immensely popular and are readily available in today’s market, and so it will be interesting to see if the next generation of women has an easier time going through menopause.
