Get Your Vitamins From Food, Not Pills

One in three women and one in four men in the United States take vitamin pills. If you are among them, you may be doing more harm than good. In a wake up call to the multibillion dollar vitamin pill industry, a review of 67 randomized trials of vitamin pill effects on life and health has found that taking vitamin pills may shorten life (Cochrane Database of Systematic Reviews, Issue 1, 2008). Other studies have shown that taking vitamin pills may increase risk for cancers and heart attacks.This review of 232,000 adults showed that those taking beta-carotene, vitamin A, C, and E and selenium gained no benefit over those who took placebos or no pills. "The findings show that, if anything, people in trial groups given beta-carotene, vitamin A...

Will Organic Foods Make You More Healthy?

According to a report published by The Organic Center's State of Science Reviews(March 2008), organic foods are more nutritious than those grown conventionally. But since the average North American eats far more food than is necessary, it is doubtful that adding more nutrients to the diet will have much effect on health. A review of 97 scientific papers shows that organic food has higher levels of eight of 11 nutrients studied, including greater concentrations of polyphenols and antioxidants. However, we don't know how much of these nutrients the body requires. With 35 percent of the population becoming diabetic, 91 percent developing high blood pressure, 78 percent having high cholesterol levels, and 40 percent dying of heart attacks and...

How Exercise Prevents Diabetes AND Preserves Your Brain

Several studies show that vigorous exercise can help to prevent and to treat diabetes. A recent study from the University of Missouri in Columbia helps to explain why (American Journal of Physiology - Regulatory, Integrative and Comparative Physiology, April 2008).The vast majority of people who have diabetes do not lack insulin. Their disease is caused by an inability to respond to insulin. Since their cells do not respond to insulin, blood sugar levels rise and damage their cells. By studying blood flowing to and from the hind legs of obese rats, researchers found that acute muscle contractions markedly increased the passage of sugar into skeletal muscles, and markedly increased the flow of electrons in mitochondria.Muscle cells have anywhere...

Vitamin C Won't Help You Exercise Longer

Some exercisers take vitamin C because they think that it will help them recover faster and therefore become better athletes. However, a study from the University of Valencia in Spain shows that vitamin C pills can make an athlete tire earlier during long-term exercise. (Journal reference)Every muscle cell has hundreds, and even thousands, of small inclusions called mitochondria that turn food into the force that drives muscles. They do this by shuffling electrons to produce energy. After the electrons are moved, they can end up stuck on oxygen molecules to produce poisons called oxidants that make muscles burn, and feel sore and tired. The human body produces antioxidants that help protect a person from cell damage from these oxidants. Large...

Microwaving Does Not Harm Foods

A report from the nutrition department of Cornell University should convince you that microwaving food does not destroy its nutritional value. Dr. Gertrude Armbruster and her colleagues showed that fruits and vegetables lost the least vitamin C when microwaved, compared to other cooking methods. Vitamin C is a good indicator of the amount of nutrients lost because it is both water soluble and sensitive to heat (Newsweek, March 14, 2008).Microwave ovens use electromagnetic waves that vibrate water molecules inside food to produce heat. Most nutrients in food are not destroyed by microwaving because they are not in the watery layer. An earlier study from Spain, widely reported in the news media, claimed that microwaving broccoli destroyed all...

Vitamin D and Muslce Pain - Special Report

Over the last few years I have reported on numerous studies linking vitamin D deficiency with various diseases: diabetes, heart attacks, at least 30 types of cancer, and autoimmune disease such as lupus and rheumatoid arthritis (a list of these reports appears below).This winter I have had a series of baffling exercise- associated muscle injuries. My blood levels of vitamin D have been extremely low, even though I spend a lot of time outside riding my bike. I reviewed my diaries and found that wintertime injuries have been a lifelong pattern for me. I have not been able to find any strong evidence that lack of vitamin D causes muscle injuries. However, it is associated with muscle weakness, falling in older people, bone deformities and fractures.People...

Branched Chain Amino Acids

A study from Sacred Heart University in Fairfield, Connecticut showed that taking branched chain amino acids decreased the amount of muscle damage from exercise in untrained volunteers. Branched chain amino acids are protein building blocks that can be converted easily to sugar by your body. A likely explanation for the advantage shown in this study is that muscles become damaged when they run out of their stored sugar and start to burn protein in the muscles themselves for energy. Journal referenceHowever, it makes no sense to spend a lot of money on these expensive protein supplements. You will get the same benefit from any food that contains protein. Eat some cheese, seafood, peanut butter, chicken, nuts or any other convenient source of...

Eggs Do Not Raise Cholesterol

For more than 50 years eggs have been called unhealthful because they are among the foods that contain the highest levels of cholesterol. However, in recent years eggs have been rehabilitated. This month, a team of researchers at Mahidol University in Bangkok showed that adding an egg a day to the diets of healthy people in Thailand raised the good HDL cholesterol that prevents heart attacks. It did not affect the bad LDL cholesterol or triglycerides (Journal of the Medical Association of Thailand, March 2008). Adding as many as three eggs per day to your diet will not raise cholesterol. More than 80 percent of the cholesterol in your body is manufactured by your liver, and less than 20 percent comes from the food you eat. When you eat more...

Men Underestimate their Waist Sizes

Men report that their waist circumferences are an average of 3.1 inches slimmer than they actually are, according to a study from University of Leicester in England. They can die from this vanity. Storing fat in your belly is a major risk factor for diabetes that causes blindness, deafness, heart attacks, strokes, amputations and kidney disease.Almost all men who have more than three inches of fat underneath the skin over their bellies are either diabetic or pre- diabetic. More than 80 percent of people diagnosed with type 2 diabetes are overweight at the time of their diagnosis. Since insulin causes fat to be deposited primarily in the belly, storing more than three inches of fat underneath your skin is a sign of high insulin levels. Almost...
