WARNING: Too Many Supplements May Up Cancer Risk
About three years ago I went to Hippocrates Health Institute. At HHI the lifestyle is 100% raw food and taking care of one's total dietary (includes supplements) health as well as total lifestyle changes, e.g. water, exercise, sunlight, sleep, etc. During the three week program, all participants were encouraged to sign a self-contract that toothpaste, shampoo, and cosmetics would even be the pure and natural kind. People, if they weren't on serious prescriptions, were even encouraged under doctor's guidance not to take their meds and especially to lay off their "health-supporting" supplements. Wow, Brian Clement, the program director and author of several books including Supplements Exposed, told about some people having such serious withdrawals from their supplements that they would have tremors and other disturbing side-effects. Unlike what marketing strategies suggest, these "healthy supplements" really aren't all that healthy!
A large-scale study has shown that over-supplementation could be very bad for our health.
Could it be possible that too many vitamins and minerals can bring about various forms of cancer? Yes, according to a large-scale study delivered during the American Association for Cancer Research (AACR) Annual Meeting 2015.
The research presented at this conference dates back 20 years, when scientists discovered that a diet rich in fruits and vegetables was shown to keep cancer at bay. Then study experts shifted their focus to over-the-counter supplements, assuming that consuming extra vitamins and minerals would also produce anti-cancer benefits.
First came the testing on animals and the results were encouraging. Scientists then studied thousands of patients—over 300,000—who were given either dietary supplements or a placebo over a 10-year period.
And their findings were alarming...
“We show that not only is supplementing your diet with vitamins that are found in a healthy diet unlikely to decrease your risk of developing cancer, but in some cases, taking more than the recommended daily allowance of these supplements can increase cancer risk,” lead investigator Tim Byers, MD, MPH from the University of Colorado Cancer Center tells Yahoo Health. “More specifically, taking more than the recommended daily allowance of folic acid, Vitamin E and beta-carotene were all shown to increase cancer risk.”
One trial showed that taking more than the required amounts of beta-carotene — which is known for its ability to improve immunity and enhance vision — in supplement form increased the risk for developing both lung cancer and heart disease by 20 percent. Men who took an excess of vitamin E were at a higher risk of being diagnosed with prostate cancer. And while folic acid — a B vitamin — was considered a possible remedy for reducing the number of polyps in the colon, it increased the number in another trial.
"There really is no strong hypothesis explaining why these dietary supplements increase cancer risk," states Byers. "It may have to do with the body's overall nutrient balance, in this case 'imbalance', or it may have to do with specific effects of overall consumption of specific supplements."
So should we avoid the vitamin aisle altogether? "Unfortunately, few Americans eat a well-balanced diet and hope to make up for this by taking dietary supplements," says Byers. "My recommendation is to get your nutrients from a healthy diet. If you take vitamins or other dietary supplements, choose products that stay within the recommended daily allowance."
My personal take on this article is every person who consumes vitamins should be aware that in almost all cases the vitamins and supplements are manufactured by pharmaceutical companies and the substance of the "supplementation" is actually chemical, which is not food and should not be treated as food or food supplements. For more on this read "Supplements Exposed" by Brian Clement, and there are many more books on the market exposing the fallacy that supplementation is beneficial for "supplementing" our poor diet choices.
