Multi-Minerals MULTI-BENEFITS

Better Nutrition, Nov, 1998 by James F. Scheer

The Balches warn that excessive iron intake can also cause problems, saying, "Too much iron in the tissues and organs leads to the production of free radicals.... High levels of iron have also been found in association with heart disease and cancer."

Selenium. Research by biochemist Gerhard Schrauzer, Ph.D., of the University of California at San Diego, established selenium as a prime contributor in defending us against various cancers: breast, colon, ovary, pancreas, and prostate. This trace mineral works closely with vitamin E as a superantioxidant to protect cell membranes. It also guards us from toxic heavy metals, stimulates the immune system, helps lower the risk of heart attack, and seems to benefit some arthritis sufferers.

The most recent issue of the Nutrition Research Newsletter discusses a study conducted by the University of Arizona's Arizona Cancer Center involving 1,312 patients and their daily intake of 200 mcg of selenium.

Larry Clark, Ph.D., M.P.H., led the study. Clark, and associates, found that selenium B in -- comparison with a placebo -- reduced the number of new cases of lung cancer by 48 percent, colorectal cancer by 58 percent, and prostate cancer by 63 percent.

Now pursuing a more in-depth study of selenium as a cancer preventive, Clark called these findings "statistically significant." However, with scientific caution, he hesitated to recommend that people take specific amounts of selenium until more data are available to set a firm recommended daily allowance.

Nevertheless, "if people have a cancer concern, such as a pre-malignant lesion, they might want to take selenium to put their mind at ease," he stated. Selenium can be derived from seafood, whole grains, broccoli, cabbage, corn, and mushrooms. Only tiny amounts are required in the daily diet: 100-200 mcg.

Zinc. It is often called "the sexy mineral," because it contributes to the development and function of male sex organs (especially the prostate), to fertility (including hormone metabolism, sperm formation, and sperm motility), and growth and body development. Zinc is also known for revving up the immune system, speeding wound healing, and, as an antioxidant, protecting cells against damage from free radicals. Recent research has indicated that zinc gluconate lozenges can help ease colds and flu, too. It also keeps our senses of smell and taste normal.

A little-known function of zinc is revealed in the new book, The Natural Pharmacy, edited by Skye Lininger, D.C., and written by five prominent nutrition-oriented doctors, who say, "People with insulin-dependent diabetes mellitus (IDDM) tend to be zinc-deficient, which may impair immune function. Zinc supplements have lowered blood sugar levels in people with IDDM.... Many doctors of natural medicine recommend that people with NIDDM [non-insulin-dependent diabetes mellitus] supplement with moderate amounts of zinc: 15-25 mg per day as a way to correct for the deficit."

So, as you can see, "Take your minerals" is very good advice, indeed.
