The Seven Key Minerals Our Bodies Need
October 25th 2007 11:48
The typical American diet, rich in calories and fat, is often poor in minerals, the inorganic elements our bodies need. According to dietitians, minerals perform an amazing number of functions, helping to build bones, regulate metabolism, fire nerves, and maintain overall health. But a number of studies reveal that many women do not get enough calcium and iron, and most people get too little magnesium and zinc. The same studies likewise confirm that most people also consume too much sodium and not enough potassium (together, these electrolytes help maintain fluid balance and regulate muscle and heart function).
We know that in almost anything, too much can be as harmful as too little. For instance, if you are diagnosed with iron deficiency, your doctor may recommend an iron supplement; however, if you take one when you don't need one, you may increase your risk of heart disease and cancer. Some minerals, such as selenium, are toxic in large amounts. And too much of certain minerals can affect levels of another. One study showed that just 18 to 25 milligrams (mg) of zinc - a tad over the recommended 9 mg for women and 12 mg for men - may lower blood levels of copper, another essential mineral. Another study of postmenopausal women found that increasing daily calcium intake from 750 mg to 1,400 mg reduced the absorption of zinc. Experts say that the solution is not to skip calcium supplements if you need them but to add a multivitamin/mineral supplement. Choose one with no more than 100 percent of the recommended nutrient intake[ Click here to read more ]
