Dietary Minerals 2




Biological functions and health benefits

Minerals by themselves are inactive chemical elements, like the iron in a pan or calcium in a rock. But in the body, mineral nutrients are required to build tissues. They are also important for muscle contractions, nerve reactions, and blood clotting. Minerals help maintain acid-base balance, to keep the body pH neutral. Minerals help regulate body processes, such as in enzyme systems. Minerals function in nerve impulse transmission and muscle contraction. Minerals help release energy from food. For instance, calcium and phosphorous are important in bone structure and growth; potassium and sodium for electrolyte balance; and iron for oxygen transport. Some enzymes need metal ions obtained from minerals to aid chemical reactions in the body. Calcium, the most abundant mineral in the human body, has several important functions. he body uses this iron to carry oxygen to its cells. Chromium helps moves blood sugar (glucose) from the bloodstream into the cells to be used as energy and turn fats, carbohydrates, and proteins into energy. Copper is needed to help body use iron. Humans require iodine for proper physical and mental development. Magnesium is used by the body to help maintain muscles, nerves, and bones. Manganese is required to manufacture enzymes necessary for the metabolism of proteins and fat. Molybdenum functions as a cofactor for a number of enzymes that catalyze important chemical transformations in the global carbon, nitrogen, and sulfur cycles. Phosphorus promotes and stimulates early growth and blooming and root growth. Potassium works with sodium to maintain the body's water balance. Selenium is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. Zinc functions as an antioxidant and is involved in many critical biochemical reactions.
