Functions of Minerals
Minerals are essential nutrients that are required in small amounts by the body to perform various functions. They are inorganic substances that cannot be synthesized by the body and must be obtained through the diet. There are two types of minerals: macrominerals and trace minerals. Macrominerals are required in larger amounts, while trace minerals are needed in smaller amounts.
Body Functions
Minerals play a vital role in maintaining various body functions. They are required for the proper functioning of enzymes, hormones, and other biochemical reactions in the body. Minerals such as sodium, potassium, and chloride are electrolytes that help regulate fluid balance in the body. Magnesium is involved in energy production and muscle function.
Bone Health
Minerals are essential for maintaining healthy bones. Calcium, phosphorus, and magnesium are the major minerals that make up bone tissue. They provide strength and structure to the bones and help prevent osteoporosis, a condition characterized by weak and brittle bones. Vitamin D is also important for bone health as it helps the body absorb calcium.
Disease Prevention
Minerals are also important for disease prevention. Zinc and selenium are antioxidants that help protect the body against damage from free radicals. Iron is important for the production of red blood cells and the prevention of anemia. Copper is involved in the production of collagen, a protein that is important for skin health.
