Minerals

Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium. Recommended Dietary Allowance (RDA) is the amount of a nutrient you should get each day. There are different RDAs based on age, gender, and whether a woman is pregnant or breastfeeding.
