How are minerals classified, and what common characteristics do major minerals share?
Essential minerals are classified by how much you need as major or trace minerals. Major minerals are needed in amounts >100 mg per day and are found in seafood, meat, and dairy products (some are also obtained from fruit, vegetables, and legumes). Absorption of some minerals is not regulated and decreases with age. Bioavailability of others is influenced by genetics, nutritional status, and interactions with other components in food. The primary site of absorption is the small intestine. Major minerals circulate directly from the GI tract to the liver and are transported via the blood. Blood levels are regulated by the small intestine at the time of absorption and by the kidneys at the time of excretion.
