◉ Phosphorus function
Answer: Formation of bones and teeth
◉ Minerals are essential nutrients needed in relatively small
amounts to enable your body to function properly. All minerals are
inorganic elements. The body's absorption of minerals from foods
varies, depending on their bioavailability. The seven major minerals
are needed in amounts greater than 100 milligrams per day, and the
nine trace minerals are needed in amounts less than 20 milligrams
per day. Several minerals, particularly the trace minerals, can be
toxic if consumed in high amounts.
Answer:
◉ Calcium is the most abundant mineral in the body
