Document Summary
Food: made of animals and plants. Nutrients needed in the body in large amounts. Main function is to give us energy. Body breaks them down and absorbs through the gi tract.

Food energy is measured in k(cid:272)als (cid:271)ut it"s ofte(cid:374) just (cid:272)alled (cid:272)alories. Vitamins: organic molecules out body needs in order to function. Inorganic molecules (from the periodic table) out body needs in order to function: needed in small amounts, e. g. calcium, magnesium, iron. Do(cid:374)"t pro(cid:448)ide us (cid:449)ith e(cid:374)ergy, (cid:271)ut (cid:449)e (cid:374)eed to eat the(cid:373) so our (cid:271)ody (cid:272)a(cid:374) fu(cid:374)(cid:272)tio(cid:374: antioxidents. Vitamin a and c: control nerve and muscle action, make and maintain tissues like bones and blood. Calcium: bone development: regulate energy metabolism. B12: helps our bodies function/increase rate of reaction. Do(cid:374)"t feel as tired throughout the day.
