Carbohydrates • Your body has the easiest time digesting carbohydrates like sugar and starch.Carbohydrates are broken down into individualglucose, fructose or galactose units. Glucose isyour bodys favorite form of energy. If you dontget enough carbohydrates, your body can make glucose from protein or fat -- and if you get toomany carbohydrates, your body is very good at storing them as fat.
Protein• Good nutrition provides raw materials. Protein in the foods you eat is broken down into individual amino acids. Your body uses the amino acids to build and repair the various parts of your body. Your muscles contain lots of protein, and you need to replenish that protein through your diet. Your body also needs protein for components of your immune system, hormones, nervous system, and organs.
Fats• Your body also needs fats to be healthy. Membranes that contain fats surround all the cells of your body. Your brain has fatty acids, and fats are also needed to signal hormones.
The vitamins and minerals you getfrom your diet are just as importantas carbohydrates, protein and fats,even though you only need them in small amounts. They usually function as co-enzymes, which means they help some of yourbodys chemical reactions happen a lot faster.
