CARBOHYDRATES stores and transports energy foods that give energy are : either starches or sugars broken down into simple sugars sugars absorbed into the bloodstream sugar level rises, pancreas releases hormone, insulin needed to move sugar from blood to cells sugar used as a source of energy

PROTEIN builds cardiac muscle makes part of red blood cells that carries oxygen two types complete –has all 9 main amino acids »found in meat and milk incomplete »found in most vegetables: broccoli- carrots -tomatoes -peas

PROTEIN sources of protein are : -meat -fish -egg -dairy products kids require 0.5 g of protein for pound they weigh muscles, organs + immunes system made of protein broken protein into basic units = amino acids quickly digested many different amino acids in protein 22 are important to human health.
