Is a fat-like waxy substance found in animal products and the liver also makes it Blood carries cholesterol by lipoproteins (HDL and LDL) HDL = “healthy” and LDL = “Bad” INCREASE HDL THROUGH PHYSICAL ACTIVITY!!!! Too much LDL = deposits of cholesterol built up on the arteries = narrowing arteries = slow or block blood flow to the heart CHOLESTEROL

The building block of the body NOT the main source of energy Necessary for growth, maintenance and repair of all body tissues Immune System) Also help maintain normal balance of body fluids and are necessary to make enzymes, hormones and antibodies (Immune System) 20 amino acids make up protein but 9 amino acids you must consume daily Often “overrated” (overeaten) Often “overrated” (overeaten) Overload Principle) - ONLY work builds muscles (Overload Principle) PROTEINS

Insoluble- *allows food residues to pass through intestinal tract more quickly- limiting exposure and absorption time of toxic substances within waste. Soluble- *helps the body excrete fats and paces the absorption of cholesterol which helps prevent dramatic shifts in blood sugar levels. FIBER
