 Carbohydrates- starches and sugars present in foods Simple- fructose, lactose, maltose Complex- starches: whole grains, legumes, potatoes Main source of energy is role Carbohydrates turn into glucose once broken down Fiber is indigestible complex carbohydrate, helps move waste out of body

 Proteins- help build and maintain body cells and tissues 9 out of the 20 that the body can not make are called essential amino acids Complete proteins have all 9 ex-fish, meat, eggs, milk Incomplete proteins have one or more ex-beans, peas, nuts Role is to build new cells and tissues

 Fats- called a lipid-fatty substance that does not dissolve in water Saturated fatty acid-solid at room temperature, ex- animal fats, tropical oils such as coconut oil, heart disease associated with large amounts of saturated fatty acids Unsaturated fatty acids- liquid at room temperature, ex-corn, olive, canola oil Eat less fat to decrease cardiovascular disease Cholesterol- is waxy like substance in blood and excess is stored in arteries, affected by heredity, age and weight

 Vitamins- compounds that help regulate many vital body processes, including digestion, absorption, and metabolism  2 types fat and water soluble  Fat- stored in the fat cells, can be toxic if too many inside the body and water must be replenished each day  Minerals- substances that the body cannot manufacture but that are needed for forming healthy bones and teeth and for regulating many vital body processes

 Water is the most vital one to every body function  Water is the greatest percentage in the body of all other things  We need to drink plenty to stay hydrated and to prevent an electrolyte imbalance  Fatigue is reliable indicator of dehydration, muscle cramps and dizziness occur due to dehydration also  Processes food contain large amounts of salt

 From stomach go to small intestines which is where nutrients are absorbed through the inner wall  Then the large intestine absorbs the rest and then eliminates waste  Bile is produced by the liver and helps with digestion in the small intestine  Heart burn results from acid reflux coming out of the stomach back into the esophagus

 Waste products of the digestion process also include the undigested foods  If the body can not digest the sugars in milk it is called lactose intolerance  Dehydration causes the pituitary gland to secrete hormones to say our body’s need nutrients
