CARBOHYDRATES

Complex Carbohydrates-

stored in the body to

be used at a later date

for energy. “glycogen”

ex. pasta,rice,bread

Simple Carbohydrates-

used by the body

immediately for quick

energy. “glucose”

ex. cakes,candy,fruit

FIBER

Soluble Fiber:•Functions: may help lower blood cholesterol by inhibiting digestion of fat and cholesterol; helps control blood sugar in people with diabetes.Insoluble Fiber:•Functions: helps prevent constipation, hemorrhoids, and diverticulosis

FATS

TWO TYPES OF FAT:

saturated fat-solid at room temperature

unsaturated fat-liquid at room temperature

FUNCTION OF FAT:

1. Insulation for the body (temperature)

2. Protection for internal organs, nerves, and

tissues

3. Forms part of cell structure

4. Energy for the body

FAT CELLS• Cholesterol is a waxy,

fatlike substances that is found in the cells of all animals.

• High cholesterol is associated with heart disease.

CHOLESTEROL

PROTEINSAMINO ACIDS

• Building blocks• 20-28 different amino

acids.• Essential (not produced by the

body) and Nonessential (produced bythe body)

• Essential amino acids: animal sources (complete)plant sources (incomplete)

Protein should account for 10% to 20% of the calories consumed eachday. Protein is essential to the structure of red blood cells, for theproper functioning of antibodies resisting infection, for the regulation ofenzymes and hormones, for muscle growth and repair, and for therepair of body tissue. Proteins can also be a source of energy.

VITAMINS

WATER-SOLUBLE: FAT-SOLUBLE:C, ALL Bs: B1,B2,B6,B12, NIACIN,FOLIC ACID, A, E, D, and KBIOTIN, and PANTHOTHENIC ACID

Water soluble travel through bloodstream being used immediately by the body.Any unused vitamins are urinated out of the body. Fat soluble are stored in the fattissues and liver for later use.

FUNCTIONS: collagen for cells, cell growth, stronger teeth, gums, bones, blood vessels, helps absorption rate for iron, resistance to infection, aids central nervous system, converts sugar into fuel, healthy hair, vision, protects red blood cells, helps blood to clot, proper digestion, kidney function, and helps the metabolism rate.

MINERALS

• Calcium-stronger bones & teeth.

• Iron-formation of hemoglobin to transport

oxygen to lungs.• Potassium-muscles and

nervous system work properly.

• Zinc-maintains immunesystem & cell growth.

WATERWATER IS NEEDED TO MAINTAIN A HEALTHYDIET. THE HUMAN BODY IS ABOUT 70% WATER.

BRAIN-75-85% water & parts a vital role indehydration. It controls water intake throughaltering thirst and varying the water excretion from your kidneys. A loss of 10% or more of body weight due to fluid loss can be life threatening.

MOUTH-Thirst is a good indicator of hydration. By the time you feel thirst you have lose 2 to 5 cups of water. The production of saliva is vital to good oral hygiene.

LUNGS- Your body loses water every time you breath. Every day you lose the equivalent of a can of drink just by breathing.

HEART- Water is needed to continue the mechanical function of the heart. Cells need to stay hydrated so the heart can stimulate electrical impulse which allow the heart muscles to contract. Drinking five or more glasses a day can help reduce the risk of coronary heart disease.

KIDNEYS-Control the amount of water, filters your blood, excretes waste in your urine, and leaves nutrients in your bloodstream.

BLOOD-75% water and is vital for transportation of nutrients.
