Extra glucose is stored as gycogen
Complex Carbs have fiber
Fiber – can’t be digested
cleans out the digestive system
reduces risks of cardiovascular disease and colon cancer

6. The role of proteins Amino Acids (AA)
Building blocks for proteins
20 Amino Acids
Essential AA

Are found in foods
Body can make from food combinations

7. Types of Proteins Complete Proteins Incomplete Proteins Animal sources
Contain all 9 essential AA’s
Meat, eggs, dairy, soy

3 types 9 calories/gram Stored energy
UNSATURATED FATS room temp)
Vegetable Oils
Nuts & Seeds
SATURATED FATS room tem)
Animal products
Meat & Dairy
Coconut Oil
TRANS FATS
Hydrogenation cause vegetable oil to become more saturated.
Margarine, snack foods, baked goods

9. The Role of Fats Brain development Controls inflammation
Concentrated and stored energy
Absorb & transport fat-soluble vit. (A, D, E, K)
Brain development

by the body.
The body can’t make/no energy
Strong bones/teeth
Electrolytes for fluid balance
Examples) Sodium, calcium, phosphorous, iron, zinc

13. Water Soluble Vitamins:
Stored in water; extra leaves body in urine C
Fights infection and heals wounds
Healthy bones, teeth, gums, blood vessels
Folic Acid
Reduces risk of birth defects
Forms new cells
B complex
Helps body use energy
Supports immune & nervous system
Helps red blood cells

14. Fat Soluble Vitamins: Stored in body fat; can reach toxic levels A
Night vision
White blood cells and cell growth D
Helps body use calcium and phosporus
Maintain strong bones E
Prevent cell damage and repair tissues
Aids in blood flow K
Essential for blood clotting
Helps with bone formation

15. a condition in which bones become fragile and break easily.
Osteoporosis:
a condition in which bones become fragile and break easily.
Women and fair skin people more at-risk
Weight bearing activities reduce risk
Calcium is important in prevention

16. 6 Types of Nutrients 3 body functions (continued)
WATER = the most ESSENTIAL nutrient
Helps digestive sysyem

Cooling the body through perspiration(sweat)
Cushioning the eyes, brain, and spinal cord
Teen Males = 13 cups of water per day.
