Proteins
Carbohydrates
Fats (Lipids)
Water
Fiber
Vitamins
Minerals

5. Calories Protein: 1 gram = 4 calories
Carbohydrate: 1 gram = 4 calories
Fat: 1 gram = 9 calories

6. Proteins: 20% Build & repair cells & tissues Made from amino acids
20 necessary, essential (complete)

7. Proteins Provide long-term energy: 4 calories per gm
Basic body components
Amino Acids (22) – 9 essential
Complete: animal sources
Incomplete: vegetable sources

8. Carbohydrates: 50-60% 2/3 of daily energy needs Simple: sugars
Complex: grains, fruits, etc.

9. Carbohydrates Major source of energy – 4 calories per gm
Found in cheaper food sources
Provide fiber

10. Fat: 30% Concentrated energy Transport Vit A,D,E,K Saturated – solid
Unsaturated - liquid

11. Fats/Lipids Concentrated energy – 9 calories per gm
Fat soluble vitamins: a,d,e,k
Flavor source
Saturated: hard – bad
Unsaturated: soft - good

12. HDL vs LDL
Lipoproteins that carry cholesterol and triglycerides in the blood
HDL – good: clean arteries by taking lipids to liver for elimination
LDL – bad: primary risk factor for heart attack (clog arteries)

13. Vitamins
Needed for essential functions
Water soluble
Fat soluble

14. Minerals
Regulate body fluids
Growth
Build tissues

15. Water No calories 65% of body
Needed for fluid balance, as solvent, to aid digestion, & remove waste

16. Water
Essential for digestion
Plasma
6 – 8 glasses
Reabsorption

17. Water Problems
Dehydration – severe loss of water (fever, vomiting, diarrhea)
Edema – severe retention of water (kidney disease, heart failure)
Pitting edema – leaves indentation on body part (1 – 4 plus)

Anemia: Need iron. Found in liver, egg yolks, dark green veges, beans, fortified foods.

20. Modified Diets Cancer: Need calories & vitamins A, C, D & E.
Diabetes: Modifies blood sugar levels. Food exchanges divided into 6 areas.
Heart disease: Lower cholesterol, triglycerides and calories.

21. Processes Digestion – change food physically
Absorption – move from digestive to circulatory systems
Metabolism – change food to energy in cells
