  1. 1. Protein: Complete and Incomplete
  2. 2. Protein has multiple functions  Builds and repairs body tissue  Provides Energy! •  Maintains cell growth Very important if body is growing rapidly, is injured or under stress!  Aids in the formation of enzymes, hormones and antibodies!
  3. 3. Individual Protein needs can be influenced by….  Age / Gender  Body size  Health /wellness  Quality of protein consumed
  4. 4. Protein must be consumed DAILY…  Constantly needed to replace wear and tear of tissue and keep up protein concentration in the blood  Protein CAN replace some fat and carbohydrates, but fat and carbohydrates CANNOT replace the body’s need for protein! RDA for boys= 5-6 oz. a day
  5. 5. Protein is necessary for strong BODY FUNCTIONS… * Protein can provide supplemental energy if sufficient fat and carbs. are not supplied. * Excess protein, once converted to energy, is stored as fat.
  6. 6. Lack of protein can lead to…..  Lowered resistance to disease!  Damage liver / eventual body shut-down and death!  Extreme fatigue!  Growth stunt…  Long term illness…
  7. 7. Necessary protein is made up of amino acids…. Amino Acids are “building blocks” from which new PROTEINS are made. CANNOT be supplied by the body and MUST BE consumed daily ! There are about many different body functioning amino acids, but 9 are essential for optimum health!
  8. 8. Complete Proteins:  Generally proteins derived from animal foods or animal food bi-products ;  Any food that has all 9 essential amino acids. Complete Proteins provide support for normal growth and body maintenance…
  9. 9. The best sources of complete (animal) protein….  Milk  Eggs  Fish  Poultry  Red Meat
  10. 10. Incomplete Proteins:  Are generally derived from plant foods •  Provide minimal support for normal body maintenance , DOES NOT support growth!  Some plant foods contain protein, but NOT all 9 essential amino acids…
  11. 11. The best sources of complete (plant) protein…. - Edemame (soy/tofu) - Beans / Legumes - Grains (wheat germ) - Brewers Yeast - Certain nuts - Cottonseed oil
  12. 12. Plant food combinations that make up a complete protein…  Peas and pasta  Red beans and rice  PB and wheat bread
  13. 13. Extending or “Sparing” Proteins….. •     Chicken and Rice Chili con carne Macaroni and Cheese Tuna Noodle Casserole “Sparing”Proteins: Adding carbs and or fats to a low protein diet for a more nutrient dense effect.
  14. 14. Vegetarian Diets…. Diets allowing adequate consumption of RDA for protein without consuming animal foods /bi-products. VEGETARIAN: = Consumes no meat, fish or poultry VEGAN= Only plant sources LACTO.VEGETARIAN = Consumes plant & dairy sources OVO.VEGETARIAN = Consumes plant, & egg sources LACTO.OVO. VEGETARIAN = Consumes plant, dairy & egg sources SEMI-VEGETARIAN= No red meat, some poultry & fish
