Protein Protein Presentation Transcript

  • Protein: Complete and Incomplete
  • 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!
  • Individual Protein needs can be influenced by….  Age / Gender  Body size  Health /wellness  Quality of protein consumed
  • 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
  • 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.
  • 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…
  • 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!
  • 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…
  • The best sources of complete (animal) protein….  Milk  Eggs  Fish  Poultry  Red Meat
  • 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…
  • The best sources of complete (plant) protein…. - Edemame (soy/tofu) - Beans / Legumes - Grains (wheat germ) - Brewers Yeast - Certain nuts - Cottonseed oil
  • Plant food combinations that make up a complete protein…  Peas and pasta  Red beans and rice  PB and wheat bread
  • 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.
  • 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
