    • catabolism
  24. anaboilsm

    amino acids combine to form portein molecules
  25. catabolism
    breaking down of larger molecules
  26. essential nutrient
    cannot be manufactured by the body and therefore must be included in the diet
  27. nonessential nutrient
    can be created in the body
  28. BMR-basal metabolic rate
    the amount of energy used by a fasting resting individual to maintain vital functions

    determined by the amount of oxygen used
  29. calorie
    the rate by the amount of oxygen used and is defined in units of heat energy
  30. CHO- carbohydrates

    • peanuts
    • canola
    • peacans
    • avocados
  39. polyunsaturated fats
    have two or more unfilled hydrogen bonds are found in plants and are usually liquid at room temperature

    • safflower
    • corn
    • cottonseed
    • soy oils
  40. benefits of omega - 3 fatty acids
    • antinflammatory effects improve the immune response
