Nutrition

Macronutrients
  * Energy Yielding Nutrients
  * Relatively Large Molecules
  * CHO, Fat, PRO
  * All the body’s activities are fueled by the energy-yielding nutrients: CHO, Fat, and PRO
Metabolism: the process by which nutrients are broken down to yield energy or rearranged into body structure.
Micronutrients
  * Non Energy Yielding Nutrients
  * Vitamins, Minerals, and Water
Inorganic
  * Not containing Carbon or pertaining to living things Ex:   Minerals and Water ( Hydrogen, Oxygen and Minerals)
Organic
  * Containing carbon-carbon bonds or carbon-hydrogen bonds, “alive” Ex: CHO, Lipids, PRO, Vitamins ( Carbon, Hydrogen, Oxygen, and Nitrogen )
Functional Foods
  * Foods that contain physiologically active compounds that provide health benefits beyond their nutrient compositions
  * Whole, modified and fortified
      * Oatmeal has shown to lower LDL cholesterol levels
      * Margarine made with plant sterols that lower cholesterol
      *   Orange juice fortified with calcium to help increase strong bones

Kcalories
CHO: 4 kcal per gram
PRO: 4kcal per gram
Fat: 9 kcal per gram
Alcohol: 7 kcal per gram
% kcalories from food
Example:
Whole Milk has
13g of CHO                                     13g x 4kcal= 52 kcals
8g of PRO                                           8g x 4kcal= 32 kcals
8g of Fat                                             8g x 9kcal= 72 kcals
                                                                          = 156 kcals
52 kcals CHO / 156 total kcals =.33 x 100 = 33%
32 kcals PRO / 156 total kcals = .21 x 100 = 21%
72 kcals Fat / 156 total kcals = .46 x 100 = 46%
Double Blind Experiment: researchers and subjects do not know which subjects are members of the experimental group
Anthropometric Data: Height, Weight, Head Circumference, Body Max Index
Historical Information: Socioeconomic History, Drug History, Diet History, 24 hour Recall, Usual Intake, Food Record, and Food... [continues]
