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

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 Frequency...
