Document Summary

Calc: used to estimate total potential energy of a food sample. Human energy needs: energy is measured using the common unit of dietary energy known as the calories (cal) Calorie= quantity of heat needed to raise the temp of 1. 0g of water by 1 degree. Energy from foods = capital c (or kilocalories) Estimated energy requirement (eer) represents the average needs of a population. Measuring gross composition and energy content of foods. To solve for total kcals in food: 1. multiply weight of food (g) * composition (convert from % to decimal form) Quick check--- make sure that h20+ cho = weight of food. 3. g* kcals (may eliminate water step if needed on an exam because it will always be 0 kcal) Body operates like a complex chemical factory with a special rule: Reaction temperatures must be kept at 37 c (normal body temp) ----- 37 c * 9/5 + 32 = 98. 6 degrees f.
