1. Carbohydrate = 4 kcal/g 2. Protein = 4 kcal/g 3. Fat = 9kcal/g Example Calculation 4. Hamburger has 4 g carbohydrate, 3 g of protein and 5 g of fat. How many calories does protein it contain? it 5. 4 g carb X 4 kcals/g = 16 6. 3 g protein X 4 kcals/g = 12 7. 5g fat X 9 kcals/g = 45 8. Total = 73 kcals kcals kcals kcals Food Labels 0.

Whole milk: 8g of total fat 29.Whole milk high in fat = No health claim No 29.Whole 30.“Fat Free” = < 0.5 g fat per serving 31.“High source” = 20 % of the DV for a particular nutrient nutrient 32.“Low fat” = 3 g or less of fat per serving 32. Nutrition Terms Nutrition o Good source: 10-19% - Low source : 0- 5 % for daily value More Nutrition Terms

RDA’s: Recommended dietary allowance used to evaluate your current intake for specific nutrient. Less than 70% RDA or 3 times above RDA overtime can result deficiency or toxiciency AI: Adequate Intake, it implies further research is required before scientist can establish a more definitive number EERs: Estimated Energy requirement UL: Upper level -> used to evaluate the highest amount of daily nutrient intake that is unlikely to cause adverse health effects in almost all people in a population (97-98%) as intake increase above the upper level, the potential for adverse effects generally increase .
