/.6 classes of nutrients - Answer-carbohydrates, fats, proteins, vitamins, minerals, water
/.Total grams x calories per gram calculation and percentage - Answer-ex.
144 g carbs -- (4 kcals/g)
12 g protein -- (4 kcals/g)
60 g fats -- (9 kcals/g)
(144 g x 4 kcal/g) = 576 kcals from carbs
(12 g x 4 kcal/g) = 48 kcals from proteins
(60 g x 9 kcal/g) = 540 kcals from fats
Total calories = 1164
What percent of calories come from fat?
(540 kcals/1164 kcals) x 100 = 46% from fat

/.Nutrition recommendations are confusing because - Answer-they are always changing
, /.Nutrition Research Steps - Answer-Step 1: form a hypothesis
Step 2: conduct an experiment to test the hypothesis
Step 3: share findings in a peer-reviewed journal
/.Consensus - Answer-When researchers agree with your findings/theory
/.Observational research - Answer-looking at factors in two or more groups of subjects
to see if there is a relationship to certain health outcomes

meet the needs of about 50% of people of same age/gender
/.Recommended Dietary Allowance (RDA) - Answer-average amount of nutrient that
meets the needs of nearly all individuals of the same age/gender (97-98%)
/.Adequate Intake (AI) - Answer-Same as RDA but less scientific data to determine than
RDA (so a weaker recommendation)
/.Tolerable Upper Intake Level (UL) - Answer-highest amount of nutrient that is unlikely
to cause harm if consumed daily
/.Acceptable Macronutrient Distribution Range (AMDR) - Answer-Carbs: 45-65% of daily
calories
