FSHN 1670 Exam 2 – Food Science and Human Nutrition – Review Notes and
Practice Material
What process is used to establish the Recommended Dietary Allowance (RDA)
for a nutrient? What would happen if we set the RDA to equal the Estimated
Average Requirement (EAR)? - ANS ✔✔A: 1. Make in EAR 2. Add margin of safety
B: Only half of the people would have nutrient needs met
You analyze your diet for a 24-hour period using Nutrition Calc Plus. You discover that your
estimated daily vitamin C intake was only 75% of the RDA. How do you interpret this
information? - ANS ✔✔It may not be deficient because it was only for a day, and one might not
need the recommended amount.
The Recommended Dietary Allowances (RDAs) are part of a set of nutrientintake standards
known as Dietary Reference Intakes (DRIs). The DRIs includeRDAs, Estimated Average
Requirements (EARs), Adequate Intakes (AIs),Tolerable Upper Intake Levels (ULs), and Chronic
Disease Risk Reduction(CDDR) levels. What is the intended use of each? - ANS ✔✔RDAS: meet
the needs of all healthy people
EARS: intakes that meet the estimated nutrient needs of 50% of individuals in a gender and life-
stage group
AIS: reference value when there is insufficient evidence
ULS: is possible to get to much of a nutrient
CDDR Levels: if you reduce level of that intake to prevent chronic diseases, like sodium.
What is the difference between a nutrient content claim, a health claim, and a
structure/function claim? Which claim must meet strict definitions established by the Food and
Drug Administration (FDA)? Which claim must first be reviewed and authorized by the FDA?
Provide an example of a food label claim that would be prohibited by the Food and Drug
Administration (FDA). - ANS ✔✔Nutrient Content Claim: claims about the contents of a nutrient
- must meet strict definition established by the FDA
, Health Claim: A longer claim, not allowed to say eat our product, and you will get a certain
health benefit. (reviewed by the FDA)
Structure/Function Claim: normal healthy structure and function of the body, "healthy bones."
Something not allowed: "Good source of fiber."
Does the serving size listed on the Nutrition Facts label reflect what consumers typically eat?
Why is that important? If a one-ounce serving of potato chips provides 160 calories, and you eat
half of an 8-ounce bag, how many calories did you consume? - ANS ✔✔A. Yes, and this is
important because all the nutrient label amounts shown on the label refer to the size of the
serving.
B. 640 calories
If one serving of your favorite food provides 5 grams of saturated fat, calculate the % Daily Value
for saturated fat. (Hint: The Daily Value for saturated fat is 20 grams.) If you eat two servings,
what percent of the Daily Value of saturated fat did you consume? - ANS ✔✔50%
What is the 5/20 Rule? If you consume a food that provides 60% Daily Value(DV) for saturated
fat in one serving, what does that mean for your food choices over the rest of that day? - ANS
✔✔A. The 5/20 Rule is a quick guideline for interpreting the % Daily Value (%DV) on Nutrition
Facts labels:
5% DV or less of a nutrient per serving is considered low.
20% DV or more of a nutrient per serving is considered high.
B. You've had 60% of your daily value, so for the rest pf the day you can only have 40% of your
daily value
What determines the order of ingredients in the ingredient list? - ANS ✔✔The order of
ingredients in a food's ingredient list is determined by their weight. Ingredients are listed in
descending order.
List features of the new Nutrition Facts label. How does it benefit consumers? - ANS ✔✔1.
