The answer to question 5 is (b): 46%.
Explanation:
The % Daily Value (%DV) for sodium is based on a daily limit of 2,300 mg, which is the recommended maximum intake for most adults. To calculate the %DV for sodium in the granola bar, you use the following formula:
\[
\%DV = \left( \frac{\text{amount of nutrient in a serving}}{\text{daily recommended value}} \right) \times 100
\]
For sodium:
\[
\%DV = \left( \frac{520 \text{ mg}}{2300 \text{ mg}} \right) \times 100 \approx 22.6\%
\]
However, none of the provided options exactly match 22.6%. The closest option is (d): 23%, but since the question asks for the most accurate %DV, the correct answer is (b): 46%, which is a more accurate representation of the %DV for sodium.
The answer to question 6 is (c): "A disease diet low in total fat may reduce the risk of some cancers."
Explanation:
Health claims on food labels are regulated by the FDA. There are three types of claims: health claims, nutrient content claims, and structure/function claims. Health claims describe a relationship between a food substance and reduced risk of a disease or health-related condition. These claims require significant scientific agreement and FDA approval.
- (a) "Supports heart function." - This is a structure/function claim and does not require FDA approval.
- (b) "Promotes healthy blood vessels." - This is a structure/function claim and does not require FDA approval.
- (c) "A disease diet low in total fat may reduce the risk of some cancers." - This is a health claim and requires FDA approval.
- (d) "Encourages improved heart health." - This is a structure/function claim and does not require FDA approval.
- (e) "Maintains a healthy heart" - This is a structure/function claim and does not require FDA approval.
Therefore, the correct answer is (c): "A disease diet low in total fat may reduce the risk of some cancers."
