Final answer:
To compare nutrient contents of two granola bars, use the Nutrition Facts Label, which provides the % Daily Value and ingredient information necessary to make a healthful choice. (option 3)
Step-by-step explanation:
To compare nutrient contents of two brands of packaged granola bars and make a more healthful choice, the Nutrition Facts Label is the most direct tool. The Nutrition Facts Label provides information on the nutrient content and ingredients in food and includes the percent Daily Value (% DV) of nutrients.
These percentages help you determine if a food is high or low in a particular nutrient based on a 2,000 calorie daily diet. For instance, nutrients with a % DV of 5 or less are considered low, whereas those with a % DV of 20 or more are high. You'll also want to check the ingredients list for whole grains, vegetables, and fruits, and avoid processed ingredients.
While the other options provided, such as MyPlate, Recommended Dietary Allowances (RDA), and the Food Pyramid, are helpful for overall dietary guidance, they are not as effective as the Nutrition Facts Label for directly comparing specific products.
Hence, the answer is option 3.
