Question

The % Daily Value describes the amount of fat in a food. The % kcalories of fat describes the amount of fat in the diet. 1 tablespoon of butter and one tablespoon of sour cream (you might want to add to baked potato) provides 150kcalories and 13grams of fat. The Daily Value for fat based on a 2000 kCalorie diet is 65 grams (9kcal/g).

Best choice:
Percent Daily value:
Percent kcalories:

Answer 1

The %DV of fat for one serving of butter and sour cream with 13g of fat is 20% based on a 2000-kCal diet. The percent of kilocalories from fat for this food is 78%, calculated using the fact that fat provides 9 kilocalories per gram.

Step-by-step explanation:

The student is asking about the percent daily value (%DV) and the percent of kilocalories from fat based on a 2000-kilocalorie diet. To calculate the percent daily value of fat in a food item, we can compare the amount of fat in that item to the recommended daily total (65g of fat for a 2000-kCalorie diet). For instance, if a food product provides 13g of fat, the %DV would be calculated by (13g/65g) * 100, yielding a 20% daily value for fat.

When assessing the percent of kilocalories from fat, we must consider that fat has 9 kilocalories per gram. Therefore, in the given example of butter and sour cream providing 13 grams of fat, this equates to 13g * 9kcal/g = 117 kilocalories from fat. To find the percent of kilocalories from fat out of the total 150 kilocalories provided by the butter and sour cream, we would perform the calculation (117kcal from fat / 150 total kcal) * 100, resulting in 78% of the kilocalories coming from fat.
