Question

A ground turkey label indicates that it is 90% lean. The Nutrition facts panel shows that a serving of this food has 170 cal and 8 g of fat. What is the % fat calories in this food?

a) 42%
b) 10%
c) 90%
d) 5%

Answer 1

The percentage of fat calories in a serving of the ground turkey is calculated by multiplying the grams of fat by 9 to get the calories from fat and then dividing by the total calories of the serving. This results in about 42% of the calories coming from fat.

Step-by-step explanation:

To calculate the percentage of calories from fat in the serving of ground turkey, we use the information given on the label that a serving contains 170 calories and 8 grams of fat. Since fat has 9 calories per gram, we can calculate the calories from fat as:

Calories from fat = 8 g × 9 cal/g = 72 cal

Now, we need to find out what percentage of the total 170 calories come from fat:

Percentage of fat calories = (Calories from fat / Total calories) × 100

Percentage of fat calories = (72 cal / 170 cal) × 100

Percentage of fat calories = 42.35%

So, the closest answer by rounding down would be (a) 42%.
