Question

Quizplus · Accepted Answer

The first statement is true; the second is false.Each gram of saturated fat,no matter which type,has 9 cal.Note that protein and carbohydrate each contain 4 cal/g.To calculate the percentage of kilocalories from fat,multiply grams of fat by 9 kcal/g of fat.Next,divide this result by the total number of calories consumed.In this case:
Step 1)120 g fat ´ 9 kcal from fat per gram of fat = 1080 kcal from fat.
Step 2)1080 kcal from fat ÷ 3000 cal consumed = 36% kcal consumed from fat.
