Question

3. The nutritional label of a package of cookies lists the serving size as 1 cookie that weighs 28.4 g. The total fat per serving size is listed as 7 g with 1.7 g of saturated fat listed. (a) What is the percent fat in the cookies? (b) What percentage of the total fat is saturated fat? (c) Assume a 2000 calorie diet as ideal and that there are 9 calories in a gram of fat.

(d) Considering that the American Heart Association recommends no more than 20-35% of calories to come from fat comment on your answer to (c) above.

Explanation / Answer

Serving size = 1 cookie

Weight of 1 cookie = 28.4 g

Total fat = 7 g

Saturated fat = 1.7 g

Part a

% fat in cookie = Total fat*100/Weight of 1 cookie

= 7*100/28.4

= 24.648%

Part b

% of Saturated fat = Saturated fat * 100/Total fat

= 1.7*100/7

= 24.285%

Part C

1 g fat contains = 9 calories

Student eats = 10 cookies

Student eats cookies in g = 10 cookies x 28.4g/cookie

= 284 g

Total fat taken = 284 g x 24.648/100 = 70 g

Total calories consumed = 70 g x 9 calories /g = 630 calories

Part d

Total calorie diet = 2000 calories

Calories from fat = 630 calories

% calories from fat = 630*100/2000 = 31.50%

It is not recommended for a person to take such a diet in which 31.5% calories come from fat. The person should avoid to eat so many cookies.
