Question

Determine the calorie content of 2 tablespoons of peanut butter and calculate the percent of calories coming from fat, protein and carbohydrates. Nutrition content for 2 tablespoons of peanut butter: Fat 16 g Carbohydrate 16 g Protein 18 g Fiber 2 g Part 1: First, you will need to calculate the total calorie content that comes from each of these nutrients.

Answer 1

Answer:

There are 280 Kcal in 2 tablespoons of peanut butter.

Toral calorie content :

Fat = 144  Kcal

Carbohydrates = 64  Kcal

Protein  = 72  Kcal

Fiber  = 0

Percent of calories :

% of calories coming from fat = 51.2 %

% of calories coming from protiens = 25.7 %

% of calories coming from carbs = 22.8 %

Explanation:

As we know 1 g of a carbohydrate and protiens contains 4 Kcal while 1 g of fat contains 9 Kcal. and fibre contains zero calories.

Hence the calculation is as follows.

Fat = 16g x 9 = 144  Kcal

Carbohydrates = 16g x 4 = 64  Kcal

Protein = 18g x 4 = 72  Kcal

Fiber = 2g x 0 = 0

Total calorie count = 144+64+72+0= 280 kcal

% of calories coming from fat = 144/280 x 100 =51.2%

% of calories coming from protiens = 72/280 x 100 =25.7 %

% of calories coming from carbs = 64/280 x 100 = 22.8
