Question

Name of the food product: Oreos

Mass of food types in one serving:

total Calories per serving: 160 Cal

carbohydrates: 25 g Fat: 7 g Protien: 1 g

Calculate the kcal per serving.....

carbohydrate: _____ kcal

fat: ______ kcal

Protien: _______ kcal

What are the total calories (kcal) per serving?

What percent (%) of the total Calories in your food product is from fat?

What percent (%) of the total Calories in your food product is from carbohydrate?

What percent (%) of the total Calories in your food product is from protien?

How does your calculated number of Calories compare to the Calories listed on the label of the food product?

note that 1 kcal = 1 Cal

typically

1 g of fat = 9 Cal

1 g of protein = 4 Cal

1 g of carb = 4 Cal

so:

carbohydrate serving energy = 25*4 = 100 kcal

fat serving energy = 7*9 = 63 kcal

protein serving energy = 1*4 = 4 kcal

total = 100 + 63+4 = 167 Cal

now, % calories:

% from fat = cal of fat / total calories 100% = 63/167 *100 = 37.724 %

% from carbs = cal of carbs/ total calories 100% = 100/167 *100 = 59.880 %

% from protein = cal of protein / total calories 100% = 4/167 *100 = 2.39520 %

the label is pretty near, since ratio is 160 vs. 167
