Question

In a protein supplement that contains 154 total kcalories, 11 grams of protein, and 17 grams of carbohydrate, how many kcalories come from protein and what percentage of this product's total kcalories are from the protein? Remember to explain why this is important information.

Answer 1

Answer:

As the calorific value of protein is about 4 kcal per gram. So, if any food supplement has 11 grams of protein, it signifies that it comprises 44 kcal of calorific value, that is, 11*4 kcal. In the given case, food supplement has 154 kcal as the total nutrition value, then the percentage of calorific value of protein from the total calorific value is:  

44 * 100 / 154 = 28.57 %.  

And this is as important information as protein is an essential constituent of the diet and the body requires an adequate amount of protein for the formation of muscles and other essential activities.  

Answer 2

Answer:

In this protein supplement there are 11 grams of protein which contribute with 44 kcalories. Therefore, the percentage of kcalories coming from protein in this particular supplement is 28,5 %.

Explanation:

Each gram of protein contributes 4 kcal (calories), so 11 grams of proteins x 4 kcal/gram = 44 kcal.

The total amount of kcalories is 154, so 44 kcal / 154 kcal x 100 = 28,5%.

When it comes to protein supplements is very important to realise how many proteins are being consumed and how many total calories this supplement has, for the simple reason that it might be not help to reach the protein goal for a particular individual, but instead, it might be providing too many calories that come from non-protein compounds.
