How to Calculate Grams of Protein

Protein is an essential part of the diet. Proteins are consumed and digested into amino acids, which provide the nutrition required by the body's cells, tissues and organs. Some amino acids are produced by the body but others, the essential amino acids, must be obtained through diet. Foods such as meat, eggs and milk provide all of the essential amino acids, and are called complete proteins. Incomplete proteins lack some essential amino acids and include grains, seeds, nuts, fruits and vegetables. The total grams of protein in the diet and the dietary protein requirement are common calculations.

Instructions

1

Research the total grams of protein required in the diet by consulting a nutrition table. In general, adult men and woman require .4 grams protein for every 1 lb. of body weight. For example, a 180-pound man requires about 72 grams of protein daily. Athletes, growing children and teens may require more dietary protein than the average man or woman.

2

Create a list of all food consumed in a day. Determine the serving size and consult a nutrition table to find the grams of protein in each food.

3

Add the total grams of protein consumed and compare to the daily protein requirement. For example, a 72-gram requirement is met by consuming an 8-ounce broiled, lean steak (52 grams protein), cup of low-fat cottage cheese (14 grams protein) and 1 egg (6 grams protein).

4

Adjust the diet to meet the protein requirement. Consume complete proteins when possible or combine several incomplete proteins to ensure consumption of all essential amino acids. Excess protein in the diet is often stored as fat.
