What are the assumptions made by the DRI Committee in setting the RDA for protein?
What will be an ideal response?
The body continuously breaks down and loses some protein and it cannot store proteins or amino acids. To replace protein, the body needs dietary protein for two reasons. First, dietary protein is the only source of the essential amino acids, and second, it is the only practical source of nitrogen with which to build the nonessential amino acids and other nitrogen-containing compounds the body needs. Given recommendations that fat should contribute 20 to 35 percent of total food energy and carbohydrate should contribute 45 to 65 percent, which leaves 10 to 35 percent for protein. In a 2000-kcalorie diet, that represents 200 to 700 kcalories from protein, or 50 to 175 grams. The average intake in the United States is 80 grams per day.
