on average, ____ percent of daily energy intake should come from protein.
For example, if the label lists 20 percent for protein, it means that one serving provides 20 percent of the protein you need each day. The percent daily values are set by the FDA and are based on a 2,000-calorie diet. Average adults should consume between 10 and 35 percent of their daily calories from protein. If you are following a 2,000 calorie diet and wish to consume 30 percent of your calories from protein, you need 150 grams of protein daily. A diet with 10 percent of your calories from protein translates to 50 grams of protein.
