The daily recommended amount of protein intake for adults in the United States is 56 grams for men and 46 grams for women. Pregnant women and athletes typically require more protein than the average person.
Proteins are commonly found in foods from animal sources, such as meat, poultry and eggs. Eating excessive protein does not provide additional benefits and can lead to increased fat and calorie intake, and many people do not need as much protein as they already eat daily. Pregnant women need about 10 more grams per day than the average, and breastfeeding women require 20 grams more. Athletes and bodybuilders can require from 50 to 100 percent more daily protein than a sedentary person.
