What conditions require extra dietary protein?

Several conditions call for extra protein in the diet. Whenever more tissue is being built, more protein is required. Pregnancy, bodybuilding, strength training, and adolescent growth spurts place high demands for amino acids on the body. Lactating mothers are producing a quart or more of milk per day and thus need a higher-than-normal protein intake. People, especially athletes, restricting calories force the body to consume protein for fuel, depleting valuable amino acid stores, and must consume more protein to make up for the loss of other food groups in the diet. (These athletes should also add some carbohydrate to their diet.) Endurance athletes usually burn a certain amount of protein for fuel and need higher protein intakes than sedentary people. Vegetarians, especially vegans (consuming no animal products), will require somewhat higher protein intakes than people who are omnivores (eating all kinds of foods of both plant and animal sources), since much of their protein will be incomplete. Recent studies suggest that older adults may also be healthier with a little extra protein, about 1 g/kg body weight, as these people are at risk for breaking down muscle as they age, and extra dietary protein seems to slow down this process. Any combination of the above (e.g., pregnant vegans) will need more dietary protein, up to 1.2–2 g/kg body weight.
