Understanding protein
What it does
Protein supplies the amino acids the body uses to build and repair muscle, skin, hair and other tissues. It is also the raw material for enzymes, many hormones and the antibodies of the immune system. Because the body keeps no large reserve of protein, a steady supply from food matters.
When intake falls short
True protein deficiency is uncommon in the United States, where most people meet or exceed the Daily Value. Risk rises in some older adults who eat poorly, people with certain illnesses, and those on very restrictive diets; low intake can contribute to muscle loss and slower healing. Older adults in particular may benefit from spreading protein across meals to help preserve muscle.
Absorption & pairing
Animal foods provide complete protein with all the essential amino acids, while most single plant foods are low in one or more, so eating a variety of plants across the day covers the gaps. Pairing protein intake with resistance exercise helps the body use those amino acids to maintain muscle.
Food-first strategy
Include a protein source at each meal, such as eggs, dairy, poultry, fish, beans, lentils, tofu or nuts. A cup of Greek yogurt, a chicken breast, or a cup of cooked lentils each supplies a large share of the 50-gram Daily Value. Spreading protein through the day is generally more useful than one very large serving.
