This review suggests the type of protein you eat may matter as much as the amount.
Older adults are usually told to eat more protein. This review of the science argues the opposite may help metabolic health and lifespan, at least in animals. Cutting back on three specific amino acids (methionine, isoleucine, and valine) seems to deliver much of the benefit on its own. The catch: most of this evidence comes from animals, not people, and older adults still need protein to protect muscle.
