What is the recommended protein intake for older adults per kilogram of body weight?

The recommended protein intake for older adults is typically between 1.0 to 1.2 grams of protein per kilogram of body weight. This higher protein intake compared to younger adults is essential because as people age, their bodies become less efficient at utilizing protein. Adequate protein is crucial for maintaining muscle mass, supporting metabolic functions, and promoting overall health during aging.

Additionally, older adults are at a higher risk for sarcopenia, the age-related loss of muscle mass and strength, and adequate protein intake can help mitigate this risk. Meeting the protein needs in this range can support better health outcomes, including improved physical function and reduced risk of frailty.

In contrast, lower protein intakes such as those suggested in the other options may not sufficiently support the unique nutritional needs of older adults, particularly those who are physically active or recovering from illness. These lower intake levels may hinder muscle maintenance and overall health in the aging population.
