What is a potential consequence of inadequate protein intake in older adults?

Inadequate protein intake in older adults can lead to muscle loss and increased frailty. As people age, the body’s ability to synthesize new muscle protein can decline, a condition known as sarcopenia. This age-related muscle loss can be exacerbated by insufficient dietary protein, which is essential for maintaining muscle mass and function.

When protein intake is low, the body begins to break down existing muscle tissue to meet its needs for amino acids, which can lead to decreased muscle mass, strength, and physical performance. This can significantly affect daily functioning and increase the risk of falls and other injuries, contributing to frailty—a condition characterized by reduced strength, endurance, and physiological function, making older adults more vulnerable to adverse health outcomes.

Maintaining adequate protein intake is crucial for counteracting these negative effects and promoting overall health and mobility in older adults. It supports not only muscle health but also contributes to various bodily functions, including repairing tissues, hormone production, and immune responses, although those options would not reflect the consequence of inadequate intake correctly in this context.
