What physiological change in older adults can result from low protein intake?

Low protein intake in older adults can lead to muscle wasting, a condition characterized by the loss of muscle mass and strength. As individuals age, maintaining muscle tissue becomes increasingly vital for overall health, functional mobility, and independence. Adequate protein is essential for the synthesis of muscle proteins; therefore, insufficient protein consumption can hinder this process, resulting in a decrease in both muscle quantity and quality.

Muscle wasting is particularly concerning in older adults because it is associated with an increased risk of falls, frailty, and various health complications. This decline in muscle mass can also impair metabolic functions, as muscle tissue plays a crucial role in glucose metabolism and overall energy expenditure. Consequently, ensuring that older adults meet their protein needs can help mitigate the risks associated with muscle wasting and support better physical function and quality of life.
