Protein and Aging

Lowering IGF-1 and growth hormone signaling can yield significant benefits in longevity, though not as dramatic as mutations found in some animal models. Interestingly, the relationship between protein intake and cancer risk shifts after age 65, suggesting that older adults may not benefit from protein restriction as younger individuals do. Maintaining a healthy weight becomes crucial as aging can lead to unintentional weight loss, emphasizing the need for a balanced approach to nutrition in later life.
