52: Optimal Protein Intake for Healthy Aging
Description
This episode does a deep dive into an article that argues that the current Recommended Daily Allowance (RDA) of 0.8 g protein per kg of body weight for adults is insufficient for older individuals, particularly for maintaining skeletal muscle mass and mitigating sarcopenia. Furthermore, the article dismisses common concerns that higher protein intake negatively affects renal and bone health, citing a lack of scientific foundation for these claims in healthy individuals. The authors also suggest that a more even distribution of protein intake across daily meals could be an optimal strategy for muscle maintenance in the elderly.
