A review of 350+ studies suggests protein restriction may promote healthier ageing in animals, but human evidence remains limited. Current evidence supports meeting protein needs through mostly minimally processed foods rather than reducing protein intake.Learning Outcomes
- Describe the current evidence on protein intake and healthy ageing, including the potential effects of protein restriction observed in animal studies and the limitations of applying these findings to humans.
- Evaluate the role of protein in human health across the lifespan, particularly its importance for maintaining muscle mass, supporting healthy ageing, and assisting with weight management.
- Apply evidence-based principles to dietary decision-making by considering overall dietary patterns, protein sources, and lifestyle factors rather than focusing on a single nutrient in isolation.
