Eating less protein could slow aging, major review finds
A comprehensive review suggests that reducing protein intake may offer health benefits, including improved metabolism and potentially increased longevity. While protein is essential for muscle growth, the researchers argue that many sedentary individuals consume more than necessary.
Why it matters
This challenges current dietary trends favoring high-protein consumption and offers a potential alternative to calorie-restricted diets for health improvement.
Protein-enriched products now fill grocery store shelves, appearing in everything from cereal and coffee to water. Yet a new review of more than 350 studies on protein restriction and aging suggests that many people may gain more from eating less protein, and that lower intake could sometimes contribute to a longer life.
Published July 31 in the Cell Press journal Cell Press Blue , the review examines how reducing protein may influence aging. The researchers conclude that protein restriction can improve metabolism, alter the way cells react to nutrients, limit cellular damage, and help cells maintain normal function.
