Lower Protein May Boost Healthy Aging
A new review of over 350 studies suggests that reducing protein intake may improve metabolic health and potentially extend lifespan. While protein is essential for muscle growth, researchers argue that many sedentary individuals consume more than necessary, which may have long-term health drawbacks.
Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water.
