Most People Need More Protein Than Guidelines Recommend Scientists Say

A new review published in Frontiers in Nutrition argues that current public health guidelines for protein intake and exercise are designed to prevent deficiency, not to help people thrive as they age. Researchers from the University of Cambridge say physically active people, older adults, and pregnant women likely need significantly more protein than official recommendations suggest. The review also highlights the combined power of aerobic exercise and resistance training for preserving strength, mobility, and mental sharpness. Importantly, the authors note that higher protein goals can be met through plant-based diets with proper planning. The key message: minimum guidelines are a floor, not a ceiling, and aiming higher may meaningfully extend healthspan and independence.
