Scientists Say Most People Need More Protein Than Current Guidelines - Video

A growing body of research suggests that current public health recommendations for exercise and protein intake may be sufficient to prevent deficiency, but may not be enough to support optimal health, healthy aging, and long-term independence.

A new paper published in Frontiers in Nutrition argues that many people could benefit from higher levels of physical activity and protein consumption than current guidelines typically recommend.

The review highlights evidence linking regular exercise to a wide range of health benefits, including lower risks of chronic disease and premature death, improved mental well-being, better cognitive function, and greater resistance to age-related decline.

According to the paper, combining aerobic activities such as walking, running, or cycling with resistance training may provide particularly strong benefits by helping preserve strength, mobility, and physical function as people age.

The paper also examines protein requirements beyond the minimum amounts needed to prevent deficiency. Current recommendations in many countries are largely based on sedentary adults, but newer research suggests that older adults, physically active individuals, and pregnant women may benefit from higher protein intakes.

The review further notes that higher-protein diets may aid body composition by increasing feelings of fullness and boosting the body's energy expenditure during digestion. Importantly, the author emphasizes that sufficient protein can be obtained through both animal-based and plant-based diets when meals are properly planned.

Rather than replacing existing public health recommendations, the paper calls for additional guidance focused on achieving optimal health outcomes rather than simply avoiding disease. The author argues that exercise and nutrition should be viewed as tools for maintaining physical strength, mental sharpness, and independence throughout life.
