New study links high protein diets to shorter lifespans

Experts warn against high consumption of animal-based proteins for longevity.

Excessive Animal Protein Linked to Shorter Lifespan

Recent studies reveal that many Americans consume double the recommended daily intake of protein, particularly from animal sources. Experts highlight that while protein is vital for health, excess intake from animal-based foods can negatively impact longevity. Dr. Suzanne J. Ferree emphasizes that older adults require more protein, contrasting the common belief that they should limit their intake. However, the type of protein consumed matters greatly. Dr. Monisha Bhanote points out that overconsumption of animal protein, which many people mistakenly believe supports health, may actually reduce lifespan.

The growing evidence suggests a shift in dietary focus is essential. While protein is crucial for maintaining muscle mass, especially in older adults, the source of that protein must be plant-based for optimal health benefits. Health authorities and experts are increasingly recommending diets lower in animal products and higher in plant proteins. This aligns not only with individual health but may also challenge prevailing dietary norms in American culture. As awareness of dietary impact on longevity increases, so too does the urgency for public health messages to evolve accordingly.
