Diets with More Plant Protein Linked to Lower Risk of Death
Researchers from Massachusetts General Hospital examined how each protein source influenced long-term health. They looked at more than 131,000 adults participating in two long-running national health studies. Participants provided 25 to 30 years of detailed data on diet, lifestyle, and medical conditions. Researchers reviewed detailed food questionnaires that were sent to the participants every four years.
They found that higher intake of animal protein was positively associated with mortality and that the association was higher among adults who lived an unhealthy lifestyle. Substituting plant protein for animal protein, especially processed red meat, was associated with lower mortality, suggesting the importance of protein source.
