Association Between Plant and Animal Protein Intake and Overall and Cause-Specific Mortality

Key Points

Question: Does an association exist between dietary protein choice, particularly from various food sources, and long-term overall mortality or cause-specific mortality in the US population?

Findings: In this cohort of 237, 036 men and 179, 068 women with 16 years of observation and nearly 78,000 deaths, greater intake of plant protein was significantly associated with lower overall mortality and cardiovascular disease mortality independent of several other risk factors.

Meaning: This study provides evidence for public health recommendations regarding dietary modifications in choice of protein sources that may promote health and longevity.
