Systematic Review With Meta-Analysis
Human
2025 Mar 17

This study found that eating more healthy plant foods like fruits, veggies, and whole grains lowers your risk of dying from any cause, while eating more unhealthy plant foods like sugary snacks and refined carbs raises your risk — and the more you eat of each, the stronger the effect.
