Plant protein swap may cut heart & diabetes risk – but how much?
NCT ID NCT02037321
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is a review of many smaller trials that looked at what happens when people replace animal protein (like meat, dairy, eggs) with plant protein (like beans, nuts, seeds). The goal is to see if this simple swap can improve blood sugar, cholesterol, blood pressure, weight, and other markers of heart and diabetes risk. No new participants are being enrolled; instead, the researchers are combining data from past studies to get clearer answers.
