Plant protein swap may boost heart health, researchers say

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 metabolic health. No new experiments are being done; instead, the researchers are combining results from past studies to get clearer answers. The findings could help shape future nutrition guidelines for everyone, especially those at risk for diabetes and heart disease.
