Scientists dig through decades of diet studies: is plant protein really better for you?

This project is not a new treatment but a large-scale review of existing research. Researchers are analyzing data from many past diet studies to understand if replacing animal protein (like meat and dairy) with plant protein (like beans and nuts) improves health markers for conditions like diabetes, high blood pressure, and heart disease. The goal is to combine findings from many smaller studies to provide clearer evidence for future public nutrition guidelines.
