The Study
Replacing Animal-Based Proteins with Plant-Based Proteins Changes the Composition of a Whole Nordic Diet—A Randomised Clinical Trial in Healthy Finnish Adults
This study is like a fair test where people were randomly picked to eat different kinds of protein for 12 weeks — some ate mostly meat, some ate half meat and half beans, and some ate mostly beans. The ones who ate more beans had better blood numbers and ate more fiber. So we can say: swapping meat for beans in this setup really did change things for the better.
Analysis score

Where the score came from
People ate more beans, nuts, and whole grains instead of meat and dairy for 12 weeks — and their bad cholesterol went down.
