The Study
The Impact of Plant-Based Diets on Cardiovascular Health: A Comprehensive Review
This study is like a summary of many other studies that looked at people who ate more plants and found they tended to have healthier hearts — but it didn’t do any experiments itself. So we can say plants might be linked to better heart health, but we can’t say eating plants definitely causes it.
