The Claim

An overall plant-based diet index that reduces animal food intake but does not distinguish between healthy and unhealthy plant foods is modestly associated with an 8% lower risk of coronary heart disease in U.S. adult health professionals, indicating that simply replacing animal foods with any plant foods has limited benefit without attention to food quality.

In plain English

Eating more plants instead of animal foods might slightly lower your risk of heart disease, but only if those plants are healthy—like vegetables and whole grains—not junk food like soda or fries.

What the research says

  1. Study: Healthful and Unhealthful Plant-Based Diets and the Risk of Coronary Heart Disease in U.S. Adults.

    The study found that eating more plant foods instead of animal foods lowers heart disease risk a little — but only if those plant foods are healthy, like fruits and whole grains. If you eat unhealthy plant foods like soda or fries instead, it doesn’t help. So just swapping meat for any plants isn’t enough — quality matters.
