There are many types of plant-based diets, but they all emphasize certain foods associated with heart benefits.

Such plant-based diets are whole grains, fruits, vegetables, legumes, nuts, and healthy oils like olive oil. The diets that have been most studied for their impact on heart health include the Mediterranean diet, the DASH diet, and the MIND diet.

These diets are rich in fiber, vitamins, and minerals that help lower blood pressure and LDL (bad) cholesterol, reduce the risk of diabetes, and help maintain a healthy weight, all of which can lower your risk of heart disease.
