Other Nutrients in Whole Grains

While fiber gets much of the attention, whole grains also provide other heart-healthy nutrients. Vitamins like E and B vitamins, plus minerals such as magnesium and potassium, all support heart function. These nutrients help regulate blood pressure and heart rate, lowering cardiovascular risks. Magnesium is especially important for relaxing blood vessels, which keeps blood pressure in check.

Antioxidants in whole grains also protect heart health by preventing cell damage linked to chronic diseases. The synergy of these nutrients with fiber makes whole grains a foundation of any heart-protective eating plan.
