3. Bran Muffin
While bran muffins might seem like a healthy breakfast choice to support your heart health, they are not. Most bran muffins sold in restaurants and stores are full of sugar. Getting too much sugar in your diet significantly increases your risk of dying from cardiovascular disease. Not only do these muffins have lots of sugar, but they usually have refined flour, salt, and oil—all of which are bad for the heart in excess.
