Potatoes
Potatoes have earned a pretty bad reputation since they are high in carbs, though that does not negate their other health benefits. This root crop comes with high amounts of vitamins, fiber, zinc, iron, and potassium which your body need in order to function properly. These minerals and vitamins help bring down blood pressure and cholesterol levels which will definitely keep your heart in check.
Barley
Barley should be a mainstay grain in your house since it is rich in vitamin B6, potassium, and fiber. It has the ability to decrease your cholesterol levels and ultimately improve your cardiovascular health. While there are many reasons to indulge in it, it might be a good idea to stay away if you have celiac disease as it has gluten.
