High cholesterol and weight issues increase the risk of heart attacks—this is a major problem. As a solution, a new study found that eating mostly oatmeal for just two days can "reset" your body. The benefit is that this simple change cuts bad cholesterol by 10%, lowers blood pressure, and helps with weight loss. Because oatmeal feeds good gut bacteria, the healthy effects can last for over a month, making it a quick and natural way to protect your heart.
