Yep, eating an apple, a day does help keep the doctor away. Eating an Apple fills your tummy and bowel with healthy fiber which helps to regulate your blood sugar. Apples are extremely rich in important antioxidants, flavonoids, vitamins and dietary fiber. The phytonutrients and antioxidants in apples may help reduce the risk of developing cancer, hypertension, diabetes, and heart disease. Try eating a couple of apples a day and notice the change in your health. Low in calories too as they are 85% water so they help with hydration.
