It's old news, I know. But new research keeps coming out to explain WHY and how apples are good for you. The most nutritious and high fiber part of the apple is: the skin. Apple consumption has been shown to fight cancer, aid digestion, reduce asthma in children when pregnant mothers eat apples, and decrease risk of lung cancer, heart disease and stroke.
How long has it been since you ate an apple? (Me: weeks...)
