An Apple a Day

An apple a day keeps the doctor away, as the saying goes. And not just any doctor. An apple may help keep the neurologist away – along the diseases like Alzheimer`s and Parkinson`s. Food scientist Chang Y. Lee found that an antioxidant, called quercetin, in apples can protect brain from damage. “Quercetin has much higher antioxidant activity compared to Vitamin C,” says Lee. His work shows that quercetin may help brain cells and hurt cancer cells. Apples are a main source of quercetin. It is also found in onions, tea, blueberries and cranberries. Choose a fresh apple over applesauce or apple juice for a snack. Lee suggests, because quercetin is found mostly in the skin of the fruit. “Processed food may lose active components,” he adds.
