If you’re determined to stay healthy this winter, make sure your diet includes lots of apples, red grapes, blueberries, onions, broccoli, turmeric, green tea and red wine. These flu-fighting foods are all good sources of a plant chemical called quercetin. New research shows that quercetin fights viruses. In animals that were stressed by extreme exercise, and then exposed to a flu virus, supplemental quercetin kept them from “catching the bug.”
Researchers say quercetin may work the same way in humans, and be especially helpful for endurance athletes, soldiers and others undergoing difficult training regimens, as well as people under psychological stress.
The Anti-Aging Bottom Line: Good nutrition goes a long way toward flu prevention and warding off other contagious illnesses. Make sure to include plenty of foods high in quercetin in your diet and take a quercetin supplement for added protection.
