A couple of "tips" ago we talked about how right Mom was when she said, “Stand up straight.” Turns out she was also right when she said, “An apple a day keeps the doctor away.” Now, a new study backs her up. A natural antioxidant called quercetin, found in red apples as well as broccoli and green tea, may actually boost the immune system of individuals under stress.
In a study conducted by David Nieman, PhD, professor at Appalachian State University, results showed that only 5 percent of cyclists who took 1,000 milligrams of quercetin every day for five weeks reported upper respiratory illness during a two-week period following extreme exercise, whereas 45 percent of the cyclists who took a placebo reported illness following extreme exercise. So, during the holiday season (and year-round), along with finding time for some physical activity, snack on a big, red apple.
Keep in mind too, that whenever circulation is increased, you increase your white blood cells, so there are more cells to check for foreign germs and more to knock them out—a good thing to keep in mind during cold and flu season.
