| Biologically-Active Flavonoid From Specific Berries, Fruits and Vegetables Reduces Likelihood of Contracting the Flu Quercetin, the naturally-occurring, biologically-active flavonoid is present in a variety of fruits and vegetables, including grapes, blueberries, raspberries, strawberries, broccoli, onions and garlic as well as red wine. It provides powerful antioxidant activity and appears to protect against the flu. Subjects given Quercetin were less likely to contract the flu, according to a study published by The American Physiological Society. Interestingly, the study also found that stressful exercise increased the susceptibility to the flu, but Quercetin appear to cancel out that negative effect. Quercetin has been shown to have anti-viral properties in cell culture experiments and some animal studies, but none of these studies has looked specifically at the flu. The new study could help endurance athletes, soldiers and other people undergoing difficult training regimens, as well as people under psychological stress. This study builds on previous research. . . Quercetin was used because of its documented widespread health benefits, which include antiviral activity and reported lack of side effects when used as a dietary supplement or food additive. The research team examined four groups. Two groups performed three consecutive days of running to fatigue on a treadmill for a short period of stressful exercise. One group of runners received Quercetin, the other did not. The remaining two groups did not exercise. One non-exercise group received Quercetin while the other did not. All four groups were then exposed to a common flu virus, H1N1. The researchers found that: Stressful exercise increased susceptibility to the flu. The subjects that exercised to fatigue for three days were more likely to develop the flu than the subjects that did not exercise (91% versus 63%). The subjects that exercised developed the flu much sooner than those that did not (6.9 days versus 12.4 days). Those that exercised and took Quercetin had nearly the same rate of illness as those that did not exercise. Thus, Quercetin canceled out the negative effect of stressful exercise. Quercetin had protective effects for those that did not exercise. Quercetin supplementation was an effective preventive measure to offset the increase in susceptibility to infection that was associated with stressful exercise. | ||
