Hereâs some health news about a particularly powerful flavonoid. Itâs called quercetin, and it could help fight free radicals. These particles are responsible for damaging cell membranes, screwing up DNA, and even killing off healthy cells. Theyâre the sort of particles you donât want roaming around your body, because they can cause cancer, heart disease, and Alzheimerâs disease.
One way to put the brakes on all this damage is to eat a diet high in quercetin. Quercetin is an antioxidant that knows how to neutralize free radicals so that they donât run rampant throughout your body, messing with all your cells. As an added benefit, quercetin may play a role in neutralizing LDL cholesterol, too, protecting your heart from disease.
Just how good is quercetin at preventing oxidative damage? In a recent study performed at the University of South Florida, researchers evaluated the antioxidant power of a group of flavonoids. When all the tests were done, two flavonoids stood out: catechin and quercetin. They sound like twins, and in a way, they are.
Catechins are also antioxidants that fight oxidative damage. But, according to the researchers, quercetin has a nearly 10-fold higher antioxidative effect than catechinâwhich is not to say you donât need catechin. Youâll want to make sure you continue to drink green teaâan excellent source of catechins. But, to really boost your free radical neutralizing power, get some quercetin every day. Add these foods to your diet: citrus fruits, apples, onions, parsley, sage, tea, and red wineâall excellent sources of quercetin.
