What classification of antioxidant is Quercetin, which onions are celebrated for having high concentrations of?
Answer
Flavonoid
Quercetin, the star antioxidant found prominently in onions, is specifically identified as a flavonoid. Flavonoids are a diverse group of plant metabolites recognized for their strong antioxidant capabilities, meaning they play a crucial role in combating damaging free radicals throughout the body. While garlic's main benefit centers on organosulfur compounds like allicin, the onion's primary chemical superpower in this context is its high concentration of quercetin, distinguishing its general antioxidant defense mechanism from garlic's specialized focus.
