What specific advantage do red onions typically demonstrate compared to white or yellow varieties?
Answer
Higher levels of beneficial antioxidants like Quercetin
Red onions are specifically highlighted as boasting higher concentrations of beneficial antioxidants, particularly quercetin, when contrasted with their white or yellow counterparts. While all onions contain quercetin, the deeper pigmentation in red onions correlates with a richer supply of these protective flavonoids. This superior concentration means that when seeking the maximum antioxidant contribution from onions, choosing the red variety is recommended, as it contributes more substantially to the diet's overall antioxidant profile.
