Which fruit is specifically noted for being rich in the flavonoid antioxidant *quercetin*, often concentrated in its skin?
Answer
Apples
Apples, particularly when the skin is consumed, are highlighted as being rich sources of quercetin. Quercetin is classified as a powerful flavonoid antioxidant that is strongly associated with protective health benefits, including reducing inflammation and potentially contributing to improved heart health outcomes. The text notes that the specific variety matters, suggesting darker-skinned apples often harbor higher concentrations of these beneficial polyphenols. While kiwis also contain protective compounds like Vitamin E and carotenoids, quercetin is specifically attributed to the apple's antioxidant profile.
