Top 10 anti-ageing foods

Onions

Yellow, and especially red (but not white), onions provide very high levels of quercetin, an antioxidant of the flavonoid family and an important
anti-inflammatory. Inflammation is a factor in many age-related conditions, including arthritis, and possibly loss of skin elasticity. Frying onions does not reduce their quercetin content.

Alternatives? Apples, tea and green beans.
