Did you know that kiwis have more vitamin C than oranges? Kiwis are helpful foods for skin health because vitamin C is a powerful antioxidant that help zaps free radicals in cells. Some studies show that vitamin C may protect skin against UV damage, help with the production of collagen, and make skin more hydrated. Eat kiwis when they’re fully ripe, as this is when they have the most antioxidants. Other good sources of vitamin C include blackcurrants, blueberries, citrus fruits, guava, red peppers, parsley, strawberries, and broccoli.
