Ultraviolet radiation

Although sunscreen is important to prevent sunburn of the skin, there are also dietary measures you can take to help protect the skin against ultraviolet (UV) radiation damage to skin. UV radiation damage to the skin includes damage to both DNA and structural proteins. This damage leads to photoaging of the skin such as wrinkles, yellowing, roughness, dryness, abnormal pigmentation and a leathery appearance. 
Antioxidants can help prevent skin damage caused by UV radiation. Here are some foods that research has found to decrease skin damage caused by UV radiation:
Green Tea
Pomegranate Juice
Genistein, a phytoestrogen found primarily in Soy
Resveratrol found in grapes, nuts, fruits and red wine
Carotenoids, particularly lutein and zeaxanthin found in green leafy vegetables
Vitamin C and Vitamin E, especially in combination. Bell peppers, green leafy vegetables and strawberries are high in vitamin C while almonds and sunflower seeds are high in vitamin E.
Might I suggest frequent salads of green leafy vegetables with a soybean oil dressing topped with bell peppers, nuts and grapes partnered with a cup of green tea, wine or pomegranate juice this summer to keep your skin healthy?
