Researchers say what you eat may help protect your skin from the sun’s harmful rays.

A new study, published in the journal Nutrition Reviews, has found that a Mediterranean-style diet, rich in antioxidants and omega-3 fatty acids, can help protect against skin cancer.

Lead researcher Dr. Niva Shapira explains that previous research has shown that the sun’s UV rays damage the skin by exciting its molecules and causing them to become oxidized "My theory was that if you prepared the body with sufficient and relevant antioxidants, damage could be reduced," she says.

Researchers divided participants into two groups – one that received a drink high in antioxidants, and one that was given other beverages, such as sodas, while undergoing daily sun exposure for a two-week period.

They found that those who drank the antioxidant-rich beverage had 50 percent fewer oxidation products in their blood at the end of the study, compared to those who drank other things.

Researchers say that the antioxidants delayed the phenomenon of skin erythema, which indicates the initiation of tissue and DNA damage that can lead to skin cancer.

Among the "sun-smart" foods found in the Mediterranean diet are olive oil, fresh fish, fruits and vegetables, as well as red wine in moderation, whole grains, beans and lots of water.

In addition to eating these foods, researchers say that regular applications of sunscreen and appropriate body coverings such as hats and beach cover-ups remain essential as well.
