Fix Your Health Problems With Food
The food fix: Pile on protective produce
While you still need the usual sun protection (SPF 30 sunscreen as well as a wide-brimmed hat), you may be able to bolster your skin's own resistance to UV rays with what you eat. The details: Micronutrients called carotenoids in fruits and vegetables protect the skin against sunburn, recent science shows. "Most topical sunscreens work by filtering out the UV component from the solar light that reaches the skin," explains researcher Wilhelm Stahl, PhD, a professor of biochemistry at Heinrich Heine University in Düsseldorf, Germany. "But these micronutrients, if you have enough in your system, actually absorb UV light and prevent damage."
The most potent carotenoids are the beta-carotene found in carrots, endive and spinach, and the lycopene in watermelon and tomatoes. Keep in mind that the effect isn't instantaneous; you would need to eat a carotenoid-rich diet for at least 10 to 12 weeks in order to get the full benefit, says Stahl. Still, there is a reward for your patience: skin fortified to fend off sun damage and wrinkles.
