The Good-Skin Diet:

As beauty products get more high-tech, the top complexion cures still come from the most natural quarters: the aisles of your super?market. "Increasingly, studies are finding links between certain nutrients and wrinkle reduction, radiance, and acne prevention," says David Bank, MD, a dermatologist in Mount Kisco, New York. Here are 10 cream-of-the-crop ways to nourish your skin from the inside and out.
 Get Glowing with Chocolate

Cocoa hydrates your skin, making it firmer and more supple, Dr. Bank says. "And dark chocolate contains high levels of flavonols, a potent type of antioxidant," adds Nicholas Perricone, MD, a dermatologist in New York City. For maximum flavonol content, eat chocolate that's at least 70 percent cacao. A couple of squares a day should be enough to improve luminosity. "When applied topically, the caffeine in chocolate may temporarily reduce skin puffiness," says Jessica Wu, MD, a dermatologist in Los Angeles and the author of Feed Your Face. Try cocoa-rich 100% Pure Cocoa Kona Coffee Body Cream ($15, 100percentpure.com).


 Prevent Wrinkles with Yogurt

The protein you get from eating dairy helps skin become firmer, so it's more resistant to lines, Dr. Wu says. Greek yogurt is especially beneficial. "The protein content is often double that of regular yogurt," Dr. Perricone adds. Eat a single serving daily to make your complexion smoother, and apply Korres Yoghurt Instant Soothing Gel ($38, sephora.com) to calm irritated, dry, or sensitive skin.

 Protect with Pomegranates

They're packed with polyphenol antioxidants, Dr. Perricone says. Polyphenols fight free radicals and regulate skin's blood flow, giving it rosiness. One pomegranate or a few glasses of juice daily should do the trick. When applied to skin, the fruits' antioxidants help smooth lines and moisturize, Dr. Bank says.

 Soften Skin with Walnuts

"Walnuts contain omega-3 essential fatty acids, which can improve skin's elasticity," Dr. Bank says. The nuts are also loaded with copper, a mineral that boosts collagen production. Snack on a handful of walnuts each day to improve your complexion's texture, and slough tough calluses with True Blue Spa Smoothing Foot Scrub Toe the Line ($15, bathandbodyworks.com). The ground walnut it contains acts as an exfoliant.
