5 fruits that make you look younger

You can head off a lot of your most common beauty concerns simply by downing the right foods. That's right—eating well not only does wonders for your waistline and bolsters your immune system but can also provide some very real get-gorg benefits, such as smoothing wrinkles, giving hair a glossy shine and strengthening flimsy nails.

"Your diet directly affects your day-to-day appearance and plays a significant role in how well you age," said Dr. Joshua Zeichner.

The smart approach, Zeichner said, is to create a plan that includes what he calls "the building blocks of healthy skin and hair"—nutrients, minerals and fatty acids—as well as antioxidants to protect your body from damaging environmental stresses.

Get ready to nab some beauty-boosting perks by tossing these essential face-saving edibles into your grocery cart.

Watermelon
The summertime fave is loaded with lycopene.

"This antioxidant compound gives watermelon and tomatoes their red color—and helps skin stave off UV damage," said nutrition pro Keri Glassman, RD, founder of NutritiousLife.com.

Researchers believe that the melon contains as much as 40 percent more of the phytochemical than raw tomatoes; that's the equivalent of an SPF 3, so use it to bolster (not replace) your daily dose of sunscreen.

Pomegranates
The seeds of this wonder fruit are bursting with antioxidants, like vitamin C, that prevent fine lines, wrinkles and dryness by neutralizing the free radicals that weather skin. A study in the American Journal of Clinical Nutrition found that higher vitamin C intake lessened the likelihood of dryness and wrinkles in middle-aged women. Also in the fruit's arsenal: anthocyanins (which help increase collagen production, giving skin a firmer look) and ellagic acid (a natural chemical that reduces inflammation caused by UV damage).

Blueberries
Boost radiance by popping some of these plump little beauties. Blueberries supply vitamins C and E (two antioxidants that work in tandem to brighten skin, even out tone and fight off free-radical damage), as well as arubtin, "a natural derivative of the skin lightener hydroquinone," Zeichner said.

Avocado
Like you need another reason to love them: These rich fruits are high in oleic acid, an omega-9 fatty acid that helps skin retain moisture in the outer layer to keep it soft, plump and supple, Bowe said.

Cantaloupe
The sweet melon contains beta carotene, or vitamin A, which is believed to regulate the growth of skin cells on your scalp and sebum in the skin's outer layer, Zeichner said. This keeps pores from getting clogged and causing flakes.
