"This is a true story: To prep for my first job interview in the beauty industry, I ate only salmon and blueberries for one week because I was convinced it would make my skin glow-y. I don't really know if it worked. But I do know that I can barely look at salmon now. (If only they'd had BB creams then, right?)\\n\\n\\n\\n                   \\n\\nTurns out, there's no way to know if my skin-care diet was a good choice. That's because even though superfoods get a ton of hype, \\\"we don't have real data showing that supplements or certain foods make a difference to the skin,\\\" says Joshua Zeichner, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. But [a new study from Unilever ](http://onlinelibrary.wiley.com/doi/10.1111/ics.12087/abstract)may help change that. Participants were asked to take fish-oil supplements and down a drink with four antioxidants each day, and after two weeks, researchers found a significant improvement in the depth of facial wrinkles. The antioxidants were soy isoflavones (found in tofu and edamame), lycopene (big in tomatoes), vitamin C (OJ!), and vitamin E (plentiful in dark greens like spinach and swiss chard). \\\"The study supports the dietary recommendations that a lot of dermatologists already make to patents,\\\" says Zeichner, but he adds that there's catch. \\\"We don't know which antioxidant is making a difference, or if it's a combination of all them. And we don't know what the participants were using as skin care.\\\" That's a biggie, because left to their own devices, people tend to amp up their skin-care routine when they're in a study. Plus, Zeichner points out, \\\"Taking a supplement is not a subsititue for an unhealthy diet. You can't eat lots of sugar and then expect a supplement to balance it out.\\\"\\n\\n\\n\\nAnd that brings us to the next bit of news. \\\"Women live longer than men. One theory is that it's because women lose iron each month during menstruation, and high levels of iron are toxic to the body,\\\" says Zeichner. Now [there's new evidence to suggest](http://www.ncbi.nlm.nih.gov/pubmed/23866012) that iron may interfere with skin's ability to protect itself against free radicals. \\\"Lowering your iron intake may prevent a variety of skin aging, including wrinkles,\\\" says Zeihcner. \\\"So a diet that's really high in red meat could influence skin *and* life expectancy. Vegetarians may have it right.\\\"\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n  __RELATED LINKS:__\\n\\n\\n\\n\\n\\n\\n\\n  \u2022[I'll Have the Salmon (and Maybe Fewer Zits), Please](http://www.allure.com/beauty-trends/blogs/daily-beauty-reporter/2013/06/does-eating-fish-prevent-acne.html)\\n\\n\\n\\n\\n\\n\\n\\n  \u2022[Do Gluten-, Dairy-, and Sugar-Free Diets Work?](http://www.allure.com/beauty-trends/health/2013/gluten-free-dairy-free-sugar-free-paleo-diets)\\n\\n\\n\\n\\n\\n\\n\\n  \u2022[11 Simple Ways to Beat Bloat](http://www.allure.com/beauty-trends/health/2013/how-to-get-rid-of-bloating\\\\#intro)\\n\\n\\n\\n__PHOTO CREDIT: MIKE LORRIG__"^^<http://www.w3.org/2001/XMLSchema#string>
