What you put on your plate might affect what you see in the mirror. But a few tweaks to your dining habits can go a long way to keeping your skin youthful and your body healthy.
The key approach? Eat better.
"Poor-quality foods, like trans fats, cause inflammation -- and aging is basically a chronic inflammatory state," says Timothy Harlan, MD. He's assistant professor of medicine at Tulane University School of Medicine. "Can you look older because you're eating crap? Absolutely."
For example, eating too much sugar and processed carbohydrates (like pasta, bread, and baked goods) can lead to damage in your skin's collagen, which keeps your skin springy and resists wrinkles, says Andrea Giancoli, MPH, RD. She's a policy analyst for Beach Cities Health District.
What's more, these foods put your overall health on the line. They are tied to diseases like heart disease and diabetes, she says.
Other foods, like fruits and vegetables, are good for your skin.
