If you've noticed that what you eat affects not only your waistline but also your skin, hair and nails, you are not alone.
There is even a specialty within the nutrition industry for helping people heal themselves from the inside out: Beauty nutrition.
“The most important thing you can do is eat foods that feed your features with optimal nutrition," said Lisa Drayer, a New York City-based registered dietitian nutritionist who specializes in beauty nutrition. “You can use all the moisturizer and makeup you want, but unless your features are getting the nutrients you need, you’re not going to look your best.”
Drayer wrote the book on the subject.
In “The Beauty Diet: Looking Great Has Never Been So Delicious,” she lays out the best foods to eat to make your skin, hair and nails strong and glowing.
“It’s an anti-aging approach to eating,” she said. “You’re not only helping yourself today but for weeks, months and years to come.”
Drayer said you can see expect to see changes in your skin in about a month once you incorporate the right foods into your diet. For hair and nails, it can take a few months to see changes. The life cycles of the skin, hair and nails vary from one month, three months, and six to 12 months, respectively.
Drayer says her clients who upgrade their nutrition walk away with not just better skin, but improved energy and overall health too.
"It's really amazing to see," she said. "As people are increasingly looking for natural ways to age gracefully, the notion of beauty and nutrition together continues to grow and gain in popularity."
While eating a wide variety of foods is key to an anti-aging diet, there is one food category that Drayer recommends steering clear of: Sugary foods, like candy, cookies, cake and sugar-sweetened beverages.
Sugar-rich foods may contribute to acne and wrinkles, according to Drayer.
"When blood sugar levels are high as a result of eating these foods, sugars can attach to proteins in collagen and they can produce compounds that cause skin to sag and become wrinkled," she said. "Also, when you eat too many refined, sugary carbs, your body makes more insulin, which increases production of hormones known as androgens."
High levels of androgens can lead to pimples, Drayer explained.
Daily intake of added sugars should be no more than 10 percent of your total calories, or 150 calories on a 1,500 calorie diet, according to Drayer.
She also recommends limiting sodium -- found in salty snacks as well as processed, canned and frozen foods and condiments -- to less than 2,300 mg of sodium per day, or about 1 teaspoon of salt, for optimal skin health.
What can you eat to improve your skin?
Drayer recommends these 10 foods.
