Best Diet for Healthier Skin | Eat Healthy Fats Like Nuts, Seeds, and Avocado

  Not all fats are evil. Omega-3 fatty acids are just one example of healthy fats — and they’re especially important for those who want to prevent fine lines and wrinkles. “Omega-3 fatty acids reduce inflammation that can lead to wrinkles, and they prevent collagen breakdown,” says Keri Glassman, RD, a nutritionist based in New York City. Good sources of these fats recommended by the National Institutes of Health include things like walnuts and flaxseed.

You can also enlist the help of avocados, which are packed with nutrients that benefit the skin. “Avocados are high in sterolins, which help soften and moisturize the skin,” says Glassman. “They also have vitamin E, which enhances the skin’s collagen production while sealing in vital moisture.”

Collagen is a fibrous protein naturally produced in the body that helps repair connective tissue, and keeps our hair, nails, and skin strong, says Zeichner. Eating food rich in vitamins A and C, like blueberries and kale, has also been shown to increase collagen production, according to research.
