4. Fish and seafood
An international study published in the Journal of the American College of Nutrition found that people who ate diets high in fish and seafood had less skin wrinkling. That might be because the omega-3 fatty acids found in fish and seafood slow down the wrinkling process. Wrinkle development is rooted in inflammation, says Logan. “Inflammatory chemicals are essentially like acid rain on the collagen of your skin. Omega-3s turn down the dial on the production of these chemicals,” he explains.
Omega-3s can also help combat acne in a similar way. “Acne spots can look red and are often warmer to the touch, a clear sign of inflammation,” says Koo. “Furthermore, omega-3 fatty acids have mood-regulating benefits, which can help with the stress component of having acne.” He recommends that acne sufferers consume four to five servings of oily fish per week in order to treat the condition. If you can’t imagine eating that much fish every week, Koo suggests taking fish oil supplements instead.
5. Brown rice
Check the packaging of your skin products and you’re likely to see ceramides in the list of ingredients. These lipid molecules, which help your skin maintain its moisture, can also be found in foods such as brown rice. When you eat naturally occurring ceramides, they get incorporated into the outer layer of your skin and help it maintain its hydration, says Logan. “There are clinical studies that showing that ceramides [you eat] significantly improve hydration.
