Walnuts

Walnuts contain a number of characteristics that make them an ideal diet for maintaining skin health. They're a good source of vital fatty acids, which your body can't produce on its own.

In fact, they contain more omega-3 and omega-6 fatty acids than most other nuts. Inflammation, particularly inflammatory skin conditions like psoriasis, can be worsened by a diet high in omega-6 fats. Omega-3 fats, on the other hand, decrease inflammation in your body, including your skin. Omega-6 fatty acids are rich in the Western diet, whereas omega-3 fatty acid sources are scarce. Walnuts may help fight the inflammatory response to excessive omega-6 since they have a healthy ratio of these fatty acids. Walnuts also include additional nutrients that your skin requires to function properly and stay healthy. Walnuts contain 8% of the daily value for zinc in one ounce (28 grams). Zinc is required for your skin's barrier function to work properly. It's also required for wound healing as well as the fight against infections and inflammation. Walnuts are also high in the antioxidants vitamin E and selenium, as well as 4–5 grams of protein per ounce (28 grams).
