What Are You Feeding Your Skin? 8 Beauty Foods for Healthy Skin

4. Salmon, Walnuts and Flax Seed

These seemingly unrelated foods all deliver essential fatty acids, and thus are key foods for healthy skin. Essential fatty acids are responsible for healthy cell membranes, which is not only what act as barriers to harmful things but also as the passageway for nutrients to cross in and out and for waste products to get in and out of the cell.
Stuart explains that, “Because it is the cell membrane that also holds water in, the stronger that barrier is the better your cells can hold moisture. And that means plumper, younger looking skin.”
The same inflammatory process that can harm our arteries and cause heart disease can harm skin cells. Essential fatty acids can offer protection to both. The best-known essential fatty acids are omega 3 and omega 6, which must be in balance for good health (and good skin). Though we all seem to get enough omega 6, Stuart says many people lack omega 3s. Fish, walnut, and flaxseed oil are among the best sources.
