There are a few ways you can change your diet to give your body an anti-aging boost with the foods you eat every day.
First, let's look at fats. Adding foods that are full of good-for-you dietary fats and oils can help reduce the appearance of fine lines and wrinkles as well as improve the long-term health of your skin. Omega-3 fatty acids are especially good at plumping and tightening skin, because they nourish skin cells. Oily fish such as salmon, tuna, herring and sardines are good sources of omega-3s, as are almonds, walnuts, flaxseed and sunflower seeds (and oils).
Tuna, salmon, nuts and legumes are all also good sources of two trace minerals important to wrinkle reduction: selenium and copper. Selenium is an antioxidant, which means it helps prevent cell damage by neutralizing free radicals, and it may also help restore skin's elasticity. Copper plays an important role in how the body builds the skin's two skin tissue proteins, elastin and collagen. Soy-based foods may also help build collagen. Whether or not soy foods are beneficial against wrinkles is still up for debate, but soybeans contain plant compounds called isoflavones, some of which have antioxidant properties.
