What you eat affects how your skin ages. People who eat more fresh fruits, vegetables, and protein-rich fish tend to have fewer wrinkles. That's why it's smart to consume an anti-inflammatory diet that includes plenty of whole grains; fruits and vegetables of different hues; omega-3 fatty acids from cold-water fish, walnuts, extra-virgin olive oil, and flaxseed; and antioxidant-rich spices like turmeric, ginger, cumin, and cinnamon. Wash it all down with plenty of water—a minimum of 8 cups per day—to keep your skin hydrated and free of impurities. At the same time, avoid partially hydrogenated oils, trans fats, and polyunsaturated vegetable oils, which are all pro-inflammatory. Foods that cause a rapid rise in blood sugar and insulin—such as sugary or starchy processed foods—can trigger inflammation as well.
