Tomatoes: Tomatoes get their red hue from lycopene, a carotenoid that may help to keep your skin smooth. In a study published in 2008 in the European Journal of Pharmaceutics and Biopharmaceutics, researchers found that of the 20 individuals studied, those who had higher skin concentrations of lycopene had smoother skin. Boost your lycopene intake with fresh summer produce like watermelon and carrots too. (Find tomato recipe ideas here.)
Tofu: Tofu and other soyfoods, such as edamame and soymilk, may help to preserve skin-firming collagen because they are rich in isoflavones. In a study published in the Journal of the American College of Nutrition, mice fed isoflavones and exposed to ultraviolet radiation had fewer wrinkles and smoother skin than mice that were exposed to UV light but didn’t get isoflavones. The researchers believe that isoflavones help prevent collagen breakdown. (Find tasty 30-minute dinners using tofu here.)
Tuna: Eating tuna—and other omega-3-rich fish, such as salmon, sardines and trout—may help keep your skin looking youthful thanks to the omega-3 fat EPA (eicosapentaenoic acid). EPA has been shown to preserve collagen. (Enjoy tuna in Mediterranean Tuna Antipasto Salad and more healthy tuna recipes here.)
