Edamame: Collagen—the fibrous protein that keeps skin firm, youthful-looking and wrinkle-free—begins to decline starting in your twenties! Eating edamame and other soyfoods may help to preserve skin-firming collagen because it is 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.
Other food solutions: Sardines. EPA (eicosapentaenoic acid), one of the omega-3 fats in fatty fish like sardines, has also been shown to preserve collagen.
