According to Dr. Elizabeth Jeffery, a nutritionist at the University of Illinois (USA), a diet rich in antioxidants can help reduce oxidative stress, thereby facilitating the protection of collagen and elastin fibers in the skin. She emphasized that natural foods rich in plant pigments bring more benefits than just relying on supplements.
Besides anthocyanins, many purple foods also contain vitamin C, manganese and polyphenols, nutrients that participate in collagen synthesis, helping to firm the skin and support blood vessel health. For example, blueberries and purple grapes are considered a rich source of antioxidants, while purple sweet potatoes also supplement fiber and vitamins that are beneficial for the digestive system.
However, experts also note that no food can "miraculously regenerate collagen" in just a short time. Efficiency is only achieved when combining a diverse diet with getting enough sleep, limiting refined sugar, avoiding smoking and protecting the skin from UV rays.
Adding purple foods to your daily diet is a simple but scientific choice, contributing to supporting natural collagen production, slowing down the aging process and improving overall health.
