Foods that promote healthy skin include those rich in antioxidants, vitamins, and healthy fats. Berries, avocados, nuts, and fatty fish, such as salmon, provide essential nutrients that support skin hydration and elasticity. Foods high in vitamin C, like citrus fruits and bell peppers, are vital for collagen production, while vitamin E found in nuts and seeds helps protect the skin from oxidative stress. Maintaining a balanced diet with these food groups can enhance overall skin health and appearance.
