9. Spinach: Spinach contains various nutrients that are good for your skin. The most useful vitamins of spinach are vitamin A, C, E, and K. The high amount of vitamin A in spinach also promotes healthy skin by allowing for proper moisture retention in the epidermis, thus fighting psoriasis, keratinization, acne and even wrinkles. A study published in the International Journal of Cancer found that folks who ate the most spinach developed half as many skin tumors over 11 years as those who ate the smallest amount. That’s likely because the folate in spinach helps maintain and repair DNA, reducing the likelihood of cancer-cell growth.

7. Strawberries: Strawberries are one of the World’s healthiest foods. Just one cup has over 100 percent of the Recommended Daily Allowance (RDA) for Vitamin C, 20 percent RDA for manganese and nearly 15 percent RDA for fiber. In other words, strawberries are rich in nutrients that our skin loves to dine on. With a high content of alpha-hydroxy acids, strawberries help slough off dead skin cells, increasing natural skin renewal by revealing the new youthful skin underneath. Strawberries also contain ellagic acid, which helps protect the skin from UV rays.

6. Sweet Potatoes: Snacking on sweet potatoes can keep your skin clear, smooth and young-looking. Orange-fleshed sweet potatoes are rich in beta-carotene, an antioxidant that coverts to vitamin A in your body, which is in charge at producing new skin cells and shedding old ones. A regular influx of new cells keeps the surface of your skin smooth, fresh-looking and resistant to irritants and damage. It’s no coincidence that some of the best topical healthy-skin ingredients in beauty products, retinoic acid and retinol, are derivatives of vitamin A.
