If the intake of tyrosine is less, there will be less basic substances for synthesizing melanin, and the skin will turn white. So eat less food rich in tyrosine, such as potatoes and sweet potatoes.
2. Eat more foods rich in vitamin C ... Chemical experiments have proved that a series of reactions formed by melanin are mostly oxidation reactions, but after adding vitamin C, the formation of melanin can be blocked. Therefore, eat more foods rich in vitamin C, such as jujube, fresh jujube, tomato, Rosa roxburghii, orange and fresh green leafy vegetables.
3. Pay attention to foods rich in vitamin E ... Modern scientific research has proved that vitamin E is an antioxidant in human body, especially in fat, and can inhibit the peroxidation of unstable compounds such as unsaturated fatty acids. Lipoprotein in human body is a peroxide of unsaturated fatty acids. Vitamin E can inhibit their peroxidation, thus effectively resisting the deposition of lipofuscin on the skin and keeping the skin fair. At the same time, vitamin E also has anti-aging effect. Foods rich in vitamin E include Chinese cabbage, cauliflower, sesame oil, sesame, sunflower seed, rapeseed oil, sunflower seed oil and so on.
