Ultraviolet rays not only increase skin melanin, causing freckles and age spots, but in severe cases, they can also gradually affect the dermis. Typically, starting around April, outdoor UV rays begin to gradually intensify, so sun protection is not just a summer concern. In addition to sunscreen and umbrellas, some foods can also help you resist spring UV rays.
1 Strawberry
The polyphenols found in berry fruits like strawberries inhibit tyrosinase, which promotes melanin production. Furthermore, reactive oxygen species generated by UV radiation damage cell membranes and DNA within cells, turning lipids into peroxidized lipids, which is a cause of blood thickening. The polyphenols in berry fruits also play an important role in inhibiting the formation of peroxidized lipids and preventing blood thickening.
2 Apple
The apple peel is rich in "apple polyphenols," which contain chlorogenic acid, catechins, and anthocyanins, possessing powerful antioxidant effects. Utilizing the antioxidant action of "apple polyphenols" to combat the damage caused by reactive oxygen species generated after UV exposure protects beautiful skin. Additionally, it also has a certain effect on melanin production and skin whitening.
3 Tomato
The lycopene abundant in tomatoes not only has antioxidant effects but also plays a role in reducing UV-induced spots and skin roughness. According to research by Kagome Co., Ltd. of Japan, lycopene is retained in the skin and becomes effective. It can be called "edible sunscreen." Heating with oil can improve the absorption efficiency of lycopene, so it is recommended to add some olive oil to cooked tomato juice or canned tomatoes.
4 West Indian Cherry Juice
The Vitamin C content in West Indian cherries is 17 times that of lemons. Moreover, it also contains anthocyanins, which, together with Vitamin C, provide a dual weapon for removing reactive oxygen species. However, since both Vitamin C and anthocyanins cannot be stored in the body, they need to be replenished frequently.
5 Coffee
Coffee is rich in polyphenolic substances such as chlorogenic acid and tannic acid. According to a study by Professor Kondo at Ochanomizu University in Japan, people who habitually drink coffee have fewer spots. It is believed that the chlorogenic acid in coffee inhibits melanin production. The polyphenol content in one cup of coffee is twice that of green tea, so drinking coffee allows for more efficient intake of polyphenols.
