Topical or oral use of caffeine has a preventive effect on skin cancer caused by excessive sun exposure, according to a US study.
A study by the university of Washington in Seattle found that drinking one cup of caffeinated coffee a day reduced the risk of skin cancer by 5%, while decaffeinated coffee had no effect.
Although caffeine helps prevent skin cancer, sun protection still needs to be done. Statistics show that the high-risk groups of skin cancer are men aged 50-60 years old, living in inland mountain areas or coastal areas, especially those engaged in open-air work. It is worth reminding that in human life, about 75% of UV exposure is accumulated before the age of 18, especially in childhood.
How to drink the right amount of coffee? Generally speaking, the daily intake of caffeine should not exceed 300 mg. Using the average coffee cup, about three cups of coffee contain 300 milligrams of caffeine. In addition, some foods such as tea, cocoa, chocolate and cola also contain caffeine. Strictly speaking, caffeine should be calculated by quantity. For example, an average of 2 cups of tea contains caffeine equivalent to 1 cup of coffee.
