Greetings to all coffee lovers! The world will be pleased to learn that a new study has found that the regular gulping of this rich, aromatic beverage from your morning mug could help protect against a deadly type of skin cancer.
You may grab a cup (or two) of coffee every morning to help you wake up and face the day, and might as well, do your skin a favor, as well. Researchers say, that your regular cup of coffee helps you fight against skin cancer.
Individuals in the study who consumed four or more cups of caffeinated coffee were around 20 % less likely to develop malignant melanoma over 10 years,compared to those who don’t drink coffee.
Melanoma is triggered by damage to skin cells’ DNA caused by UV rays from the sun or tanning beds; these mutations prompt the cells to grow abnormally and spread to other tissues in the body, where it can be fatal. But in a report published in the Journal of the National Cancer Institute, Erikka Loftfield from the National Cancer Institute and her colleagues found .
For the investigation, scientists looked at almost half a million retirees who were cancer-free at the start of the study. The researchers tracked the participants for an average of 10.5 years and asked them to report their coffee consumption, alongside various other factors which could also influence their risk of developing cancer, such as alcohol consumption, smoking, BMI and exercise. To assess how much UV radiation participants were likely exposed to, they used NASA data on the amount of sunlight that their hometowns received.
During the course of the study, 2,904 cases of malignant melanoma were recorded, alongside 1,874 cases of melanoma in situ, which is the very earliest stage of melanoma. After taking all of the variables into consideration, they found that as compared with non-coffee drinkers, those who drank at least four cups of coffee a day had a 20% lower risk of developing malignant melanoma.
They also found that the association only applied to caffeinated coffee, as a lower risk was not identified in those who drank decaf coffee. This could indicate that caffeine is responsible for the possible protective effect, which would support lab-based studies. However, it’s also possible that decaf coffee contains different amounts of other molecules which could be playing a role.
Our results, and some from other recent studies, should provide reassurance to coffee consumers that drinking coffee is not a risky thing to do,” said study researcher Erikka Loftfield, a doctoral student at the Yale School of Public Health and a fellow at the National Cancer Institute.
Although the study can’t prove that coffee truly does protect against skin cancer, the researchers have proposed a few potential mechanisms which could explain the associations observed. It could be that coffee prevents the development of cancer because it prevents DNA damage, or detoxifies carcinogens, which has been observed in cell culture. Furthermore, coffee roasting generates vitamins which have been demonstrated to protect against UV-induced skin cancer in mice.
While the study is certainly interesting, further research is warranted as the investigation was limited. It’s unclear at this stage which ingredient could be exerting these apparent effects.
