Daily Coffee And Skin Aging – A daily cup of coffee may be aging your skin, according to some doctors, but other research suggests that it can also reduce cancer.
Basal cell carcinoma is the most common form of skin cancer, with nearly one million new cases diagnosed each year in the United States. A diet that contains even a small protective factor may have great public health impact, the researchers said.
“Our study indicates that coffee consumption may be an important option to help prevent basal cell carcinoma,” said lead researcher Fengju Song, a postdoctoral fellow in the department of dermatology at Brigham and Women’s Hospital and Harvard Medical School in Boston. “The amount of caffeine consumption was inversely associated with risk,” Song said, meaning the more coffee consumed, the lower the risk of skin cancer.
Decaffeinated coffee was not associated with a decreased risk of basal cell carcinoma, and the researchers said any protective effect would likely be because of caffeine, a stimulant. The study authors also expressed surprise that coffee did not reduce the risk of two other types of skin cancer, squamous cell carcinoma and the less common but potentially deadly melanoma.
For the study, Song’s team collected data on nearly 113,000 adults — almost 73,000 women who took part in the U.S. Nurses’ Health Study and almost 40,000 men who were part of the Health Professionals Follow-Up Study.
Over more than 20 years of follow-up, more than 25,000 cases of skin cancer were diagnosed among the men and women in the studies. Of these, about 23,000 were basal cell carcinoma, about 2,000 were squamous cell cancer and 741 were melanoma.
The researchers found that women who drank more than three cups of coffee a day had a 20 percent lower risk of developing basal cell carcinoma compared with women who drank less than one cup of coffee in a month.
For men, the risk was 9 percent lower for those who drank three cups of java daily compared with those who drank less than one cup a month, Song’s group noted.
The risk for women who drank the most coffee was lowered 18 percent; for men who downed the most coffee, the risk was reduced 13 percent, Song’s team found.
