Over the past decade or so, there has been a great deal of research regarding the potential health benefits to drinking coffee. The latest study indicates that coffee could actually help those who study from a common skin condition.
Researchers out of Brown University conducted a recent study in an attempt to find a correlation between dietary habits and rosacea. Rosacea, of course, is a common skin condition that affects blood vessels in the face in a way that produces redness and, occasionally, acne-like bumps.
In this study, the researchers looked at 83,000 women enrolled in the national nurse’s study between 1991 and 2005. This group took information on their daily coffee consumption, every four years, and compared this against 5,000 cases of rosacea (as diagnosed by a clinician).
When the research team analyzed the results, they found that women who had consumed at least four cups of coffee per day had a 23 percent lower chance of developing the skin disorder versus those women who had no more than one cup in a one-month period.
The study authors comment, “We found that caffeine intake from coffee but not from other foods (tea, soda, and chocolate) was associated with a decreased risk of incident rosacea in a dose-dependent manner.”
It is important to include that the analysts showed these results conflicted greatly with existing research. However, the researchers state that this new study is actually the first of its kind to evaluate the correlation between coffee consumption, caffeine intake, and rosacea risk in this size a cohort of women.
Now, the team reminds that it is still not clear why this link between coffee and [lower] rosacea risk. Until they have conclusive evidence, the analysts hypothesize that caffeine does have a positive effect on blood vessels and the immune system. They also suggest that caffeine’s already known antioxidant agents and immunosuppressant effects might result in decreased inflammation [in rosacea].
Of course, now they need to begin new studies to further investigate the mechanisms of the actions of all the correlations. The team hopes to replicate the findings, no, among other populations and to further explore caffeine’s relationship with the various rosacea subtypes.
The study has been published in the journal JAMA Dermatology.
