Yes! According to a recent study published in JAMA Dermatology.
Data collected from the Nurses’ Health Study II identified an inverse relationship between caffeinated coffee consumption and rosacea. The more coffee they drank, the better the correlation. Also, decaffeinated coffee did not have this power over rosacea and neither did other caffeine containing food or drinks such as chocolate, tea, soda, etc.
Why might coffee be helpful for rosacea?
Caffeine is a vasoconstrictor and anti-inflammatory. Coffee contains antioxidant polyphenols which have been shown to benefit rosacea. Coffee also has more caffeine than other caffeine-containing food and beverages such as tea and chocolate.
Authors hypothesize that these reasons may be why caffeinated coffee stands out as helpful for rosacea. But, we don’t really know. This study just provides the first observation and correlation.
What’s impressive is that the number of participants in the study was high — 82,737 — meaning, this info comes from a lot of people.
Why is this information about coffee and rosacea new?
We’ve known that hot foods and heat trigger rosacea flares. We lumped all hot drinks together – tea, coffee, chai, a cup of hot soup, etc. We also know that spicy foods, strenuous exercise and sunlight will trigger rosacea flares. These are called “trigger factors.”
Now, we’ve teased out coffee, which has come up to be a winner. It’s hot, but it’s correlated with less incidence of rosacea! I’m drinking my morning cup as I type this, and I’m prone to the erythematotelangiectatic-type of rosacea.
Other factors that might impact a person’s physiology did not negate this helpful effect of caffeinated coffee on rosacea. These include factors such as smoking, alcohol intake, physical activity, or BMI, for example.
