Today I read 3 studies on the Internet regarding psoriasis and alcohol.
The first study was done by doctors at a hospital for people with an alcohol problem. The doctors followed during a number of years 4 patients who also had rather severe psoriasis. The doctors found an amazing correlation between the amount of alcohol consumed and the severity of the psoriasis. If the patients had more alcohol their psoriasis got worse immediately, and vice versa. Conclusion : If you are a heavy drinker and you have psoriasis, you better lower your alcohol consumption (probably also good advice for heavy drinkers who don't have psoriasis).
A second study was about a large group of people with moderate to severe psoriasis. Of these people the alcohol consumption pattern was measured in some scientific way. It turned out that the alcohol consumption pattern for the psoriasis patients was not different from the pattern of the general population. Conclusion : Psoriasis is not caused by alcohol.
Please understand that these two studies do NOT contradict each other.
A third study in some way was like the second study, but differentiated between several types of alcohol. The conclusion of this study was that drinking light beer, red wine, white wine, liquor, ... did not increase one's chance to get psoriasis EXCEPT for heavy beer. Drinking beer of 5% alcohol or more increases the odds of getting psoriasis. The reason may be that heavy beer contains gluten.
By the way : Anyone here who knows a heavy beer that is gluten-free ?
I'm planning to read more about this subject and keep you informed when I find new data.
