This study is not a general condemnation of fish oil, but it is very clear on the real danger of combining polyunsaturated fats with alcohol. Paul Jaminet covered this a while ago:

quote from the article:
"For Perfect Health Dieters, perhaps on salmon days alcohol should be limited to a single glass of wine. In general, however, moderate drinking should hold no concern.
Oh, and for you alcoholics, a little friendly advice: If you value your liver, remove polyunsaturated fats from your diet. The safest foods? Red meats and seafood; starches (rice, sweet potatoes, potatoes); vegetables; butter/cream and coconut oil."
