Eat saturated fat – not polyunsaturated – to minimise liver damage from alcoholism
Yeah, it’s only a mouse study, but still…

Anyhoo, here’s some extracts from the article:
A primary safety concern with alcohol is its effect on the liver. Alcohol consumption can produce fatty liver disease and, eventually, a scarred and damaged liver (cirrhosis).
Interestingly, in animal studies the harmful effects of alcohol on the liver occur only when it is combined with polyunsaturated fats:
…researchers hailed saturated fat as “a novel treatment for liver disease…
Mice fed 27.5% of calories as alcohol developed severe liver disease and metabolic syndrome when given a corn oil diet, but no disease at all when given a cocoa butter diet. (Corn oil is 55% polyunsaturated, cocoa butter is predominantly saturated fat and is less than 3% polyunsaturated.)
The first line of this paper begins, “The protective effect of dietary saturated fatty acids against the development of alcoholic liver disease has long been known.”
The more saturated fat, the healthier the liver.
Alcohol is metabolized in the liver just like fructose, a toxic sugar. Polyunsaturated fats are chemically fragile and quick to react with sugars; saturated fat, which lacks fragile carbon double bonds, does not.
It seems that if you keep your liver clear of polyunsaturated fats, the alcohol will be disposed of safely.
Mice on a saturated fat diet can get 27.5% of calories as alcohol with no liver damage. In humans, that would correspond to a daily 350 ml (12 fluid ounce) bottle of 80-proof gin, rum, or vodka, or a liter (36 fluid ounces, 1.3 bottles) of red wine.
Drink up, and enjoy a steak with butter.
Edit – 30/Apr/2013: Alcohol-proof your liver. SFAs.
Translation: while a single meal of dark chocolate and coconut oil may not acutely protect the liver from alcohol [tonight], a few days’ worth just might.
Others?
Red meat. While the saturated fat content of red meat is expected to similarly bolster liver resistance to oxidative stress, another component – carnitine (of the recent TMAO infamy) – may also provide some benefit by enhancing liver fat turnover (Kepka et al., 2011 sorry no full text, so only in theory). Taurine, also found in red meat, also prevents some alcohol-induced liver pathologies [in rats] (Kerai et al., 1998 & Pushpakiran et al., 2005).
