Laboratory rats have confirmed their place at the pinnacle of evolution: not only do mothers turn down cocaine in order to care for their young, but they even manage to reduce their calorie intake when they're drinking alcohol.
In the current study, UF researchers made alcohol more palatable by adding it to decarbonated, non-alcoholic beer, which also allows scientists to precisely measure the alcohol content. In a separate test they presented the alcohol mixed into a sweet gelatin. (emphasis mine) Both male and female rats cut back on their calories from food and maintained a consistent intake of overall calories during the experiments, even with access to plenty of food, fresh water and palatable alcohol.
Humans were apparently discouraged from participating.
