This little tool over at the BBC calculating the calories of drinks is actually quite handy. I just learned that five pints is the same as a danish, a hot dog, a pizza slice, a couple of onion bhaji and a couple of jaffa cakes. Two doubles of hard liquor are only worth a pizza slice and one jaffa cake.
That seems reasonable and, given that this works as a tool to make sure you do not over eat as you drink, a valuable addition to the web resources we have at our fingertips. By knowing the risks posed by solid food offering only empty calories, you will be in a better position to plan your nutritional intake. Unfortunately it does not calculate the other nutritional qualities of craft real ale like the relative merits of eating two donuts, four onion bhajis and six jaffa cakes a day compared to the two drinks most medical experts recommend you have daily.
