Yes there are statistics on the beans. If you look through a microscope you will find that nanotechnologists have carefully engraved each bean with figures on the amount of methane gas each bean is likely to generate in the intestine of the consumer and the percentage increase in methane this will contribute to the atmosphere.
its a fallacy that Heinz bake thier beans if fact the are cooked by super heating them with steam we should all sue Heinz under the trades description act I am sure that the pillocks in the EU have a law against this flagrant mis advertising
I actually saw a program on how they manufactured baked beans- although I cannot remember the process well- I do remeber being mildy impressed at the way they remove 'bad' baked beans from the process- a lazer!! The beans are scanned as they fall from one conveyor to another and any that are dodgy get zapped to containers either side of the belts - (so that's where asda smartprice goods come from!)
