There's so many opinions on that it's extremely hard to get a clear picture. The "optimal" diet currently in vogue seems to be a sort of squirrel diet consisting of soy milk, legumes, nuts, whole grainS, chicken and vegetables while cow milk, red meat, potatoes, sugar and salt is the spawn of the devil.
In a more moderate sense (i.e. My own biased opinion) "eating bad" is what everybody knows deep down: excess of candy, ice cream, soft drinks, fast food or the tendency to over-eat i.e. All-you-can-eat places and too big dinner plates at home :)
