We didn’t think anything could be worse than Baskin Robbins' 2008 bombshell, the Heath Bar Shake. After all, it had more sugar (266 grams) than 20 bowls of Froot Loops, more calories (2,310) than 11 actual Heath Bars, and more ingredients (73) than you’ll find in most chemist labs. Rather than coming to their senses and removing it from the menu, they did themselves one worse and introduced this caloric catastrophe. It’s soiled with more than a day’s worth of calories and three days worth of saturated fat, and, worst of all, usually takes less than 10 minutes to sip through a straw.For the complete list of the 20 Worst Foods in America 2009, check out these rankings and the best options to eat instead of the gut bombs!
