Subway's Footlong Cookie

Subway's Footlong Cookie is the #10 worst fast food item, an 810-calorie dessert that completely undermines the chain's healthy positioning. At 50 grams of sugar and 48 grams of fat, it contains more sugar than the average fast food milk shake, yet is marketed as a side to a sandwich. The sheer size—12 inches long and 1 inch thick—means you're consuming 30% more calories than a typical fast food chocolate chip cookie order from rivals like McDonald's. Unlike the Jack in the Box Tiny Tacos, which at least offer savory contrast, this cookie is a one-note assault of excessive sweetness. It costs $3.49, making it 20% pricier per calorie than Subway's own sandwiches, a stark reminder of how the chain's health halo is betrayed by its worst menu offering.
