Where did you get it? Most of the info I've found lists values per weight, not cup. Or they list it by "serving" which is based on the restaurant.
One serving of popcorn shrimp at Popeyes contains 280 cal, 17 g fat, 1 g fiber = 7 pts. It says one serving = 85grams, or about 3 ounces. I'd say the nutrition info is about average for all brands of popcorn shrimp. I just have no idea how many ounces are in a cup, since it won't measure like water.
Hope that helps
