Hey there! I have a very rudimentary knowledge about calories and I don’t even ponder a lot about it while eating any food item. But, eating popcorn is something which bothers me as I feel that popcorn has lot of calories in it which can be harmful to my health. I may be wrong in what I am saying but i have seen many of my friends who love to eat popcorn and ironically they all are overweight. Can you guys tell me about the exact importance of calories in any food item and also the movie popcorn calories?
