Mandolinn speaks true, 1 serving may be ONE CUP, but I don't think that's the size of the bags. Minibags are generally 5-6 cups. From what I can tell, she's right, the Act II MINI BAGS do have 210 calories (I looked it up on calorieking)

According to that link above (from calorieking, which may get deleted) 55% of those calories come from fat, so it's not necessarily the best choice if you're trying to eat low fat.
