How Many Calories are in Pineapple?

Pineapple is a very healthy snack and a perfect way to scare away the sweet tooth nibbles. For best results and highest nutritional benefit, choose fresh pineapple, not canned or frozen. One cup of diced pineapple contains a measly 74 calories. You should be careful if you are diabetic though, as this is a very high concentration of natural sugars.
