Is corn on the cob fattening?

Corn on the cob, if prepared properly, is not fattening, according to HowStuffWorks. Boiled corn on the cob is a complex carbohydrate, which take longer to digest and do not raise blood sugar like simple carbohydrates do.

As long as it is not slathered in butter and other toppings, corn is a very healthy food, explains HowStuffWorks. One medium ear of yellow or white corn has 77 calories and 1 gram of fat. It is high in fiber, with 3 grams per serving. Dietary fiber maintains blood sugar levels, helps create normal bowel movements and lowers cholesterol levels. Corn is a source of several vitamins, including folic acid and vitamin C. Folic acid helps prevent heart disease.
