Is corn a starch or vegetable?

Corn is categorized as a starch or starchy vegetable due to its high starch content. One cup of uncooked corn contains 20.5 grams of starch, 28.2 grams of carbohydrates and 120 calories.

According to Georgia State University, starch is a type of carbohydrate that provides energy to the human body. Corn and other starchy vegetables also provide fiber, folate, potassium and vitamins A and C. Since starchy vegetables contain higher amounts of other carbohydrates that raise blood glucose, diabetics should limit their serving size of corn to 1/2 cup and include lean protein, non-starchy vegetables and fruit in each meal.
