Nutritional Powerhouse or Empty Calories?
Corn on the cob is a good source of several essential nutrients, including:

Calorie Considerations
While corn on the cob is nutrient-dense, it is also relatively high in calories. A medium-sized ear contains about 160 calories, primarily from carbohydrates. This makes it important to consume corn in moderation, especially if you are watching your weight.

Downsides of Corn on the Cob
While corn on the cob has nutritional value, there are also some potential downsides to consider:
