It is very high in calorie, yes. One hundred grams of corn is more or less 365 calories. Yikes! It has 74 grams of carbohydrates and 9 grams of protein. Maybe you can eat this food once in a while and at half a serving. Remember that boiled corn is better than salted corn. For this food, less is definitely much better.
White or yellow corn, you ask? Well, the nutrients are not that different and the calories remain the same. Sweet corn, on the other hand, is lesser in calories compared to white or yellow corn. But the nutrients in it are lesser too.
