How Many Calories Are in an Ear of Corn?

One ear of sweet corn has approximately 59 calories after it is boiled and drained, according to Calorie King. Only four of these calories are from fat.

An ear of sweet corn has just 0.5 gram of fat with less than 0.1 gram of saturated fat, and it boasts just 3 milligrams of sodium. It has 14.1 grams of carbohydrates and 1.3 grams of dietary fiber, which both translate to approximately 5 percent of a person’s recommended daily intake. Sweet corn is a cholesterol-free food, and it also includes 2 grams of protein, 1.9 milligrams of calcium and 158.1 milligrams of potassium. This nutrition information only refers to the edible part of the corn with the cob discarded.

Sweet corn is a healthy food choice that includes the phytochemicals zeaxanthin and lutein, which are known to promote healthy eyesight. It also offers a good dose of antioxidant activity that increases when the corn is cooked. Although GMO corn is a concern for some, very little sweet corn is genetically modified as opposed to field corn.

For a healthy meal, corn should be lightly salted and served with lime juice or a few drops of olive oil rather than butter, which is high in both fat and cholesterol. You can also sprinkle it with Parmesan cheese or the seasoning of your choice for a boost of healthy flavor.
