Frequently Asked Questions

How many calories are in corn on the cob?

A medium ear of corn on the cob (6.75-7.5 inches long) contains approximately 77-90 calories. The calorie count varies based on size and preparation method. Without butter or toppings, plain boiled or grilled corn on the cob is a low-calorie, nutritious vegetable option that provides fiber, vitamins, and minerals while remaining relatively light in calories.

Does corn on the cob have more calories with butter?

Yes, adding butter significantly increases the calorie content of corn on the cob. One tablespoon of butter adds approximately 100 calories, essentially doubling the calorie count from around 90 to 190 calories per ear. For a lower-calorie option, consider using cooking spray, herbs, or a small amount of olive oil instead of butter when preparing corn.

How many calories are in a large ear of corn on the cob?

A large ear of corn on the cob (approximately 8-9 inches long) contains about 110-130 calories when plain. Larger ears naturally contain more kernels and therefore more calories than smaller or medium-sized ears. The calorie content increases proportionally with size, making portion control important for those monitoring their caloric intake.

Is corn on the cob a low-calorie food?

Yes, corn on the cob is considered a relatively low-calorie food when eaten plain. At 77-90 calories per medium ear, it's a filling, nutrient-dense option that provides complex carbohydrates and fiber. However, the calorie count increases significantly when prepared with butter, oil, or high-calorie toppings, so preparation method matters for calorie-conscious consumers.

What allergens are found in corn on the cob?

Corn on the cob is naturally free from major allergens like gluten, dairy, nuts, and soy. However, corn itself can be an allergen for some individuals, though corn allergies are relatively rare. Cross-contamination can occur during processing or preparation. Using an allergy checker app can help identify potential allergens in packaged corn products or restaurant preparations that may contain butter or seasonings.

How many calories are in grilled corn on the cob versus boiled?

Grilled and boiled corn on the cob contain virtually the same calories—approximately 77-90 calories per medium ear—when prepared without added fats. The cooking method itself doesn't significantly change the calorie content. However, grilled corn is often brushed with oil or butter, which can add 40-100 additional calories, while boiled corn is typically served plain or with minimal additions.

Can I track corn on the cob calories using a nutrition calculator?

Yes, nutrition calculators like the Chipotle nutrition calculator and other food tracking apps allow you to calculate calories in corn on the cob accurately. These tools help you account for preparation methods, portion sizes, and added ingredients like butter or seasonings. For restaurant meals, using nutrition info tools ensures accurate calorie tracking and helps identify potential allergens in prepared dishes.

How does corn on the cob fit into a gluten-free diet?

Corn on the cob is naturally gluten-free and safe for people with celiac disease or gluten sensitivity. Fresh corn contains no wheat, barley, or rye proteins. However, be cautious with seasoned or pre-packaged corn products, which may contain gluten-containing additives. Using an allergy checker app can help verify that corn products are truly gluten-free and free from cross-contamination.
