The Calorie and Macronutrient Breakdown of a Small Ear of Corn
When counting calories, understanding the baseline for a small ear of corn is the first step. Based on data compiled by the USDA, a small ear, measuring between 5.5 and 6.5 inches, provides about 63 calories. The majority of these calories come from carbohydrates, which serve as the body's primary energy source. Beyond its energy content, corn also offers a valuable mix of other macronutrients, including some protein and a small amount of fat. Specifically, a small ear typically provides around 2.4 grams of protein and just 1 gram of fat, with only 0.2 grams being saturated fat. It is also a good source of dietary fiber, which aids in digestion and helps promote feelings of fullness.
Raw vs. Cooked: Does Preparation Change the Calories?
The method of preparation is a crucial factor that affects the final calorie count of your corn. A plain, boiled or steamed ear of corn will have the same low-calorie count as it does raw. The heat itself doesn't add any caloric value. However, the additions made during cooking can dramatically increase the total. To keep the calorie count low, consider steaming or grilling the corn without added fats.
For example, while boiling sweet corn is a common and simple method, grilling can offer a different flavor profile without significant calorie changes, as long as you avoid slathering it in high-calorie sauces. The key is to be mindful of what you add to your corn, not the cooking method itself.
Comparison of Corn Sizes and Calories
To put the small ear's calorie count into perspective, it's helpful to compare it with other standard sizes. The calorie content scales up predictably with the size of the ear.
| Corn Size (Length) | Approximate Calories | Approximate Protein | Approximate Fiber |
|---|---|---|---|
| Small (5.5"-6.5") | 63 kcal | 2.4 g | 1.5 g |
| Medium (6.75"-7.5") | 88 kcal | 3.3 g | 2.0 g |
| Large (7.75"-9") | 123 kcal | 4.7 g | 2.9 g |
The Impact of Toppings on Calorie Count
While a plain small ear of corn is a low-calorie choice, the toppings are where the hidden calories often lie. These popular additions can quickly transform a healthy side into a calorie-dense dish. A tablespoon of unsalted butter can add over 100 calories, while a pat of butter adds about 36 calories. Here are some common toppings and their caloric impact:
- Butter: A single tablespoon adds over 100 calories.
- Oil: A drizzle of olive oil, while a healthier fat, still adds significant calories (about 120 per tablespoon).
- Cheese: Grated Parmesan or cojita cheese adds flavor and calories (about 22 calories per tablespoon).
- Mayonnaise: Used in Mexican street corn (elote), mayo adds substantial calories and fat.
- Cream: Adding cream, sour cream, or creamy sauces will increase the caloric content significantly.
For a lower-calorie option, try a sprinkle of paprika, chili powder, or a squeeze of lime juice instead of rich, fatty toppings. The key is moderation or substitution to maintain the health benefits.
The Health Benefits of Corn Beyond Calories
Beyond its calorie count, corn offers a rich nutritional profile that contributes to overall health. It is packed with several important vitamins and minerals, making it a valuable addition to a balanced diet.
- Vitamins: Corn is a good source of B vitamins, particularly thiamin (B1), pantothenic acid (B5), and folate, which are crucial for energy metabolism and cell function.
- Minerals: It contains beneficial minerals like potassium, magnesium, and phosphorus, which are important for heart health and bone strength.
- Antioxidants: Sweet corn is particularly rich in the antioxidants lutein and zeaxanthin, which are known to support eye health.
- Fiber: The insoluble fiber in corn aids in digestion and helps regulate blood sugar levels.

Conclusion
In summary, a single small ear of corn is a low-calorie, nutritious choice, providing approximately 63 calories primarily from carbohydrates, along with beneficial fiber, protein, vitamins, and minerals. However, its ultimate caloric impact on your diet is heavily influenced by how you prepare it. To keep it a healthy and light option, enjoy it steamed or grilled with minimal additions. By being mindful of toppings, you can enjoy all the natural goodness of corn without significantly increasing your calorie intake. Remember that portion size is key, and integrating corn as a whole, unprocessed food can be a positive step toward a healthier diet.
