Demystifying the Calories in Boiled Sweet Corn
When it comes to healthy eating, understanding the nutritional value of your food is crucial. For many, sweet corn is a summertime staple, often enjoyed simply boiled on the cob. But for those counting calories or managing their intake, knowing the numbers is important. The calorie count for one boiled ear of sweet corn is relatively low, but the exact figure depends on its size and any added toppings.
A medium ear of corn, measuring around 6.75 to 7.5 inches long, contains about 88 to 100 calories when cooked without any additions. A smaller ear (5.5 to 6.5 inches) has fewer calories, at around 63, while a large one (7.75 to 9 inches) can contain up to 123 calories. This makes boiled sweet corn a versatile and low-calorie option, especially when compared to many processed snack foods.
The Nutritional Breakdown of Sweet Corn
Beyond just calories, sweet corn offers a robust nutritional profile. A single medium ear provides a range of macronutrients, vitamins, and minerals that contribute to overall health. It’s a good source of carbohydrates, fiber, and protein, all of which are essential for a balanced diet.
- Macronutrients: A medium boiled ear of sweet corn contains approximately 21.6g of carbohydrates, 3.5g of protein, and 1.5g of fat. The majority of its fat content is polyunsaturated, which is a heart-healthy fat.
- Fiber: Sweet corn is particularly rich in dietary fiber, including both soluble and insoluble types. The insoluble fiber is what gives the kernels their tough outer shell, which famously passes through the digestive system intact. This bulk-forming fiber aids in digestion and helps with regularity.
- Vitamins and Minerals: This vibrant vegetable is a great source of B vitamins like thiamine (B1) and folate (B9), which are crucial for energy metabolism and cell development. It also contains vitamins A and C, as well as minerals such as potassium, magnesium, and phosphorus.
- Antioxidants: Sweet corn boasts a high concentration of antioxidants, notably lutein and zeaxanthin, which are particularly beneficial for eye health.
The Health Benefits of Including Boiled Corn in Your Diet
Incorporating boiled sweet corn into your diet can lead to several health advantages. Its combination of fiber, vitamins, and other nutrients makes it a valuable addition to a balanced eating plan.
- Digestive Health: The fiber content in corn promotes healthy digestion by supporting a healthy gut microbiome and preventing constipation.
- Weight Management: With its high fiber and water content, corn can help you feel full and satisfied, which may reduce overall calorie intake and assist with weight management.
- Eye Health: The powerful antioxidants lutein and zeaxanthin help protect your eyes from blue light damage and may reduce the risk of age-related macular degeneration.
- Energy Boost: As a starchy vegetable, corn provides a sustainable source of energy, fueling your body and brain throughout the day.
- Heart Health: The potassium, folate, and other nutrients in corn can contribute to a healthy heart by helping to regulate blood pressure and cholesterol levels.
Mindful Corn Consumption: Toppings and Preparation
While boiled sweet corn is naturally low in fat and calories, what you add to it can drastically change its nutritional impact. A pat of butter, a sprinkle of salt, or a drizzle of oil can increase the calorie count and alter the overall health profile. For a healthier option, consider flavor enhancers like a squeeze of lime juice, a sprinkle of paprika, or fresh herbs instead of saturated fats.
Whole, fresh corn is always the healthiest option, but frozen and canned corn can also be nutritious choices. When selecting canned corn, look for varieties with no added salt or sugar to keep your intake in check.
Comparing Cooking Methods: Boiled vs. Grilled Sweet Corn
The way you prepare corn can affect its flavor, but its inherent calorie count doesn't change much unless high-calorie additives are used. Both boiling and grilling are excellent low-calorie cooking methods that preserve most of the corn's nutritional value.

|---|---|---|
| Calorie Count (medium ear) | ~99 calories | ~96 calories |
| Fat Content | Very low (1.5g per medium ear) | Very low (1.3g per 100g) |
| Flavor Profile | Subtly sweet and tender | Smoky and slightly caramelized |
| Nutrient Retention | Retains most nutrients well | Retains most nutrients well |
| Healthiest Preparation | With no additions or minimal salt | With no additions or light seasoning |
