Calorie Breakdown for 180 Grams of Corn
For those tracking their nutritional intake, knowing the precise figures for common serving sizes is key. A 180-gram portion of raw, sweet yellow corn contains around 155 calories. The energy from this serving is distributed across the macronutrients as follows:
- Carbohydrates: Approximately 34 grams (75% of calories)
- Protein: About 6 grams (13% of calories)
- Fat: Around 2 grams (12% of calories)
This balance makes corn a great source of sustained energy, thanks to its high carbohydrate content, while also providing a notable amount of dietary fiber and protein.
How Preparation Affects Calories
The way you prepare your corn can significantly alter the final calorie count. The figures above are for raw corn, but many people enjoy it cooked, grilled, or canned. The key to maintaining a low-calorie profile is to avoid adding high-fat ingredients like butter, oil, or cheese.
- Boiled Corn: Cooking corn in boiling water will not add a significant number of calories. The calorie content will remain very close to the raw figure, though some water-soluble vitamins might be lost in the process.
- Grilled Corn: Similar to boiling, grilling plain corn will not dramatically increase its calories. However, brushing it with oil or butter for flavor will add a substantial amount of fat and calories.
- Canned Corn: Canned corn is slightly different. A 200-gram serving of canned, drained sweet corn contains about 142 calories, translating to roughly 128 calories for a 180-gram portion. While the calorie count is lower, be mindful of the added sodium often found in canned varieties.
Nutritional Benefits Beyond Calories
Beyond its energy value, corn is a nutrient-dense food packed with beneficial vitamins, minerals, and antioxidants.
Key Nutrients in Corn:
- Fiber: Corn is a great source of dietary fiber, especially insoluble fiber, which promotes good digestive health and can help regulate blood sugar levels.
- B Vitamins: It provides several B vitamins, including Thiamine (B1) and Folate (B9), which are vital for metabolism and overall health.
- Antioxidants: Yellow corn is rich in carotenoids like lutein and zeaxanthin. These antioxidants are essential for eye health, protecting against age-related macular degeneration.
- Minerals: Important minerals found in corn include magnesium, potassium, and phosphorus, which play roles in bone health, nerve function, and blood pressure regulation.

The fiber helps increase feelings of fullness, which can lead to consuming fewer calories overall. Additionally, the complex carbohydrates provide a steady release of energy, preventing sharp blood sugar spikes and crashes that can trigger cravings. However, portion control and cooking without excessive fats are crucial for managing calorie intake.
