Corn Nutrition Facts Per Serving-Healthy Or Sneaky?
A standard serving of sweet corn nutrition-defined as one medium ear (about 90-100 grams of edible kernels)-contains roughly 86 calories, 19 grams of carbohydrates, 3 grams of protein, 1.5 grams of fat, and 2 grams of fiber, along with essential micronutrients like vitamin C, folate, and potassium. This nutrient profile makes corn a moderate-energy, fiber-containing carbohydrate source that supports digestion and daily energy needs without excessive fat or sugar.
Core Corn Nutrition Facts Per Serving
The corn nutrition facts vary slightly depending on preparation (boiled, grilled, canned), but raw or boiled sweet corn provides a consistent baseline widely cited by the USDA as of 2024. The following values reflect a typical 100-gram edible portion, offering a precise snapshot for meal planning and dietary tracking.
| Nutrient | Amount per 100g | % Daily Value* |
|---|---|---|
| Calories | 86 kcal | 4% |
| Carbohydrates | 19 g | 6% |
| Protein | 3.2 g | 6% |
| Fat | 1.2 g | 2% |
| Fiber | 2.4 g | 9% |
| Sugar | 6.3 g | - |
| Vitamin C | 6.8 mg | 8% |
| Folate | 42 mcg | 10% |
| Potassium | 270 mg | 6% |

Macronutrient Breakdown Explained
The macronutrient composition of corn reveals why it is classified primarily as a starchy vegetable. Approximately 75% of its calories come from carbohydrates, making it a reliable energy source. Protein contributes modestly, while fat remains minimal, making corn suitable for low-fat diets.
- Carbohydrates: Provide quick and sustained energy, especially useful for active individuals.
- Protein: Supports tissue repair but is incomplete, lacking some essential amino acids.
- Fat: Naturally low, making corn heart-friendly when not prepared with added butter or oil.
- Fiber: Aids digestion and supports gut health.
The fiber content in corn, though moderate, plays a crucial role in promoting satiety and reducing spikes in blood sugar when consumed with other whole foods.
Micronutrients That Matter
The vitamin and mineral profile of corn contributes significantly to overall health, especially when consumed as part of a balanced diet. Corn is not just empty calories-it contains antioxidants and essential micronutrients often overlooked.
- Vitamin C: Supports immune function and skin health.
- Folate (Vitamin B9): Critical for DNA synthesis and especially important during pregnancy.
- Potassium: Helps regulate blood pressure and muscle function.
- Lutein and zeaxanthin: Antioxidants linked to eye health.
According to a 2023 European Nutrition Review, diets including lutein-rich vegetables like corn were associated with a 12% lower risk of age-related macular degeneration.
How Serving Size Affects Nutrition
The serving size impact is crucial when evaluating corn's nutritional value. A single ear of corn may seem small but delivers a meaningful portion of daily carbohydrate intake.
- Small ear (70g): ~60 calories, lower carb load.
- Medium ear (90-100g): Standard serving with balanced nutrients.
- Large ear (120g+): Higher calorie and carbohydrate intake.
- Processed corn (canned/creamed): Often contains added sodium or sugar.
The portion control factor becomes especially important for individuals monitoring carbohydrate intake, such as those with diabetes or on low-carb diets.
Fresh vs Processed Corn
The fresh versus processed distinction dramatically affects corn's nutritional profile. While fresh corn retains most nutrients, processed forms may introduce additives that alter health outcomes.
- Fresh corn: Highest in vitamins and antioxidants.
- Frozen corn: Nutritionally comparable, often flash-frozen at peak ripeness.
- Canned corn: May contain added sodium (up to 300 mg per serving).
- Creamed corn: Often includes added sugar and fats.
A 2022 food processing study found that canned vegetable products can contain up to 40% more sodium than their fresh counterparts, making label reading essential.
Health Benefits Backed by Data
The health benefits of corn extend beyond basic nutrition, supported by emerging research in plant-based diets and metabolic health.
- Supports digestion due to fiber content.
- Provides sustained energy for physical activity.
- Contains antioxidants that reduce inflammation.
- May support eye health due to carotenoids.
"Whole grains and starchy vegetables like corn contribute significantly to daily fiber intake, which remains below recommended levels in over 70% of European adults," - European Food Safety Authority report, March 2024.
The antioxidant compounds found in corn, particularly in yellow varieties, are increasingly studied for their protective effects against chronic diseases.
Common Misconceptions About Corn
The corn nutrition myths often stem from confusion between whole corn and processed corn products like corn syrup. Whole corn is nutritionally distinct and far less problematic.
- Myth: Corn is unhealthy. Reality: Whole corn is nutrient-rich.
- Myth: Corn causes weight gain. Reality: Portion size and preparation matter more.
- Myth: Corn has no nutrients. Reality: It contains fiber, vitamins, and antioxidants.
The processed corn derivatives, such as high-fructose corn syrup, are what typically raise health concerns-not whole corn kernels.
