Sticky corn, also known as glutinous or waxy corn, is a unique variety of maize with a distinct texture. Unlike sweet corn, which has a high sugar content, sticky corn is rich in a specific type of starch called amylopectin, which gives it its chewy, glutinous consistency. This difference in composition is the primary reason for its higher calorie and carbohydrate content. For a typical ear of medium to large sticky corn, the calorie count generally falls within the range of 260 to 340 calories.
Understanding the Core Nutrition of Sticky Corn
The calories in sticky corn come primarily from its high carbohydrate content. A single serving can contain around 50 grams of carbohydrates, which is significantly more than an equivalent serving of sweet corn. Beyond the carbohydrates, sticky corn also offers a solid nutritional profile that includes protein, fiber, and essential minerals.
- Macronutrient Breakdown: While the exact figures can vary by specific variety and size, a typical 320g ear of sticky corn provides roughly:
- Carbohydrates: 50-65g (high in complex starches)
- Protein: 8-10g
- Fat: 2-3g
- Key Vitamins and Minerals: Sticky corn is a valuable source of B vitamins, including Thiamin (B1), and minerals like magnesium, potassium, and phosphorus. Purple varieties are particularly rich in anthocyanins, potent antioxidants that can help reduce inflammation.
- Dietary Fiber: With about 8g of dietary fiber per ear, sticky corn aids in digestion and can help regulate blood sugar levels, mitigating the impact of its high starch content.
Factors Influencing the Calorie Count
The final calorie count of your sticky corn is not fixed; it depends on several key factors:
- Size and Weight: This is the most obvious factor. A larger ear of corn will contain more kernels and, therefore, more calories. Packaged waxy corn products can range from 200g to 320g or more per ear. For instance, a 200g ear might be around 179 kcal (per 100g), but a larger 320g ear could easily exceed 300 calories.
- Preparation Method and Additives: The way you prepare sticky corn can dramatically alter its final calorie count. A simple boiled or steamed ear is the lowest-calorie option, but adding ingredients changes this:
- Butter and Salt: The traditional addition of butter and salt can add significant fat and calories.
- Grilling: Brushing with oil or butter before grilling increases the calorie density.
- Glazes and Sauces: Sweet and sticky sauces, often made with honey, coconut milk, or sugar, can transform the corn into a high-calorie dessert.
- Variety: While all sticky corn varieties share a high starch content, slight variations in genetics and growing conditions can influence the final macronutrient profile.
Sticky Corn vs. Other Corn Varieties: A Nutritional Comparison
To better understand sticky corn's place in a diet, it's helpful to compare it to its more common counterparts, sweet corn and field corn (desi bhutta). The difference in starch, sugar, and fiber content is key for those watching their carbohydrate or calorie intake.
| Nutritional Aspect | Sticky (Waxy) Corn (per ear) | Sweet Corn (per medium ear) | Desi Bhutta (Field Corn) (per ear) |
|---|---|---|---|
| Calories | 260-340+ | ~90 | Comparable to sticky corn, but more fiber |
| Carbohydrates | High (50g+) | Lower (~19g) | High and complex |
| Fiber | High (8g) | Lower (~2g) | Highest, very fibrous |
| Sugar | Very Low | High (~6g) | Very Low |
| Starch | Very High (Amylopectin) | Lower, partly sugar | High and complex |
| Glycemic Index | Moderate | Low | Low |
As the table illustrates, sticky corn is a carbohydrate-dense food, making it a powerful energy source. Sweet corn offers fewer calories and a sweeter taste due to its higher sugar content, while traditional field corn is valued for its high fiber content and even lower glycemic impact.
Sticky Corn's Place in a Balanced Diet
Despite its higher calorie count, sticky corn can absolutely be part of a healthy and balanced diet. The key is moderation and mindful preparation. Its complex carbohydrates and high fiber provide sustained energy and can help with feelings of fullness, which can be beneficial for managing appetite.
- For Dieters: If you are counting calories, it's wise to be mindful of serving sizes. Consider eating half an ear or preparing it simply, without high-calorie add-ons. Pair it with protein and vegetables to create a more balanced meal.
- For Energy: The high starch content makes it an excellent source of energy, making it a great snack for athletes or anyone needing a quick boost.
- Antioxidant Boost: Choosing a purple sticky corn variety adds anthocyanins, which contribute beneficial antioxidant properties to your diet.
Conclusion: Making Informed Nutritional Choices
In summary, one sticky corn typically contains between 260 and 340 calories, primarily from its high starch content. However, this figure is highly variable depending on its size, variety, and cooking method. While it is more calorie-dense than sweet corn, sticky corn provides a good amount of protein, fiber, and essential minerals, making it a nutritious addition to a balanced diet when consumed in moderation. For the healthiest option, enjoy it steamed or boiled with minimal seasoning to savor its natural, earthy flavor without the added calories from fats or sugars.

Frequently Asked Questions
Can people with diabetes eat sticky corn?
Yes, but in moderation and with careful portion control. Because of its higher starch content, sticky corn has a moderate glycemic index, and its carbohydrates should be factored into your daily carbohydrate intake.
Why does sticky corn have a higher calorie count than sweet corn?
Sticky corn contains a different type of starch called amylopectin in higher concentrations. This complex carbohydrate structure contributes more calories per ear than the simpler sugars found in sweet corn.
Is sticky corn better or worse than sweet corn for weight loss?
Generally, sweet corn is better for weight loss because it contains fewer calories per serving. However, sticky corn’s higher fiber and complex carbohydrate content can provide sustained energy and promote fullness, which can help manage appetite.
Does boiling sticky corn change its calorie content?
No, boiling itself does not add or remove calories from the corn. The calorie count only increases when high-calorie additions, like butter, sauces, or glazes, are applied after cooking.
What are the main nutritional benefits of sticky corn?
Sticky corn is a good source of dietary fiber, which aids digestion, and contains essential vitamins and minerals like B vitamins, magnesium, and potassium. Certain pigmented varieties also offer antioxidants.
Are the calories for fresh and frozen sticky corn different?
No, fresh and frozen sticky corn typically have a similar calorie and nutritional profile, provided the frozen version does not contain any added sauces, salt, or sugar. The flash-freezing process preserves the corn’s nutrients.
What is a healthy way to prepare sticky corn?
To keep it healthy, opt for preparation methods like boiling, steaming, or grilling without excessive oil or butter. Simple seasonings like a sprinkle of salt, herbs, chili powder, or a squeeze of lime juice can add flavor without a high-calorie cost.
