Corn, one of the most widely consumed grains globally, is a staple in many cuisines due to its versatility and nutritional benefits. Whether it’s boiled, grilled, or added to a variety of dishes, corn is a favorite among many for its sweet taste and satisfying crunch. However, for those watching their diet or managing their calorie intake, understanding the nutritional value of corn, particularly the number of calories in a cup, is essential. This article delves into the calorie content of corn, explores its nutritional benefits, and discusses how it can be a valuable addition to a balanced diet.
Understanding Corn and Its Varieties
Before diving into the specifics of calorie content, it’s crucial to understand that corn comes in various forms and types, each with its own nutritional profile. The most common types of corn include sweet corn, popcorn, and field corn, with sweet corn being the variety most commonly consumed fresh.

Nutritional Overview of Sweet Corn
Sweet corn is not only a tasty addition to meals but also packs a punch when it comes to nutrients. It is a good source of carbohydrates, fiber, and several vitamins and minerals such as vitamin C, thiamin, folate, and phosphorus. The fiber content in sweet corn can help with digestion and satiety, making it a beneficial choice for those looking to manage their weight or improve their overall digestive health.
Calorie Content of Sweet Corn
The calorie content of sweet corn can vary depending on the serving size and method of preparation. Generally, a cup of fresh sweet corn kernels is relatively low in calories. According to the United States Department of Agriculture (USDA), one cup of frozen, thawed sweet corn kernels contains about 132 calories, while one cup of canned sweet corn, drained, contains approximately 130 calories. For fresh corn on the cob, the calorie count can vary based on size, but on average, one medium ear of corn (about 3/4 cup kernels) contains around 90 calories.
Factors Affecting Calorie Content
The calorie content in a cup of corn can be influenced by several factors, including the type of corn, its preparation method, and any added ingredients. For instance, if butter, salt, or sugar is added to corn during cooking, the calorie count can significantly increase. Similarly, corn that is deep-fried or cooked in large amounts of oil will have a much higher calorie content compared to boiled or grilled corn.
Comparison of Calorie Content Across Different Preparation Methods
To give a clearer picture, let’s compare the calorie content of corn prepared in different ways:
