The Core Calorie Count
When addressing the question of how many calories are in a raw red bell pepper, the answer is relatively simple and consistently low across various sources. On average, a medium-sized raw red bell pepper (approximately 120-150 grams) contains about 37-39 calories. This makes it a highly calorie-efficient food, offering significant volume and a satisfying crunch with very little energy intake. For those who prefer to measure in smaller increments, 100 grams of raw red bell pepper contains around 26 to 31 calories, depending on the specific ripeness and size. The vast majority of these calories come from carbohydrates, mainly natural sugars like glucose and fructose, and a small amount of fiber.
Nutritional Breakdown Beyond Calories
While the low-calorie count is a major benefit, the true value of a raw red bell pepper lies in its dense nutritional profile. It is a nutritional powerhouse, packed with essential vitamins and antioxidants. A single medium-sized red pepper can provide more than the daily recommended intake of Vitamin C, a powerful antioxidant that supports the immune system, promotes skin health, and aids in iron absorption. It also contains high levels of Vitamin A, in the form of beta-carotene, which is crucial for vision and immune function. The list of beneficial nutrients continues with Vitamin B6, Vitamin K1, Vitamin E, Folate, and various minerals like potassium and manganese. These components work together to provide numerous health benefits, making the red bell pepper a true 'superfood.'
Raw vs. Cooked Bell Pepper
The preparation method can slightly alter the nutritional content and calorie count of a red bell pepper. Raw bell peppers contain the highest levels of Vitamin C, which is heat-sensitive. Roasting, for instance, can reduce the Vitamin C content by up to 25%. However, cooking can also increase the bioavailability of certain antioxidants, such as carotenoids. The calorie count of cooked bell peppers can also change if oil is added during preparation, as this will significantly increase the total energy content. When consumed raw, the bell pepper remains a fat-free, low-calorie option. This distinction is important for those closely monitoring their nutrient intake and food preparation techniques.
Red vs. Green Bell Pepper: A Nutritional Comparison
There is a common misconception that all bell peppers are nutritionally identical, but the truth is that the color indicates different stages of ripeness and, consequently, different nutrient levels. Green bell peppers are less mature than red ones and have a slightly more bitter flavor.
| Feature | Raw Red Bell Pepper | Raw Green Bell Pepper | 
|---|---|---|
| Maturity | Fully ripened | Less mature | 
| Sweetness | Sweeter | More bitter | 
| Calories (per 100g) | ~26-31 calories | ~20 calories | 
| Vitamin C Content | Significantly higher (~128mg per 100g) | Lower (~80.4mg per 100g) | 
| Vitamin A (Beta-carotene) | Much higher | Lower | 
| Antioxidants | Higher levels of capsanthin and lycopene | Contains lutein | 
| Flavor Profile | Sweet and fruity | Slightly grassy and bitter | 
As the table shows, red bell peppers, having ripened longer on the vine, generally offer a more concentrated nutritional profile. However, both are excellent, low-calorie sources of vitamins and fiber, and incorporating a variety of colors into your diet is beneficial.

Conclusion
In summary, a raw red bell pepper is an exceptionally low-calorie, nutrient-rich food. With a medium pepper containing only about 37 calories, it provides a wealth of health benefits, including high levels of vitamins C and A, and various antioxidants. Its low energy density and high fiber content make it a superb addition to any diet, especially for those focused on weight management.
