Caloric Breakdown of a Green Bell Pepper
The average medium green bell pepper, weighing approximately 119 grams, is an exceptionally low-calorie food. Its caloric content is primarily derived from its small amount of carbohydrates and protein, as it is composed of over 92% water. This high water and fiber content contributes to a feeling of fullness without adding significant calories, making it a great food for those managing their weight. The raw, green variety has fewer calories and less sugar than its red, yellow, or orange counterparts, which have matured longer on the vine.
Raw vs. Cooked: How Preparation Affects Calories
While the raw green bell pepper is naturally low in calories, the final count can change depending on how it's prepared. The difference, however, comes from added ingredients, not the pepper itself. For example:
- Raw: The purest form with the lowest caloric impact. Adding slices to a salad won't change its calorie count, but dressing will.
- Roasted or Grilled: Cooking without oil or other fats retains the pepper's natural calorie level. The heat simply softens the vegetable and brings out its sweeter flavor.
- Sautéed: Sautéing often involves using oil or butter, which increases the total calories of the dish. A healthy approach is to use minimal cooking spray or olive oil.
- Stuffed: Stuffed peppers can vary widely in calorie count. A filling of lean ground turkey and vegetables will keep it relatively low, while a filling of high-fat cheese and sausage will increase it dramatically.
A Complete Nutritional Profile
Beyond just calories, the green bell pepper is a nutritional powerhouse. It's an excellent source of essential vitamins and minerals that support overall health.
- Vitamin C: A single medium green bell pepper provides more than the daily recommended intake of Vitamin C, a powerful antioxidant that supports the immune system and aids in iron absorption.
- Vitamin B6: This vitamin plays a crucial role in metabolism and the creation of red blood cells.
- Vitamin K: Important for blood clotting and bone health.
- Potassium: An essential mineral that helps regulate blood pressure.
- Folate (Vitamin B9): Supports cell growth and function, especially important during pregnancy.
- Antioxidants: Contains lutein and zeaxanthin, which are particularly beneficial for eye health.
Calorie Comparison: Green Bell Pepper vs. Other Vegetables
To put the green bell pepper's low-calorie status into perspective, let's compare it to a few other common vegetables based on a standard 100-gram serving.
| Vegetable | Calories (per 100g) | Primary Macro | Water Content |
|---|---|---|---|
| Green Bell Pepper | 20 kcal | Carbohydrates | 94% |
| Cucumber | 15 kcal | Carbohydrates | 95% |
| Asparagus | 20 kcal | Carbohydrates | 93% |
| Carrots | 41 kcal | Carbohydrates | 88% |
| Broccoli | 34 kcal | Carbohydrates/Protein | 89% |
| Spinach | 23 kcal | Protein/Carbohydrates | 91% |
This comparison table clearly demonstrates that the green bell pepper is among the lowest-calorie vegetable options, similar to cucumber and asparagus.

The Myth of Negative Calorie Foods
There is a common myth that some foods, like celery or bell peppers, have "negative calories" because the energy required to digest them is more than the energy they contain. While green bell peppers are low in calories and the body does use energy for digestion, this expenditure is significantly less than the calories provided by the food. So, while they are excellent for weight management, they are not a negative calorie food in the technical sense.
Conclusion
In summary, a medium green bell pepper provides approximately 24 calories, solidifying its place as a fantastic choice for anyone looking to eat healthy and manage their weight. Its nutritional value extends far beyond its low-calorie count, offering a rich source of vitamins, antioxidants, and fiber. Whether enjoyed raw in a salad or cooked in a healthy stir-fry, the green bell pepper is a versatile and beneficial addition to any balanced diet.
