The Truth About Bell Pepper Calories
Despite popular belief, bell peppers, like virtually all foods, do contain calories. The "zero-calorie" or "negative calorie" label is a myth often applied to foods that are extremely low in energy and high in water and fiber. For example, a 100-gram serving of raw red bell pepper contains roughly 26 calories, while a medium-sized one averages about 37 calories. The high water content (around 92%) and fibrous nature give them a low calorie density, which can contribute to a feeling of fullness without consuming many calories. However, the energy required to digest them is less than the energy they provide, so the concept of expending more calories to eat them than you gain is simply untrue.
Why the Low-Calorie Perception Exists
The perception of bell peppers being calorie-free stems from their extremely low energy density. In the context of a meal, the calories from a handful of pepper slices are often negligible compared to other ingredients. This has led many to consider them a guilt-free snack or filler vegetable. The high volume and weight provided by a low-calorie-dense food like bell peppers can aid in weight management by increasing satiety and displacing higher-calorie foods in the diet. This principle is a key part of many healthy eating and weight loss strategies.
Bell Pepper Calorie Density by Color
An interesting aspect of bell pepper nutrition is how the calorie and nutrient content changes with ripeness. All bell peppers start green and mature into yellow, orange, and red varieties. The longer they ripen on the vine, the sweeter and more calorically dense they become due to higher sugar content. This maturation process also significantly boosts their antioxidant and vitamin levels.
Comparing Green vs. Red Bell Peppers
Green bell peppers are less ripe and have a slightly more bitter taste. They are the lowest in calories of the common varieties. As they ripen, they turn red, yellow, or orange, with red being the most mature and nutrient-rich. This difference in maturity accounts for the slight caloric variation and distinct flavor profiles.

Conclusion
In conclusion, the idea that bell peppers are zero calories is a pervasive myth. While they are not calorie-free, their caloric content is exceptionally low, making them a cornerstone of a healthy, low-energy-density diet. Their high water, fiber, and nutrient content allow you to consume a larger volume of food for fewer calories, which is beneficial for weight management and overall health. Beyond their low-calorie profile, bell peppers are a rich source of vitamins, antioxidants, and minerals that support immune function, eye health, and digestion. By incorporating these vibrant vegetables into your diet, you can enjoy a delicious and nutritious boost without worry. For more detailed nutritional information, consult the USDA's FoodData Central.
Understanding Bell Pepper Calories
Not Zero-Calorie: Bell peppers do contain a small amount of calories, mainly from natural sugars and carbohydrates. Color Matters: Calorie count increases with ripeness; green peppers are lowest, while red, yellow, and orange are slightly higher due to more sugar. High in Water: Composed of over 90% water, bell peppers are a low-energy-density food that helps with satiety. Nutrient-Dense: Despite being low in calories, they are packed with vitamins A, C, and antioxidants. Weight Management: Their low calorie density allows for larger, more filling portions that aid in weight control.
