The Ripening Process and Bell Pepper Colors
All bell peppers start out green and develop different colors like yellow, orange, and red as they ripen on the plant. Green peppers are simply unripe, while red peppers are fully mature. This ripening process is key to the differences in their nutritional content and flavor.
Why Green Peppers are Lowest in Calories
Green bell peppers are harvested before they fully ripen, giving them a slightly bitter taste and firmer texture compared to other colors. Since they are less mature, they have not converted as much of their starches into natural sugars, resulting in lower carbohydrate and sugar content. As carbohydrates contribute to calories, green peppers naturally have the fewest calories per serving. This makes them an excellent choice for those managing calorie intake.
How Ripeness Affects Nutrients and Flavor
While green peppers are lowest in calories, other colors offer varying nutritional benefits as they ripen.

Choosing the Right Pepper for Your Diet
If your primary focus is the lowest calorie count, green peppers are the best choice. However, for maximizing vitamins C and A, red bell peppers are superior. Incorporating a mix of colors provides a wider array of nutrients and antioxidants. A healthy diet emphasizes nutrient variety.
Conclusion
To answer which color pepper is lowest in calories, it's green. This is because it is less ripe and contains less sugar and fewer carbohydrates than other colors. While red, yellow, and orange peppers are higher in certain vitamins and antioxidants, all bell peppers are a healthy, low-calorie addition to meals. The best choice depends on flavor preference and specific nutritional goals, but from a purely caloric perspective, green is the lowest.
