Red Bell Pepper Source Review: Whole Pepper Calories, Vitamin C, and Raw vs Cooked Portions
Reviewed May 21, 2026. This page scales red bell pepper from the 100g reference into chopped cups and whole-pepper portions that match how people cook and snack.
- Calorique lists red bell pepper at 31 calories, 6g carbs, 2.1g fiber, and strong vitamin C context per 100g.
- A medium whole pepper is commonly larger than 100g, so whole-pepper searches need a separate portion row.
