Health Benefits of Bell Peppers
Bell peppers are one of the best dietary sources of vitamin C, with 128mg per 100g. This exceeds the 90mg daily recommendation for adults and supports immune function, collagen synthesis, and antioxidant protection. Vitamin C also enhances the absorption of non-heme iron from plant foods, making bell peppers a useful pairing with iron-rich vegetables or legumes.
The vitamin A content (157mcg per 100g) supports eye health, immune response, and skin maintenance. The folate (46mcg per 100g) is important for DNA repair and cell division, useful during recovery from intense training.
For anyone cutting calories or trying to increase meal volume without adding significant macros, bell peppers are ideal. At 26 calories per 100g, you can eat a large amount and barely impact your calorie budget. They are also rich in antioxidants, particularly capsanthin in red peppers, which reduce oxidative stress caused by exercise.
Bell peppers are easy to add to meal prep. Slice them raw for snacking, roast them as a side, or dice them into eggs, rice, or protein bowls for added micronutrient density with minimal calorie cost.
Dietary Considerations
Bell peppers are vegan, vegetarian, and naturally gluten-free. With only 6g of carbs per 100g, they are low enough in carbohydrates to fit into most low-carb and keto diets. They contain no fat and no cholesterol. Bell peppers are paleo and whole-food plant-based diet friendly. They are a good option for weight loss due to their very low calorie density and high water and fiber content. There are no common allergens or dietary concerns associated with bell peppers. Nightshade sensitivity is rare but does exist in some individuals.
