Yes, there are carbohydrates in bell peppers, but they are considered a low-carb vegetable, making them a great option for many dietary plans, including keto. The key to understanding their carb impact lies in looking at both total carbs and net carbs. Bell peppers, regardless of color, are primarily composed of water, which keeps their caloric and carbohydrate density low. The carbs they do contain are mostly simple sugars like glucose and fructose, which give ripe peppers their sweet taste, along with a decent amount of dietary fiber.
The Carb Breakdown in Bell Peppers
To accurately assess the carb content of bell peppers, it's important to look at the total carbohydrate count and the net carbohydrate count. Net carbs are calculated by subtracting the grams of dietary fiber from the total carbohydrates. Fiber is a type of carbohydrate that the body cannot digest, so it does not raise blood sugar levels in the same way as other carbs. Because bell peppers contain a good amount of fiber, their net carb count is significantly lower than their total carb count.
Carb Differences by Color
The color of a bell pepper indicates its ripeness, which also affects its carbohydrate and sugar content. Unripe green bell peppers are less sweet and have a slightly more bitter flavor compared to their fully ripe red, yellow, and orange counterparts. As a pepper ripens, its sugar content increases, resulting in a sweeter taste and a slightly higher carb count. This is why green peppers are often favored for those seeking the absolute lowest carb option, though the difference is minimal and all colors remain low-carb choices.
Bell Peppers and Low-Carb Diets
Bell peppers are a staple in many low-carb and ketogenic diet plans. Their low net carb count allows them to be enjoyed liberally without pushing you out of ketosis. Their versatility also makes them easy to incorporate into a wide range of recipes, adding flavor, texture, and a boost of nutrients. You can use them in stuffed recipes, stir-fries, salads, and as a crunchy snack.

Beyond Carbs: The Nutritional Powerhouse
Bell peppers offer a lot more than just being a low-carb food. They are exceptionally rich in beneficial vitamins, minerals, and antioxidants.
- Vitamin C: Red bell peppers, in particular, are an incredible source of vitamin C, providing more than 169% of the recommended daily intake in a single medium-sized pepper. This is crucial for immune function, collagen production, and acting as a powerful antioxidant. The Healthline article on Bell Peppers 101 provides more detail on these benefits.
- Vitamin A & Beta-Carotene: Red and orange bell peppers are high in provitamin A (beta-carotene), which the body converts into vitamin A. This vitamin is essential for eye health and skin maintenance.
- Antioxidants: Bell peppers are loaded with antioxidants like carotenoids (capsanthin, lutein, zeaxanthin), flavonoids, and quercetin. These compounds protect cells from oxidative damage and may help reduce the risk of chronic diseases.
- Other Nutrients: They also provide a good amount of Vitamin B6, Vitamin K1, folate, and potassium, all of which contribute to overall health.
Incorporating Bell Peppers into Low-Carb Meals
Bell peppers are incredibly versatile and easy to add to a low-carb diet. Here are some ideas:
- Snack Raw: Slice them into strips for dipping in guacamole, hummus, or a creamy ranch dressing.
- Stuffed Peppers: Hollow out the bell peppers and stuff them with a keto-friendly filling like seasoned ground beef, cauliflower rice, and cheese.
- Fajitas and Stir-Fries: Sautéed sliced bell peppers and onions make an excellent addition to chicken or beef fajitas, stir-fries, and other skillet meals.
- Omelets and Scrambles: Dice bell peppers and toss them into your morning eggs for added flavor, color, and nutrients.
- Roasted Side Dish: Roast bell pepper strips with olive oil, salt, and pepper until soft for a simple yet flavorful side dish.
Conclusion
In summary, bell peppers do contain carbohydrates, but they are an ideal low-carb food choice due to their high fiber and water content. The net carbs are low across all colors, with green peppers being the lowest. Their impressive nutritional profile, rich in vitamins C and A, antioxidants, and fiber, makes them a healthy addition to any diet. So, whether you are following a specific low-carb plan or simply looking for a nutritious and versatile vegetable, bell peppers are a smart choice. You can enjoy them raw or cooked in numerous ways to add flavor and health benefits to your meals.
