The Carb Count of Peppers
Bell peppers are a colorful and nutrient-rich addition to any meal, and their carb content is relatively low, making them a staple in low-carb diets. The ripeness of a bell pepper, indicated by its color, has a slight impact on its carbohydrate level, primarily due to natural sugars.
- Green Bell Peppers: These are the least ripe and have the lowest carb content. Per 100g, they contain about 4.6g of carbohydrates and 1.7g of fiber, leaving approximately 2.9g of net carbs.
- Red Bell Peppers: As the pepper ripens, the sugar content increases. Per 100g, a raw red bell pepper contains around 6g of carbs and 2.1g of fiber, for about 3.9g of net carbs.
- Yellow Bell Peppers: These are similarly higher in carbs than green peppers, with approximately 6.3g of carbs per 100g.
Fresh, raw bell peppers are predominantly water (about 92%), with carbohydrates making up most of the remaining content.
The Carb Count of Onions
Onions, a versatile aromatic vegetable, are also considered low-carb, though they contain more carbohydrates than bell peppers. Like peppers, their carb content can vary slightly by type.
- Raw Onions: A 100g serving of raw onions contains about 9.3 grams of carbs and 1.7 grams of fiber, with a net carb count of 7.6 grams.
- Sweet Onions: Generally have slightly lower carbs, with about 6.65g of net carbs per 100g.
- Red Onions: Slightly higher in carbs, around 7.7g net carbs per 100g.
- Green Onions (Scallions): Contain fewer carbs than bulb onions, with only 3.9g of net carbs per 100g.
The carbohydrates in onions are mainly from simple sugars like glucose and fructose, as well as fructans, a type of fiber. This is why they taste sweeter when cooked.
Cooking Effects on Carb Content
When peppers and onions are sautéed, the total amount of carbohydrates does not increase. The primary effect is the reduction of water content, which concentrates the nutrients and, consequently, the carbs. This means a cup of sautéed vegetables will have a higher carb density than a cup of raw vegetables simply because it contains more of the vegetable itself. However, the overall carbohydrate impact remains low, and it is a perfectly acceptable preparation method for low-carb diets, provided portion sizes are managed.

Incorporating Peppers and Onions into a Low-Carb Diet
Because they are not high in carbs, these vegetables can be enjoyed in various dishes while following a low-carb eating plan, such as the ketogenic diet. The key is moderation, especially for onions, due to their slightly higher net carb content.
Here are some simple and delicious ways to enjoy them while keeping your carb count low:
- Fajita Filling: Sautéed with chicken or beef, they create a flavorful and low-carb meal. Use lettuce wraps instead of high-carb tortillas.
- Stuffed Peppers: Fill hollowed-out peppers with a low-carb stuffing like ground meat, cauliflower rice, and cheese.
- Omelets and Scrambles: Dice them and mix into eggs for a quick, healthy, and low-carb breakfast.
- Salad Ingredients: Raw, diced peppers and onions add a fresh, crisp texture to salads.
- Kebabs: Skewer with other vegetables and protein for a simple grilled dish.
