What Are Net Carbs?
Net carbs are the carbohydrates absorbed by the body that affect blood sugar levels. The calculation for whole foods like bell peppers is simple: subtract the dietary fiber from the total carbohydrates. While many food labels now list this number, the term “net carbs” is not officially regulated by the Food and Drug Administration (FDA). Understanding this calculation is crucial for anyone following a ketogenic or low-carb diet, where daily carb intake is carefully managed.
Dietary fiber is a type of carbohydrate that the body cannot fully digest or absorb. It passes through the digestive system relatively intact, contributing to satiety and digestive health without impacting blood glucose in the same way as other carbs like sugar and starch. Because of this, fiber is subtracted from the total carb count to determine the 'net' or 'impact' carbs that can affect ketosis.
How Many Net Carbs are in Raw Bell Peppers?
Raw bell peppers are known for their low carbohydrate content, but the amount of total and net carbs differs by color. Green bell peppers are simply unripe versions of the red, yellow, and orange varieties, which explains the difference in their nutritional profiles and taste. The ripening process increases the sugar content, resulting in a sweeter taste and a slightly higher net carb count in the more colorful versions.
- Green Bell Peppers: These are the most keto-friendly, with the lowest net carb count. A 100-gram serving of raw green bell pepper contains approximately 4.6 grams of total carbs and 1.7 grams of dietary fiber, resulting in about 2.9 grams of net carbs.
- Red Bell Peppers: Red bell peppers are sweeter and more mature. A 100-gram serving provides about 6 grams of total carbs and 2.1 grams of fiber, which calculates to roughly 3.9 grams of net carbs.
- Yellow/Orange Bell Peppers: These varieties are similar to red peppers in their carb content. A 100-gram serving contains around 6.3 grams of total carbs and 0.9 grams of fiber, for a net carb count of about 5.4 grams.
It's important to remember that these are average values for a 100-gram portion, which is approximately half a large bell pepper.

Health Benefits of Bell Peppers Beyond Carbs
Beyond their low net carb count, bell peppers are a nutritional powerhouse packed with vitamins and antioxidants. They offer more than just a crunchy, low-calorie addition to meals.
- High in Vitamin C: Red bell peppers, in particular, are exceptionally high in Vitamin C, containing more than an orange. Vitamin C supports the immune system, promotes healthy skin, and helps with iron absorption.
- Rich in Vitamin A: Red and orange bell peppers are excellent sources of Vitamin A (beta-carotene), which is vital for vision, immune function, and reproductive health.
- Powerful Antioxidants: Bell peppers contain a variety of antioxidants, including carotenoids like capsanthin, lutein, and zeaxanthin, and polyphenols like quercetin and luteolin. These compounds fight oxidative stress, protect cells from damage, and reduce the risk of chronic diseases.
- Good for Eye Health: The carotenoids lutein and zeaxanthin are especially important for eye health, protecting the retina from damage and potentially reducing the risk of cataracts and macular degeneration.
- Source of Potassium and Fiber: Bell peppers contain potassium, which helps regulate blood pressure, and fiber, which aids digestion and promotes a feeling of fullness.
How to Incorporate Raw Bell Peppers into a Low-Carb Diet
Their versatility makes bell peppers a fantastic ingredient for a variety of low-carb recipes and snacks. Here are some simple ideas to boost your daily nutrient intake without significantly impacting your carb count:
- Raw Dippers: Slice raw bell peppers and use them as a crunchy, flavorful alternative to crackers or chips. Pair them with dips like guacamole, salsa, or hummus.
- Salad Topper: Dice up bell peppers of any color and sprinkle them over your salads for extra crunch, color, and nutrients.
