Kohlrabi, often called a German turnip, is a cruciferous vegetable with a mild, sweet, and slightly peppery flavor. It can be enjoyed raw for a crunchy texture or cooked to bring out its mellow sweetness. For those monitoring their carbohydrate intake, understanding the nutritional profile of cooked kohlrabi is key.
The Carbohydrate Breakdown of Cooked Kohlrabi
When kohlrabi is cooked, its carbohydrate content remains low. The exact amount can vary slightly depending on the cooking method and serving size. A standard 100-gram (3.5-ounce) portion of cooked kohlrabi contains approximately 6.7 grams of total carbohydrates. In a larger, one-cup serving (around 170 grams), the total carbohydrate content is closer to 11 grams.
Net Carbs in Cooked Kohlrabi
For those on a ketogenic or other low-carb diet, net carbs are the crucial metric. Net carbs are calculated by subtracting the dietary fiber from the total carbohydrates. Cooked kohlrabi has a significant amount of fiber, which makes its net carb count very low. For example, a one-cup serving with 11g of total carbs and 6.1g of dietary fiber contains just 4.52g of net carbs. This makes it an ideal vegetable for managing blood sugar levels and promoting a feeling of fullness.
Cooked vs. Raw: A Carb Comparison
There is a common misconception that cooking significantly alters the carb content of vegetables. For kohlrabi, the difference lies more in the water content and density than in a major change to the carb profile. While boiling can cause some water absorption, it doesn't add carbohydrates. Comparing cooked and raw kohlrabi per cup reveals a slight difference primarily due to volume and density changes.
- A one-cup serving (135g) of raw kohlrabi contains about 8.4g of total carbs and 3.5g of net carbs.
- A one-cup serving (170g) of cooked kohlrabi contains about 11g of total carbs and 4.5g of net carbs.
When comparing per 100 grams, the values are very similar, confirming that the cooking process itself does not add significant carbs. Any slight variations are due to water content changes.
Comparison Table: Kohlrabi vs. Other Low-Carb Veggies
To put kohlrabi's low-carb status into perspective, here is a comparison with other common vegetables, based on a 100-gram serving:
| Vegetable | Total Carbs (g) | Dietary Fiber (g) | Net Carbs (g) |
|---|---|---|---|
| Cooked Kohlrabi | 6.7 | 1.1 | 5.6 |
| Raw Broccoli | 6.6 | 2.6 | 4.0 |
| Raw Cauliflower | 5.0 | 2.0 | 3.0 |
| Raw Cabbage | 5.8 | 2.5 | 3.3 |
| Raw Potato | 17.5 | 2.2 | 15.3 |
How to Prepare Cooked Kohlrabi for Low-Carb Meals
Kohlrabi's versatility makes it easy to incorporate into a variety of low-carb recipes. Here are a few preparation ideas:
- Steamed and Seasoned: Peel and dice the kohlrabi, then steam until tender. Season with butter, salt, pepper, and fresh dill. This simple method preserves its delicate flavor.
- Roasted 'Fries': Cut kohlrabi into fry-sized strips, toss with olive oil, salt, pepper, and paprika, then bake at 400°F (200°C) until golden and crispy.
- Creamy Purée: Boil kohlrabi until very soft. Drain and mash with a small amount of heavy cream, garlic powder, and a sprinkle of nutmeg for a low-carb alternative to mashed potatoes.
- Sautéed: Dice kohlrabi and sauté in a pan with garlic and your favorite herbs. This brings out a nice sweetness and a tender-crisp texture.
Health Benefits Beyond the Carb Count
In addition to being a low-carb powerhouse, kohlrabi is packed with other essential nutrients:
- High in Vitamin C: Just one cup of kohlrabi can provide more than your daily recommended intake of Vitamin C, a powerful antioxidant.
- Rich in Fiber: Both soluble and insoluble fiber are present, aiding in digestion, promoting gut health, and stabilizing blood sugar.
- Heart Health: Kohlrabi contains glucosinolates and isothiocyanates, compounds that help reduce inflammation and lower the risk of heart disease.
- Immune Support: The high Vitamin C and Vitamin B6 content contribute to a strong immune system.
Conclusion
For anyone on a low-carb or keto diet, cooked kohlrabi is a fantastic choice. With just 6.7g of total carbs per 100g and even lower net carbs, it provides a delicious and nutrient-dense alternative to high-starch vegetables. Its mild flavor and versatile nature allow it to be prepared in numerous ways, from simple steamed sides to satisfying roasted fries. The minimal effect of cooking on its carbohydrate profile means you can enjoy it without concern, benefiting from its high fiber, vitamin, and antioxidant content.
