Cabbage does contain carbohydrates, but in small amounts. A cup of raw green cabbage has roughly 5 grams of carbs, and about 2 grams of that is fiber. That leaves around 3 grams of net carbs per cup. For anyone watching carb intake, cabbage sits firmly in the low-carb category.
Does Cabbage Contain Carbs?
Yes. Cabbage is not a zero-carb food. But the amount is low compared to most other vegetables and almost all grains and starches.
The carbohydrate in cabbage comes in three main forms. There is fiber, which your body does not digest. There are natural sugars, mostly glucose and fructose. And there are small amounts of starch. The fiber makes up a large share of the total carb count, which is why cabbage is often described as low in “net carbs” — total carbs minus fiber.
Here is how the common types of cabbage compare per one cup, raw and shredded, based on USDA nutritional data:
| Cabbage Type | Total Carbs | Fiber | Net Carbs | Calories |
|---|---|---|---|---|
| Green (raw, shredded) | ~5 g | ~2 g | ~3 g | ~22 |
| Red (raw, shredded) | ~5 g | ~2 g | ~3 g | ~28 |
| Savoy (raw, shredded) | ~6 g | ~2 g | ~4 g | ~19 |
| Napa (raw, shredded) | ~2 g | ~0.5 g | ~1.5 g | ~13 |
These numbers shift with cooking. A cup of cooked cabbage weighs more than a cup of raw shredded cabbage because cooking breaks down cell walls and the leaves pack together. So a cup of cooked cabbage can carry more carbs than a cup of raw — not because cooking adds carbs, but because you are fitting more cabbage into the same cup.
How Many Carbs Are in a Cup of Cabbage?
One cup of raw, shredded green cabbage has about 5 grams of total carbohydrate. Red cabbage is nearly identical. Napa cabbage is lower, closer to 2 grams. Savoy runs slightly higher.
To put that in context, one medium apple has around 25 grams of carbs. A slice of white bread runs about 14 grams. A half-cup of cooked white rice is roughly 22 grams. Cabbage delivers a fraction of that while filling the same space on a plate.
This is why cabbage shows up so often in low-carb and keto-style eating. It adds volume and crunch without a meaningful carb load. A large bowl of coleslaw made with a low-sugar dressing might land under 5 grams of net carbs. The same bowl made with a sweet, creamy dressing could triple that, because the dressing — not the cabbage — carries the carbs.
That last point matters. When people track carbs in a cabbage dish, the cabbage is rarely the problem. Sugar, honey, fruit, breadcrumbs, or starchy fillers usually account for most of the total.
Is Cabbage a Low-Carb Vegetable?
Cabbage is one of the lowest-carb vegetables you can eat. It belongs in the same group as leafy greens, broccoli, cauliflower, and zucchini.
What makes cabbage useful is not just its low carb count but its bulk. It is mostly water — over 90 percent by weight. That means you can eat a large portion, feel full, and take in very few carbs and calories. Few foods do this as cheaply or as easily.
The fiber in cabbage also slows digestion. Fiber is a carbohydrate, but it passes through your system largely undigested. It feeds gut bacteria and adds to stool bulk. Because fiber is not broken down into glucose the way starch and sugar are, it generally has little effect on blood sugar. This is why net carbs — total carbs minus fiber — is the number many people with diabetes or on low-carb diets actually track.
One clarification worth making: “net carbs” is a convenient label, not a formal regulatory or clinical term. Different countries and food authorities count carbohydrates differently on labels. Fiber is still a carbohydrate in the strict chemical sense. The net carb idea is a practical shortcut, and it works reasonably well for most people, but it is not a standardized measurement.
Does Cabbage Affect Blood Sugar?
Cabbage has a low effect on blood sugar. It has a low glycemic index, which is a measure of how quickly a food raises blood glucose compared to pure glucose.
Several things about cabbage work in its favor here. Its carbohydrate content is low to begin with. Much of that carbohydrate is fiber, which is not digested into glucose. And the physical structure of the vegetable — dense, fibrous cell walls — slows how fast the remaining sugars reach your bloodstream.
For people managing type 2 diabetes or prediabetes, non-starchy vegetables like cabbage are generally encouraged as part of meals. They add volume and nutrients without a sharp glucose spike. That said, cabbage is not a treatment for diabetes, and no single food controls blood sugar on its own. Total diet, medication, and activity all matter far more than any one vegetable.
If you take blood sugar medication, large changes to your diet can shift your numbers. Talk with your clinician before making significant changes.
What Else Is in Cabbage Besides Carbs?
Cabbage is low in calories and carries a range of nutrients. It is a source of vitamin C, vitamin K, and folate. Red cabbage also provides anthocyanins, the pigments that give it color and that act as antioxidants.
The nutrient profile varies by type and by how it is prepared. Boiling cabbage leaches some water-soluble vitamins, like vitamin C, into the cooking water. Steaming, stir-frying, or eating it raw preserves more. This is a general pattern for water-soluble vitamins, not something unique to cabbage.
Vitamin K deserves a mention. Cabbage is a decent source, and vitamin K can interact with blood-thinning medications like warfarin. People on these medications are often advised to keep their vitamin K intake steady rather than avoid it. If that applies to you, your clinician can guide you on consistency. This is well-established clinical practice.
What cabbage does not do is cure disease or detox your body. It is a nutritious, low-carb vegetable. That is a real and useful thing. It is not a medicine.
Does Cooking Cabbage Change Its Carbs?
Cooking does not add or remove carbohydrates in any meaningful way. It changes water content, which changes how much cabbage fits in a measured cup.
When cabbage cooks, it releases water and the leaves soften and collapse. A cup of cooked cabbage holds more actual cabbage than a cup of raw shredded cabbage. So the carb count per cup goes up, but the carb count per gram of cabbage stays about the same.
Fermentation is a different story. When cabbage is fermented to make sauerkraut or kimchi, bacteria consume some of the natural sugars and convert them into acids. This can lower the sugar content. The exact change depends on the fermentation process and how long it runs, so it is hard to give a single number. Commercially made sauerkraut and kimchi may also have sugar added, which can raise the carb count back up. Checking the label is the reliable move.
One more practical note: cooking method affects the whole dish, not just the cabbage. Frying cabbage in a lot of oil, or simmering it with sugar, changes the nutrition far more than the cooking itself does.
How Does Cabbage Fit Into a Low-Carb Diet?
Cabbage fits easily into low-carb eating because it is versatile and cheap. It works raw in slaws, sautéed as a side, stuffed as a wrapper, or roasted as a main vegetable.
- Use it as a base for slaws with oil-and-vinegar dressings instead of sweet creamy ones.
- Sauté it with garlic and olive oil as a low-carb side.
- Use large leaves as a wrap instead of bread or tortillas.
- Add it to soups and stir-fries to bulk up a meal without adding carbs.
- Check labels on sauerkraut and kimchi for added sugar.
The main caution is portion and preparation, not the cabbage itself. A plain serving adds very few carbs. A sweetened or starchy recipe can add many. If you are counting carbs, the recipe around the cabbage usually matters more than the cabbage.
Frequently Asked Questions
How many carbs are in a cup of cabbage?
One cup of raw shredded green or red cabbage has about 5 grams of total carbs, with roughly 2 grams of that being fiber. That leaves around 3 grams of net carbs.
Is cabbage keto-friendly?
Yes, cabbage fits well into a keto-style diet because it is low in net carbs. A cup of raw cabbage has only about 3 grams of net carbs, though dressings and added ingredients can raise that quickly.
Does cabbage raise blood sugar?
Cabbage has a low glycemic index and a small effect on blood sugar. Most of its carbohydrate is fiber, which is not digested into glucose.
Is cooked cabbage higher in carbs than raw?
A cup of cooked cabbage can have more carbs than a cup of raw because cooked leaves pack more tightly into the cup. Per gram of cabbage, the carb content stays about the same.
