You probably think of cabbage as that soggy stuff at the bottom of a coleslaw bowl or the pungent smell wafting from a pot of corned beef. Honestly, it has a bit of a PR problem. Most people see it as filler. But if you actually look at the nutrition info on cabbage, it’s kind of wild how much this humble, dirt-cheap ball of leaves packs under the hood. It isn't just "roughage." It is a complex chemical factory that has been fueling humans for thousands of years.
Cabbage is a cruciferous vegetable. That puts it in the same elite family as kale, broccoli, and Brussels sprouts. However, because it’s so inexpensive, we tend to respect it less than the trendy greens. That’s a mistake.
What’s actually inside? The raw data.
Let's get the numbers out of the way because they’re impressive for something that is 92% water. One cup of raw, chopped green cabbage (about 89 grams) contains roughly 22 calories. That is basically nothing. You get about 1 gram of protein and 2 grams of fiber. But the real magic is in the micronutrients. That same single cup gives you about 85% of the Daily Value (DV) for Vitamin K1 and over 50% of the DV for Vitamin C.

Think about that.
You could eat a massive bowl of this stuff, feel completely full, and you've barely touched your calorie budget for the day while absolutely crushing your vitamin requirements. It’s a volume-eater’s dream. Vitamin K1 is crucial for blood clotting and bone metabolism. If you’re on blood thinners like Warfarin (Coumadin), you actually have to be careful with cabbage because its high Vitamin K content can interfere with the medication. Always talk to your doctor about that.
Vitamin C is the other big player here. We usually think of oranges when we think of Vitamin C, but red cabbage actually puts many citrus fruits to shame. A cup of red cabbage has significantly more Vitamin C than the green variety. It’s an antioxidant powerhouse that helps with collagen production and keeps your immune system from totally tanking during flu season.
The Anthocyanin Factor in Red Cabbage
If you have the choice, grab the purple stuff. Red cabbage contains anthocyanins. These are the same pigments that give blueberries and raspberries their "superfood" status. Research, including studies published in the Journal of Agricultural and Food Chemistry, suggests these compounds help reduce inflammation and might lower the risk of cardiovascular disease.
Inflammation is the root of so many modern health issues. Eating foods that actively fight it—rather than fueling it—is a game-changer. Red cabbage has about 36 different kinds of potent anthocyanins. It’s basically medicine you can buy for two dollars at the grocery store.
The "Sulphur" Smell and Cancer Research
Ever notice that distinct, slightly funky smell when cabbage cooks? That is caused by glucosinolates. These are sulfur-containing compounds. When you chop, chew, or digest cabbage, these compounds break down into biologically active substances like isothiocyanates and indoles.
This is where the nutrition info on cabbage gets scientifically heavy.
Institutions like the National Cancer Institute have looked into these compounds. In lab settings, indoles and isothiocyanates have been shown to inhibit the development of cancer in several organs, including the bladder, breast, colon, and liver. They help protect cells from DNA damage and can even induce cell death (apoptosis) in carcinogens.
Now, does this mean cabbage cures cancer? No.
Nutrition is never that simple. But including cruciferous vegetables regularly is a huge part of a preventative lifestyle. It’s about stacking the deck in your favor.

Gut Health and the Fermentation Miracle
Cabbage is arguably the best vehicle for probiotics on the planet. When you ferment cabbage to make sauerkraut or kimchi, you aren't just preserving it. You’re transforming it.
The natural sugars in the cabbage are broken down by Lactobacillus bacteria. This creates lactic acid, which preserves the veg and gives it that tang. But more importantly, it creates a massive dose of live probiotics. These "good" bacteria are essential for a healthy microbiome.
Most people’s guts are a mess because of processed sugar and stress. Sauerkraut helps fix that.
- It improves digestion.
- It boosts the immune system (most of which lives in your gut).
- It might even improve mental clarity through the gut-brain axis.
Just make sure you’re buying the "raw" or "unpasteurized" versions from the refrigerated section. If it’s shelf-stable in a can, the heat from canning killed all the beneficial bacteria. You’re just eating salty leaves at that point. Still fiber, but no probiotic punch.
Why Cabbage Beats Kale (Sometimes)
Kale had a huge moment. It was everywhere. But cabbage is arguably more versatile and easier on the digestive tract for some people when cooked. Raw kale can be tough and bitter. Cabbage, especially varieties like Napa or Savoy, has a much more delicate texture and a sweeter profile when sautéed.
Also, let’s talk about price. In 2026, food prices are no joke. Cabbage remains one of the most nutrient-dense foods per dollar spent. You can buy a massive head of green cabbage for less than the price of a fancy latte and feed a family for two nights.
Common Misconceptions: The "Gas" Issue
"I can't eat cabbage, it makes me too bloated."
I hear this all the time. Here’s the deal: Cabbage contains raffinose, a complex sugar that humans can’t digest very well. It passes through to the large intestine where bacteria break it down, producing gas as a byproduct.
If you aren't used to fiber, jumping into a big raw cabbage salad will hurt. Your gut isn't ready.
The fix is easy. Start small. Cook it thoroughly first, which helps break down some of those tough fibers and sugars. Or, stick to the fermented versions where the bacteria have already done the heavy lifting of digestion for you. Your stomach will thank you.

Vitamin U: The Secret Weapon for Ulcers
You won't find "Vitamin U" on most standard nutrition labels. It isn't actually a vitamin; it’s a term coined in the 1950s for S-methylmethionine.
Decades ago, Dr. Garnett Cheney at Stanford University conducted a famous (though small) study where he gave cabbage juice to patients with peptic ulcers. The results were shocking. The patients drinking cabbage juice healed much faster than those on standard treatments.
While modern medicine uses proton pump inhibitors and antibiotics (since we now know H. pylori causes most ulcers), cabbage juice remains a potent home remedy for soothing the stomach lining. It’s high in glutamine, an amino acid that is basically "fuel" for the cells lining your digestive tract.
Quick Nutrition Comparison: Green vs. Red vs. Savoy
- Green Cabbage: The standard. Highest in Vitamin K. Best for fermenting.
- Red/Purple Cabbage: The antioxidant king. More Vitamin C and Vitamin A than green.
- Savoy Cabbage: Crinkly leaves. More Vitamin A than green, but less Vitamin C. It’s the easiest to digest raw.
- Napa (Chinese) Cabbage: High in folate and slightly lower in fiber, making it very gentle on the stomach.
Practical Ways to Use This Info
Knowing the nutrition info on cabbage is one thing, but you actually have to eat it. Don't just boil it into mush. That destroys the heat-sensitive Vitamin C and makes it smell like old socks.
Instead, try roasting it. Slice a head of cabbage into "steaks," brush them with olive oil, salt, and garlic powder, and roast at 400°F until the edges are crispy and charred. It turns sweet and nutty.
Or, use it as a taco topper. Instead of flavorless iceberg lettuce, use thinly sliced red cabbage tossed with lime juice. You get a massive crunch and a huge hit of anthocyanins with every bite.
Actionable Next Steps
- Swap your lettuce: Next time you make a salad, use a 50/50 mix of spinach and shredded cabbage. It adds crunch and significantly ups your Vitamin K and C intake without changing the flavor much.
- Add a fermented side: Get one jar of raw sauerkraut. Eat just two tablespoons a day with dinner. Don't cook it; eat it cold to keep the probiotics alive.
- Go for color: If you usually buy green cabbage, switch to red this week. The extra antioxidants are worth the extra few cents.
- Juice it for digestion: If you struggle with heartburn or mild gastritis, try 4 ounces of fresh cabbage juice on an empty stomach for a week. It’s an old-school remedy for a reason.
Cabbage isn't a "diet" food to be endured. It’s a functional powerhouse. It's cheap, it lasts forever in the fridge, and it’s one of the few things you can eat in massive quantities that actually makes you healthier the more you consume. Stop ignoring it in the produce aisle.
