Purple cabbage, also referred to as red cabbage, belongs to the Brassica genus of plants. This group includes nutrient-dense vegetables, such as broccoli, Brussels sprouts, and kale.
It tastes similar to green cabbage. However, the purple variety is richer in beneficial plant compounds that have been linked to health benefits, such as stronger bones and a healthier heart.
Purple cabbage is also thought to lower inflammation and protect against certain types of cancers. Moreover, it’s an incredibly versatile vegetable that can be enjoyed raw, cooked, or fermented and added to a variety of dishes.
Here are 8 impressive health benefits of purple cabbage, all backed by science.
Despite being low in calories, purple cabbage contains an impressive amount of nutrients.
One cup (89 grams) of chopped, raw, purple cabbage contains the following nutrients (
- Calories: 28
- Protein: 1 gram
- Carbs: 7 grams
- Fiber: 2 grams
- Vitamin C: 56% of the Daily Value
- Vitamin K: 28% of the DV
- Vitamin B6: 11% of the DV
- Vitamin A: 6% of the DV
- Potassium: 5% of the DV
- Thiamine: 5% of the DV
- Riboflavin: 5% of the DV
Purple cabbage also provides small amounts of iron, calcium, magnesium, phosphorus, copper, and zinc.
Summary Purple cabbage is low in calories yet a good source of fiber and
vitamins A, C, K, and B6. It also contains small amounts of other vitamins and
Purple cabbage is a great source of antioxidants and other beneficial plant compounds that help protect against cellular damage.
What’s more, purple cabbage is one of the foods that offers the highest levels of antioxidants per unit cost (
It’s also a good source of sulforaphane, a sulfur-rich compound that forms when raw cabbage is cut or crushed. Sulforaphane is linked to powerful heart health benefits and cancer-fighting properties (
Summary Purple cabbage is a great source of beneficial plant compounds and
offers one of the highest amounts of health-promoting antioxidants per unit
Purple cabbage may help fight inflammation, which is thought to contribute to many diseases.
One test-tube study using an artificial model of the human gut found that certain varieties of purple cabbage reduced markers of gut inflammation by 22–40% (
Animal studies report that sulforaphane, the beneficial sulfur compound found in many cruciferous vegetables, may be to thank for its anti-inflammatory effects (
Interestingly, applying cabbage leaves to the skin also appears to reduce inflammation.
For instance, adults with arthritis who wrapped their knees in cabbage leaves once per day reported feeling significantly less pain by the end of the 4-week study. However, the cabbage wraps reduced pain less effectively than a topical pain gel (
Moreover, cabbage leaves appear to reduce breast pain, swelling, and inflammation due to increased milk supply and blood flow during the early postpartum period (
Summary Purple cabbage may help fight inflammation and reduce accompanying
symptoms, such as pain, swelling, and discomfort.
Purple cabbage may also benefit your heart.
This may be due to its content of anthocyanins, which are flavonoid antioxidants that give purple cabbage its characteristic color (
One large study found that women who regularly eat large amounts of anthocyanin-rich foods may benefit from an 11–32% lower risk of heart attacks, compared with those who eat fewer of these foods (
Purple cabbage contains more than 36 types of anthocyanins, making it an excellent source of this heart-healthy compound (
Summary Purple cabbage is a rich source of anthocyanins, which are beneficial
plant compounds that may reduce your risk of heart disease.
Purple cabbage is also rich in vitamin K1, offering a little over a quarter of the DV per cup (89 grams) (
Vitamin K1 is mostly found in plant foods, such as leafy greens and cruciferous vegetables. This distinguishes it from vitamin K2, which is found in animal products and fermented foods.
There’s evidence that both forms of vitamin K play a role in maintaining strong and healthy bones, although more research is needed to pinpoint the specific effects of each (
Summary Purple cabbage is rich in vitamins C and K1, both of which are
essential for building and maintaining strong, healthy bones. Purple cabbage
also contains smaller amounts of bone-benefitting nutrients, such as calcium,
manganese, and zinc.
Purple cabbage may help protect against certain types of cancers, though more research in humans is needed.
Experts believe this may be because it contains sulforaphane and anthocyanins — two compounds researched for their cancer-fighting properties.
Research links high intakes of cruciferous vegetables, including cabbage, to an 18% lower risk of colon cancer. Diets rich in cruciferous vegetables have also been linked to a lower risk of breast cancer (
Moreover, there’s evidence to suggest that the sulforaphane found in purple cabbage and other cruciferous vegetables may help kill cancer cells or prevent them from growing and spreading (
However, more human research is needed before strong conclusions can be made.
Summary Purple cabbage contains beneficial compounds, such as sulforaphane and
anthocyanins, which may help protect your body against certain types of
cancers. However, more research is needed to investigate these effects.
Purple cabbage may improve the function of your gut.
There’s evidence that cabbage may lower inflammation in the gut and reduce intestinal mucositis — a condition in which lesions develop in the gut, often as a side effect of cancer treatment (
Cabbage is also a good source of fiber, which keeps your gut healthy and helps it digest foods more easily.
The remaining 30% is soluble fiber, which provides food for the beneficial bacteria living in your gut. In turn, these friendly bacteria produce short-chain fatty acids (SCFAs), such as acetate, butyrate, and propionate, which feed the cells of your gut (
There’s also some evidence that drinking around 1 quart (946 ml) of cabbage juice per day may help heal gut ulcers in 7–10 days. However, the studies showing this are outdated, so more recent studies are needed to investigate this effect (
Summary Purple cabbage may help boost your gut health by reducing
inflammation, preventing gut lesions, and treating ulcers. However, more
research is needed to investigate these effects.
Purple cabbage is an incredibly versatile vegetable. You can eat it raw or cooked, and it’s well suited to accompany a variety of dishes.
For instance, it can be steamed and used to make dumpling fillings, or braised with red wine, vinegar, apples, carrots, and beets for a flavorful side dish.
Purple cabbage can also be roasted or sautéed with meats or beans, or it can be shredded and used as a nutrient-rich garnish for soups, salads, and warm dishes.
It also offers an antioxidant-rich and visually appealing alternative to green cabbage in coleslaw or sauerkraut, or it can be fermented to make kimchi.
Summary Purple cabbage is a simple and tasty addition to many dishes. It can
be eaten raw, cooked, or fermented, which adds to its versatility.
Purple cabbage is a nutrient-rich vegetable linked to a variety of health benefits.
These include reduced inflammation, a healthier heart, stronger bones, improved gut function, and perhaps even a lower risk of certain cancers.
This vegetable is also incredibly versatile and one of the most cost-efficient ways to add beneficial antioxidants to your diet.
