Despite its impressive nutrient content, cabbage is often overlooked.
While it may look a lot like lettuce, it actually belongs to the Brassica genus of vegetables, which includes broccoli, cauliflower and kale (1).
It comes in a variety of shapes and colors, including red, purple, white and green, and its leaves can be either crinkled or smooth.
This vegetable has been grown around the world for thousands of years and can be found in a variety of dishes, including sauerkraut, kimchi and coleslaw.
Additionally, cabbage is loaded with vitamins and minerals.
This article uncovers 9 surprising health benefits of cabbage, all backed by science.
1. Cabbage Is Packed With Nutrients
Even though cabbage is very low in calories, it has an impressive nutrient profile.
In fact, just 1 cup (89 grams) of raw green cabbage contains (2):
- Calories: 22
- Protein: 1 gram
- Fiber: 2 grams
- Vitamin K: 85% of the RDI
- Vitamin C: 54% of the RDI
- Folate: 10% of the RDI
- Manganese: 7% of the RDI
- Vitamin B6: 6% of the RDI
- Calcium: 4% of the RDI
- Potassium: 4% of the RDI
- Magnesium: 3% of the RDI
Cabbage also contains small amounts of other micronutrients, including vitamin A, iron and riboflavin.
As you can see in the list above, it is rich in vitamin B6 and folate, both of which are essential for many important processes in the body, including energy metabolism and the normal functioning of the nervous system.
In addition, cabbage is high in fiber and contains powerful antioxidants, including polyphenols and sulfur compounds (2).
Antioxidants protect the body from damage caused by free radicals. Free radicals are molecules that have an odd number of electrons, making them unstable. When their levels become too high, they can damage your cells.
Cabbage is especially high in vitamin C, a potent antioxidant that may protect against heart disease, certain cancers and vision loss (3Trusted Source, 4Trusted Source, 5Trusted Source).
SUMMARY:Cabbage is a low-calorie vegetable that is rich in vitamins, minerals and antioxidants.
2. It May Help Keep Inflammation in Check
Inflammation isn’t always a bad thing.
In fact, your body relies on the inflammatory response to protect against infection or speed up healing. This kind of acute inflammation is a normal response to an injury or infection.
On the other hand, chronic inflammation that occurs over a long period of time is associated with many diseases, including heart disease, rheumatoid arthritis and inflammatory bowel disease (6Trusted Source).
Cruciferous vegetables like cabbage contain many different antioxidants that have been shown to reduce chronic inflammation (7).
In fact, research has shown that eating more cruciferous vegetables reduces certain blood markers of inflammation (8Trusted Source).
One study including over 1,000 Chinese women showed that those who ate the highest amounts of cruciferous vegetables had considerably lower levels of inflammation, compared to those who ate the lowest amounts (9).
Sulforaphane, kaempferol and other antioxidants found in this remarkable group of plants are likely responsible for their anti-inflammatory effect (10, 11Trusted Source).
SUMMARY:Cabbage contains powerful antioxidants that may help reduce inflammation.
3. Cabbage Is Packed With Vitamin C
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that serves many important roles in the body.
For instance, it’s needed to make collagen, the most abundant protein in the body. Collagen gives structure and flexibility to the skin and is critical for the proper functioning of the bones, muscles and blood vessels (12).
Additionally, vitamin C helps the body absorb non-heme iron, the type of iron found in plant foods.
What’s more, it’s a powerful antioxidant. In fact, it has been extensively researched for its potential cancer-fighting qualities (13).
Vitamin C works to protect the body from damage caused by free radicals, which has been associated with many chronic diseases, including cancer (14Trusted Source).
Evidence suggests that a diet high in vitamin-C-rich foods is associated with a lower risk of certain cancers (13, 15Trusted Source, 16Trusted Source).
In fact, a recent analysis of 21 studies found that the risk of lung cancer decreased by 7% for each daily 100-mg increase in vitamin C intake (17Trusted Source).
However, this study was limited because it could not determine whether the decreased risk of lung cancer was caused by vitamin C or other compounds found in fruits and vegetables.
While many observational studies have found a link between higher vitamin C intake and a reduced risk of certain cancers, results from controlled studies remain inconsistent (18Trusted Source, 19, 20Trusted Source).
Even though more research is needed to determine this vitamin’s role in cancer prevention, it’s certain that vitamin C plays a key role in many important functions in the body.
While both green and red cabbage are excellent sources of this potent antioxidant, red cabbage contains about 30% more.
One cup (89 grams) of chopped red cabbage packs in 85% of the recommended intake for vitamin C, which is the same amount found in a small orange (21).
SUMMARY:Your body needs vitamin C for many important functions, and it is a potent antioxidant. Red cabbage is particularly high in this nutrient, providing about 85% of the RDI per cup (89 grams).
4. It Helps Improve Digestion
If you want to improve your digestive health, fiber-rich cabbage is the way to go.
This crunchy vegetable is full of gut-friendly insoluble fiber, a type of carbohydrate that can’t be broken down in the intestines. Insoluble fiber helps keep the digestive system healthy by adding bulk to stools and promoting regular bowel movements (22Trusted Source).
What’s more, it’s rich in soluble fiber, which has been shown to increase the number of beneficial bacteria in the gut. This is because fiber is the main fuel source for friendly species like Bifidobacteria and Lactobacilli (23Trusted Source).
These bacteria perform important functions like protecting the immune system and producing critical nutrients like vitamins K2 and B12 (24Trusted Source, 25Trusted Source).
Eating more cabbage is an excellent way to keep your digestive system healthy and happy.
SUMMARY:Cabbage contains insoluble fiber, which keeps the digestive system healthy by providing fuel for friendly bacteria and promoting regular bowel movements
5. May Help Keep Your Heart Healthy
Red cabbage contains powerful compounds called anthocyanins. They give this delicious vegetable its vibrant purple color.
Anthocyanins are plant pigments that belong to the flavonoid family.
Many studies have found a link between eating foods rich in this pigment and a reduced risk of heart disease (26Trusted Source).
In a study including 93,600 women, researchers found that those with a higher intake of anthocyanin-rich foods had a much lower risk of a heart attack (27Trusted Source).
Another analysis of 13 observational studies that included 344,488 people had similar findings. It found that increasing flavonoid intake by 10 mg per day was associated with a 5% lower risk of heart disease (28).
Increasing your intake of dietary anthocyanins has also been shown to reduce blood pressure and the risk of coronary artery disease (29Trusted Source, 30Trusted Source).
Inflammation is known to play a major role in the development of heart disease, and anthocyanins’ protective effect against it is likely due to their anti-inflammatory qualities.
Cabbage contains more than 36 different kinds of potent anthocyanins, making it an excellent choice for heart health (31).
SUMMARY:Cabbage contains powerful pigments called anthocyanins, which have been shown to reduce the risk of heart disease.
6. May Lower Blood Pressure
High blood pressure affects more than one billion people worldwide and is a major risk factor for heart disease and stroke (32Trusted Source).
Doctors often advise patients with high blood pressure to reduce their salt intake. However, recent evidence suggests that increasing your dietary potassium is just as important for lowering blood pressure (33).
Potassium is an important mineral and electrolyte that the body needs to function properly. One of its main jobs is to help regulate blood pressure by counteracting the effects of sodium in the body (34).
Potassium helps excrete excess sodium through urine. It also relaxes blood vessel walls, which lowers blood pressure.
While both sodium and potassium are important for health, modern diets tend to be too high in sodium and too low in potassium (35Trusted Source).
Red cabbage is an excellent source of potassium, delivering 12% of the RDI in a 2-cup (178-gram) serving (21).
Eating more potassium-rich cabbage is a delicious way to lower high blood pressure and may help keep it within a healthy range (33).
SUMMARY:Potassium helps keep blood pressure within a healthy range. Increasing your intake of potassium-rich foods like cabbage may help lower high blood pressure levels.
7. Could Help Lower Cholesterol Levels
Cholesterol is a waxy, fat-like substance found in every cell in your body.
Some people think all cholesterol is bad, but it’s essential for the body’s proper functioning.
Critical processes depend on cholesterol, such as proper digestion and the synthesis of hormones and vitamin D (36Trusted Source).
However, people who have high cholesterol also tend to have an increased risk of heart disease, especially when they have elevated levels of “bad” LDL cholesterol (37Trusted Source).
Cabbage contains two substances that have been shown to decrease unhealthy levels of LDL cholesterol.
Soluble fiber has been shown to help lower “bad” LDL cholesterol levels by binding with cholesterol in the gut and keeping it from being absorbed into the blood.
A large analysis of 67 studies showed that when people ate 2–10 grams of soluble fiber per day, they experienced a small, yet significant, decrease in LDL cholesterol levels of roughly 2.2 mg per deciliter (38Trusted Source).
Cabbage is a good source of soluble fiber. In fact, around 40% of the fiber found in cabbage is soluble (39).
Cabbage contains substances called phytosterols. They are plant compounds that are structurally similar to cholesterol, and they reduce LDL cholesterol by blocking the absorption of cholesterol in the digestive tract.
Increasing phytosterol intake by 1 gram per day has been found to reduce LDL cholesterol concentrations by as much as 5% (40Trusted Source).
SUMMARY:Cabbage is a good source of soluble fiber and plant sterols. These substances have been shown to reduce LDL cholesterol.
8. Cabbage Is an Excellent Source of Vitamin K
Vitamin K is a collection of fat-soluble vitamins that plays many important roles in the body.
These vitamins are divided into two main groups (41).
- Vitamin K1 (phylloquinone): Found primarily in plant sources.
- Vitamin K2 (menaquinone): Found in animal sources and some fermented foods. It is also produced by bacteria in the large intestine.
Cabbage is a terrific source of vitamin K1, delivering 85% of the recommended daily amount in a single cup (89 grams) (2).
Vitamin K1 is a key nutrient that plays many important roles in the body.
One of its main functions is to act as a cofactor for enzymes that are responsible for clotting the blood (41).
Without vitamin K, the blood would lose its ability to clot properly, increasing the risk of excessive bleeding.
SUMMARY:Vitamin K is critical for blood clotting. Cabbage is an excellent source of vitamin K1, with 85% of the RDI in 1 cup (89 grams).
9. It’s Very Easy to Add to Your Diet
In addition to being super healthy, cabbage is delicious.
It can be eaten raw or cooked and added to a wide variety of dishes like salads, soups, stews and slaws.
This versatile veggie can even be fermented and made into sauerkraut.
In addition to being adaptable to many recipes, cabbage is extremely affordable.
No matter how you prepare cabbage, adding this cruciferous vegetable to your plate is a tasty way to benefit your health.
