Cabbage
Low calorie. High nutrition. When fermented, cabbage becomes a probiotic powerhouse — the Indian kanji tradition is supported by modern microbiome science.
TLDR — What You Need to Know
- Cabbage is 92% water and one of the most calorie-efficient vegetables — 100g provides only 25 calories with meaningful Vitamin C, K, and fibre
- Glucosinolates in cabbage convert to isothiocyanates (sulforaphane, indole-3-carbinol) when cells are damaged — these are the anti-cancer compounds
- Fermented cabbage (in Indian kanji, Korean kimchi, or European sauerkraut) develops live Lactobacillus bacteria — a potent probiotic food
- Sulphur compounds in raw cabbage juice are traditionally used for stomach ulcer relief — Vitamin U research supports this
- Always remove the outer 2-3 leaves — they are the most exposed to pesticides
- High FODMAP vegetable: cooked cabbage causes significant gas and bloating in IBS-prone individuals
What Is Cabbage?
Cabbage (Brassica oleracea var. capitata) is a leafy green, red, or white biennial plant grown as an annual vegetable crop. It is a member of the cruciferous family (Brassicaceae) and is closely related to broccoli, cauliflower, Brussels sprouts, and kale — all selective cultivars of the same wild ancestor, wild mustard (Brassica oleracea).
Cabbage has been cultivated in Europe for over 4,000 years and features in nearly every traditional cuisine in the world. In India, cabbage is used across all regions — from Karnataka’s cabbage palya (a dry coconut-tempered preparation) to North Indian cabbage sabzi, to raw cabbage in chaats and salads.
Three main types are grown and consumed in India:
- Green cabbage — the most common; smooth, pale green leaves with a firm, waxy head
- Red/purple cabbage — higher in anthocyanins; more antioxidants than green; slightly peppery flavour
- Savoy cabbage — crinkled, darker green leaves; milder flavour; less common in Indian markets
The stalk or core of the cabbage is edible and nutritious — it contains concentrated glucosinolates and is often discarded unnecessarily.

Health Benefits
1. Glucosinolates and cancer prevention
Like all cruciferous vegetables, cabbage is rich in glucosinolates — sulphur-containing compounds stored in vacuoles within cells. When cells are damaged (by chopping, chewing, or fermentation), glucosinolates contact the enzyme myrosinase and convert to biologically active isothiocyanates, including sulforaphane, indole-3-carbinol (I3C), and 3,3-diindolylmethane (DIM).
Indole-3-carbinol is particularly significant in cabbage. It influences oestrogen metabolism — promoting the conversion of oestradiol (E2) to the less potent 2-hydroxyoestrone rather than the more potent (and potentially carcinogenic) 16-alpha-hydroxyoestrone. This pathway is believed to contribute to the observed inverse association between cruciferous vegetable intake and hormone-sensitive cancers in epidemiological studies.
2. Vitamin K for bone and blood health
With 76µg of Vitamin K per 100g, a single serving of cabbage provides over 60% of the daily recommended intake. Vitamin K activates osteocalcin (necessary for bone mineralisation) and the clotting factors II, VII, IX, and X. Adequate Vitamin K intake is associated with better bone density and reduced fracture risk in observational studies.
3. Fermented cabbage as a probiotic
When cabbage is fermented in brine (as sauerkraut in European tradition, kimchi in Korean cuisine, or in Indian kanji tradition), wild Lactobacillus bacteria naturally present on the cabbage leaves begin fermentation, producing lactic acid and lowering pH. This creates a preserved, shelf-stable, probiotic-rich food with dramatically increased bioavailability of Vitamin C and other antioxidants.
The Lactobacillus plantarum strains dominant in fermented cabbage have been shown in clinical trials to improve gut barrier function, reduce intestinal permeability, and modulate immune responses. Fermented cabbage also contains Vitamin B12 at trace levels — produced by bacterial metabolism.
4. Anti-ulcer properties — Vitamin U
Cabbage juice has been used in traditional medicine across cultures for stomach ulcer treatment. The 1950s American physician Garnett Cheney documented dramatic healing of peptic ulcers with raw cabbage juice (1 litre daily) in a clinical case series. The active compound is S-methylmethionine, sometimes called Vitamin U (not a true vitamin), which stimulates mucin secretion and protects the stomach lining. While not a treatment for diagnosed peptic ulcers, the anti-ulcer mechanisms are real and support the traditional use.
5. Anti-inflammatory and low-calorie nutrition density
At 25 kcal per 100g, cabbage is one of the lowest-calorie vegetables while delivering meaningful Vitamin C, Vitamin K, folate, and fibre. For calorie-conscious diets, it provides extraordinary nutrient density per calorie. Its anthocyanins (in red/purple varieties) add anti-inflammatory activity. The fibre supports satiety and gut motility.
Side Effects and Who Should Avoid
Goitrogens: Like all cruciferous vegetables, cabbage contains goitrogens that can impair thyroid iodine uptake when consumed in very large quantities raw. Cooking deactivates most goitrogenic compounds. Normal dietary portions of cooked cabbage are not a thyroid concern. Those with diagnosed hypothyroidism should maintain consistent (not suddenly very high) raw cabbage intake.
High FODMAP: Cabbage is one of the higher FODMAP vegetables. Cooked cabbage is a significant trigger for gas, bloating, and abdominal discomfort in IBS patients. Fermented cabbage (where bacteria have pre-digested some of the fermentable carbohydrates) is often better tolerated.
Vitamin K and blood thinners: As with all Vitamin K-rich foods, those on warfarin anticoagulation therapy should maintain consistent cabbage intake. Sudden large increases can reduce warfarin’s anticoagulant effect.
Outer leaves and pesticides: The outer leaves of conventionally grown cabbage receive the most direct pesticide exposure. Always remove the outermost 2-3 leaves before washing and use. Washing alone does not remove residues from outer leaves.
Organic vs Conventional
Cabbage does not appear on the EWG Dirty Dozen — it typically has lower pesticide residue levels than many other vegetables. However, the outer leaves carry the most residue, and the practice of removing them before use is strongly recommended regardless of whether the cabbage is organic or conventional. For inner leaves after removal of the outer 2-3 layers, conventional cabbage is generally considered lower risk.
How to Select and Store
Selecting: Choose a cabbage that feels heavy for its size — this indicates high water content and freshness. The outer leaves should be tightly wrapped with no yellowing or brown spots. The cut stem end should be fresh-looking without drying or browning. Avoid cabbage with loose, wilted outer leaves or a strong smell.
Storing: A whole, uncut cabbage head stores well in the refrigerator for up to 1 month. Once cut, wrap tightly in plastic wrap or an airtight container and use within 3-4 days. Cut cabbage oxidises quickly — the edges will brown and Vitamin C will decline. Store whole as long as possible and cut only as needed.

Key Ingredients
300g green cabbage, finely shredded · 2 tbsp fresh grated coconut · 1 tsp mustard seeds · 1/2 tsp urad dal · 6-8 curry leaves · 2 dried red chillies, broken · 1/2 tsp turmeric · 1 tbsp coconut oil · Salt to taste · Squeeze of lemon juice to finish
Home Test: Artificial Colour Test for Red/Purple Cabbage
Steps
- 1 Cut a few outer leaves of the red cabbage
- 2 Soak the cut pieces in a bowl of plain cold water for 5 minutes
- 3 Observe the colour of the water — natural red cabbage will release a slight purple-pink tinge from natural anthocyanins
- 4 Now add a pinch of baking soda (alkaline) to the water and observe
- 5 Natural anthocyanins from red cabbage turn blue-green in alkaline conditions — this pH-shift test confirms authentic pigment
Pure / Pass
Water turns faint purple-pink. Upon adding baking soda, the water shifts to blue-green. This pH-sensitive colour change confirms the presence of natural anthocyanin pigments. Red cabbage is genuine.
Adulterated / Fail
No colour in water, or colour does not shift to blue-green with baking soda addition. Suggests the cabbage has been dyed with artificial colouring agents rather than having natural anthocyanin content.

Frequently Asked Questions
Q Is raw cabbage or cooked cabbage more nutritious?
Is raw cabbage or cooked cabbage more nutritious?
Both have distinct advantages. Raw cabbage preserves Vitamin C, active myrosinase enzyme (for glucosinolate conversion), and anti-ulcer compounds. Cooked cabbage deactivates goitrogens, improves digestibility, and reduces gas for people with sensitive guts. For maximum benefit: include both in your diet. A simple raw cabbage salad alongside a meal is a very different nutritional profile from well-cooked sabzi.
Q Does cabbage cause gas for everyone?
Does cabbage cause gas for everyone?
Not everyone, but it is a high FODMAP vegetable and cruciferous gas is common. The gas is produced by gut bacteria fermenting undigested carbohydrates (raffinose, fructans) in the colon. People with robust, diverse gut microbiomes often experience less gas than those with disrupted gut bacteria. Cooking cabbage significantly reduces gas-producing compounds. Fermented cabbage is usually the best-tolerated form.
Q Is purple cabbage significantly better than green?
Is purple cabbage significantly better than green?
Yes, in one important respect: purple cabbage contains anthocyanins — the same flavonoid pigments found in blueberries and red onions — in addition to the glucosinolates found in both colours. Anthocyanins are potent antioxidants with anti-inflammatory activity. For raw applications (salads, slaws), choose purple cabbage for the extra antioxidant profile. For cooked applications, the difference is less significant as anthocyanins are heat-sensitive.
Q Can cabbage juice help with stomach ulcers?
Can cabbage juice help with stomach ulcers?
There is historical evidence and some scientific rationale for this. S-methylmethionine (Vitamin U) in cabbage juice stimulates protective mucin production in the stomach lining. A clinical case series by Dr Cheney in the 1950s showed impressive ulcer healing with fresh cabbage juice. Modern medicine treats H. pylori-associated ulcers with antibiotics, but cabbage juice as a supportive measure is not contraindicated. Do not use it as a replacement for medical treatment.
