That headline is exaggerated. There are no universal “4 types of people who should never eat cabbage.” Cabbage is generally safe and healthy for most people, but a few groups may need to limit it or be cautious depending on their health.
Here are the real situations where cabbage might cause issues:
1. People with thyroid problems (especially iodine deficiency)
Cabbage is a cruciferous vegetable and contains natural compounds called goitrogens.
- In very large amounts (especially raw), these may interfere with iodine use in the thyroid.
- This is mainly a concern if someone already has untreated iodine deficiency or certain thyroid conditions.
Cooked cabbage reduces this effect significantly.
2. People with digestive sensitivity (IBS or gas issues)
Cabbage is high in fiber and fermentable carbs, which can cause:
- Bloating
- Gas
- Abdominal discomfort
This is common in people with irritable bowel syndrome (IBS) or sensitive digestion.
3. People prone to kidney stones (in some cases)
Cabbage contains oxalates in small amounts.
- Usually not a problem in normal diets
- But people with a history of calcium oxalate kidney stones may be advised to moderate high-oxalate foods overall (cabbage is not among the highest, though)
4. People taking blood-thinning medication
Cabbage contains vitamin K, which affects blood clotting.
- If someone is on medications like warfarin, sudden large changes in vitamin K intake can affect dosage control.
- It doesn’t mean “no cabbage,” just consistent intake is important.
🥬 Bottom line
For most people, cabbage is:
- Healthy
- Nutrient-rich (fiber, vitamin C, antioxidants)
- Good for digestion and heart health
Problems only come from specific medical conditions or very large amounts, not from normal eating.
If you want, I can also tell you whether raw or cooked cabbage is better for digestion and weight loss—there’s a big difference people usually miss.
