1. People With Thyroid Conditions (Especially Hypothyroidism)
Cabbage contains goitrogens, natural compounds that can interfere with thyroid function by blocking the body’s ability to absorb iodine. This can be a problem for people with underactive thyroid (hypothyroidism) or other thyroid disorders.
- Why it matters: Goitrogens can affect the production of thyroid hormones, which regulate your metabolism, energy, and more.
- What to do: Cooking cabbage can reduce goitrogens significantly. If you have a thyroid issue, it’s best to eat cooked cabbage in moderation rather than raw, and keep your iodine levels in check.
2. People With Irritable Bowel Syndrome (IBS) or Sensitive Digestion
- Why it matters: Raw cabbage, in particular, can be very rough on sensitive stomachs and may trigger cramps or diarrhea.
- What to do: If you have IBS or frequent bloating, try small amounts of fermented cabbage (like sauerkraut), which is sometimes easier to digest. You can also opt for low-FODMAP vegetables instead.
3. People Taking Blood Thinners
Cabbage is rich in vitamin K, which plays a key role in blood clotting. While that’s normally a good thing, it can interfere with anticoagulant medications like warfarin (Coumadin).
- Why it matters: A sudden increase in vitamin K can reduce the effectiveness of blood thinners, putting you at risk for blood clots or stroke.
- What to do: If you’re on blood-thinning medication, talk to your doctor before adding cabbage (especially in large amounts) to your diet. The key is consistency in your vitamin K intake—not avoiding it entirely.
4. People With a History of Kidney Stones
Cabbage contains oxalates, compounds that can contribute to kidney stone formation in people who are prone to them, especially calcium oxalate stones—the most common type.
- Why it matters: Although cabbage isn’t the highest-oxalate vegetable, regular consumption can still be a concern if you’re susceptible to stones.
- What to do: Drink plenty of water, moderate your intake of high-oxalate foods, and consult your doctor or dietitian if you’ve had kidney stones in the past.
