Cabbage is very healthy for most people, but it’s not ideal for everyone. Here are 4 types of people who should avoid—or be cautious about—eating cabbage, especially in large amounts:
1. People With Thyroid Disorders (Especially Hypothyroidism)
-
Cabbage is a goitrogen, meaning it can interfere with iodine uptake.
-
Large amounts of raw cabbage may worsen thyroid function.
-
Tip: Cooking cabbage greatly reduces this effect. Moderate portions are usually fine if your thyroid condition is well-managed.
2. People With Digestive Issues or IBS
-
Cabbage is high in FODMAPs, which can cause:
-
Bloating
-
Gas
-
Abdominal pain
-
-
Raw cabbage is especially hard to digest.
-
Tip: Try cooked cabbage or fermented forms (like sauerkraut) in small amounts.
3. People on Blood-Thinning Medications
-
Cabbage is rich in vitamin K, which can interfere with medications like warfarin.
-
Sudden increases or decreases in intake can affect blood clotting.
-
Tip: Consistency matters—don’t dramatically change how much cabbage you eat without medical guidance.
4. People With Kidney Problems or Prone to Kidney Stones
-
Cabbage contains oxalates, which may contribute to kidney stone formation in susceptible individuals.
-
Not usually a problem in small amounts, but excess can be risky.
-
Tip: Balance cabbage with plenty of fluids and other low-oxalate vegetables.
