4 Types of People Who Should Avoid Eating Too Much Cabbage

Cabbage is packed with fiber, vitamins C and K, and powerful antioxidants, making it one of the healthiest vegetables around. But while it’s a great choice for most people, there are certain situations where eating large amounts of cabbage may not be the best idea.
Here are four groups of people who should be cautious.
1. People with Thyroid Disorders
Raw cabbage contains natural compounds called goitrogens, which may interfere with iodine uptake when consumed in very large amounts. For most people this isn’t a problem, but individuals with hypothyroidism—especially those with low iodine intake—may benefit from eating cabbage cooked rather than raw and enjoying it in moderation.
2. People Who Frequently Experience Bloating or IBS
Cabbage is high in fiber and contains fermentable carbohydrates (FODMAPs), which can cause gas, bloating, and abdominal discomfort in some people, particularly those with irritable bowel syndrome (IBS). Cooking cabbage often makes it easier to digest.

3. People Taking Blood-Thinning Medication
Cabbage is rich in vitamin K, a nutrient that plays an important role in blood clotting. If you take medications such as warfarin, suddenly increasing or decreasing your cabbage intake can affect how the medication works. The key is to keep your vitamin K intake consistent and follow your healthcare provider’s advice.
4. People Recovering from Certain Digestive Surgeries
After some stomach or intestinal surgeries, doctors may recommend a temporary low-fiber diet. Because cabbage is high in fiber, it can be difficult to digest during recovery. Always follow the dietary plan provided by your medical team.
The Bottom Line
For most healthy adults, cabbage is a nutritious food that can be enjoyed regularly. The important thing is moderation and knowing whether you have a medical condition that requires extra caution. If you’re unsure, speak with your healthcare provider or a registered dietitian before making major changes to your diet.
