4 Types of People Who May Need to Be Careful With Cabbage
Cabbage is a nutritious vegetable and most people do not need to avoid it. However, there are a few situations where eating large amounts—or suddenly changing how much you eat—may require caution.
People taking warfarin
Cabbage contains vitamin K, which affects blood clotting. If you take warfarin, you generally don’t need to eliminate cabbage, but you should keep your vitamin-K intake reasonably consistent and discuss major dietary changes with your clinician.

People with digestive sensitivity
Cabbage can cause gas, bloating, or abdominal discomfort in some people. If you have a sensitive digestive system, smaller portions and thoroughly cooked cabbage may be easier to tolerate.
People with certain thyroid concerns and inadequate iodine intake
Cabbage is a cruciferous vegetable and contains compounds that can interfere with iodine use. However, for people who get adequate iodine, eating reasonable amounts of cabbage is generally not considered a thyroid problem.

People who have been told to follow a special medical diet
If you have kidney, digestive, thyroid, or other medical conditions requiring dietary restrictions, don’t assume that an internet list applies to you. Your diet may need to be individualized.
Bottom line
For most people, cabbage is a healthy food, not something to fear. The biggest medication-related issue is consistency if you’re taking warfarin or a similar vitamin-K-sensitive anticoagulant. Don’t stop eating vegetables or change your diet dramatically without discussing it with your healthcare professional.
