Cabbage is generally a healthy food and most people do not need to avoid it. Headlines claiming that four groups must never eat cabbage are usually overstated.
Four situations where caution may be appropriate are:
-
People taking warfarin — cabbage is rich in vitamin K, which can affect warfarin. Usually the goal is consistent intake, not complete avoidance.
-
People who develop significant bloating or gas from cabbage — cabbage can ferment in the gut and may worsen symptoms. Smaller portions or cooked cabbage may be better tolerated.
-
People with a cabbage allergy — uncommon, but allergic reactions mean cabbage should be avoided and medically evaluated if symptoms are significant.
-
People with certain thyroid disorders — cruciferous vegetables contain goitrogenic compounds, but normal dietary amounts are generally considered safe. Cooking reduces these compounds further. People with thyroid disease generally don’t need to eliminate cabbage unless their clinician advises otherwise.
Bottom line: There isn’t good evidence that four broad categories of people should completely avoid cabbage. The appropriate advice depends on the person’s condition and medications.
If you have thyroid disease, take warfarin, or have another specific condition, tell me which one and I can explain whether cabbage is appropriate for you.
