However, what many people don’t realize is that eating cabbage the wrong way or in excessive amounts may cause health issues for certain individuals.
Overconsumption or improper use of cabbage can aggravate acid reflux, increase the risk of recurring kidney stones, interfere with iodine absorption in people with hypothyroidism, or reduce the effectiveness of anticoagulant medications.
Who Should Be Careful When Eating Cabbage?
1. People Taking Anticoagulant Medication (Warfarin)
Cabbage contains high levels of vitamin K, which plays a role in blood clotting. Consuming large or inconsistent amounts of cabbage may reduce the effectiveness of Warfarin.
Recommendation: There’s no need to completely eliminate cabbage, but intake should remain consistent from week to week so doctors can properly adjust medication dosage if needed.

2. People With a History of Calcium-Oxalate Kidney Stones
Cabbage contains oxalates, compounds that can bind with calcium in the urine and contribute to stone formation.
Recommendation: Avoid eating cabbage too frequently and drink plenty of water to help dilute oxalate levels in the body.
