Vinegar

For gout, plain vinegar (e.g., white, apple cider, balsamic, red wine) is **safe to eat** in normal culinary amounts. Vinegar is extremely low in purines and does not directly raise serum uric acid. Some research suggests that acetic acid (the active compound in vinegar) may modestly improve insulin sensitivity and post-meal glucose response, which could indirectly help uric acid management by reducing insulin resistance. Apple cider vinegar is popularly touted as a gout remedy, but clinical evidence is weak for any direct uric-acid-lowering effect. It is harmless in moderation (e.g., 1–2 tablespoons per day in salad dressings or diluted as a drink), though undiluted vinegar can irritate the esophagus and tooth enamel. There is no evidence that vinegar triggers gout flares. Overall, it is a gout-friendly condiment, but it should not replace standard urate-lowering therapy such as allopurinol.
