It's not that you can't eat vinegar. Vinegar is an acidic substance. However, patients with hyperuricemia need to alkalize their urine to reduce uric acid and slightly alkalize the body's pH value, which means keeping it on the alkaline side within the normal range. In such cases, it is recommended to eat more alkaline foods. Alkaline foods facilitate the excretion of uric acid through urine and help lower blood uric acid levels. Of course, this does not mean that you cannot eat vinegar at all; you can consume it in moderation, but not excessively.
