A low purine diet is a dietary principle that should be strictly adhered to by patients with hyperuricemia, but there are no specific foods that can lower blood uric acid levels. Uric acid is the end product of purine metabolism and is mainly produced by the enzymatic breakdown of nucleic acids and other purine compounds from cellular metabolism and purines from food. It is mainly from dietary control and the combination of medication to bring down uric acid. Diet: Foods with low purine content can be consumed, such as most vegetables, fruits, dairy products, rice and noodles, which have low purine content and are suitable for daily consumption. However, high purine diet into should be avoided, such as seafood, animal offal, thick meat soup, beer, white wine, yellow wine, etc. Moreover, since patients with hyperuricemia are prone to combine chronic diseases such as fatty liver and diabetes, their daily diet should be adjusted according to their weight, blood lipids and blood sugar level in addition to adhering to the principle of low purine. For example, in addition to a low purine diet, patients with combined diabetes should not consume too much staple foods such as rice and noodles, and in addition to a low purine diet, patients with combined hyperlipidemia should not consume too much fatty foods. And you should drink a lot of water to dilute the uric acid in the blood and increase the excretion of uric acid. If the uric acid level is not reduced to normal through dietary modifications, medication should also be administered. The main medications to lower uric acid include: drugs that promote uric acid excretion such as benzbromarone, drugs that inhibit uric acid production such as allopurinol and febuxostat, alkaline drugs such as sodium bicarbonate, and new uric acid-lowering drugs such as selective uric acid reabsorption inhibitors. Therefore, for patients with high uric acid, a low purine diet and plenty of water can play a role in lowering uric acid. For patients with hyperuricemia that cannot be controlled by diet, uric acid-lowering medication should be administered under the guidance of a clinician.
