High blood uric acid levels suggest not consuming fish products such as yellow bone fish. Purine components ingested in food can be converted into uric acid in the body. The purine content of aquatic products such as yellow-bone fish, cod, squid and mussels is usually more than 100mg/100g. For people with high blood uric acid levels, consuming the above foods will aggravate the abnormal uric acid levels and is not conducive to the recovery of uric acid levels. For transient elevation of blood uric acid level caused by food or other reasons, blood uric acid level can be restored to normal by increasing water intake and adhering to a low purine diet; if the blood uric acid level remains at a high level for a long period of time, it is necessary to intervene by using drugs to inhibit the production of uric acid, such as febuxostat, or by promoting the excretion of uric acid, such as phenylbromalone. If blood uric acid level is abnormal, it is recommended to consult a doctor in time, and drugs should be used under the guidance of clinicians, avoiding unauthorized use of drugs.
