High uric acid should be limited to soy products. Soy products are medium purine foods and should not be eaten if uric acid is not under control. If the uric acid can be controlled within the normal range, then you can eat it. The specific cause of high uric acid is not yet fully understood, and some studies have shown that it may be related to a variety of factors such as genetics, diet, and exercise. The normal blood uric acid level in people is 180-420μmol/L, and higher than 420μmol/L is called hyperuricemia. Long-term hyperuricemia may lead to gouty arthritis, and hyperuricemia is also an independent high-risk factor for cardiovascular disease, so it is usually important to keep blood uric acid within the normal range to reduce the probability of these organic lesions.
