Diet is the main source of exogenous purines and uric acid in gout patients, and uric acid is mainly from the breakdown of nucleotides in the diet. It accounts for about 20% of the total uric acid in the body. For hyperuricemia, endogenous metabolic disorders are more important than exogenous factors. If blood uric acid is high and purines are high, gout forms a reaction chain. Therefore what you can't eat and what you can eat when you have gout is quite important, and patients must be sure to pay attention to the gout diet at the same time as the gout treatment.
