Introduction
Fermented soybeans (douchi) generally have a relatively high purine content. Typically, the purine level in 100g of douchi ranges between 75–150mg. Normally, foods containing more than 100mg of purines per 100g are considered high-purine diets; therefore, douchi is regarded as high in purines. Consequently, individuals with elevated uric acid levels may experience further increases in uric acid after consuming douchi, potentially triggering an acute gout attack.

Generally, fermented soybeans (douchi) have a relatively high purine content, so patients with gout are usually advised against consuming them to avoid worsening symptoms and delaying recovery. The detailed analysis is as follows:

Under normal circumstances, the purine content in 100g of douchi typically ranges between 75–150mg. When the purine content in 100g of food exceeds 100mg, it is considered a high-purine diet. Therefore, douchi is regarded as high in purines. For patients with elevated uric acid levels, consuming douchi may further increase uric acid levels, potentially triggering an acute attack of gout.

It is recommended to strictly limit intake of high-purine foods and combine dietary control with appropriate physical exercise to maintain body weight within a normal range, which generally helps prevent gout.
