Although the content of purine in tomato is not high, it contains more glutamic acid, which can provide raw material nitrogen for purine synthesis and easily increase the synthesis of uric acid in human body.

Phenolic acids contained in tomatoes can also inhibit the excretion of uric acid by the kidneys, which leads to the increase of uric acid and gout.

Therefore, it is suggested that patients with hyperuricemia and gout avoid eating a lot of tomatoes.
