Anecdotal evidence has suggested that purine-rich foods can trigger gout attacks.
Animal sources of purines such as meat and seafood were associated with a higher risk than plant sources such as
beans, peas, lentils, spinach and asparagus. Other major dietary sources of purines include yeast and alcohol.
The study is published in the Annals of the Rheumatic Diseases.
Researchers conclude that avoiding animal sources of purines could reduce the risk of recurrent gout attacks.
