Can eating beans or nuts cause gout?

Beans yes : Beans more so than nuts also meat mushrooms sea food lentils are not so bad.

Maybe: Some beans and nuts have high levels of purines, the precursors of the uric acid that causes gout. However, the effect of vegetable purines on gout seems to be less than those that come from meat. The best strategy in the long run is to eat a healthy, balanced diet and to take any prescribed medications for gout on a regular basis.
