20. Tuna

There really is no limit as to how much or how little of purine rich foods you can eat everyday if you suffer from gout. It’s a matter of personal tolerance, which you can figure out by keeping tabs on what you ate just before suffering an attack. Canned tuna has been found to contain 290mg of purine per 100g, quite low compared to other foods but still capable of causing an attack of gout in people with low tolerance levels
