Any high-protein food such as cheese can cause gout.
It is the organic nitrogen -- present in all amino
acids -- which causes gout. Pound-for-pound.
purine-rich foods generate more nitrogenous waste
because purines also have organic nitrogen, but
it is certainly possible to have a gout attack
triggered solely by diet, even if that diet is
purine-free. Cheese and eggs are major hazards
to avoid with regard to gout.
