@Ken_Barker @strudball you both have my sincere sympathy. I used to suffer greatly from gout and could never find the trigger.
However, looking at this reference I notice alcohol listed, as well as other factors but not Marmite unless the salt content is a hidden factor.
Thankfully, my bouts of gout have diminished in recent years and I can’t help but think that giving up alcohol and reduced weight with careful type 2 diabetes management without insulin have all contributed to this outcome. (I do have some of the other medicaments mentioned though…)
I do hope so as the disease is incredibly debilitating
