Your gout is an interesting puzzle where all the usual pieces don’t fit when they usually go. The only thing I can think of is metabolite concentrations are too high because you’re eating too often. Gout as a general condition isn’t exclusively caused by uric acid, though that is the most common culprit. I also wonder if it isn’t caused by something in your water? Personally I would change all my dietary routines drastically one at a time until I found the source of the problem. It might take a while, but gout can be a lifetime lasting painful problem. Worth it!
