Jyy2 - I also agree with Dr. Fam's comments about a low-purine diet having little benefit for gout. In this article, Dr. Fam also suggests a reduced-calorie low-carbohydrate diet for benefiting insulin resistance syndrome (irs), which is a precursor to diabetes, both of which have a very strong association with gout. The intent of his low-carb diet recommendation is to reduce weight, which he expects will reduce the symptoms of both irs and gout. Dr. Fam does not mentioned the strong connection of irs to sleep apnea, which is well-recognized in medical literature. Perhaps he correctly expects that losing weight will reduce sleep apnea too.
But in my own case, I was never overweight, and I had both irs and gout. Now that I have resolved my sleep apnea, I no longer have either one of them. Diet was irrelevant.
