It is not diet being rich, but many other factors from the diet. I was told to avoid beef and started eating turkey. Gout got worse. Turns out turkey was worse than beef. Acids from fruits is often what is the trigger for gout victims. For me, it is tomato.Gout is not anything like inflammation. It is the deposition of uric acid in joints. Thus it induces arthritis-like symptoms.
It was thought that a rich diet caused it, but this has been largely debunked and now it is thought that genetics is more important, sort of analogous to cholesterol.
