Gout is a very painful arthritic condition, the base cause of which is purines in the diet. As purines are a by-product on anaerobic respiration, brewing yeast is a primary source in contemporary diets. The NHS links like the one below don't mention beer nearly as much as they might, because the yeast from fermentation is removed in almost all commercial beers. It is present in all homebrews to a greater or lesser extent and I would advise against drinking obviously cloudy, yeasty beer for that reason.
