Gout and diet advice. The higher your uric acid, the greater your risk of developing gout. Beer, hard liquor, and organ meats such as liver are particularly bad for gout. You can find low purine diets on line, but a slightly high uric acid level probably isn't a big deal, unless you have a strong family history of gout or kidney stones.
Red meat. There are multiple causes for high uric acid. Need to reduce red meat intake helps to lower uric acid. May need medication like allopurinol. Please check with your doctor.
