What is a low-purine diet? A low-purine diet is a meal plan based on foods that are low in purine content. Purine is a substance that is found in foods and is produced naturally by the body. Purines are broken down by the body and changed to uric acid. The kidneys normally filter the uric acid, and it leaves the body through the urine. However, people with gout sometimes have a buildup of uric acid in the blood.
When you digest purines, your body produces uric acid which can build up into urate crystals in your joints. By reducing the amount of purines in your diet you lower the amount of purines your body must process. 1  Eat less red meat like steaks. 2  Donât eat gamey meats like rabbit, pheasant, and venison.
