Gout disease, as we often call it, is now a prevalent disease among middle-aged and older people and has long been a concern. Controlling blood uric acid levels is the key to gout treatment. In the minds of the people, once you have gout, you basically can’t eat anything. However, is a purely vegetarian diet sufficient to lower uric acid? The question that comes up starts with the source and destination of blood uric acid. The source of uric acid in the blood is 20% from food and 80% from metabolism in the body. The route of uric acid in the blood is mainly through the excretion of the kidneys. It is first filtered through the glomerulus, then reabsorbed, re-secreted, and re-secreted after reabsorption in the proximal tubule. Studies have shown that the clinical typing of hyperuricemia in the population includes only 10% of increased production and 90% of impaired excretion. Therefore, the reduction of uric acid should be controlled not only to reduce the source of uric acid in the blood but also to increase the excretion of uric acid. Even a purely vegetarian diet only controls 20% of these sources and has a limited effect on reducing uric acid in the blood. In 90% of the types of renal excretion disorders, enhancing excretion should be the key to treatment. In addition, as the standard of living has improved and people have become accustomed to a life of “luxury food”, there are difficulties in implementing a purely vegetarian strategy. A purely vegetarian diet can only partially solve the problem in uric acid treatment. The misconception that “pure vegetarianism can lower uric acid” is the current misconception of gout uric acid treatment.
