Patients with gout who consumed high levels of purine-rich foods — including meats, organ meats, seafood, lentils, spinach, mushrooms, yeast, and beer — over a 2-day period increased their risk of flare almost five-fold, a case-crossover study showed.
What are purines and in which foods are they found?
Purines are natural substances found in all of the body's cells, and in virtually all foods. The reason for their widespread occurrence is simple: purines provide part of the chemical structure of our genes and the genes of plants and animals. A relatively small number of foods, however, contain concentrated amounts of purines. For the most part, these high-purine foods are also high-protein foods, and they include organ meats like kidney, fish like mackerel, herring, sardines and mussels, and also yeast.
