19. High-Purine Foods: The Gout and Kidney Stone Connection
Purines are substances found in many foods that can be broken down into uric acid in the body. High levels of uric acid can lead to the formation of gout and kidney stones.
Gout is a type of arthritis that causes pain, swelling, and redness in the joints. Kidney stones are hard deposits that can form in the kidneys and cause pain in the lower back, side, or groin.
High-purine foods include organ meats, such as liver and kidney, anchovies, sardines, herring, mackerel, and other fatty fish. Other high-purine foods include gravy, broth, bouillon, yeast, and alcohol, especially beer.
While all purine-containing foods can contribute to the formation of gout and kidney stones, some are higher in purines than others. It is recommended that people who are susceptible to gout or kidney stones limit their consumption of high-purine foods.
On the other hand, low-purine foods, such as fruits and vegetables, dairy products, and most grains, are considered safe for people with gout or kidney stones. In addition, it is important to drink plenty of water to help flush out uric acid and prevent the formation of stones.
To protect your kidneys, it’s important to limit your intake of high-purine foods and choose lower-purine alternatives, such as lean poultry, fish, and plant-based protein sources. By making mindful dietary choices, you can reduce the risk of kidney stones and support overall kidney health. (19)
