Gout is a form of arthritis caused when the body has an excess of uric acid. Uric acid works to break down purines in the body. It can begin to build up when the body produces too much of it, the kidneys do not process it efficiently, or too many purines are consumed.
What Are Purines?
Purines are part of the chemical structure of the body’s genes and are naturally present in the tissue of the body. They are also part of the chemical gene structure of plants and animals. The amount of purines found in most plants and animals consumed by humans is relatively low and do not pose a risk of gout. The foods that contain concentrated amounts of purines are those that increase the risk of gout.
Legumes and Purines
Some legumes contain concentrated levels of purines placing you at greater risk for gout. Beans have so many nutritional benefits these should not be taken out of the diet but merely consumed in moderation. The following beans average between 100-400 mg uric acid/100g:
