What are Purines?
Purines are nucleotide bases found in plant and animal cells. Purines comprise adenine, guanine, hypoxanthine, and xanthine. They make up important components of the genetic materials, DNA and RNA, and energy molecules such as ATP, GTP and
coenzyme A. Therefore, purines are essential constituents of life.
Purine Rich Diet and Gout In the body, purines are metabolized to uric acid, for instance when cells die. Purines are among the factors that are causes of elevated
uric acid in the blood. With the consumption of high purine foods, serum uric acid may rise above the normal level. Even though uric acid acts as an
antioxidant and has a free-radical scavenging effect, when it accumulates to a high level in the blood it can cause gout and other health problems. Gout is a form of arthritis caused by the accumulation of uric acid in joints, especially in the big toe.
In a 12-year study that followed eating habits and gout incidence in large number of men it was found that eating food rich in purine, such as meat and seafood, was associated with high risk of gout, whereas a higher level of consumption of dairy products was associated with a reduced risk. Moderate intake of purine-rich vegetables or
protein was not associated with an elevated risk of gout.
