What is Uric Acid?
Uric acid is an antioxidant. Its antioxidant property enables the body to protect itself against free-radical molecules that are associated with several diseases such as cancers.
Uric acid is generated in the body as a result of breakdown of purine in the liver.
When uric acid level in the blood is high, it has side effects. Uric acid eventually crystallizes, especially at low temprature. Uric acid crytals make their way to the joints, such as the big toe, ankle, and knees, causing gout. Other diseases associated with high blood uric acid include kidney stones, diabetic acidosis, acute alcoholism and leukemia.
Causes of High Serum Uric Acid
Uric acid accumulates in tissues and the blood when one consumes foods high in purines. Foods high in purines include meat and meat products and some vegeterian food stuffs, even though with lower levels. Other factors associated with high blood uric acid levels include starvation and consumption of foods high in fructose, fat and protein.
Foods and Uric Acid Content
In the following table is a list of food stuffs and estimates of their uric acid content. Foods high in uric acid content are listed at the top of the table while foods with low uric acid content are at the bottom. Fruits and vegetables have generally reduced level of uric acid. Meat products, especially internal organs are known to have, generally, higher levels of uric acid.
|Food source of uric acid||uric acid level(mg of uric acid /100 g food)|
|Mungo bean seed||222|
|Chicken (breast with skin)||175|
