What Are Purine Foods?

What Are Purine Foods?

Purines are present in every human cell. They're also present in every food we eat, but only a handful of foods have them in significant amounts. Eating high purine foods, says the George Mateljan Foundaton, can be a health risk for some people.

Effects

    Gout has plagued humans for centuries.

    High purine foods can raise blood levels of uric acid. Excessive uric acid may form crystals in the tendons and muscles, causing an inflammatory condition called gout.

Types

    A 1986 to 1998 study headed by Massachusetts General Hospital found that plant purines have no effect on uric acid levels. Fish and meat proteins raise them. Dairy purines may lower them.

High Purine Foods

    Very high purine foods include anchovies, organ meats, and sardines with more than 1000 mg of purines in a 3.5 oz. serving. Dietitians recommend 150mg of purines daily for gout sufferers.

Moderate Purine Foods

    Foods with 5 to 100mg of purines in a 3.5 oz. serving include beef, pork, poultry, fish and shellfish. Asparagus, peas spinach lentils and kidney beans are moderate purine vegetables and legumes.

Considerations

    Cooking food may change its purine content, according to a 1987 study at the Munich Technological University. Boiled veal and other meats released some of their purines into the water.
