Uric acid in your body usually forms as a waste product of eating foods high in purines. Meats are rich in purines, but other foods also contain them. For most people, uric acid does not cause a problem because their kidneys flush it out. For others, it can cause two painful ailments: gout and uric acid kidney stones. When you have too much uric acid in your body and your kidneys do not get rid of enough of it, it can solidify into crystals in your joints and cause inflammation and pain, known as gout. It also can solidify into small, hard “stones” in your kidneys that cause pain upon their exit. Generally, fruits are low in uric acid-producing purines. Ask your doctor or nutritionist about a low-purine diet to avoid uric acid problems.
When you eat raisins, you are eating a fruit with higher levels of purines. Fruits in general fall into the middle and low ranges of purine-containing foods, having far less uric acid production possibilities than most meats and fish. Still, Sultana grape raisins contain approximately 107 milligrams of uric acid per 100 grams of fruit.
The apricot is one of the highest purine-containing fruits. Apricots contain approximately 73 milligrams of uric acid per 100 grams of fruit. This still is low compared to high-purine foods such as organ meats and fish such as anchovies or sardines, which can have 200 to 300 milligrams in 100 grams. Still, if you have problems with high uric acid levels in your body, you may want to avoid apricots.
Plums and prunes also have relatively high levels of purines. As fresh fruit, plums contain approximately 24 milligrams of uric acid per 100 grams of fruit. When you dry plums to make prunes, you increase the uric acid levels to 64 milligrams per 100 grams of fruit. So, as a fresh fruit snack, plums do not pose much of a uric acid problem, but can be problematic as dried fruit. However, at 64 milligrams, plums rate much lower than most meats.
As fresh fruit, bananas have lower purine levels than plums. A 100 grams of banana has roughly 57 milligrams of purines.Think twice about dipping bananas in chocolate, because theobromide, a substance in chocolate can set off alarms. Theobromide clocks in at the highest level of uric acid of any food at 2,300 milligrams per 100 grams of the substance.
In the fall, consider limiting your intake of pumpkin pie if you have an intolerance for uric acid buildup. While pumpkin is comparatively low in purines next to many types of animal-derived foods, among fruits, pumpkin contains more purines, 44 milligrams per 100 grams, than other fruits such as dates, strawberries and apples. Eating a couple of pieces of pumpkin pie may not cause you a problem, but indulging in a lot of it could bring on kidney stones or a gout attack.
