Some people think if kidney stones arise from consuming too much fiber, both from fruits and vegetables. This assumption is a myth. Fiber does not make the body produce stones in kidney organs. Precisely the case that often occurs, the trigger of kidney stones is high levels of uric acid in the body.
Disclosed by Dr. Hardianto Setiawan Ong SpPD as a specialist disease at Siloam Hospitals, excessive uric acid is often triggered by the intake of protein foods. In protein foods are often found high purine levels. This is what further increases uric acid levels.
However, in certain types of vegetables are also known to have high purine levels. For example, broccoli and cabbage. Therefore people with the uric acid disease are often asked to avoid this type of vegetable.
“Too much consumption of vegetables such as broccoli and cabbage can cause uric acid,” said Hardianto, as quoted from the page Republika.
On the other hand, the formation of kidney stones can also occur due to the reaction of calcium and oxalate that meet in the kidney. Disclosed by Professor Dr. Y. Marsono as a researcher from the UGM Food and Nutrition Laboratory, the meeting between calcium and oxalate produces calcium oxalate. It looks like a salt crystal with a pointed tip surface.
“It will cause tremendous pain in the kidneys,” said Marsono.
For vegetables, the type that has high oxalate content one of them is spinach. If someone is known to have a habit of taking high doses of vitamin C supplements, it is also likely to have excess oxalate in the body. The reason, the metabolism of vitamin C will produce oxalate. A long-term meeting between oxalate and calcium can lead to the formation of kidney stones.
“If the activity is too much, high-dose vitamin C is needed. If under normal conditions, should take vitamin C as needed, or from fruit and vegetables. That’s enough,” said Marsono.
