Why tomatoes are linked with kidney stones?
There are several types of kidney stones and the most common one is calcium stones. These stones are formed due to the deposition of a large amount of calcium oxalate in our kidneys. Oxalate is a naturally occurring substance that is found in different kinds of vegetables and fruits. Moreover, even our liver produces certain amount of calcium daily. Our bones and muscles do absorb calcium from the blood, but when the amount of this nutrient exceeds in the blood, it is passed on to the kidney to be flushed out with urine. Some times the kidneys are not able to remove excess calcium from the body, which gradually starts to accumulate and takes a shape of a stone.
Tomatoes contain high amounts of oxalate and hence is linked with the formation of kidney stones.
The truth
If you love adding tomatoes in your food then you must not stop doing to because of this myth. Tomatoes do contain oxalate, but the amount of it is quite low and cannot lead to the formation of a kidney stone. 100 grams of tomatoes contain only 5 grams of oxalate. If tomatoes were so harmful then people diagnosed with kidney stones would have been advised to completely shun its consumption. If you are healthy and have no kidney issue then it is fine to have tomatoes as much as you like. In case you are dealing with some kidney related problem then limit your oxalate intake. Spinach, beans, beetroot also contain a high amount of oxalate. Cook these vegetables properly before eating.
