Do tomatoes cause kidney stones?

I had oxalate kidney stones twice, and my nutritionist told me that while tomatoes contain oxalates, the amount is actually very low. I didn't have to stop eating them entirely, I just reduced the seeds and kept myself very well hydrated.

I literally just got discharged last week after passing a kidney stone. My urologist told me that the seeds of tomatoes have some oxalates, but they are not the main culprit. Drinking less water and eating too much salt is what usually causes it.

At my age, every WhatsApp forward tells me a new vegetable is going to kill my kidneys. Tomatoes are fine, folks. Just don't eat ten of them raw everyday, and keep drinking water like your life depends on it—because your kidneys certainly do!

I completely understand how anxious you must be feeling about this, especially with all the myths floating around. Rest assured, tomatoes have very little oxalate content compared to spinach or nuts. It is highly unlikely they will cause stones on their own.

Drinking fresh lemon water daily is a great home remedy to prevent stones. You can eat tomatoes, but maybe discard the seeds if you are prone to stones. However, if you have severe side pain or blood in urine, please see a doctor immediately.
