What is in spinach that causes kidney stones?

My mother used to tell me to limit spinach because she said it could cause kidney stones. I love spinach, so I'm curious what specific thing in it might be responsible for that.

Spinach is packed with oxalates, which can bind to calcium in your urinary tract and form calcium oxalate stones. My tracking app always flags high-oxalate foods, so I make sure to boil it well to reduce the levels.

The culprit is oxalic acid, which makes calcium stones in people who are prone to them. Please don't self-diagnose or cut out greens completely, get a doctor to check your urine and kidney health first.

It has oxalates, and I learned this the hard way after a severe kidney stone attack last year that required a procedure. Please see a urologist or a dietician to get a proper diet chart instead of guessing.

It’s oxalates, apparently. Honestly, I’m too tired dealing with midnight insomnia to worry about spinach, but I guess boiling it or eating it with some paneer helps lock that calcium.
