As someone who has always had a problem with calcium oxalate stones, I did not know peanut butter is so loaded with oxalates, so this is good information to have.
It’ll sound counter intuitive, but one way to avoid problems with oxalates is to consume calcium rich foods with oxalate high foods. For example, a glass of milk (soy milk counts) with a PB&J.
The reason this works is the calcium binds with the oxalate in your stomach and not your liver/kidneys.
For this to work, you have to consume both at the same time.
Something that’s always stuck with me (re:kidney stones) is that consistently sleeping on the same side seems to increase the likelihood of developing them.
In the 93 patients [of 110] who consistently slept to one side, the side in which renal stones were found was identical to the dependent sleep side in 76%. source
