You do need to cut down or avoid some foods
. Those that
I know of that
can contribute to the formation of calcium stones
are strawberries, beetroot, peanut butter. I can't remember other foods, but I am sure there were some more.
I do find that if I eat too much peanut butter, I start to feel uncomfortable in my kidney area.
Once you have had kidney stones (apart from the Cystine ones which are hereditary) you will be prone to getting them again.
