Eating high oxalate foods daily and for extended periods of time, can cause a build up of oxalic acid in the body tissues, bones, organs, blood vessels, skin, and dramatically irritating nerves. It is considered a hidden medical problem resulting in what is referred to as soft neurology complaints without objective findings. It does not show up on blood / urine lab test or imaging studies. In severe cases in will be the culprit of Kidney Stones (calcium-oxalate stones).
In the future I will add further comments.
