Dont forget that you coudl be eating high ox yet not get immediate symptoms. Oxalate overload is not the same as other sensitivities. THe other ones are dependent of lack of enzymes. Whereas oxalates is a slow build up and you may not experience a sudden reaction .. not until you start to go low enough in oxalates so that the body reacts in an immediate way.
A person like me with oxalate problems can be making the oxalates in my own body so that previous to doing supplemental p5p and thiamine my levels were never coming down. WIht adding in p5p , 35 years of kidney/ bladder ecoli problems went away..
That would make sense about the oxidative level being involved .. I used to have nausea all the time. I stopped having nausea after eliminating all of my food sensitivities.. ie salicylates, amines, dairy, gluten,and finally oxalates two years ago . I was forced to eat only a few foods for the past two years. Not considering parasities again until now.
I had begun to have nausea just at certain times of the day.. ie 4:30 until around 10 am . I had found that supporting my HPA axis using homeopathy and also taking epsom salts soaks had remedied that for some time.. Until a month ago I went on vitamin K and from there on in the nausea and horrible gut problems were back at night. When I am trialling a supplement which my body could not break down I would go into what I termed these oxidative stress modes.
I had done parasite cleanses using herbs as well as drugs previous to going off of all food senitivities and also going low oxalate diet , but had had no results..I had contineud with bad nausea, fevers, sweats fatigue.. ie liver stress . Now after doing those other food protocals I just started to take diatomaceous earth three days and so far wonderful results but for the drying/ constipating affect.
