I asked the question about why I have had no intestinal complaints from drinking raw sourdough milkshakes and eating the dry raw sourdough chips. I asked this on August 19, 2020. Since then, I have been researching if PHYTIC ACID might be reduced in the sourdough environment. I am not certain that low pH has any negative effect on PHYTIC ACIC. I'm not going to post my entire blood chemistry nutrient profile but I now suspect I am not absorbing all the nutrients I should. PHYTIC ACID is known to bind many important nutrients making them unavailable for uptake in the small intestines. Therefore I am stopping drinking sourdough milkshakes as now I think they are harming my health. It is wiser to get extra Vitamin B12 by taking supplements.
