I haven't seen the movie but flagged as a " to do"
You have hit the nail on the head. Can I add one the symptoms of outpolled are abnormal fit flora, gut dysbiosis, IBS and food intolerances. Many of the puroluriacs I have met have hit problems.
50 % of alcoholics tested by Dr Walsh of Walsh institute ( over 20,000 people tested) have pyroluria. 40% of schizophrenia sufferers too. It also has high incidence in people suffering depression and anxiety. My husband is getting test as he has a strong family history in these areas and he has signs of low zinc, as well as brain fog - (I thought it was dopey husband stuff!)
The experts on this condition believe it to be one of the underlying reasons behind gut flora issues because b6 and zinc are required for over 200 enzymatic processes and for detoxification
Pathways, production of musin the line the gut and proper functioning of enterocytes in gut lining. Without b6 and zinc one will have lowered immunity and susceptible to infections and overgrowths such as parasites, candida, bacterial overgrowths etc. the role of diet is paramount in the treatment of pyroluria and the recommendation is usually something along the lines of the GAPS diet. But a pyrolle needs mineral and vitamin supplementation to fix the cause too.
