The U.S. govt. legislated the fortification of bread flour with niacin beginning in 1938. I suspect the protocols have been relaxed (the amount of niacin reduced). Niacin deficiency symptoms include psychosis, neurosis, insomnia, depression, melancholia, schizophrenia & anorexia nervosa. The children of the West today are the most heavily-medicated children on Earth for psychosis, neurosis, insomnia, depression, melancholia, schizophrenia & anorexia nervosa. There aren't new diseases so much as there are symptoms of old diseases re-branded as new diseases to be marketed by drug companies. Case in point: anorexia nervosa (food aversion) = classical symptom of pellagra (B3 deficit) & (to a lesser degree) beriberi (B1 deficit). The preventative, treatment & cure for insomnia and mental illnesses (including the diseases: anorexia & pellagra) is niacin (vit. B3). The thiamine/vitamin B1 deficiency disease beriberi also entails food phobia (anorexia). Research Dr. Abram.
