Every now and then a culture adds a grain to its diet. Sometimes corrections and adjustments are made, but not in a hundred years and perhaps it's time to question the 1920s wisdom of pre-molecular biology science.
America's obesity and mental health crises have common cause: poor diet mostly from industrial processing of food. We add chemicals to food t prevent people from dying, but we only add enough to prevent death, we do not add the amount require for optimal health - and let's be clear here these two levels, while different, and still both in homeopathic amounts. Oddly enough we learned this from animal care, stressed pigs don't taste good and sick guinea pigs don't work well in lab tests. We give guinea pigs more vitamin c than soldiers in the army, the care sheet for these animals is 1 gram a day, for a soldier its 75 milligrams, up from 30 a level established decades ago. Unless we give large (not homeopathic but therapeutic) doses of the B vitamins so animals like pigs and rats they become psychotic and kill each other.
This issue needs or be placed on the table and will be until people will no longer put up with the ill mental and somatic health caused primarily by industry.
