I retired from a chemical and pharmaceutical company, and have been exposed to many toxic chemicals, and even hospitalized 2 times for chemical exposure.
I did find this info on parkinson's:
Parkinson's Disease Linked to High Iron Intake.
People with high levels of iron in their diet are more likely to develop Parkinson's disease, according to a study in the June 10 issue of Neurology.
Iron and manganese contribute to oxidative stress, a situation where cells release toxic substances called free radicals as part of normal energy consumption and metabolism.
"Oxidative stress may cause degeneration of brain cells that produce dopamine -- the same cells that are affected by Parkinson's disease," said study author Harvey Checkoway, PhD, of the University of Washington in Seattle.
Will the orange juice fast help chelate the high iron and manganese in the body?
