Transcript: Preventing Parkinson’s Disease With Diet
Four things we can do that may reduce our risk of developing Parkinson's disease is exercise, avoid dairy products and pesticides, and avoid getting hit in the head, which means wearing your seatbelt and bike helmets. And, if you read journal articles written by medical researchers with way too much time on their hands, avoid getting attacked by extraterrestrials, a leading cause of traumatic brain injury in… comic books. What about avoiding pesticides and other industrial pollutants? A recent autopsy study found higher levels in the brains of Parkinson's victims of certain PCBs found in Monsanto's Aroclor, which was banned in 1979. And the more PCBs found in the brain, the worse the brain damage. The worse three appeared to be PCBs 138, 153, and 180, all of which are significantly lower in the bodies of those eating plant-based diets. So, does a vegan diet reduce risk of Parkinson's disease? Good question. Well we know that every single prospective study on "dairy products or milk" and Parkinson's disease found increased risk. And again it may be that dairy products in the United States are contaminated with neurotoxic chemicals. There's substantial evidence "suggesting that exposure to pesticides may increase Parkinson’s disease risk," and autopsies have found higher levels of pollutants and pesticides in the brains of Parkinson’s disease patients, and some of these toxins are present at low levels in dairy products. They're talking about toxins like tetrahydroisoquinoline, a parkinsonism-related compound found predominantly in cheese. Although the amounts of this neurotoxin—even in cheese—are really "not very high," the concern is that the chemical may accumulate in the brain over long periods of consumption.
