Glutathione, Nrf2, Autism and glyphosate
Glyphosate use has escalated (1) at a similar rate and overlapping time frame to the increase in autism in children. The rate of autism in Japanese children is even greater than in U.S. children. The Japanese children may be consuming a larger percent of GMO soy from the U.S. as the country is a significant importer of the crop. (4)Testing has shown that basically all GMO soy, Roundup Ready, has residue of glyphosate. (1) Glyphosate residue has been found in all foods tested by the FDA except for broccoli. (6)
The herbicide Roundup has been shown to induce oxidative stress in animal studies (5), and children with autism have been shown to have an increase in oxidative stress and reduced levels of an antioxidant, glutathione, (2), that is made within our bodies during normal health.
Use of Nrf2 promoting foods might help increase our own production of glutathione. (3) Broccoli is one food that may help promote our own supply of Nrf2 which then helps us make the antioxidant glutathione.
Glyphosate may be metabolized into other chemicals within the body and it or the metabolites may inhibit enzymes important for a variety of functions throughout the body. (7) Radioactive labeling of glyphosate in animal studies by the company Monsanto showed that bioaccumulation of the chemical does occur, particularly in blood cells found in bone and bone marrow, also in the testes and ovaries, see slide 11 for a copy of the table of data: (8).
A thorough overview of the theoretical and known health risks of glyphosate is available by a personal fitness coach from Australia, Alex Fergus, (9), in part two of a three part series on his website. Part one covers the history of the synthetic chemical's discovery and patent history and increased agricultural use in the U.S. and globally, (10), and his list of tips on how to protect yourself and try to reduce exposures through diet and supplements, (11). The list is comprehensive however doesn't include Epsom salt/magnesium sulfate as an additional source of bioactive sulfate. Baths or footsoaks provide a topical absorption route that would bypass any problems with malabsorption in the digestive system or problems with sun exposure to bioactivate other forms of sulfur into the bioactive sulfate form.
