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)
