Dr. Stephanie Seneff, who made these remarks during a panel presentation in Groton, MA last week, specifically cites the Monsanto herbicide, Roundup, as the culprit for the escalating incidence of autism and other neurological disorders. Roundup, which was introduced in the 1970’s, contains the chemical glyphosate, which is the focal point for Seneff’s concerns. Roundup was originally restricted to use on weeds, as glyphosate kills plants. However, Roundup is now in regular use with crops. With the coming of GMO’s, plants such as soy and corn were bioengineered to tolerate glyphosate, and its use dramatically increased. From 2001 to 2007, glyphosate use doubled, reaching 180 to 185 million pounds in the U.S. alone in 2007.
If you don’t consume corn- on- the -cob or toasted soybeans, however, you are hardly exempt from the potential affects of consuming glyphosate. Wheat is now sprayed with Roundup right before it is harvested, making any consumption of non- organic wheat bread a sure source for the chemical. In addition, any products containing corn syrup, such as soft drinks, are also carrying a payload of glyphosate.
According to studies cited by Seneff, glyphosate engages “gut bacteria” in a process known as the shikimate pathway. This enables the chemical to interfere with the biochemistry of bacteria in our GI tract, resulting in the depletion of essential amino acids .
Monsanto has maintained that glyphosate is safe for human consumption, as humans do not have the shikimate pathway. Bacteria, however, does—including the flora that constitutes “gut bacteria.”
It is this ability to affect gut bacteria that Seneff claims is the link which allows the chemical to get on board and wreak further damage. The connection between intestinal flora and neurological functioning is an ongoing topic of research. According to a number of studies, glyphosate depletes the amino acids tyrosine, tryptophan, and phenylalanine, which can then contribute to obesity, depression, autism, inflammatory bowel disease, Alzheimer’s and Parkinson’s.
