New Study Links Monsanto’s Roundup To Autism, Parkinson’s and Alzheimer’s

Glyphosate is a major component of Monsanto’s Roundup herbicide. Glyphosate was manufactured by Monsanto and is one of the most widely used herbicides around the world. A number of scientific studies surrounding glyphosate have shed light on its effects within the human body. It’s responsible for triggering health problems like gastrointestinal disorders, diabetes, heart disease, obesity, Parkinson’s and Alzheimer’s disease.

When you ingest Glyphosate, you are in essence altering the chemistry of your body. It’s completely unnatural and the body doesn’t resonate with it. P450 (CYP) is the gene pathway disrupted when the body takes in Glyphosate(3). P450 creates enzymes that assist with the formation of molecules in cells, as well as breaking them down. CYP enzymes are abundant and have many important functions. They are responsible for detoxifying xenobiotics from the body, things like the various chemicals found in pesticides, drugs and carcinogens. Glyphosate inhibits the CYP enzymes. The CYP pathway is critical for normal, natural functioning of multiple biological systems within our bodies. Because humans that’ve been exposed to glyphosate have a drop in amino acid tryptophan levels, they do not have the necessary active signalling of the neurotransmitter serotonin, which is associated with weight gain, depression and Alzheimer’s disease.
