Currently, glyphosate (the main ingredient in Roundup) is the most commonly used herbicide within the U.S.  And, for those who don't know, this weed killer was patented back in the 1970s by Monsanto – one of the most hated corporations in the world.  Today, the sales of this herbicide are responsible for about half of the company's revenue each year.

In the past, glyphosate has been linked to liver disease and kidney problems in animals.  But one new study, which is the first of its kind, found that the ingredient has adverse effects on the human liver.

Conducted by researchers at the University of California San Diego School of Medicine and published in Clinical Gastroenterology and Hepatology, lead researcher Paul J. Mills wanted to find out if it was exposure to the herbicide glyphosate contributing to liver disease.

This recent study took a look at the amount of glyphosate found in the urine samples of two groups of patients – one group had nonalcoholic steatohepatitis (NASH), a type of nonalcoholic fatty liver disease, and the other group had no liver disease.  No matter the ethnicity, age, BMI, or race, the group of patients who had NASH showed a significantly higher amount of glyphosate residue in their urine.
