Joe Rogan on glyphosate: what the evidence says · JRE #1999
SUBJECT: GLYPHOSATE
The short answer
Rogan claims a recent study found roughly 90 percent of Americans tested had detectable glyphosate in their blood. The most comprehensive biomonitoring data available comes from the CDC's National Health and Nutrition Examination Survey (NHANES) for 2013-2014; peer-reviewed analyses of that dataset report glyphosate was detectable in the urine, not the blood, of about 81 to 82 percent of the U.S. population aged 6 and older (n=2,310).
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
one of the things I noticed when there was a test that came out or a study that came out recently that showed that an enormous percentage of Americans, it was somewhere in the 90 percent range when they were tested, had glyphosate in their blood.
What the evidence says 01 / RECORD
Joe Rogan stated that a recent study found glyphosate in the blood of roughly 90 percent of Americans tested. The most comprehensive biomonitoring data available comes from the CDC's National Health and Nutrition Examination Survey (NHANES) for 2013-2014; peer-reviewed analyses of that dataset report glyphosate was detectable in the urine, not the blood, of about 81 to 82 percent of the U.S. population aged 6 and older (n=2,310). Glyphosate has a short biological half-life, on the order of hours to a few days, and is cleared mainly through urine, which is why biomonitoring programs measure urinary rather than blood concentrations. Detection at these trace levels indicates exposure, not necessarily harm, and the NHANES analyses do not by themselves establish adverse health effects at the levels measured in the general population. Rogan's approximate percentage is in the neighborhood of the nationally representative NHANES figure, but he attributes the finding to blood testing when the underlying biomonitoring measured urine; smaller, non-representative convenience-sample projects have reported somewhat higher percentages, adding to the confusion around the exact figure.
