Is caffeine or glyphosate (the active ingredient in the herbicide Roundup) more toxic to mammals?
As detailed in an academic book published by the American Society for Microbiology, it takes more than 10 times the weight of glyphosate to kill rats than it does caffeine. Likewise, multiple studies have found that substances with low immediate toxic effects generally have low cancer-causing effects. Many people fail to understand that a "fundamental principle" of toxicology is that "the dose makes the poison," and all substances can be toxic or benign, depending upon their doses. A 2019 survey published in the journal "Nature Chemistry" found that 76% of Europeans falsely believe that "being exposed to a toxic synthetic chemical substance is always dangerous, no matter what the level of exposure is."
