Acetaminophen as a cause of the autism pandemic? It makes absolutely no sense … at first.

My research looks at what causes harmful inflammation in people in Western societies. The triggers of inflammation are recent developments in human history, appearing after the agricultural revolution only 10,000 years ago. Most did not appear until just a few decades ago, as we entered the post-industrial age. 1 My favorite example is the loss of biodiversity from the human body. Humans have always been bathed inside and out with bacteria, viruses, fungi, worms, and other organisms, but in recent decades our bodies’ ecosystems have become much less diverse, to our detriment.
