During the 20th century, the Green Revolution transformed agriculture, ushering in new technologies that dramatically boosted food production. Among these advancements, pesticides became a staple in modern farming. While they helped create a surplus of food, there are concerns that pesticides have corroded the environment, contaminating the food supply and harming the neurological health of the very farmers who rely on them.

A recent article revealed a troubling link between pesticide exposure and depression among Brazilian farmers. Those who worked primarily with glyphosate reported significantly higher rates of depressive symptoms compared to those with less exposure. This study also adds to the growing body of evidence linking pesticide use to a range of health issues, including Parkinson’s disease, birth defects, Alzheimer’s, congenital malformation, cancer, and depression.

A team of researchers examined the gut-brain connection in relation to pesticide exposure and proposed that the correlation between pesticide use and mental health disorders could be explained by the disruption of gut health. Conditions like irritable........
