There is a substance on approximately seventy percent of the non-organic produce in American grocery stores right now. You cannot see it. You cannot smell it. You cannot taste it. And if you ask most people whether they are concerned about it, they will either say they have heard it is fine or admit that they do not know much about it at all. This is Episode 68 of The Bitter Truth About Food, and we are going to spend the next hour talking about pesticides — what they are, what the evidence actually says about their effects on human health and the environment, and what you can do about it.

This is not a simple story with a villain and a hero. The use of pesticides in agriculture is bound up with one of the most consequential challenges of the modern era: feeding more than eight billion people on a finite amount of arable land. Pesticides have played a real role in preventing crop failures that would have caused genuine starvation. That is not propaganda. It is history. But the honest accounting of pesticides has to include both sides of that ledger, and the side that gets systematically underreported — the chronic health effects, the environmental consequences, and the regulatory failures — is the side we are going to examine today.
