You probably hear about it in the news or on social media on a yearly basis: the "Dirty Dozen" list of pesticide-contaminated foods you'd best avoid. 

They assure you this list is made up of the most dangerous, disease-causing fruits and veggies due to their greater-than-average synthetic chemical contamination.

But just where is this ranking coming from? Are toxicologists and other scientists weighing in, or is it just a bunch of yokels with a spreadsheet? 

In today's episode of the Renaissance Humans Podcast, I talk to Toxicologist Carl Winter, who has spent much of his career investigating what pesticide residues do to humans. 

He's published a critique of the methodology used in the Environmental Working Group's "Dirty Dozen" list in the peer-reviewed Journal Of Toxicology, and tells us what he thinks of it. 

We also talk about what sort of threat pesticides pose to humans, whether or not organic food is worth your cash, and where he thinks money should be spent in improving the safety of agriculture and human health.
