124 - Why was Red Dye No. 3 banned in the US?

Why did the FDA ban the use of Red Dye No. 3 and why is it still available in Canada? Guest co-host Pedro joins Dr. Chris Labos to explain and discuss how we should think about food colourings in general. Does the fact that can cause cancer in rats mean anything for human health? And what about the alleged ADHD link? Also, there’s a Winnie the Pooh reference at the end. Become a supporter of our show today either on Patreon or through PayPal!
