Blog Talk Radio. They started in January 2013. I was impressed enough by the content, I broke down and bought an iPod so I could download the shows and lay in bed and listen to them. So you don't feel obligated to listen to all of them and feel overwhelmed, the best ones so far one the one on the the SNPs that I linked to, and one from Ben Lynch on how vitamins are manufactured. I'm currently listening to the one on Down's Syndrome and MTHFR which is pretty interesting. There are other topics such as thyroid and hormones, fluoroquinolone toxicity and so forth that may interest other people.
