The “volumes” refer to a series of DVDs (now digital only) upon which is based (all proceeds donated to charity). The DVDs give folks the opportunity to sneak preview videos months ahead of time, watch them all straight through, and share as gifts, but there’s nothing on the DVDs that won’t eventually end up online free here at

Volume 4 covers the peer-reviewed scientific nutrition literature published between spring 2009 and spring 2010.

Note that the video snippets from volumes 1-4 were ripped from pre-existing DVDs before existed, and so were created without the web experience in mind (so are not only lower production quality but often have abrupt beginning/ends). Sorry about that! One of these days I’d like to redo all these old ones but alas am lucky to just keep my head above water (posting new videos and articles every day!)
