I became really interested in this a while back after watching a fascinating BBC documentary about fasting. It stated that cancer could not grow in the absence of IGF-1 (a growth hormone secreted in response to protein ingestion). I did a bunch of research and found barely anything out there about it, but the little I found did seem to back it up. I recommend anyone interested in this topic watch this film, it's great: http://www.dailymotion.com/video/xvdbtt_eat-fast-live-longer-hd_shortfilms#.UbXtVvnV98E http://www.dailymotion.com/video/xvdbtt_eat-fast-live-longer...
