Instruct: Classify Amazon reviews into positive or negative sentiment
Query: the mother of all conspiracy theories

this book contains a few useful guidelines about healthy eating and living but then goes on to rally against tap water , toothpaste , microwaves and every medication or drug ever invented.. also endless requests to subscribe to a web site to get more information from a man who claims to be uninterested in money ... a bit hypocritical and possibly dangerous for those who choose to believe the information contained without critical thought
