I like Hulda Clark books, very interesting stuff. There's also a good one called "The Grape Cure" which cures cancer, can't remember the author and not sure if it's available as e book. Norman Walker's juicing book is a classic, been in print a long time. Paul Bragg wrote some good books too, I'm sure you're familiar with The Master Cleanse by Stanley Buroughs...great quest you're on:)
