I have!! love them. A good place to start for beginners a documentary called 'Fat, Sick and Nearly Dead', a book called 'Crazy, Sexy, Diet' which is full of great information about food and what we put into our bodies. You can follow the diet if you wish, i never did but it was a great book to motivate and educate. On Facebook look up a guy named Tyler Tolman, his father is Don Tolman one of the worlds best 'natural' doctors who has healed and cured many people around the world of sickness, including cancer through fasting and changing their diets . Hope that helps xox
