V8 is full of salt and other additives, and it has been heated (pasteurization), and so it is NOT raw food. If you were to make the juice yourself from scratch with a vegetable juicer, it would taste very, very different than a bottle of V8. Vegetable broth is one way to help get your system used to vegetable juices (cut up & cook a bunch of veggies in a pot full of water; strain off the broth & discard the veggies; drink the broth in 8-oz servings as you are able to ~ this is healthy, is not contrary to any food pyramid or regular diatetic recommendations unless you have kidney disease, and can boost your mineral intake quite a bit). If a person has food allergies or sensitivities (non-IgE or non-immune "reactions" to foods), then the choice of fruits & veggies to juice would have to be specifically adjusted to accomodate the specific needs of the individual. And it is not good to start with a full-sized glass of juice if a person isn't used to eating vegetables or fruits in any sizeable amount - it is better to start out with an ounce or two at the most and slowly get used to drinking more as tolerated. And if it doesn't work, it doesn't work. Not everything works for everyone. Just my $.02.
