Jay Kordich "the juiceman" cured his bladder cancer with carrot and apple juice; I read it in his book. I am not a juicer, I only believe in blending, but there are properties in carrots and apples that can build the immune system so much that even juicing it can cure cancer. It's powerful stuff. Carrots do not raise blood sugar much according to the glycemic load (not the old index they used to think was accurate). I would still blend them to get the fiber and slow the absorption rate down a bit. If I had cancer, I might juice some, too in order to get enough, because carrots (and apples) are harder to blend than some things, but when you do blend them, you can add water.
