That doesn't make much sense because by drinking juice, you're absorbing all the nutrients instantly. It's usually said that unhealthy and nutrient deficient people don't absorb all the nutrients in their food (even if raw) anyway.
I am sorry; I don't think I made myself clear. A cancer patient is usually very thin. They need the calories that food provides.
Then of course you have your other experts that say not to. You could go to some kind of holistic doctor/proffessional and the advice would still be contradicting. How do you decide what to do.
Listen to your body. This is indeed a personal choice.
