Thank you Kevin. I had heard that about bananas, and we have told my dad to start eating them, but sometimes he's a pain-in-the-neck about stuff like that. I will definitely get on that. He's finally drinking more water than before, and now drinking Gatorade too -- although not as much as he should. (However, every week when he goes to the docs for his treatment, i make sure they give him the hyrdration fluids, etc to replenish).
Best of luck in your journey and wishing you positive energy.
