I have been doing a lot of research on the effects of nutrition on the treatment of cancer. Two books that I found on Amazon I would highly recommend and both books say sugar is a no-no.
The first book is "Beating Cancer With Nutrition" by Patrick Quillin, PHD, RD, CNS and the second is "The What To Eat if You Have Cancer" by Maureen Keane, MS and Daniella Chace, MS. My advice is just go to Amazon.com and pull up these books and read the reviews concerning them. I have hopes that by following their recommendations I can slow down the progression of my lymphoma. God Bless and good luck to you and your wife.
