My husband is just starting radiation (finished day 7 of 31 treatments). I bought the book mentioned above ("Beating Cancer with Nutrition") a few weeks ago and noticed that it had a recipe for a "Dragonslayer milkshake" that seemed pretty nutritional. He had the peg inserted before radiation began and I was thinking this would be a good thing to make when the time comes. I don't like the ingredients of Ensure/Boost either (sugar, corn syrup and vegetable oil mainly). Now, while he's having no trouble eating, he does have a daily shake made of ice cream, soy milk, and a powdered soy based vitamin supplement. Also, I noticed that Dr. Andrew Weil has recommended (on his website) that cancer patients take a mushroom blend extract and milk thistle during radiation/chemo. Also, he recommends astragulus. I ordered both in pill and liquid form.
