Marvin,
You are so right. Sorry for the delay in responding. I began with "Beating Cancer with Nutrition" by Paul Quillin. Very informative and author is knowledgeable with good credentials. My two complaints were that the recommendations were general, ie: you should take this and that, but not specifically how much "this and that" and at what frequency. My second is that for me, I had already done the chemo thing and was not going back. The author mixes both traditional and nutritional therapies. But for your friend's grandmother, this might be the right approach. I especially liked the author's strong stand against refined Sugar and he has an excellent guide and glucose scale. This helped open my eyes to alternatives. Thanks for caring about this lady.
Regards,
FC
