I think your observation is still valid Bob, sugar is taken up more readily by the cancer cells than the normal tissues.

At the risk of another roundy-round, the subject of sugar is rather simple to me: There is no reason I can find to purposely maintain a higher than normal blood sugar level. Refined sugar was nearly absent from our early ancestors and they did just fine. Current day cultures that eat similar simple diets exhibit lower rates of several types of cancers. If there is even a small chance that elevated blood sugar levels help cancer to survive or thrive then why eat more sugar?

With regard to Vegetarian diets, most competant nutritionists would tell you that vegetarian diets are generally more healthy. Where I differ is I see a significant need for very high protein intake because of the massive tissue repair going on during radiation treatments. Vegetarian diets are usually not high protein. In addition, many essential fats are also important.

Colored fruits and plant materials are also a rich supply of many many nutrients, vitamins and minerals. Certainly boosting the supply of every kind of nutrient would be beneficial during the treatment procedures we go through. Plant fiber is one of the best ways to deal with constipation. I won't go on and on.

I was easily able to eliminate most "added" sugar from my diet and suffered no ill effects from doing so.

Lastly, Eric My experience with hospital nutritionists is similar to what you have described. Mostly they are concerned with calories and hydration. They didn't seem to care at all about how you get the calories or much else. My grand "conspiricy" theory is that there are few "official" studies about nutritional adjuncts and cancer because there is no money to be made by doing the studies.
