Although you avoid processed food, maybe you should consider them as medicine. There are many products out which are very good and are basdically plant based.

I had problems with soy/tofu products giving me terrible stomach cramps. Since I knew that I would be on a liquid diet after surgery I tried various products before I went in. I found that in addition to rice milk I could tolerate Vitasoy and it tasted good. Somehow since surgery, I can now enjoy tofu/ soy products. Maybe I had something which the weeks of antibiotics killed.

Most of the supplements are dairy and because I keep a level of Kosher which requires that all dairy products are supervised beginning with the milking of the cows I spoke with the dietician and found a non-dairy supplement. (look for the word Parve - it means do dairy or meat products.)

Try to increase sweets. There are "ice creams" which are non-dairy. Rice Dream and Tofuti have been around awhile and there are two new brands Good Karma and Decadent Delight which are gluten free and delicious(expensive, but delicious).

good luck
