Bananagirl,
I really think food combination would help for you... At least it is something not costing anything to try :)
I have had stable poop for over a month now by experimenting with food combination, but the latest days I have been a little bit mixing ingredients against the rules, and today I had some blood in the poop and it was loose again.
At least one thing is sure: Food combining is reducing the gas and makes you able to keep the poop inside even if you have diarrhea.
The rules are easy to follow for an vegan:
1. Don't mix fruits with anything else.
2. Soy, peanuts and nuts should not be combined with anything else than non starchy items (all seeds, grains, potatoes are forbidden). Lettuce or any salad and non starchy vegetables are good to soy, peanuts and nuts. Nuts are also much better absorbed if they are soaked. Soaking removes stuff from the peel that is preventing digestion.
3. Starchy ingredients can be combined with any non starchy vegetables, salads or lettuce.
4. Melons are not normal fruits and they do not combine with anything else. If you can stand melons at all, eat them as a separate meal.
5. Avoid adding oils, and use only what is absolutely needed. The nuts and seeds you are eating are already having much fats, the same with avocados etc. Flax-seed is also a very good source for fat (omega-3). All added oils makes it more difficult for the enzymes to break down your food, and also added oils are usually having much omega-6, which causes inflammation.
Try to have only 3 regular meals. Give the stomach the rest it needs between. If you google for food combining rules, you will find many different variants. Some put nuts in the "go with anything" category, but my sensible stomach is apparently not happy with it.
I bought this book secondhand cheap (1 cent + shipping):
www.amazon.com/Food-Combining-Nutshell-Kathryn-Marsden/dp/0007140444/ref=sr_1_2?ie=UTF8&qid=1338183263&sr=8-2It made food combining much easier for me to understand. It is a very tiny book (surprisingly tiny), just containing the very basics... But that also makes it easy to read. It makes it a bit easier to categorize the food. I recommend.
Hopefully you get better soon!! :)
