Let me chime in here and try to see if I can help you out.
The Paleo diet will not help you at all. It will only make your problems worse. We were not meant to eat a high fat high protein diet. We are starch eaters.
Our bodies produce Amylase in abundance compared to Protease or Lipase. That alone should be a good indicator on what you should be eating.
White rice is very healing to the gut, its easy to digest and provides energy to a weak body. It however is low in minerals and vitamins so you would need to eat an abundance of leafy greens and fruit in order to balance that out. Also beans are a good source of minerals.
Google the Mcdougall diet.
I would suggest eating the white rice before going into harder to digest grains such as brown rice.
Also as phytic acid goes, it is not a bad thing to have in our diets.
If you go to PubMed and look up phytic acid, you will see there are quite a few good things to read about phytic acid how it is beneficial to the body. I didn't believe it myself until I looked that up. Phytic acid is bascially the phytonutrient of a grain. And we are told that phytonutrients are made from fruits and vegetables to ward off bugs from eating them, but when these phytonutrients are in the human body they are beneficial to use. Makes sense that phytic acid does the same thing regardless if it binds to minerals. If you eat a balanced diet of leafy greens and fruits you wont be harmed at all.
Our ancestors lived off of starches and whole grains. If we didn't why are they so prominent now a days. They are only now starting to slowly go away, which doesn't make sense. But you the whole Paleo movement going on right now. I have tried Paleo and it made me feel worse and worse the longer I did it. I started 80/10/10 in the Mcdougall form and I havent felt better.

From Mcdougall's website:
* Research published in the journal Nature (on June 27, 2012) reports that almost the entire diet of our very early human ancestors, dating from 2 million years ago, consisted of leaves, fruits, wood, and barkóa diet similar to modern day chimpanzees.
* According to research presented in a 2009 issue of Science, people living in what is now Mozambique, along the eastern coast of Africa, may have followed a diet based on the cereal grass sorghum as long as 105,000 years ago.
* Research presented in a 2011 issue of Proceedings of the National Academy of Science shows that even the Neanderthals ate a variety of plant foods; starch grains have been found on the teeth of their skeletons everywhere from the warm eastern Mediterranean to chilly northwestern Europe. It appears they even cooked, and otherwise prepared, plant foods to make them more digestibleó44,000 years ago.
* A 2010 issue of the Proceedings of the National Academy of Science reported that starch grains from wild plants were identified on grinding tools at archeological sites dating back to the Paleolithic period in Italy, Russia, and the Czech Republic. These findings suggest that processing vegetables and starches, and possibly grinding them into flour, was a widespread practice in Europe as far back as 30,000 years ago, or even earlier.
