Several newbie points:-
The top foods that cause the biggest problems for RVAFers are(roughly in descending order) :- raw dairy, raw veggie-juice, raw eggs and coconut oil/cream . Try eliminating 1 of those foods at a time for a month or two each time, to see if things improve. Also, eating too much in the way of raw foods is a bad idea. Raw foods contain more nutrients than cooked foods so, actually, you don't need to eat as much when going raw.Plus, many RVAFers have discovered that they heal faster during those times when they are not eating, which is why many people go in for various forms of Intermittent Fasting(ie either 1 large meal every day, or 1 large meal every alternate day).
Many RVAFers report that having some raw organ-meats in the diet helps speed up one's recovery(raw organ meats contain more nutrients than raw muscle-meats, and for those with severely wrecked digestive systems after decades on cooked diets, raw organs can often be more easily digested than raw muscle-meats as they are usually much softer and have a higher water-content. Raw organ-meats are also much cheaper as far fewer people like them among SMD-eaters.
Go in for raw 100% grassfed meats at all costs. If you can get hold of raw wild game (such as is often found at LFM farmers' markets in London http://www.lfm.org.uk/ , then that's even better/healthier(and considerably cheaper, oddly enough if you buy it from farmers' markets instead of those hideously expensive wild game butchers).
I go in for pretty much any kind of raw wildcaught fish as long as it's got more flesh than bones in it. I avoid farmed fish like the plague with the sole exception of eating raw sushi with acquaintances(sushi only provides farmed salmon, which is foul stuff). Don't buy "sashimi-grade" fish ever, as it's always far too expensive, just visit the fishmongers and get freshly caught raw wildcaught fish. I go in for things like raw swordfish/mackerel/shark/tuna/sardines/sprats/kingfish/scallops/mussels/oysters/prawns etc. etc. Probably best to avoid prawns, actually, as they are , I suspect, to some extent farmed nowadays, but farmed shellfish has a better reputation than farmed fish.
One thing that really works re improving digestion is "high-meat". However, this is usually only recommended for people who've been rawpalaeo for a year, as people are expected to get used to , and enjoy the taste of, raw meats, first. If you're willing to try it, though:-
