This is part of why I couldn't be vegan. Nuts, raw or otherwise, give me terrible, painful stomach cramps for over a day. The pain is as intense as a kidney stone (I know, I've had a couple).
I'm also allergic to soy and olives (though I can use the oil, just not eat the flesh).
Try being a raw vegan with no nuts, no soy, and no legumes (which give me cramps also, though not quite as bad). I CAN eat peanut butter--but only cooked. I can't eat lima beans, garbonzo beans, kidney beans, chickpeas (but can eat regular peas), and I can't eat uncooked carrots. Carrots, in point of fact, are one of the worst foods for me as far as putting my stomach into sheer agony.
The problem with a lot of the people who push vega/tarianism in whatever form is that they don't take into account the fact that every body isn't the same. If you can't digest half of the needed foods, you're just not going to thrive. I was miserable the entire time I was raw vegan because I was in continual pain and I was faint and dizzy. Couldn't stand up without swooning and having to wait for the blackness to pass.
With almost every kind of eating lifestyle/diet, I think there are bodies that just don't handle it well. When we as human beings start understanding this, and looking at each body as an individual, rather than thinking they're like all the same exact brand and make of car... then we may well begin to find genuine health. But it almost seems like everyone thinks that "what works for me works for everyone, PERIOD."
I somewhat envy those who can do raw vegan and thrive. But I cannot, and denying it for so long made me quite sick. I honestly wonder if my current teeth problems are a product of doing that to myself for so long. Although I know for certain that I was horrifically malnourished as a child and literally got only dog food to eat with the rare bit of ham, bacon, or other "treat" (like the dogs) sometimes. Perhaps it is related to that, but I have my suspicion that trying to force my body to accept a lifestyle that it couldn't thrive in had at least as strong an impact.
You can't fight your body. You just cannot win, because your body doesn't give in, it just gives out.
