Well, Djr-81, I think, mentioned had some food-intolerance to raw, grainfed meats, but was fine on raw, grassfed meats(I think even a little grain-feeding caused isuses?)
I definitely have a high sensitivity to grain in an animal's diet.
Interestingly Haii I have differing reactions to red meats.
Beef and venison, provided they have not been eating grain or corn, sit fine.
Goat tastes good but when eaten more than a couple meals binds me up and leaves mucus in my bowel movements.
Lamb gives me very loose unpleasant stools and stomach distress.
I don't like bison so haven't experimented much with it.
I have various reactions to seafood as well.
I've been diagnosed, through blood tests, with allergies to many non-fish seafoods. Those that I have tried, such as scallops, since eating RAF have sat better than cooked but resulted in allergic reactions.
Swordfish sits fine.
Mako Shark was fine.
Tune seems to sit fine as well but I don't enjoy most varieties.
I've tried a couple white fishes and these cause some mucus in the stool.
I encourage you to diversify your diet and find the meats that sit well. I do not have personal experience with fruitarianism but I skew to moderation in general and a diet based on one food group doesn't seem ideal in the long run (I eat RZC myself and have been trying to expand my diet towards a more omnivorous approach myself).
