I don't really have anything to add other than I have experienced something similar, after eating a ton of blueberries and mostly raw animal products for about a week I've randomly developed IBS symptoms (irregular, difficult bowel movements, intestinal gurgling swelling and pain) and now that I'm back cooking my meats, I'm seeing undigested meat in my stool which is something I have never noticed before. It may well could have been there but I never inspected it close enough to see it. It feels like something in my digestion broke. I remember once after eating about 9oz raw lamb leg, 1oz raw butter and raw cheese my stomach started gurgling insanely loudly like I've never heard before. I really don't know what to do so I've just gone back to eating like I used to, just natural animal products, high fat, fruit and maybe veg without grains or anything, and the gurgling is not as intense. It sucks because I actually enjoy raw meat, but I don't know if I can or should eat it. It's really weird because I see all these people online who have great health success on raw foods whereas it seems like I just broke in response to raw meat and eggs. I've been on raw goats milk for the past 10 years and have had no issues so I don't think it's that.
