I personally found, early on in the diet, that ground/minced meat digested less well than meat in chunks - don't know why, exactly.
There has been a lot of concern among Primal Dieters re the issue of veggie-juices:- for one thing mixing veg and meat together in the same meal is not a good idea re food-combination rules(they require different types of stomach-acid) but also veggie-juice contains antinutrients, so that, if one drinks them too regularly, they tend to cause problems.
Other than issues with raw dairy/coconut-oil and the like(to which I'm allergic), I have had the occasional digestive upset with raw meats - these generally occurred, though, due to mistakes on my part such as eating aged, raw meat which I hadn't left exposed to the air on a regular basis, or eating too much raw meat at one time. I'm not discounting the notion that it's a particular batch which is at fault, though. I take it, it's 100% grassfed?
