I have found that if one has slow/sluggish digestion, meat can be hard to digest and lead to other issues. But that isn't because of the meat, usually, but because of slow digestion. Many people with diminished ability to produce enough gastric acid, for example, have this issue. Support digestion, keep endotoxin lower, and inflammation low, eat easy to digest foods, support the bodies healthy methylation system (which is important for proper digestion), etc. And, of course, one would want to eat good quality meat, if possible. Perhaps, while trying to do these things and get digestion in order, eat low PUFA white meat for the time being. Copper and Zinc is also very important.
