Interesting. I have noticed that sour meat doesn't bother me nearly as much as it used to, though more decayed meat that has a rotting smell and taste still does. I also noticed that in one of his TV interviews, Aajonus seems to enjoy the taste of his rotted foods. If rotted meat digests better than fresh, then that suggests to me that Stone Agers may have consumed it relatively frequently. Do you have any idea what proportion of traditional Inuit food was eaten as high/rotted?
I'm not really sure but it is noted by Stefansson et al that high meat(or rather high-fish) was a particularly coveted food. And then there are multiple other staples of the Inuit diet such as aged whale "high-meat"(aka "Muktuk"). As for Palaeos, except in Arctic areas, they had limited opportunity to freeze raw meats, so would have often have had to eat their meats in a partially-rotten state, at times, when game was plentiful.
One reason I thought that it might be better to start out slow with high meats, beyond the taste factor, is that modern cooked food eaters are prone to getting sick if their food is undercooked and contains some living bacteria (ie, "food poisoning"), whereas people who have been eating mostly or all raw for some time seem less prone to this. I thought perhaps they might be even more prone to GI discomfort initially if they went right to eating lots of raw, rotted meats bountiful in bacteria. In other words, it seemed to me like it might not give their intestines sufficient time to transition to a different biotic culture.
Well, eating rotting, aged cooked wild gamebirds was a common practice among the English upper classes and they seem to have thrived on it. And then there's the Inuit on their partially-cooked diets who seemed to be OK on raw high-meat. For my part, I've found that my usual detox effects from cooked foods are minimal if I consume high meat beforehand, suggesting little conflict. The real key issue is to get hold of high-meat from a high-quality raw source - if the raw animal food comes from a polluted bay or from a grainfed cow etc., then one should avoid aging it like the plague.
