I have often combined eating high-meat with eating raw, fresh meat and that did nothing to alter high-meat's effects. However, combining high-meat with cooked food of any kind rendered the effects of high-meat mostly null and void. In the past, I often used to eat some high-meat before going to a cooked dinner or some such, as the ingestion of high-meat helped prevent the hangover-like effect I otherwise later got from eating cooked foods, and it also helped improve my digestion of the cooked foods, no doubt due to the excess bacteria in it.
