"Primitive diets, whether they included primarily meats (land or sea) or not were almost always alkalizing as the growing conditions of the wild plants were mineral dense"
It appears that you've reached a conclusion that if wild plants are grown in mmineral dense environments that they will be more mineral dense than modern plants, and that "mineral dense" are necessarily "alkalizing". I'm not clear on what constitutes "mineral dense", versus, for example, "mineral sparse" wild plants, or plants having a mineral content that resides between dense and sparse. If a non-mineral dense wild plant were considered, would this mean that it is non-alkalizing ?
Do wild plants exist which are mineral dense that are non-alkalizing ?
The meaning of this is indefinite, to me, in that alkaline substances are regarded as those which cause an increase in solution pH upon being dissolved in a solvent, which is typically water. Typically, alkalizing substances are those which contain hydroxide anions, yet plants are generally devoid of hydroxide ions.
