Probably an extreme view, I’d like to see the research papers, but generally I think pasteurization has had a deleterious effect on the health and diversity of the cultures in our micro biome, and has had a corresponding negative affect on our wellness, perhaps most profoundly our mental health. Too clean is not healthy, we pasteurize to protect the weak. Expending energy on, or compromising to accommodate the unfit segments is a recipe for the downfall of our species.
