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.

It is from 1940. So they probably changed the processing to make it more edible for human consumption..
Well the process of pasteurization is pretty simple. Generally heat to 155F and all the microbes beneficial or not die off. It’s an easy way to make food safe, but dead and we didn’t evolve eating food without microbes.
