Primitive forms of innoculation, antiseptic, and pasteurizing go back centuries if not millennia. The very idea of the small pox vaccine came out of the recognition that cow pox mitigated the risk of contagion. Milk maids were (unwittingly) vaccinating themselves for some time.
And pasteurization is just cooking your food. Hell, the whole reason primitive people started baking bread, roasting meat, and brewing beer came down to the benefits of sterilization.
These aren’t even new ideas, per say. They’re advances in technique, understanding of consequence, and means of distribution.

It’s to start the break down of food. We evolved to outsource our digestion to cooking.
Brewing beer is entirely different though.

That too. But killing parasites in meat and fish is another big benefit.
We evolved to outsource our digestion to cooking.
To a degree. But we also just died more often to infection and disease. Cooking reduced mortality rates, which spurred a larger population, whose members transmitted the knowledge of how and what to cook before eating.
I mean our evolution really kicked off so to speak from outsourcing our digestion. That meant more calories could go to the brain. That’s the aspect I’m focused on.
