Hormesis is a pretty interesting thing (thanks, as TIL). Just a thought, the tiny amount of ethanol in fermented dairy products like cultured buttermilk, yogurt, and kefir, could maybe play a tiny factor in some of its health benefits? The logic here is that for a micronutrient such as Vitamin A that all it takes is 1/1000th of a gram on a daily basis for health benefits (the same goes for many other vitamins' RDA for humans). As an aside, there is an interesting part of the ethanol section in the Wikipedia entry [0] on hormesis: > In 2012, researchers at UCLA found that tiny amounts (1 mM, or 0.005%) of ethanol doubled the lifespan of Caenorhabditis elegans, a roundworm frequently used in biological studies, that were starved of other nutrients. Higher doses of 0.4% provided no longevity benefit.[22] However, worms exposed to 0.005% did not develop normally (their development was arrested). The authors argue that the worms were using ethanol as an alternative energy source in the absence of other nutrition, or had initiated a stress response. They did not test the effect of ethanol on worms fed a normal diet. [0] https://en.wikipedia.org/wiki/Hormesis https://en.wikipedia.org/wiki/Hormesis
