Mütter, die in ihrer Kindheit Widrigkeiten erlebt haben, weisen in ihrer Muttermilch unterschiedliche Muster von microRNAs und Fettsäuren auf. Diese molekularen Unterschiede hängen mit dem Temperament ihrer Säuglinge zusammen und liefern Hinweise auf einen möglichen biologischen Weg intergenerationeller Auswirkungen von frühem Lebensstress

I wonder what the purpose is, since I imagine cave women didn’t exactly lead stress free lives. Hell, while it’s relative, the things we consider “childhood adversity” I feel have been much more common and much worse going back in time.
If this is true and this transfers to cow milk, formula must be very bad since we have horrible factory farming.
>For example, higher expression of miR-142-5p in breast milk was associated with infants showing more high-intensity pleasure at 12 months. At the same time, lower expression of this microRNA was linked to infants showing more distress when faced with limitations.
I would think that lower distress when faced with limitations could be adaptive? Especially if the distress would otherwise impair function? I looked into the findings a bit more and they’re interesting, and don’t give the impression these epigenetic factors are all negative.
