Wife is pregnant and while reading a couple midwife/ gyneocology literature I came about the fact that all infants are born with something around 1/5 of the vitamin K amount when adjusted for size and compared to adults and older children.
This got me curious. Why would this deficiency exist in the first place? Surely it either is due to some kind of evolutionary beneficial system which we yet haven't found or due to the fact that modern humans barely consume any vitamin K (especially not K2, which is mainly found in fermented foods). But than again, the placenta barely lets any vitamin K through, so it does sound as if this might be "by design".
The available data also speaks about the fact that breastmilk contains nearly no vitamin K, but looking through the studies it looks like that might be mainly due to the maternal look intake in modern humans:
