Ok- I think asparagus are low in oxalates, but that's the only one. sigh.
eta: calling Tanya.... she takes a K supp, right?

A couple other things - apparently bleeding can be a side effect of Vite K deficiency (CS, maybe this is why your DD gets blood in her poops??? Basically, they "bruise" easily). And salicylate drugs can cause Vite K deficiency, so I bet food sals can too. Also requires good fat absorption in the gut, which is likely suspect for at least some of our kids. Bacterial overgrowth can also affect Vite K absorption.
ETA2: Here's the bacteria strains that produce vitamin K, at least in newborns: http://www.informaworld.com/smpp/con...8149647&db=all
(Enterobacter agglomerans, Serratia marcescens and Enterococcus faecium). CS, did any of those happen to be in your DD's stool test?
Yeah, form matters. Plant (greens) form, K1 is used primarily for clotting, which is why it's given to newborns. K2 is the form that affects calcium metabolism, and the studies were done on MK-4. Fermented foods (natto) have MK-7, which has a longer half life (a day or so instead of hours) but isn't studied like MK-4 is. MK-4 is the animal form that's in yellow butter, and also bone marrow and a few other organ meats. Your body can convert between the two somewhat, but it's limited. There's also a limit to how much K1 you can absorb (and process?) from foods, but not for K2. Either needs good fat absorption, since it's a fat soluble vitamin.
Sals act as blood thinners, I'm not sure why, maybe because they inhibit the methyl cycle and so lower homocysteine? Think aspirin...
And yeah, those K quotes sound a LOT like the vitaminK group if you want more reading or to know where the advice is coming from...
