For quite some time now I like to buy a "Field Greens" salad mix at my 
local grocery store.  It contains a bunch of baby greens and I've been 
very curious as to why they would use "baby" greens in the first place, 
how paleo they are, and if there is any disadvantage to eating baby 
greens versus normal ones.  It has baby lettuces and baby greens (tat 
soi, spinach, chard, arugula).  Very convenient for me but I'm wondering 
if anyone has any thoughts on this as I've never come across any mention 
of it on the list or elsewhere.
