No. But there probably is a bit of truth to it. I believe spinach
contains oxalates, which inhibit (not not totally prevent) the
absorption of calcium and... iron? OTOH, cooking will destroy some (but
not all) of the vitamins.


Beware you kidney stone formers! If yours are calcium oxalate stones, as
are mine, a few gulps of milk or a tums may tend to counteract the
oxalate content of spinach (And other greens containing oxalates).
Theory is that calcium + oxalates forms calcium oxalate in the bowels
where the "stuff" is excreted, rather in the bladder/kidneys.
