Considering that vitamin D wasn't discovered until the
early 20th century, and that vitamin D levels in dairy
products decrease with oxidation, I'd say that this
one was total bunk. Vitamin D is produced in animals
and plants through exposure to UV radiation - but
that's in a *living* animal or plant.
Tertiary source that doesn't provide (or link to)
primary or even secondary sources. Given some of the
broad statemens and the misinformation/misleading info
on butter above, I wouldn't take anything from this
site as accurate unless it could be backed up with
other, better documented sources.
