mycket djurprodukter kan leda till minskad Vitamin D-produktion. Vi vet
också att djurprodukter orsakar cancer och de auto-immuna sjukdomar som
man har funnit är korrelerade med Vitamin D-brist.
Hollick agrees with the common medical assessment that somewhere
between 30 and 80% of the American population is Vitamin D-deficient.
He also agrees with the research showing that people with lower Vitamin D
levels are at higher risk of developing many conditions, including
cancer. However, he does not recommend the use of supplements, fortified
foods and oily fish to compensate for this deficiency. In fact, Dr.
Hollick states that for every 100IU of Vitamin D you ingest orally, you
raise blood levels of 25 hydroxyvitamin D by only 1 nannogram per
Hollick instead recommends getting sun exposure as a way of increasing
blood levels of vitamin D. Just 10-15 minutes in the sun is the
equivalent of taking between 15,000 and 20,000 IU's of Vitamin D, but
without the potential for toxicity that is becoming more common as
people take larger doses of it orally.
Hollick criticizes the use of sunscreen in order to avoid all sun
exposure. A sunscreen with SPF of 8 reduces the ability of the skin to
make Vitamin D by 92.5%. Sunscreen with SPF 15 reduces it by 99%.
the winter months, the inactive, storage form of Vitamin D is drawn
upon for use when sun exposure is limited or non-existent. Dr. Hollick
does not discuss this in his interview, but the conversion process can
be hampered by the consumption of a diet rich in animal foods, fat and
refined foods, so adequate Vitamin D levels are dependent on both diet
and sun exposure."

both cases, consuming extra amounts of vitamins A and D runs the risk
of violating the natural order of things by exceeding the upper limits
of circulation desired by the body. Is it any wonder, then, that these
are the two vitamins with the greatest number of reports of toxicity?
Did you know, for example, that vitamin A at higher levels of intake,
actually can increase, not decrease, cancer risk? Also, did you know
that these are the only two vitamins only found in flesh foods (a
different kind of vitamin D may be present in some plants)?
Historically, it now is clear that they initially were labeled as
vitamins at a time when consumption of generous amounts of animal foods
was considered advisable.
do not mean to say that consuming vitamins A and D, as supplements or
as added to foods, is never useful, but I do mean to say that the
benefits to be derived, if any, are observed, in theory, only when
Ã›-carotene intake (from colored plant matter) and sunshine exposure are
inadequate. Both of these presumed 'vitamins' are downstream from their
major sources and it is these sources which we need to emphasize."
Hollick is considerably more conservative than I am - I generally
recommend doing away with fortified foods and supplements, including
Vitamin D since the body in its infinite wisdom can achieve and maintain
optimal health naturally through dietary excellence and optimal habits.
