- Here is a reference to a recent and interesting paper published
- by Professor J. Moon et al. on "vitamin" D or calciferol..
-
- Moon, J. et al. 1992. "Etiology of Atherosclerosis and
- Osteoporosis: Are Imbalances in the Calciferol
- Endocrine System Implicated?" JOURNAL OF THE
- AMERICAN COLLEGE OF NUTRITION, 11(5):567-583.
-
- Here are some of the concluding remarks from this scholarly paper:
-
- In 1983 Fraser stated,
- The oral route as a means of supplying vitamin D
- is ineffective, unnatural, and potentially
- dangerous. Yet, to achieve adequate exposure to
- the sun of whole populations such as those in
- large cities may well prove impractical. Human
- ingenuity might therefore have to devise another
- way of providing vitamin D -- one which takes into
- account the natural physiology of its formation
- and processing in the human body.
- Data accumulated since that time add support to this
- observation. Thus, the 10 edition of the US RDAs
- concludes:
- Since the toxic level of vitamin D may in some
- cases be only 5 times the RDA, and there is
- evidence that sunlight-stimulated production of the
- vitamin active throughout the warm months, dietary
- supplements may be detrimental for the normal
- child or adult who drinks at least two glasses of
- vitamin D-fortified milk per day.
-
- In as much as vitamin D is not an essential dietary
- component fro the vast majority of people, and
- relatively small excesses may be toxic in the long
- term, we concur with the recommendation of Peng &
- Taylor [ ] that "reclassification as a potent,
- carefully controlled hormone should be seriously
- considered." We similarly agree with recommendation of
- Holmes and Kummerow [ ]:
- "that fortification of foods with vitamin D should
- be curtailed, preferably abolished, that excessive
- fortification of animal foods be reduced to the
- level required, and that the use of dietary
- supplements be restricted."
- We further recommend that, to avoid confusion that might
- lead to excessive self-administration, the more correct
- hormone name, "calciferol", rather than the common
- name, "vitamin D,", be used for labelling purposes.
- Calciferol should be available, on the advice of a
- physician, for those infants or others at risk of a
- deficiency, but should not be administered to the
- general, calciferol-sufficient population.
-
- [Note: for brevity, I've omitted the references Moon et
- al. cite in the above passage]
-
- Lest we again see some flames concerning this simple posting
- of some conclusions from a published scientific paper,
- permit me to state what should not need stating.
-
- Again, please don't EVER take my, or anyone else's, word for it nor
- should one rest content with just a few citations. Go read for
- yourself what is an interesting and possibly important paper.
-
- I think we can all agree that we must always be wary and
- leery of those PSEUDO-EXPERTS who would merely make his or
- her assertions `ex-cathedra', who would resort to a
- patronizing tone or even insults, and ultimately would
- disrespect your independent intelligence. The truly
- informed have no need to belittle others and are quite
- willing to patiently explain and provide substantiation or
- references for their crucial points.
-
- What needs to be encouraged is our independent understanding
- and judgement of things even as technical as nutrition.
- After all, we all must bear some responsibly for our own
- health care. But more important, we need to read for ourselves
- some of the literature.
-
- Have a Academic New Year Everyone :-)
