Vitamin D deficiency is widespread. In fact, there have been so many studies linking many of today’s disease epidemics to inadequate blood levels of vitamin D that to deny a connection is utter foolishness. But a committee from the Institute of Medicine (IOM) has made a strange — and false — announcement on behalf of the U.S. and Canadian governments that North Americans already get plenty of vitamin D and do not need to supplement with the vitamin to maintain good health.
The “Food and Nutrition Board” committee that compiled the report basically came to the conclusion that current recommended daily intake (RDI) levels for vitamin D (which are typically no more than 400 international units (IU) of the vitamin a day) are good enough. The committee also had the audacity to suggest that the only benefit to be derived from vitamin D is to maintain healthy bones when consumed along withcalcium.
According to the IOMwebsite, the group is an “independent, nonprofit organization that works outside ofgovernmentto provide unbiased and authoritative advice to decision makers and the public.” But a simple glance at the report announcement released today reveals that “the United States and Canadian governments asked the IOM” to conduct the report. Not so unbiased after all, is it?
One has to wonder what data the committee used to come to its conclusion because a plethora of studies have shown thatvitamin D deficiency— and by deficiency, this means levels that meet current RDI guidelines, but that are woefully inadequate at preventing serious illness — is linked to heartdisease, hypertension, autoimmune diseases, stroke, diabetes, depression, chronic pain, arthritis, osteoporosis, birth defects, muscle problems, and cancer, among many other things.
The group even went so far as to warn people not to supplement with vitamin D because it insists that doing so “may be harmful”. But again, numerousstudieshave shown that intake levels far above current RDI guidelines are not only safe, but also highly beneficial in warding off many of the serious diseases that people face in today’s world.

Vitamin D controls genetic expression for health, disease

Vitamin D is especially active in areas of the human genome related to autoimmune diseases, providing yet more evidence that the vitamin plays a critical role in regulating the immune system and protecting against certain diseases.
In a study published in the journalGenome Research, researchers from Oxford University mapped the human genome looking for clusters of vitamin D receptors — sites where the vitamin can bind to DNA, changing the expression of a gene. They found that these receptors were especially common in regions that have previously been linked to common autoimmune diseases, includingType 1 diabetes, multiple sclerosis and Crohn’s disease.Vitamin Dreceptors were also common in regions linked to colorectalcancerand leukemia.
The study shows how serious the effects of vitamin D deficiency can be, the researchers noted.
Scientists have long known that vitamin D plays an essential role in maintaining healthy teeth and bones, but only recently has the vitamin’s role in immune regulation started to become clear.
“Thebenefitsof vitamin D include a reduction in the risk of colon polyps and prostate cancer, less coronary arterydisease, and a decreased chance of developing type 1diabetes, plus increased musclestrengthand coordination, along with higherbonestrength,” writes Phyllis A. Balch in her bookPrescription for Nutritional Healing, 4th Edition.
The best source of vitamin D is exposure to sunlight. In only a fraction of the time it takes to burn, thebodycan produce up to 10,000 IU of the vitamin — as little as 15 minutes per day for light-skinned people and as much as three times that for people with much darker skin.
Sunscreen blocks the ultraviolet radiation that the body needs to synthesize vitamin D.
