Insufficient Vitamin D Levels Linked To Increased Risk Of Asthma In Black Children

March 22, 2010 by  

Insufficient vitamin D levels linked to increased risk of asthma in African American childrenBlack children with low blood levels of vitamin D may be at a significantly increased risk of developing asthma compared to those with sufficient levels of the nutrient, according to a new study.

Lead author Robert Freishtat, principal investigator at the Children’s Research Institute in Washington, D.C., and his colleagues took blood samples from 85 black children suffering from asthma and compared their vitamin D levels to 21 healthy black children of a similar age.

The researchers were surprised to find that approximately 86 percent of children with asthma had inadequate levels of vitamin D, while only 19 percent of healthy participants suffered from the nutrient deficiency.

“We were shocked to see that almost all of the African-American children with asthma that we tested had low vitamin D levels,” said Freishtat. “After adjusting for differences in age, weight, and the time of year of the testing, the odds of these kids with asthma being vitamin D deficient were nearly twenty times those of healthy kids.”

He added that parents should ensure that their children receive adequate amounts of the nutrient through milk consumption or vitamin supplementation.

    Insufficient Vitamin D3 blood levels in adult blacks is also the cause of increased cardiovascular disease in that segment of our population. This deficiency is traceable as the cause of increased deaths from a host of associated degenerative diseases stemming from chronic inflammation that poorly trained medical doctors (not all of them) ascribe to cholesterol abnormalities.
    Our Black brothers have been taught to think this elevated death rate proves the health system is biased against them. The truth is that their skin does not generate Vitamin D as efficiently as the skin of other races. When they are influenced to take adequate Vit. D3 supplementation the conditions disappear – same thing for deficient Caucasians, or any human.
    The bias exists in medical theories, FDA policies against natural practices (and substances) and the cultural tunnel-vision which focusses on drugs and technology as the only way to make the body work properly. How silly!
    If you have a motor constructed to run on coal and water, but you try to force it to work on sheets and wind you’re going to have problems. It will be an invalid until you fire it with what it needs. Our bodies are no different. Medical science may try to say, “Put this poison in your body. It should make you work better.” But if the Manufacturer’s specs and instruction sheet says something different… well, there isn’t even any reason for me to say, “Good luck with that.” Let the buyer beware.

      If you are not already aware D3 is preferable (by far!) as it is the natural precursor generated in our skin via UVB (sunlight) radiation.

      D3 is twice as available for your body vs. D2. D2 (ergocalciferol) is an artificial form of D made from irradiating plant matter with UVB. Incredibly, D2 is almost always what is prescribed by doctors to correct vitamin D deficiency. In the prescription form it is much, much, more expensive, not as bioactive, and in every way inferior to any D3 bought over the counter.

      Should your doctor or any other medical type dispute the superior nature of D3 go to this web link about the efficacy of D3 vs. D2, print out the info, hand it to your doctor, and fire him/her. What your doctor does not know about vitamin D may kill you.

      In general doctors know almost nothing about vitamin D. EVERYTHING they learned about it in 2 hours of lectures in medical school is COMPLETELY WRONG. You may well have to educate them about it’s beyond vital importance.

      To find out the facts: Vitamin D Council and Grassroots Health and Vitamin D3 World are excellent places to start your adventure.

      In the end, NOTHING is as important as raising serum blood levels to at least 50 ng/ml of activated vitamin D (25 OH D).

    In the last twelve months, multiple studies have shown a connection between Vitamin D and asthma. Initially, studies demonstrated that Vitamin D deficiency may be a significant causative factor in the development of the condition. More recently, clinical trials have shown that those with higher Vitamin D levels show an improved patients response to standard asthma treatments and Vitamin D supplements significantly reduce the number and severity of asthmatic attacks in children. You can see a summary of this information at Most of us have been shown to have insufficient levels of vitamin D and the American Society of Pediatricians recently doubled the daily recommended intake

    The evidence for the benefits from vitamin D is nothing short of astonishing and keeps coming in. From helping to ward off cancer to possibly curing the common cold to preventing influenza and other positive findings, the sunshine vitamin has a bright future indeed. When you throw in that because of poor diet and a modern lifestyle which decreases exposure to sunshine average vitamin D levels are likely lower than in the past, it is not a stretch to speculate that very many of the diseases of modern society may be directly related to or partially influenced by a deficiency of this lion of a vitamin. There is a little bit of an intro to the topic here,
    and here
    if anyone is interested. Also the web abounds with resources on the topic. Oh yes don’t forget help with obesity, asthma and bone health

    So get out and enjoy the sun on your face this Spring. Won’t even cost your a dime.
