Black Teenagers May Improve Arterial Stiffness With Vitamin D Supplements

August 6, 2010 by  

African American Teenagers May Improve Arterial Stiffness With Vitamin D SupplementsBlack teenagers have an increased risk of experiencing arterial stiffness, a serious condition that often predicts heart disease and stroke. However, results of a new Medical College of Georgia study suggest that these individuals can reduce their risk of developing the condition by regularly taking vitamin D supplements.

Lead investigator Yanbin Dong and his colleagues recruited 44 African American teenagers and tested their vitamin D levels, finding that 95 percent of the group had a significant nutrient deficiency. The researchers then measured each participant’s arterial stiffness using pulse wave velocity.

After going through the tests, the teenagers were randomly assigned to receive either the recommended 400 IU of vitamin D each day or 2,000 IU of the nutrient.

At the point of follow-up, the participants who received the higher dose of the nutrient became vitamin D sufficient and showed signs of improving their arterial system and their cardiovascular function. In contrast, those who took 400 IU of vitamin D remained deficient and received very few benefits from the supplements.

"Our study is the first clinical trial of vitamin D intervention to use 2,000 IU in black subjects and to include cardiovascular risk factors as outcomes in youth," said Dong. "Our study indicates that the current recommendations for vitamin D intake in black teenagers may need to be revised upward."

    THIS…. is not surprising. And, I appreciate the Lab Test’s driving impetus for doing it to begin with.

    However, when it comes to vitamin D deficiencies … I doubt skin color should even be a part of the discussion… seriously.

    The bottom line, when it comes to health, is that all of us are human and any one of us having a vitamin/mineral deficiency – will have very, very similar results.

    I call this … just another case of the proof that benefits OUR side of the Big Pharma (argument?) debate.. Big Pharma says they know what’s best, and we should blindly show allegiance…

    I say: Blow it out your backsides…. FOOD, INC.

    Because America is looking down the barrel of Herr Obummer’s healthcare SCAM, you’d think health-related topics would garner more attention. In the event that someone decides he or she needs to do some research on Vitamin D supplements and supplement experts, please look up an MD named Dr. Michael F Holick.
    You might expand your knowledge, and you might wonder why so many American MDs hesitate to make supplements a part of their ‘expertise.’
    Knowledge will help you get and stay healthy. Relying on an ‘expert’ who worships the AMA and ignores new scientific research can be very bad for your health AND your wallet.
