Teens in Danger from Epidemic of Low Vitamin D

[Guest guest]

(NaturalNews) America's teens too often are inside glued to their computers and

video games instead of playing and even working outdoors like previous

generations did. What's more, too many youngsters eat junk food instead of

healthy whole foods. So there's plenty of reason to be concerned about a

deficiency of vitamin D, also known as the " sunshine vitamin " , in this segment

of the population. And, in fact, two just released studies show American youth

are facing potentially severe health consequences from a lack of this important

vitamin.

This week at the American Heart Association's 49th Annual Conference on

Cardiovascular Disease Epidemiology and Prevention, P. Reis, Ph.D., and

his team of researchers at s Hopkins Bloomberg School of Public Health in

Baltimore announced their findings of a study of 3,577 adolescents, 12 to 19

years old (51 percent boys), who participated in the nationally representative

National Health and Nutrition Examination Survey (NHANES) conducted from 2001.

The scientists used a biomarker in the research subjects' blood to measure

vitamin D obtained from food, vitamin supplements and exposure to sunlight.

" We showed strong associations between low levels of vitamin D and higher risk

of high blood pressure, hyperglycemia and metabolic syndrome among adolescents,

confirming the results of studies among adults, " Dr. Reis said in a statement to

the media. Low levels of vitamin D could also help explain why American teens

are becoming fatter. A lack of the vitamin is strongly associated with being

overweight and obesity centered around the abdomen, Reis noted.

Specifically, the youngsters with the lowest levels of vitamin D were 2.36 times

more likely to have hypertension, 2.54 times more likely to have high blood

sugar and about 4 times more likely to have metabolic syndrome -- a group of

cardiovascular disease and diabetes risk factors that includes an increased

waist circumference, high blood pressure, elevated triglycerides, low levels of

high-density lipoprotein (HDL or " good " ) cholesterol and high fasting glucose

levels.

But how wide-spread is the lack of vitamin D in teens? Another study by

researchers in the Department of Public Health at Weill Cornell Medical College

published in the March issue of the journal Pediatrics gives the answer -- about

one in 7. Girls were found to have twice the risk of vitamin D deficiency than

boys. What's more, overweight teens had nearly double the risk of being vitamin

D deficit than their counterparts of normal weight.

The study used new criteria of vitamin D deficiency recommended by a group of

scientists who worked together at the 13th Workshop Consensus for Vitamin D

Nutritional Guidelines in 2007 and concluded the minimum acceptable serum

vitamin D level should be raised from 11 nanograms per milliliter (ng/mL) to at

least 20 ng/mL. Using this definition, the study found more than half of

African-American teens are vitamin D deficient.

" These are alarming findings. We need to do a better job of educating the public

on the importance of vitamin D, and the best ways to get it. To meet minimum

nutritional requirements teens would need to consume at least four glasses of

fortified milk daily or its dietary equivalent. Other foods rich in vitamin D

include salmon, tuna, eggs and fortified cereals. A vitamin supplement

containing 400 IU of vitamin D is another alternative, " said researcher Dr.

Sandy Saintonge, assistant professor of clinical pediatrics and assistant

professor of clinical public health at Weill Cornell Medical College, in a

statement to the media.

Getting enough sunshine is also a healthy way to boost levels of the vitamin.

According to the National Institutes of Health (NIH) web site, approximately 5

to 30 minutes of sun exposure between 10 AM and 3 PM at least twice a week to

the face, arms, legs, or back without sunscreen usually leads to sufficient

vitamin D synthesis.
