Youth and Sunshine does not protect us from Vitamin D deficiency


The May issue of Diabetes Care  has a couple of articles about Vitamin D that I found interesting .I will review these articles with you over the next few days.

Circulating 25-hydroxyvitamin D concentration are correlated with increased cardiometabolic risk
Among Americam Black and white aAdolescents Living in a year- round sunny Climate.

Summary
25 hydroxyvitamin D levels were measured in 701 girls and boys ( 14 to 18 ) in and around Augusta Ga.. They found that low levels of 25 hydroxyvitamin D levels were associated with increased cardiovascular risk factors such as inflammation, insulin resistance , increased blood pressure and abnormal lipid profiles.

 Take home message 
                 Youth and sunshine does not protect us from Vitamin D deficiency.

Something to think about . Our fat cells are very busy.
Adipose tissue is recoconized to function as a storage depot for vitamin D and also functions as an endocrine tissue producing cytokines ( leptin, adiponectin , resistin ) and inflammatory markers
 ( hsCRP , fibrinogen , ICAM, and TNF-a )

This article is full of interesting  Vitamin D associations with Diabetes , Blood pressure and lipids.
I will take up each association separately  over the next few days. 

Tomorrow glucose and insulin resistance.

Have Fun , Be Smart and get a little more sun
