Below are two items I just gleaned from my Eurekalert! RSS feed, and they seem to fit together nicely:
1) One in seven US teens is vitamin D deficient
One in seven American adolescents is vitamin D deficient, according to a new study by researchers in the Department of Public Health at Weill Cornell Medical College. The findings are published in the March issue of the journal Pediatrics and were presented at the Pediatric Academic Societies’ Annual Meeting in May 2008.
2) Not enough vitamin D in the diet could mean too much fat on adolescents
Too little vitamin D could be bad for more than your bones; it may also lead to fatter adolescents, researchers say.
A Medical College of Georgia study of more than 650 teens age 14-19 has found that those who reported higher vitamin D intakes had lower overall body fat and lower amounts of the fat in the abdomen, a type of fat known as visceral fat, which has been associated with health risks such as heart disease, stroke, diabetes and hypertension.
The group with the lowest vitamin D intake, black females, had higher percentages of both body fat and visceral fat, while black males had the lowest percentages of body and visceral fat, even though their vitamin D intake was below the recommended levels. Only one group – white males – was getting the recommended minimum intake of vitamin D.
“This study was a cross-section so, while it cannot prove that higher intake of vitamin D caused the lower body fat, we know there is a relationship that needs to be explored further,” says Dr. Yanbin Dong, a molecular geneticist and cardiologist at the MCG Gerogia Prevention Institute.
