Lack of vitamin D boosts heart risk in teens

Teenagers lacking vitamin D may face a higher risk for heart disease. Researchers from Johns Hopkins School of Public Health tested the blood of 3,500 teens. Those with the lowest levels of vitamin D were more than twice as likely to have high blood pressure or high blood sugar. They were also 4 times more likely to have a metabolic disorder that raises the risk for heart disease.

Another recent study also suggests vitamin D is rising among American adolescents. That may be due to poorer diets and less time spent outside.
