Vitamin D and Diabetes in Children
To be published in the January 2012 edition of the Journal of Clinical Endocrinology & Metabolism, the study found that obese children with lower levels of vitamin D had higher degrees of insulin resistance, researchers said.
Though they stopped short of concluding that vitamin D deficiency causes abnormal glucose metabolism, researchers from the University of Texas said their study suggests that low vitamin D levels may play a role in the development of type 2 diabetes.
In the study, scientists measured vitamin D levels, blood sugar levels, serum insulin, BMI and blood pressure in 411 obese children and 87 non-overweight kids.
Participants were asked to provide their dietary information like soda, juice and milk consumption, average fruit and vegetable intake and breakfast-eating habits.
What emerged were clear associations between lower vitamin D levels in obese children who had poor dietary habits like skipping breakfast, and increased consumption of soda and juice, researchers said.
Meanwhile, a study published out of the University of Missouri-Columbia found that obese teenagers need significantly more vitamin D than their leaner counterparts -- seven times more than the current daily recommended intake of 600 international units (IU). That is because obese adolescents absorb vitamin D in their fat stores and are about half as efficient as their leaner counterparts at metabolizing their benefits, researchers said.
Their study called for obese adolescents to up their vitamin D intake to 4,000 IUs.
While the body is able to store vitamin D from the sunny summer months, other foods sources include cheese, mackerel, sardines, salmon and fish liver oil.
