Vitamin D deficiency in children increases diabetes risk

When scientists in the US compared the prevalence of vitamin D deficiency in non-overweight children with children who were overweight, they made some shocking discoveries.

More than 400 obese children aged 6-16 were compared with 87 non-overweight children.

They found that Vitamin D deficiency was common among both groups, but especially so in the overweight group.

More than 9 out of 10 overweight children had vitamin D levels below the optimal 75nmol/litre, and 50% were below 50nmol/litre.

Among the non-overweight children, almost 7 out of 10 had vitamin D levels below the optimal, and 2 out of 10 were below the 50nmol/litre mark.

The researchers found that the blood test results showed that low vitamin D levels were significantly associated with insulin resistance and high blood sugar levels, which are risk factors for type II diabetes.
