A study suggests that if a person is deficient in vitamin D they may be at much greater risk of developing diabetes.
The scientists studied a cohort of 903 healthy adults with no indication of either pre-diabetes or diabetes during clinic visits over a two year period. They then followed the participants through 2009. Vitamin D levels in blood were measured during these visits, along with fasting plasma glucose and oral glucose tolerance.
Over the course of time, there were 47 new cases of diabetes and 337 new cases of pre-diabetes, in which blood sugar levels are higher than normal but not yet high enough to be categorized as type 2 diabetes.
For the study, the researchers identified the minimum healthy level of 25-hydroxyvitamin D in blood plasma to be 30 nanograms per millilitre. This is 10 ng/ml above the level recommended in 2010 by the Institute of Medicine. Many groups, however, have argued for higher blood serum levels of vitamin D, as much as 50 ng/ml. The matter remains a topic of debate among many academics.
The co-author of the study said persons with 25-hydroxyvitamin D levels below 30 ng/ml were considered vitamin D deficient. These persons, the researchers found, were up to five times at greater risk for developing diabetes than people with levels above 50 ng/ml.
The findings are reported in the April 19, 2018 online issue of PLOS One.
