People with vitamin D deficiency appear to have a much higher risk of having pre-diabetes and type 2 diabetes than those with normal levels of vitamin D, according to a new study by the University of California San Diego School of Medicine and Seoul National University in South Korea.
The study was conducted in 903 healthy adults, mean age 74 without signs of pre-diabetes or diabetes, from 1997 to 1999, who were followed up by 2009. During the study, researchers measured plasma levels of vitamin D in blood and glucose as well as glucose tolerance. They defined vitamin levels as normal at 30 ng / mL.
According to the researchers, participants with vitamin D deficiency were five times more likely to develop type 2 diabetes than those who had levels above 50 ng / mL. The findings of epidemiological research were published in the journal PLOS One.
