A study conducted by researchers at University of California San Diego School of Medicine and Seoul National University suggests that persons deficient in vitamin D may be at much greater risk of developing diabetes.
How and on whom was the study conducted:
The Researchers studied a sample size of 903 healthy adults (mean age: 74) with no indications of either pre-diabetes or diabetes during clinic visits from 1997 to 1999, and 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 milliliter. Here are 6 signs to know if you are deficient of Vitamin D.
What did they find?
The researchers Found that participants with blood levels of 25-hydroxyvitamin D that were above 30 `ng/ml had one-third of the risk of diabetes and those with levels above 50 ng/ml had one-fifth of the risk of developing diabetes, reported Sue K. Park, MD, in the Department of Preventive Medicine at Seoul National University College of Medicine in South Korea.
How to prevent the risk?
To reach the ideal 25-hydroxyvitamin D levels of 30 ng/ml, an individual requires dietary supplements of 3,000 to 5,000 international units (IU) per day, less with the addition of moderate daily sun exposure with minimal clothing (approximately 10-15 minutes per day outdoors at noon).
