VITAMIN D LEVELS LINKED TO INSULIN RESISTANCE

Vitamin D intake may be linked to insulin resistance. Researchers administered oral glucose tolerance tests to 126 healthy volunteers who had no obvious symptoms of glucose intolerance. Blood glucose levels declined more slowly in test subjects with low vitamin D levels. These subjects were also more likely than their peers to show signs of metabolic syndrome including obesity, hypertension and insulin resistance. The results from this study suggest that people with low vitamin D levels have a higher risk of developing insulin resistance and metabolic syndrome.
