High Vitamin D Levels Associated with Greater Insulin Sensitivity
Poor insulin sensitivity results in sustained elevation of insulin due to an inability to force glucose into muscle tissues, and is a risk factor for diabetes. According to a new study, vitamin D may help promote greater insulin sensitivity.
680 Brazilian women aged 35 to 74 years participated in the study. The researchers took fasting blood samples to measure vitamin D and glucose levels. The women were also interviewed to determine if they took vitamin D supplements, and the amount of exposure they got to the sun. 3.5% of the participants reported using vitamin D supplements.
When the researchers compared vitamin D levels and glucose levels, they found that vitamin D levels greater than 30 ng/ml were positively associated with low glucose levels. Habitual exposure to the sun was also positively associated with low glucose levels. Vitamin D deficiencies were found to be positively associated with high glucose levels.
The study was conducted by researchers from the University of Sao Paolo School of Public Health. It was published January 18, 2019 in the journalMenopause.
