A new study has examined that people who have low levels of vitamin D are more likely to have diabetes, regardless of how much they weigh.
The study conducted by the Endocrine Society found that people who have low levels of vitamin D are more likely to be obese and they also are more likely to have Type 2 diabetes, prediabetes and metabolic syndrome than people with normal vitamin D levels.
Vitamin D helps the body absorb calcium and maintain bone and muscle health. The skin naturally produces this vitamin after exposure to sunlight. People also absorb smaller amounts of the vitamin through foods, such as milk fortified with vitamin D.
One of the study’s authors, Mercedes Clemente-Postigo, said that the major strength of this study was that it compares vitamin D levels in people at a wide range of weights while taking whether they had diabetes into account.
The cross-sectional study compared vitamin D biomarkers in 118 participants at the university hospital Virgen de la Victoria in Malaga as well as 30 participants from the Hospital Universitari Dr. Josep Trueta in Girona, Spain. All participants were classified by their body-mass index (BMI) as well as whether they had diabetes, prediabetes or no glycemic disorders.
The analysis found that obese subjects who did not have glucose metabolism disorders had higher levels of vitamin D than diabetic subjects. Likewise, lean subjects with diabetes or another glucose metabolism disorder were more likely to have low levels of vitamin D. Vitamin D levels were directly correlated with glucose levels, but not with BMI.
Manuel Macias-Gonzalez, PhD, said that the study suggests that vitamin D deficiency and obesity interact synergistically to heighten the risk of diabetes and other metabolic disorders. The average person may be able to reduce their risk by maintaining a healthy diet and getting enough outdoor activity.
The study is published in the Endocrine Society’s Journal of Clinical Endocrinology and Metabolism.
