Researchers found the yogurt drink “doogh” fortified with vitamin D significantly reduced inflammatory markers in patients with type 2 diabetes.
Tirang Neyestani, PhD, of Beheshti University of Medical Sciences in Tehran, Iran, and colleagues conducted a double-blind, randomized controlled trial over 12 weeks in 90 patients with type 2 diabetes.
Patients were randomly assigned to one of three groups, plain yogurt, yogurt plus vitamin D, or yogurt plus vitamin D and calcium.
Multiple inflammatory markers were reduced in participants who ate yogurt fortified with vitamin D, or D and calcium yogurt. The researchers also reported an increase in adiponectin, a hormone known to have anti-inflammatory properties and regulates glucose metabolism.
The authors acknowledged that the study is limited due to 75% of the patients being vitamin D deficient before supplementation began. They call for further research to investigate further potential benefits of vitamin D on inflammatory markers.
