People with type 2 diabetes who consume vitamin D-fortified doogh (Persian yogurt drink) daily are at reduced risk of heart disease, according to a recent study.
Inflammation is known to have a central role in the development of type 2 diabetes and its further complications like coronary heart disease and stroke. Vitamin D carries benefits for skeletal health but evidence of an anti-inflammatory effect from clinical studies in humans remains scarce.
"Our previous research showed that improvement of vitamin D status by regular daily intake of a fortified yogurt drink resulted in lowered blood glucose levels in diabetic patients," said Tirang Neyestani, PhD, of Shahid Beheshti University of Medical Sciences in Tehran, Iran and lead author of the study. "The current study found that consuming a vitamin D-fortified yogurt drink also decreased serum substances like highly sensitive C-reactive protein (hsCRP) which are known to have an inflammatory role."
"Our study showed for the first time that adiponectin, a substance secreted by fat tissue that has an anti-inflammatory effect, increased when calcium and vitamin D-fortified doogh was consumed," said Neyestani. "Our findings may offer interesting therapeutic options for diabetic patients."
Other researchers working on the study include: Bahareh Nikooyeh, Hamid Alavi-Majd, Nastaran, Shariatzadeh, Ali Kalayi, Nima Tayebinejad, Soudabeh Heravifard, Shabnam Salekzamani and Malihe Zahedirad, all with Shahid Beheshti University of Medical Sciences.
