The latest news on vitamin D comes from Iran, where a study found that drinking yogurt containing extra vitamin D may help individuals with diabetes regulate their blood sugar. Researchers divided 90 adult diabetics into three groups. Each group received yogurt drinks twice a day, one group's drink was plain yogurt, one contained extra vitamin D and one had extra vitamin D and calcium. After 12 weeks the investigators found a "relatively remarkable improvement" in blood sugar levels in the groups that were given the extra vitamin D. The study was published online on Feb. 2, 2011, by the American Journal of Clinical Nutrition. In other news about "D" researchers from the Albert Einstein College of Medicine in New York checked blood levels of vitamin D in samples collected (in 2005-2006) from more than 3,100 children and teens and 3,400 adults nationwide. They found that low vitamin D levels in the children and teens were associated with an increased risk of developing allergies. The low levels of "D" among the kids were correlated with a sensitivity to 11 of 17 allergens tested including ragweed and food allergens. No such association was seen in the adults.
