People genetically intolerant to lactose, the main sugar found in dairy, have lower blood levels of vitamin D than the general population, new research from the University of Toronto shows. The researchers found those who had a gene associated with lactose intolerance (called LCT) consumed lower amounts of dairy products than those without that variation… Read more

Sunlight, in addition allowing us to make vitamin D, energizes T cells that play a central role in human immunity, Georgetown University Medical Center researchers have found. The findings suggest how the skin, the body’s largest organ, stays alert to the many microbes that can nest there. The study’s senior investigator, Gerard Ahern, PhD, associate… Read more
