StudyShows Vitamin D May Help Prevent Respiratory Tract Infections
Vitamin D may reduce the incidence and severity of influenza and other infections of the upper respiratory tract, new research indicates.
Simple steps such as eating foods rich with vitamin D and getting more sunshine may help to reduce your chances of contracting flu and other similar illnesses, shows a study by scientists at Yale University School of Medicine and Greenwich Hospital in Connecticut.
“People in the South and West get more sun than in the North, which is good for them, because you get vitamin D from the sun,” study researcher James R. Sabetta, MD, of the Yale University School of Medicine and Greenwich Hospital, Conn., tells WebMD. “It’s not a panacea, but it helps.”
Sabetta and his team of colleagues followed 198 healthy adults during the fall and winter of 2009-2010 to see if declining levels of vitamin D in the fall and winter could be a factor in the seasonal increased prevalence of respiratory viral infections, such as flu.
