VITAMIN D STOPS THE FLU

Vitamin D May Cut Risk of Flu
By Bill Hendrick

June 17, 2010 - 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. The study shows people who maintain vitamin D blood levels of 38 nanograms per milliliter or more are less likely to get viral infections such as flu than people with less in their blood.

Of 18 people who maintained that level during the study period, only three developed viral infections. But of the 180 other participants with less vitamin D in their blood, 81(45%), did get sick with viral infections. And those with higher levels of vitamin D also experienced a marked reduction in the number of days they were ill, Sabetta tells WebMD.

In addition to getting more sun and consuming milk and foods with vitamin D, he recommends supplements, especially for people in areas with less sunlight and for those who spend daylight hours in darker, indoor environments.
