A new study published in Archives of Internal Medicine reports that "higher levels of vitamin D may protect against the common flu and cold".
This study found that among 19,000 adults and adolescents, people who had the lowest blood levels of vitamin D were 40% more likely to have recently experienced a cold or flu. The authors of this study also noted that low levels of vitamin D were linked to even higher risk of respiratory complications in those who suffer from chronic respiratory disorders (asthma, emphysema, and chronic obstructive pulmonary disease).

Although further studies are needed to confirm this observation, it certainly contributes to the list of potential health benefits linked to this immune fighting vitamin!
Note to my friend with pneumonia: Another reason to take those vitamin D pills !!
