A new study by Dr. Harri Hemila from the Univeristy of Helsinki shows that Vitamin E may prevent pneumonia in non-smoking elderly men. According to a paper published in Clinical Interventions in Aging, administration of 50mg per day of Vitamin E decreased the risk of pneumonia in elderly male smokers by 72% after they quit smoking.
The study proved that the age when the participant had started to smoke significantly modified the effect of Vitamin E on pneumonia. Vitamin E decreased the risk of pneumonia by 35% in 7,469 participants who started smoking at a later age, whereas the vitamin had no apparent effect on pneumonia for those who had started smoking at a younger age.
A third of the 7,469 participants has quit smoking for a period of time and 27 of them got pneumonia. These 27 cases can be used to estimate the effect that Vitamin E has on currently non-smoking males. The incidence of pneumonia was 72% lower in the participants who had quit smoking.
The vitamin did not show significant results on participants who smoking heavily or did not exercise.
