THURSDAY, Oct. 29, 2020 (HealthDay News) -- For U.K. adults, intake of vitamins A and E from diet and supplements and intake of vitamin D from supplements are inversely associated with respiratory complaints, according to a study published online Oct. 27 in BMJ Nutrition, Prevention & Health.

Suzana Almoosawi, Ph.D., from Imperial College London, and Luigi Palla, Ph.D., from London School of Hygiene & Tropical Medicine, examined the cross-sectional association between vitamins A, E, C, and D from diet and supplements and the prevalence of respiratory complaints among U.K. adult participants of the National Diet and Nutrition Survey Rolling Programme.

The researchers identified respiratory complaints in 33 of the 6,115 adult patients aged 19 years and older. There was a negative association noted between intake of vitamins A and E from diet and supplements and respiratory complaints after adjustment for potential confounders. An significant inverse association was seen for vitamin D intake from supplements, but not diet. There was no association observed between vitamin C and respiratory complaints.

"In conclusion, in U.K. adults, intake of vitamin A and E from diet and supplements, and vitamin D from supplements is associated with lower self-reported prevalence of respiratory complaints," the authors write. "These findings provide some basis for further research into the value of vitamin intake up and beyond recommended dietary intake."
