Study Objective
To examine the association between vitamin A, E, C, and D intake (from diet and supplements) and the prevalence of respiratory complaints in UK adults.
Short Abstract
This study used data from the UK National Diet and Nutrition Survey to explore the relationship between vitamin intake and respiratory complaints. The findings indicated that higher intake of vitamins A and E from diet and supplements, and vitamin D from supplements, was associated with a lower prevalence of respiratory complaints. Vitamin C intake showed no association with respiratory outcomes.
