Amid the Covid-19 pandemic, researchers, including one of Indian-origin, have found that high intake of vitamins A, E, and D may be linked to fewer respiratory complaints in adults.

Nutrition has a key role in cutting the risk of several infections, although exactly how it boosts immunity is complex and not fully understood, the study, published in the journal the BMJ Nutrition, Prevention & Health, reported.

The researchers drew on information provided by 6115 adult participants who had completed three or more days of diet diaries.

Respiratory complaints were reported by the participants and had not been diagnosed by a clinician. They were broadly defined, and included both infectious and non-infectious conditions, such as colds, chronic obstructive pulmonary disease, and asthma.

In all, there were 33 cases of respiratory complaints. These respondents were generally older and less likely to say they regularly took vitamins A, E, C or D supplements.

Vitamin A and E intake from both diet and supplements was associated with a lower prevalence of respiratory complaints in UK adults. And vitamin D intake from supplements, but not from diet, was associated with fewer respiratory complaints.

Further research is required to assess the implications of the current study in the context of the current COVID-19 pandemic.
