Consuming these vitamins prevent respiratory problems


Adata analysis of nationally representative long-term surveys in UK have shown that the intake of Vitamin A, vitamin E and vitamin D It could be related to a lower risk of developing breathing problems.

These data have been published in the journal ‘BMJ Nutrition Prevention & Health’. Thus, these findings suggest new studies among different ethnic groups and geographies in view of the current Covid-19 pandemic.

In this sense, it is important to highlight that nutrition plays a key role in reducing the risk of certain infections. Of course, immunity is complex and it is difficult to fully understand this operation.

The European Union has stated that the consumption of vitamins A, E, C and D contribute to improving the functioning of the immune system. For its part, American Nutrition Association it also suggests that these vitamins are beneficial in reducing the chances of respiratory infection.

The effects of vitamin A

The investigators who authored this study were able to observe only dietary intake (continuous exposure) and supplements (binary exposure). In addition to influencing factors such as gender, age, weight, smoking, family income and total energy intake.

A total of 33 respondents had respiratory problems, all of them generally older and less likely to regularly take vitamin A, E, C or D supplements.

There was no clear association between body mass index and vitamin intake; as well as between respiratory discomfort and body mass index. It was also not possible to establish any association with vitamin C supplements, since no person with a respiratory condition reported its intake.

However, intake of vitamin A and E in the diet and through vitamin supplements was associated with a lower prevalence of respiratory problems in UK adults.

In this sense, the main sources of vitamin A are beef liver, whole milk, cheese, carrots, dark green leafy vegetables and orange fruits. For their part, the foods richest in vitamin E are vegetable oils, nuts and seeds.

Influence of other micronutrients

In another order, if the intake of vitamin D from supplements was linked to a lower risk of respiratory problems; although the same did not happen with vitamin D from the diet. Therefore, this reignites the debate about these types of supplements.

“It is estimated that around a fifth of the general population in the United Kingdom has low levels of vitamin D, and more than 30% of adults aged 65 years and over do not reach the recommended nutrient intake,” the study states. .

On the other hand, the researchers argue that “our findings are consistent with the hypothesis that supplementation is essential to ensure that adequate vitamin D status is maintained and potentially indicate that vitamin D intake alone cannot help maintain vitamin D status. adequate vitamin D status ».

However, because it is an observational study, it is not possible to determine a cause. Furthermore, the number of respiratory problems was relatively small.

Ultimately, the authors of this illustrative study note that “further research is required to assess the implications of the current study in the context of the current 2019 coronavirus disease pandemic using longitudinal cohort data.”
