Significant Vitamins Might Protect Against Common Cold

Key Takeaways:

• Recent study suggests individuals with an adequate intake of Vitamins A, D, and E appear less likely to develop common respiratory complaints including coughs and sore throat.
• There are limitations to the study, such as a small sample size, and it does not definitively establish that vitamins protect against respiratory ailments. It only indicates a possible correlation.
• Further studies are planned to establish a more definite relationship between vitamin intake and risks of respiratory symptoms.
• While Vitamin D deficiency has been linked with severe COVID-19 complications in some studies, a definitive cause and effect relationship has not been established.
• Experts recommend regular blood checks to monitor vitamin D levels and suggest supplements if necessary. A balanced diet is also encouraged for adequate intake of Vitamins A and E.

Individuals who ensure an adequate intake of Vitamin A, D, and E appear less prone to develop common cold symptoms such as a sore throat or a cough. However, it is uncertain whether the mitigated symptoms are directly related to these vitamins, according to recent investigations.

Research Study Overview

The research encompassed more than 6,100 adults from the UK. Findings highlighted that participants with a higher intake of vitamins were less likely to report “respiratory complaints” – a category encompassing symptoms from coughs, chest infections to difficulties in breathing and a sore throat. Vitamins A and E, whether absorbed from food or supplements, along with vitamin D from supplements, were associated with a smaller likeliness of respiratory problems. Nevertheless, these findings do not automatically establish that vitamins protect against respiratory diseases.

Study Limitations

Criticisms for the study do exist. For example, only a minuscule amount of 33 people in the study reported respiratory complaints, and the exact cause behind their symptoms, be it chronic lung conditions or temporary infections, remains ambiguous. Consequently, this study like many others of its type can only suggest correlations rather than establish definitive cause and effect relationships.

Dr. Daniel Jobe, a non-participant in the study, remarks, “It’s important to remember that even if two things occur together, they may not actually be related,” He further adds, “It may be a coincidence, and one thing may not be the cause of another.” Jobe warns against drawing conclusions based on the small number of people reporting a broad array of symptoms that lacks in specificity.

Future Research and Conclusion

Suzana Almoosawi, the lead investigator of the study, indicated that her team looks forward to conducting additional studies in long-term cohorts to establish a more definite relationship between vitamin intake and lower risks of future respiratory symptoms.

Sources of Vitamins

Vitamin A can be derived from red and orange vegetables, dairy products, and fortified cereals. On the other hand, vitamin E sources include vegetable oils, nuts and seeds, and leafy green vegetables. It has also been determined that higher levels of Vitamin A, E and D intake corresponded with fewer reported respiratory issues.

Vitamin D deficiency has been indicated as potentially troublesome in the context of severe COVID-19 infections in a few studies. It has been observed that patients with adequate vitamin D levels are less likely to face severe COVID-19 complications than those with lower levels. Nonetheless, a cause and effect relationship hasn’t been definitively established yet.

In conclusion, experts recommend adults and children get 600 IU of vitamin D a day, increasing to 800 IU for adults aged over 70. As it is challenging to obtain enough vitamin D from food alone, Dr. Jobe suggests people check their blood levels of vitamin D and take a supplement if necessary. Apart from this, a balanced diet that includes fruits, vegetables, plant oils, and nuts should guarantee an adequate intake of vitamins A and E. However, more comprehensive research is needed to determine whether these vitamins help combat respiratory ailments.
