As cases of COVID-19 continue to surge, a new study suggests that following the Mediterranean diet might offer some protection against infection. Published in the journal PLOS One, Indonesian researchers found that this healthy eating regimen, which emphasizes fruits, vegetables, whole grains, legumes, fish, and heart-healthy fats like olive oil and nuts, can lower the risk of contracting COVID-19.
The study, led by senior author Andre Siahaan, a lecturer at the Center of Evidence-Based Medicine at the University of North Sumatra in Indonesia, highlights the anti-inflammatory properties of the Mediterranean diet. Inflammation in the body has been closely linked to COVID-19, while the Mediterranean diet has long been known for its ability to reduce inflammation. This study further strengthens the connection between the two, suggesting that this diet could play a role in preventing COVID-19 infection.
While changing one’s diet may not be easy, Siahaan recommends slowly incorporating elements of the Mediterranean diet into daily life. This approach can make it more manageable for individuals to adopt healthier eating habits over time.
Dr. Jordi Merino, an associate professor at the Novo Nordisk Foundation Center for Basic Metabolic Research at the University of Copenhagen in Denmark, commended the findings of the study. He emphasized the importance of optimal nutrition in preventing both communicable and noncommunicable diseases, highlighting the potential public health implications of this research.
The study reviewed six different studies involving over 55,400 participants from five countries. The results showed a significant association between the Mediterranean diet and a reduced risk of COVID-19 infection. Participants who followed this diet had a lower risk of contracting the virus compared to those with less adherence to the Mediterranean diet.
However, the study did not show a clear link between the Mediterranean diet and the severity of COVID-19 symptoms. While some studies reported a reduction in symptoms and severity among individuals following this diet, others did not find a significant relationship. This suggests that more research is needed to fully understand the impact of diet on COVID-19 outcomes.
It’s important to note that the study had some limitations. All the studies reviewed were observational, meaning they could only establish associations between lifestyle factors and health outcomes. Factors other than diet, such as obesity, diabetes, and social disparities, could also influence the results. Additionally, self-reporting of COVID-19 infection may not always be accurate, and the level of exposure to the virus was not measured in the studies.
Despite the potential benefits of the Mediterranean diet, getting vaccinated remains the most effective way to protect against COVID-19-related hospitalization, long-term health consequences, and death. The U.S. Centers for Disease Control and Prevention advises that vaccination is crucial in mitigating the impact of the virus.
In conclusion, while the Mediterranean diet may offer some protection against COVID-19 infection, it should not be seen as a substitute for vaccination. Incorporating elements of this healthy eating plan into your daily routine can be a step towards better overall health and well-being.
