The Mediterranean diet has gained popularity in recent years due to its healthy mix of plant-based foods, healthy fats, and whole grains. Studies have linked following a Mediterranean diet to lower blood pressure, cholesterol, and blood sugar levels, as well as a decreased risk for diseases such as type 2 diabetes, obesity, cardiovascular disease, and cancer. Researchers from the Universitas Sumatera Utara in Indonesia have now reported that following a Mediterranean diet may also lower the risk of COVID-19, caused by the SARS-CoV-2 virus. The study analyzed data from six observational studies with a total of over 55,000 participants and found a potential correlation between adherence to the Mediterranean diet and a reduced risk of COVID-19 infection.
According to Andre Marolop Pangihutan Siahaan, MD, a staff member of the Department of Neurosurgery at the Universitas Sumatera Utara, the Mediterranean diet is known for its benefits in chronic diseases such as cardiovascular disease and diabetes. He explained that the diet is associated with immunomodulation and anti-inflammatory factors, which are important in combating COVID-19. The study found that adherence to the Mediterranean diet was associated with lower odds of COVID-19 infection, although the exact extent of the reduction was not determined. Siahaan emphasized the importance of further research to fully understand the long-term impact of the diet in relation to COVID-19.
Monique Richard, a registered dietitian nutritionist, noted that individuals with a more anti-inflammatory dietary pattern, similar to the Mediterranean diet, tended to have better outcomes when affected by COVID-19. She highlighted the importance of consuming fruits, vegetables, and other plant-based foods rich in immune-supportive nutrients to help boost the immune system. David Cutler, MD, a family medicine physician, emphasized the importance of preventative measures such as wearing N95 masks to prevent COVID-19 infection. He stated that while the Mediterranean diet may have some influence on COVID outcomes, the most important factor is preventing the virus from spreading.
As virus season approaches, individuals may be wondering how they can reduce their risk of infection not only from COVID-19 but other viruses such as the flu. Meeting with a registered dietitian nutritionist to personalize dietary recommendations is recommended. Foods rich in immune-supportive nutrients such as vitamins A, B, C, D, E, minerals like zinc, magnesium, and selenium are important for immune health. Consuming a variety of fruits, vegetables, whole grains, proteins, and healthy fats is essential. Richard also cautioned against excessive use of dietary supplements, as they may not have the same impact as whole foods and could lead to nutrient imbalances.
In conclusion, following a Mediterranean diet may help lower the risk of COVID-19 infection, as suggested by recent research. The diet’s anti-inflammatory properties and immune-boosting nutrients can support overall health and potentially provide protection against viruses. While diet plays a role in improving outcomes, preventative measures such as wearing masks remain crucial in preventing the spread of COVID-19. By adopting a Mediterranean diet rich in plant-based foods, individuals can enhance their immune system and reduce their risk of infection during virus season.
