Scientists have uncovered yet another incredible benefit of the Mediterranean diet, one that could be particularly relevant in today’s world. A new analysis suggests that eating a diet rich in vegetables, fruits, nuts, and oily fish could significantly reduce your risk of developing severe Covid-19 symptoms.
The Mediterranean diet has long been praised as the secret behind the long, healthy lives of Italians and Spaniards. These countries enjoy low rates of obesity and diet-related illnesses, thanks to their dietary habits. This diet has been shown to reduce inflammation, improve the body’s regulation of insulin, and help manage weight, all of which contribute to reducing the risk of heart disease, dementia, and diabetes.
Cutting the Risk of Severe Covid
Recent research conducted by a university in Indonesia has added to the growing list of benefits associated with the Mediterranean diet. Researchers analyzed the results of six previous studies involving over 55,000 people to understand the impact of this diet on Covid-19 outcomes. Remarkably, four of these studies found that individuals who adhered to a Mediterranean diet were less likely to develop severe symptoms of Covid-19.
A high temperature, fever, cough, sore throat, and runny nose are common signs of Covid-19. The studies revealed that people who followed the Mediterranean diet had a lower likelihood of experiencing these severe symptoms. Although some studies did not find conclusive evidence on the differences in disease severity, researchers believe the diet could offer some level of protection.
Measuring Adherence to the Diet
Adherence to the Mediterranean diet was measured using questionnaires that included categories such as vegetables, fruits and nuts, cereals, legumes, fish, red meat, and dairy. The ratio of monounsaturated to saturated fat was also an essential component in determining the Mediterranean diet score.
Supporting Immune Function
Several studies have acknowledged how the body protects itself against viral respiratory infections. One previous study found that consuming healthy plant-based foods was associated with lower odds and severity of Covid-19. Another significant finding was that the Mediterranean diet helped patients with recurring colds and frequent inflammatory complications, significantly reducing episodes and symptoms.
A systematic review previously found that the Mediterranean diet lowered inflammatory biomarker levels in obese and overweight adults. Similarly, a meta-analysis reported that adherence to the Mediterranean diet effectively reduced SARS-CoV-2 infection by 78 percent.
Overall Health Benefits
While the study authors did not reveal whether those involved had received vaccinations against the virus, the diet is thought to improve overall health. This improvement is primarily due to the diet’s role in weight management, which also helps prevent heart disease, diabetes, and other conditions.
Other Notable Findings
A separate study published earlier this year found that the Mediterranean diet reduces the risk of death by nearly a quarter in women. The study, which followed more than 25,000 healthy middle-aged American women with an average age of 55, found that those who adhered to a diet rich in fish, legumes, vegetables, nuts, and whole grains had a 23 percent lower risk of dying by the end of the 25-year study period.
The Mediterranean diet continues to prove its worth as a cornerstone of healthy living. From reducing the risk of severe Covid-19 symptoms to lowering the chances of heart disease and improving overall longevity, this diet offers a wealth of benefits. Whether you’re looking to boost your immune system, manage your weight, or simply live a longer, healthier life, the Mediterranean diet might just be the key.
