AGI – A diet based on vegetables and fish can help reduce the chances of developing a severe covid infection. According to a study published in the journal BMJ Nutrition Prevention & Health after several researches had suggested that diet may play a role in the severity of symptoms and the duration of the disease.
The researchers based their analysis on the answers given by over two thousand doctors and nurses with extensive exposure to the virus in France, Germany, Italy, Spain, the United Kingdom and the United States. The participants were part of a global network of health professionals enrolled in Survey Healthcare Globus. The researchers used the network to identify physicians at high risk of infection due to their work.
The online survey, which took place between July and September 2020, was designed for obtain detailed information on the dietary patterns of respondents, based on a questionnaire on the frequency of the various foods during the previous year and on the severity of any covid infection.
The survey also collected information on personal history, medical history, drug use and lifestyle. The various diets were combined into vegetables, fish, and low-carb, high-protein diets. Potentially influencing variables were considered for the study, such as age, ethnic origin, medical specialty, and lifestyle (smoking or exercise).
Respondents who said they followed vegetable or fish-based diets were 73% and 59% less likely to have moderate to severe COVID-19 infection, respectively, than those who did not have these dietary patterns.
Those who claimed to have followed a low-carb, high-protein diet They were nearly 4 times more likely to get moderate to severe covid infection.
Experts point out that the study does not allow to establish a causebut rather a correlation. Plant-based diets are rich in nutrients, vitamins and minerals, all of which are important for a healthy immune system, while fish is an important source of vitamin D and omega-3 fatty acids, both of which have anti-inflammatory properties. the researchers point out.
