A healthy diet can relieve respiratory symptoms, according to study

A healthy diet can relieve respiratory symptoms, says study

According to scholars, good nutrition is one of the ways to take care of our health. A diet rich in fiber, fruits and vegetables, for example, can relieve respiratory symptoms of asthma. At least that’s what the research published in the scientific platform “European Respiratory Journal” says.

The study does not concern COVID-19 but found that healthier eating behaviors were associated with fewer asthma symptoms and greater disease control.

Asthma is one of the most common chronic diseases in the world and affects about 358 million people. Some of its symptoms are coughing, shortness of breath and wheezing.


A detailed respiratory questionnaire was applied in 2017 to 34,766 French people over 18 years of age. Of these, approximately 25% reported at least one symptom of asthma. Participants who had a high intake of fruits and vegetables – that is, foods with a high fiber content – had a result “relevant to primary and secondary prevention of asthma”.

Asthma symptoms and control and the quality of dietary data were evaluated based on at least three food records in 24 hours over an eight-year period, reflecting the participants’ eating habits.

“In summary, our results support the hypothesis that a healthy diet, an important contributor to good health, may also be relevant in preventing asthma and its lack of control,” concluded the study. “Our results expand and justify the need to continually propagate public health recommendations to promote healthy dietary behaviors.”

In 2013, another research related to asthma had found that young people who frequently ate fast foods were more affected by the disease. Published in Science Translational Medicine, the study analyzed data from 319,196 adolescents (aged 13 to 14) from 107 centers in 51 countries and 181,631 children (aged 6 to 7) from 64 centers in 31 countries.

The conclusion was that eating fast food three or more times a week was associated with a 39% higher risk of severe asthma in adolescents and a 27% higher risk among children.

“On the other hand, eating fruit three or more times a week was associated with a decrease of 11% in the prevalence of severe asthma in adolescents and 14% in younger children”, found Marina Reznik, responsible for the study.
