Fruit and vegetables can help prevent asthma, a review of published research has stated. The review has concluded that eating a plant-based diet can alleviate or reduce symptoms of asthma.
Asthma is a chronic inflammatory condition in which a person’s airways become inflamed, causing wheezing and difficulty breathing.
The Centers for Disease Control and Prevention (CDC) estimated that in 2018, in the United States, asthma affected around 7.7% of people and killed 3,441 people.
Exposure to an allergen or irritant, such as pollen or cigarette smoke, vigorous exercise, and emotional stress trigger signs and symptoms of asthma.
Doctors have explained that obesity is a risk factor for the disease. According to a 2019 study in Annals of the American Thoracic Society, people with obesity and asthma can reduce symptoms by losing weight.
Recently a new review published in Nutrition Reviews has found that eating fruits and vegetables can help reduce the risk of developing the condition and improve symptom control. The review also added that dairy products increase risk and worsen symptoms.
Researchers in this new study analyzed the associations between asthma and the consumption of fruit and vegetables, dairy, eggs, and saturated fat.
One of the authors, Dr. Hana Kahleova of the Physicians Committee for Responsible Medicine said, “This groundbreaking research shows that filling our plates with plant-based foods — and avoiding dairy products and other high-fat foods — can be a powerful tool for preventing and managing asthma.”
However, major healthcare organizations do not suggest that people reduce their consumption of dairy products or eat a vegan diet.
