Dietary interventions in exercise-induced bronchoconstriction

Asthma is an inflammatory disease of the airways that affects over 7% of the world’s population (Papi et al., 2018). Exercise-induced bronchoconstriction (EIB) is a type of asthma which is defined as a transient narrowing of the airways in response to exercise and affects 90% of asthma sufferers and up to 15% of non-asthmatic individuals (Bonini & Usmani, 2018). Asthma and EIB can be managed either by rapid bronchodilatation to relieve respiratory symptoms or long-term suppression of inflammation. However, frequent use of reliever medicines can lead to the user becoming tolerant to the treatment and long-term control medicines. They also have several undesirable side effects including elevated cholesterol and triglyceride levels, and an increased risk of diabetes, osteoporosis, ulcers and gastritis. This has led to poor adherence amongst patients.


Dietary and supplement interventions have been reported to reduce the effects of asthma and EIB (Williams et al. 2016). These may represent a cost-saving, effective and safe method for reducing the incidence of asthmatic attacks. However, it is currently unknown how many individuals with asthma and EIB use diets and supplements to help manage their asthma and EIB and whether these individuals believe that these lead to an improvement in their lung function and respiratory symptoms.


The aim of this project is to investigate diet and supplement usage and perceived benefits in patients with asthma and exercise induced bronchoconstriction.


The inclusion criteria are individuals over the age of 18 years old, English speaking and with physician diagnosed asthma. This survey comprises of questions regarding demographics, asthma control physical activity and supplement usage. Approximately 15 to 30 minutes will be required to complete the survey.
