Nutrition and asthma

Area of Science:

• Pulmonology
• Nutrition Science
• Immunology

Background:

• Asthma is a complex respiratory syndrome characterized by airway inflammation and hyperresponsiveness.
• Potential causes investigated include genetic, atopic, viral, and nutritional factors.
• Nutritional factors have been studied for two decades regarding their role in asthma etiology and management.

Purpose of the Study:

• To review and analyze existing data on nutritional therapy for asthma.
• To determine the role of specific nutrients and supplements in asthma management.
• To evaluate the impact of nutritional interventions on asthma symptoms and control.

Main Methods:

• Systematic review and analysis of studies investigating nutritional factors in asthma.
• Examination of data on suboptimal nutrient status as a cause of asthma.
• Assessment of studies on specific nutrient supplements as asthma therapy.
• Analysis of research on food allergies and their association with respiratory symptoms.

Main Results:

• IgE-mediated food allergies are a minor cause of respiratory symptoms, more prevalent in children than adults.
• Current data does not support the efficacy of nutritional supplements for treating chronic asthma.
• Suboptimal nutrient status has been explored as a potential contributor to asthma development.

Conclusions:

• Nutritional therapy currently lacks robust evidence for the management of chronic asthma.
• While food allergies can cause respiratory symptoms, their role in asthma is limited.
• Further research may be needed to clarify the precise role of nutrition in asthma care.
