Diet linked to asthma symptom severity


Dietary intake is an important modifiable risk factor for asthma. Through the effects of intake of anti-oxidant-rich foods and pro-inflammatory nutrients, diet may affect asthmatic disease severity and inflammation.

A recent Australian study, which explored the connection between obesity and asthma, found that diet was associated with asthma severity and that fat is positively associated with airway inflammation and more severe symptoms.

In contrast, asthma suffers who ate a diet rich in fiber and antioxidants were found to experience less severe symptoms.

This study shows the importance of a healthy nutritional diet for asthma sufferers.
