A study suggests that the odds of having severe asthma increased 48% among people on a high-fat, low-fiber diet. Researchers are still working to understand the link between diet and asthma, including an observed link between asthma and obesity. "Fat intake is important in people with asthma as it is pro-inflammatory, and can reduce the response to bronchodilator (rescue inhaler). ... Lower fiber intake was related to poorer lung function and increased airway inflammation in people with asthma," said study researcher Bronwyn Berthon.
