Fish oil supplements, once touted as the natural substance that could alleviate many of your chronic ailments, may not prove to be helpful to obese/overweight adolescents and young adults with uncontrolled asthma, new research suggests.
The study, published in the American Journal of Respiratory and Critical Care Medicine, showed that four grams of fish oil a day for six months did not improve asthma control, as measured by a standard asthma control questionnaire, breathing tests, urgent care visits and severe asthma exacerbations.
"We don't know why asthma control in obese patients is more difficult, but there is growing evidence that obesity causes systemic inflammation," said lead author Jason E. Lang, Associate Professor at the Duke University in the US.
"Because the omega-3 fatty acids in fish oil have anti-inflammatory properties, we wanted to test whether fish oil would have therapeutic benefits for these patients," Lang added.
The team included nearly 100 overweight or obese participants aged 12 to 25 and found that the participants had poor asthma control despite using a daily inhaled corticosteroid to control their asthma.
