According to a research conducted by University of Rochester Medical Centre, scientists collected blood from 17 asthma patients and found that omega 3 fatty acid products can reduce the antibodies that cause allergic reactions and asthma symptoms in people with milder cases of asthma.
But in patients with severe asthma who use high doses of oral steroids, the omega-3 fatty acids are less effective because the corticosteroids block the beneficial effects.
People with asthma have an imbalance between molecules that dampen inflammation and those that increase inflammation. Using steroids as treatment controls the inflammation and relieves symptoms, but does not cure the underlying disease.
