A study published in Respiratory Medicine (July 14, 2010, e-published ahead of print) compared subjects with asthma and grass pollen allergy with healthy controls. The ratio of omega-3 to omega-6 fatty acids were significantly lower in the asthmatic patients than in the healthy controls (as measured in the erythrocyte membranes). Symptoms were proportionally worse in the patients with the lowest levels of omega-3 fatty acid, with those patients exhibiting higher bronchial reactivity. This may indicate that omega-3 fatty acid supplementation may be beneficial to asthmatics.
