New research from Greece suggests a diet high in omega-3 fatty acids can reduce airway inflammation that leads to asthma attacks, Reader’s Digest reports.

In a clinical trial from by La Trobe University in Greece, researchers recruited 64 children with mild asthma. While half of the children followed their normal diets, the other half got two meals of cooked fatty fish twice a week for six months. After the trial, the researchers found that the kids who ate more fish substantially reduced their airway inflammation.

Lead researcher Maria Papamichael explains in a press release: “Fatty fish is high in omega-3 fatty acids which have anti-inflammatory properties. Our study shows eating fish just twice a week can significantly decrease lung inflammation in children with asthma.”
