The researchers studied how adding two types of fatty acids, EPA and DHA, to human airway cells affects their composition. They found that EPA and DHA can change the types of fatty acids in the cells, leading to lower inflammation. EPA decreased certain fatty acids and increased others, while DHA had similar effects. Both EPA and DHA raised the ratio of beneficial fatty acids to harmful ones in the cells. Overall, adding EPA and DHA can alter the fatty acid content of airway cells in a way that reduces inflammation.
