Why are formulas containing omega-3 fatty acids recommended in ALI and ARDS? correct
answersInflammatory mediators, including prostaglandins and leukotrienes derived from arachidonic
acid metabolism have been implicated in both ALI and ARDS. Formulas containing omega-3 fatty acids
may down regulate the inflammatory response through the production of less inflammatory
prostaglnadins and leukotrienes

What is the evidence for use of omega-3 fatty acids in ARDS and ALI? correct answersBased on 3 level 1
studies the Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult

guidelines and recommendations have been studies published in 2011 showing that enteral

, supplementation of omega-3 fatty acids did not result in improved biomarkers of inflammation or clinical
outcomes

encephalopathy symptoms.
