A study of the metabolic effects of omega-3 fatty acids, especially DHA, concludes that these compounds may have an even wider range of biological impacts than previously considered, and suggests they could be of significant value in the prevention of fatty liver disease. The research, done by scientists at Oregon State University, OSU’s College of Public Health and Human Sciences, and several other institutions, was one of the first of its type to use “metabolomics,” an analysis of metabolites that reflect the many biological effects of omega-3 fatty acids on the liver. It also explored the challenges this organ faces from the “Western diet” that increasingly is linked to liver inflammation, fibrosis, cirrhosis, and sometimes liver failure.
