This article reports on a study that compared the differences of fatty acid content in grain-fed beef compared to grass-fed beef. The results may surprise most meat-eaters who are health conscious and hope to get their dietary Omega-3 from a meal of red meat.
For marketing and health promotion purposes cuts of meat that meet the Food Standard Australia and New Zealand for Omega-3 fatty acid content can be labeled as such, and only grass-fed beef meets the standard.
