In Ireland produced cow milk is healthier than milk produced in other countries, according to Irish research. The Irish research institutes Teagasc and Food for Health Ireland compared milk produced on the ration with a lot of grass, which is mainly used in Ireland, with a ration with a medium share of grass and a ration with little grass, which is most often used elsewhere in the world. The milk produced on the Irish ration contained up to 83 percent more omega-3 fatty acids; up to 141 percent more conjugated linoleic acids (CLA); the highest content of unsaturated fatty acids (including monounsaturated and polyunsaturated) and the lowest content of saturated fatty acids.
