A healthy human nutrition stems from macronutrients that provide energy and also from micronutrients that are indispensable for basic physiological processes. Essential fatty-acids have been proved and commonly agreed in the recent years as important elements of a healthy diet. This gives impetus to look for sources of essential fatty-acids in the diet. Beef is not only considered a complete protein, but also a source of essential fatty-acids such as linoleic and linolenic acids. The levels of these fatty-acids are however variable depending on the diet and breed of cattle. In this work, we analyzed intra-muscular fatty acid profiles of two breeds (Aberdeen Angus and Blonde d'Aquitaine) as a part of long-term complex and comprehensive comparison of breed differences. Using a novel statistical algorithm we found interesting breed-specific fatty-acid profiles. The advantages of this approach over conventional approaches are discussed as well as the specific differences in fatty acid profiles between the breeds.
