FINE, L-B. e DAVIDSON, B.C.. Comparison of lipid and fatty acid profiles of commercially raised pigs with laboratory pigs and wild-ranging warthogs. S. Afr. j. sci. [online]. 2008, vol.104, n.7-8, pp.314-316. ISSN 1996-7489.
The perception that commercial livestock meat products have adverse nutritional effects, especially from the point of view of lipids and cardiovascular disease, is linked to assumptions concerning their inherent lipid profile. However, when commercially reared domestic pig meat samples were compared with those from laboratory pigs or wild-ranging warthogs, the warthog and laboratory pig samples shared similar lipid profiles, whereas the commercially reared pig samples were different. Pork is not inherently high in saturated fatty acids, unless this has been induced by the current intensive agricultural practices employed in raising the animal. We conclude that problems of high saturated fatty acid content in commercially raised pork could be ameliorated by appropriate changes to current intensive animal production methods.
