Ruminant meat as a source of conjugated linoleic acid (CLA)

Summary Ruminant meat is a natural source of conjugated linoleic acid (CLA). Evidence has shown that CLA has many potential health benefits on cancer, coronary heart disease and diabetes. However, to date, all of the published research has been conducted in animals and there are few data in relation to the potential health benefits of CLA in humans. Lamb is the richest meat source of CLA. The main CLA isomer found in meat is c9,t11. Research has shown that cooking or storing meat does not alter its CLA content, but it can be changed by manipulating the diet of the animal. Little information is available that quantifies the contribution of meat to CLA intake. More research is required to further improve our knowledge on the role that meat can play as a vehicle that naturally supplies dietary CLA.
