Kangaroo meat - health secret revealed

23.04.2004


The meat of Australia’s bush kangaroo may be the highest known source of the healthy fat CLA, a University of Western Australia and CSIRO sponsored PhD student has discovered.



CLA (conjugated linoleic acid) is found in dairy products, beef and lamb.

In trials, CLA has been shown to possess potential anti-carcinogenic and anti-diabetes properties, in addition to reducing obesity and atherosclerosis (high blood pressure). PhD student Clare Engelke has found that the meat-fat of the Western Grey kangaroo in some circumstances has up to five times higher CLA content than lamb. "Australian pastoral lamb is considered to be a relatively high source of CLA, so I was surprised to find the levels in kangaroos were that much higher in comparison," Ms Engelke said.


Her study is believed to be the first research on CLA levels in kangaroos available in the public domain.

In collaboration with the University of Adelaide, Ms Engelke compared CLA levels in Western Grey kangaroos and lambs from the Badgingarra region in Western Australia and analysed tissue samples of other Western Greys, Red and Eastern Grey kangaroos from different areas of Australia. Although kangaroos are not a true ruminant, Ms Engelke became interested in researching Australia’s national icon for her PhD in agricultural science because, like ruminants, kangaroos ferment food in their foregut. CLA is produced in the stomach and tissues of ruminant animals such as sheep and cattle during the digestion process. In Australia, kangaroo meat has traditionally been used for pet food but the European market for the meat grew by 30 percent following the 2001 outbreak of foot and mouth disease.

CSIRO Project Leader Dr Andre Wright said kangaroo meat was very lean with a two per cent fat content. "Kangaroo meat also has high levels of protein, iron and zinc," Dr Wright said.

Ms Engelke is now working to identify the ’bugs’ in the kangaroo’s foregut responsible for producing CLA. "My aim is to find out which microorganisms and circumstances are responsible for CLA formation and why kangaroo meat appears to be the highest known source of these healthy fats," Ms Engelke said.

If successful, it may be possible to increase the CLA content of other meats and products to increase potential health benefits to consumers.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
