Mechanism of the Health-promoting Effects of the Food Ingredient
Evidence suggests that the biological effectiveness of CLA are due to the separate actions of cis- 9, trans 11 and trans- 10, cis 12 isomers.It is likely that numerous health effects are enhanced by synergistic actions of these isomers. Findings such as, inhibition of chemically induced carcinogenesis, enhanced immune system, reduction of atherosclerosis, enhanced growth, fat reduction are attributed to a mixture of these CLA isomers (Pariza, Park, & Cook, 2001).
Weight reduction
Researchers have theorized about the many mechanisms CLA have an effect on. Some proposed mechanisms such as reduction of proliferation and differentiation of preadipocytes, decreased esterification

Insulin resistance can also be caused by increased triglycerides and free fatty acids intake. This is due to the effect Triglycerides and free fatty acids have on insulin stimulated signal pathways, translocation protein-4 and glucose uptake (Choi, Jung, Park, & Song, 2004). It is found that CLA has a regulatory effect on glucose and lipid metabolism regulators. CLA affects the PPAR-y ligand, a major receptor that influences the expression and transcription of genes that are related to the metabolic effects of glucose and lipids. Such protein regulators as aP2, insulin-dependent glucose transporter 4, FATp, ACS and adiponectin are all influenced by increased CLA. (Xiao-Rong Zhoua, Chang-Hao Suna, Jia-Ren Liua, b, Dan Zhaoa, 2008). It was also theorized that CLA may act on other glucose regulators such as phosphoenolpyruvate carboxylase, glucose-6-phosphate, glucokinase, sterol-regulation element finding protein, acyl coenzyme A oxidase, fatty acid synthase and uncoupling protein. Testing done on rats with a mixture of cis 9, trans 11 and trans 10, cis 12 CLA had found that the only effected regulatory agents were regulators involved in gluconeogenesis such as Phosphoenol carboxykinase and transcriptional factors, sterol-regulating element binding protein-1c and PPAR-y (Choi, Jung, Park, & Song, 2004). The main regulatory effect on insulin resistance was the effect on ligand PPAR-y, a key regulator in lipid homeostasis. Mixtures of CLA isomers consisting of cis 9, trans 11 and trans 10,cis 12 effect gene expression of PPARy mRNA in rats. It was found to have affected the levels of aP2, FATP, ACS and adipoenectin mRNA expression in adipose tissue. CLA increased These regulatory proteins resulting in an uptake of free fatty acids into the adipose tissue and decreasing uptake into the muscle tissue. This has been found to improve muscle insulin
