CLA, “new nutrients”?
2005
International audience; Conjugated linoleic acid (CLA) refers to a class of positional and geometric dienoic isomers of linoleic acid. Chronic dietary supplementation with commercial isomeric mixtures sold as dietary supplements leads to a drop in fat mass in various species. The t10,c12-CLA isomer is responsible for this antiobesity effect.The reduction of fat mass is especially dramatic in the mouse, in which it is associated with a severe hyperinsulinemia, an insulin resistance and a massive liver steatosis. The origin of these adverse side effects and the putative chronology of events leading to CLA-mediated lipoatrophic syndrome are presented and discussed in this review. In Human, the…
Effects of dietary conjugated linoleic acids in the control of adiposity and obesity‐related disorders
2007
The body fat-lowering effect of conjugated linoleic acids (CLA) in experimental animals has attracted much interest because of the potential use of CLA as weight loss agents in humans. The objective of this review was to give an overview of the results from human intervention trials. The review also addresses experimental studies in animal models and in cultured cells. CLA appear to provoke fat mass loss and an increase of fat-free mass in rodents, but the results in humans are inconsistent and much less clear than in rodents. Thus, the results of studies in humans do not support a body fat-lowering effect of CLA. There are indications from animal studies that the trans-10, cis-12 CLA isome…
Effet anti-obésité des CLA : mythe ou réalité ?
2005
Conjugated linoleic acids (CLA) are positional and geometric isomers of linoleic acid. Inclusion of CLA in the diet provokes a rapid and marked decrease in body weight gain and adiposity in mice leading to a lipoatrophic syndrome. However, CLA supplementation raised fasting blood glucose and insulin concentrations and was associated with severe insulin resistance and liversteatosis. Conflicting results have been reported with regard to reduction of fat mass in humans. We have reviewed the publish literature regarding the effect of CLA on body composition in humans and animal models. These studies indicate that t10-c12 was the isomer that reduced adipose fat storage, however it also increase…
