BACKGROUND & OBJECTIVES Conjugated linoleic acid (CLA) reduces fat deposition in the body, but the mechanism of action is not clear. The present study was conducted to investigate the effects of CLA on body fat metabolism. Since milk fat is the best natural source of dietary CLA, intervention of non-fat milk constituents on CLA treatment was also investigated. METHODS Diets containing CLA (1%...
Beef strip loins (IMPS 180; n=15) were sectioned in thirds and sections (n=45) were left untreated (CNT) or injected with either a commercial powder conjugated linoleic acid (CLA) source (Powder) or a commercial oil CLA source (Oil), whose major isomers were 18:2cis-9, trans-11 and 18:2trans-10, cis-12 CLA isomers. Fresh Oil steaks had 3.20 and 3.15, Powder steaks had 4.67 and 4.62, and CNT ste...
OBJECTIVE To determine effects of conjugated linoleic acid (CLA) on establishment and progression of experimentally-induced atherosclerosis in rabbits. METHODS For establishment of atherosclerosis, New Zealand White rabbits were fed a semipurified diet containing 0.1% to 0.2% cholesterol for 90 days. Some groups were fed diet and CLA. For effects on progression of atherosclerosis, rabbits wit...
Dietary oils containing large amounts of conjugated linolenic acids (CLnA) may be regarded as a source of conjugated linoleic acids (CLA), which have been suspected to bear health-promoting properties. Indeed, CLnA can be converted into CLA in mammals. The objective of the present study was to investigate the uptake of CLnA and their metabolism into CLA in Caco-2 cells, as a validated in vitro ...
Milk fat contains several compounds with known anti-carcinogenic properties. One of these is conjugated linoleic acid (CLA), and dairy products are the major source of CLA in human diets. In addition to its anti-cancer effects, biomedical studies with animal models have demonstrated that CLA has a range of beneficial effects. The processes for the biosynthesis of CLA in dairy cows have been est...
Conjugated linoleic acid (CLA), a mixture of isomers of linoleic acid, has previously been shown to be able to decrease porcine subcutaneous (SC) adipose tissue levels while increasing the count of intramuscular (IM) adipose tissue in vivo. However, the underlying mechanisms through which it acts are poorly understood. The objective of this study was to investigate the different effects of CLA ...
Peroxisome proliferator activated receptors (PPARs) represent a family of DNA binding proteins that are activated by a variety of dietary and endogenous fatty acids. The PPAR proteins are expressed throughout the body and are the target of a variety of lipidaemic and insulin sensitizing drugs. Conjugated linoleic acid (CLA) is a collective name for octadecadienoic acid isomers with conjugated d...
The aim of this study was to determine and compare in situ biohydrogenation (BH) fatty acids in three forms of soybeans and linseed (raw, extruded and roasted). Nylon bags (5×10 cm) containing 4 g of raw, extruded or roasted soybeans or raw, extruded or roasted linseed were incubated in the rumen of fistulated ewes for 4, 8, 12 and 24 hours. Results for linoleic acid (C18:2) showed tha...
This study was designed to detemine if conjugated linoleic acid (CM) is incorporated into egg lipids through dietary CLA supplernentation. Forty Single Comb White Leghorn layen (28 weeks of age) were randomly assigned into four treatments of varying CLA levels, 0, 0.01, 0.5 and l g C W k g diet. C U replaced an equivalent arnount of linoleic acid in the diet. Eggs were collected over 36 days. F...
The human health aspects of dietary fatty acids have been in the focus of nutritional studies. Several experiments have revealed that dietary conjugated linoleic acid (CLA) has anticancer activity, antiartherogenic effects, reduces body fat gain and enhances immune responses (PARIZA et al., 2000). The term CLA refers to a group of positional and geometric isomers of linoleic acid. The cis-9, tr...
