The present study compared the effects of feeding dried grape pomace (DGP) or citrus pulp (DCP) at 150 g/kg dry matter to a control diet on major polyunsaturated fatty acids (PUFA), volatile and sensory profiles beef. Feeding DGP DCP diets Angus steers for 90 d increased proportions C18:2n-6, C20:4n-6, C18:3n-3, total conjugated linoleic acid (CLA), n-3 n-6 PUFA in muscle. Control-fed beef had ...

In vitro experiments have shown that isolated human gut bacteria are able to metabolise PUFA into conjugated PUFA like conjugated linoleic acids (CLA). The hypothesis of the present paper was that high-fat (HF) diet feeding and supplementation with fermentable carbohydrates that have prebiotic properties modulate the in vivo production of CLA by the mouse gut microbiota. Mice were treated for 4...

The current literature suggests that linolenic acid biohydrogenation converts to stearic acid without the formation of CLA. However, a multitude of CLA were identified in the rumen that are generally attributed to linoleic acid biohydrogenation. This study used a stable isotope tracer to investigate the biohydrogenation intermediates of C-linolenic acid, including CLA. A continuous culture ferm...

Background Green tea, caffeine, conjugated linoleic acid (CLA), and branched chain amino acids (BCAA) have shown to individually improve body composition and metabolic rate in overweight and obese individuals. The purpose of this study was to investigate the effects of a multi-ingredient dietary supplement (MIDS) containing these ingredients on body composition, lipid profile, and metabolic rat...

Conjugated linoleic acid (CLA) is a naturally occurring group of dienoic derivatives of linoleic acid found in the fat of beef and other ruminants. CLA is reported to have effects on both tumor development and body fat in animal models. To further characterize the metabolic effects of CLA, male AKR/J mice were fed a high-fat (45 kcal%) or low-fat (15 kcal%) diet with or without CLA (2.46 mg/kca...

Excessive intake of saturated fatty acids and/or linoleic acid favors the induction of an array of lipid mediators and cytokines enhancing inflammatory responses. Conversely, dietary supplementation with (n-3) fatty acids or vitamin D ameliorates inflammation and autoimmune diseases. Although it was well accepted that conjugated linoleic acid (CLA) prevented diseases with a common inflammatory ...

Conjugated linoleic acid (CLA; 9c,11t-18:2) and CLA isomers have been reported, in animals, to exhibit a variety of health-related benefits. Silver ion high-performance liquid chromatography (Ag-HPLC) was found to provide better resolution of the isomers than gas chromatography. Most commercially available samples of CLA, prepared by base-catalyzed isomerization of linoleic acid (9c,12c-18:2), ...

Conjugated linoleic acid (CLA) is reported to have health benefits, including reduction of body fat. Previous studies have shown that brown adipose tissue (BAT) is particularly sensitive to CLA-supplemented diet feeding. Most of them use mixtures containing several CLA isomers, mainly cis-9, trans-11 and trans-10, cis-12 in equal concentration. Our aim was to characterize the separate effects o...

Aging is a major risk factor for cognitive decline, such as Alzheimer’s disease (AD). Sheep’s milk may play role in the prevention of neurodegenerative diseases because its high content functional peptides, lactoferrin. Lactoferrin can be used AD both an active therapeutic compound and drug nanocarrier. Compared to cow’s goat’s milks, sheep’s contains highest isomers conjugated linoleic acid (C...
