CLA and nutrient absorption -

Mixture of active molecules sharing the same chemical composition, with slightly different structures; mostly cis-9, trans and trans, cis isomers of linoleic acid. Pregnancy potentially lower birth weight in newborns. Please note that CLA absorbed from foods is risk-free; Children ages 12 and under; Liver problems.

Main constituents Mixture of active molecules sharing the same chemical composition, with slightly different structures; mostly cis-9, trans and trans, cis isomers of linoleic acid Main dietary sources of CLA: Meat from ruminants lamb, beef, mutton, goat , milk, and other dairy products.

Sources for the production of CLA supplements: Vegetable oils transformed by chemical reactions. Close medical supervision is therefore necessary for diabetics. The animals fed CLnA as FFA had lower content of arachidonic acid in liver and plasma PL. CLnA metabolites are shown in Table 4.

The cis -9, trans , cis was elongated and desaturated up to cis -4, cis -7, cis , cis , trans , cis while the cis -9, trans , cis was metabolized up to cis -5, cis -8, cis , trans , cis Conjugated metabolites accumulated in both neutral lipids and polar lipids.

However, the cis -7, cis , cis , trans , cis and the cis -4, cis -7, cis , cis , trans , cis were exclusively detected in liver and plasma phospholipids.

No differences in the amount of the metabolites were found between the two dietary forms given FFA or TAG. This suggests that there was no difference in the metabolic fate elongation and desaturation of CLnA when ingested as FFA and as TAG.

Most of the studies so far published on CLA focussed on their putative effects on biological function and prevention of metabolic disorders.

However, few studies considered the effect of the dietary form FFA or TAG on their bioavailabilty and metabolism [ 6 ], while dietary supplement are often available as free fatty acids. The major reason may be that TAG are more expensive. Otherwise, no studies have shown their absorption efficiency in nutritional conditions.

In the present study, the experimental fatty acids RA and CLnA mixture were given as FFA or as randomized TAG and were equally incorporated into tissues Table 2.

No significant differences in absorption levels were found between those two lipid forms. This suggests that the dietary form did not modify the incorporation of RA and of CLnA into tissues under our experimental conditions. These data are in agreement with the study of De Schrijver et al.

While in the present study RA and CLnA were totally absorbed, a previous study using lymphatic recovery showed that a CLA mixture given as FFA was less absorbed than linoleic acid [ 11 ]. No study was so far published on the lymphatic recovery of CLnA. However, it has already been shown that RA absorption as TAG did not behave like a common fatty acid because of its conjugated structure or its trans double bound in Δ 11 position or both [ 13 ].

In the present study, we also demonstrate that CLnA mixture is preferably incorporated into neutral lipids similar to RA.

The incorporation of trans fatty acids in NL has long time been demonstrated with elaidic acid trans -9 and shows that it follows the metabolic pathway of saturated fatty acids [ 14 ]. Moreover, it has been hypothesized by Martin et al. This hypothesis was also sustained by Banni et al.

CLnA competes as well for this enzyme as seen by the lower arachidonic acid content in liver PL in rats fed CLnA.

Metabolites from both CLnA isomers were found in NL as in PL. The cis -9, trans , cis isomer was elongated and desaturated up to n-3 conjugated isomer while cis -9, trans , cis was elongated and desaturated up to n-3 conjugated isomer.

The conjugated isomers of n-3 and n-3 were found exclusively in polar lipids of liver and plasma while the RA metabolites were found in neutral lipids as demonstrated by Sebedio et al. This shows that conjugated metabolites of cis -9, trans , cis could interfere in the fatty acid composition of membranes which affect their properties such as fluidity and permeability.

Other studies are needed to confirm this hypothesis. This study demonstrated that an equimolar mixture of two CLnA isomers, cis -9, trans , cis and cis -9, trans , cis has the same apparent absorption efficiency than RA when ingested under nutritional and physiological conditions.

Both CLnA isomers are mainly incorporated into neutral lipids. The biological impact of the ingestion of these fatty acids has to be considered as they could interfere with lipid metabolism.

Sherbrooke, Canada. The high oleic sunflower oil and the linseed oil were purchased from Lesieur Asnières, France and Robbe Compiègne, France , respectively. All solvents were purified by distillation before utilization. TAG of CLA and CLnA were synthesized as described by Kodali et al.

The initial weight of the animals was 82 ± 7 g. They were adapted during 4 days with a semi-liquid diet see below before being allocated to one of the 4 dietary groups see below. Six animals were allocated to each group.

The average starting weight in each group was ± 1 g. At the end of the 8 days experimental period, the animals were fasted for 16 hours and weighted.

They were then anesthetised with isofurane and exsanguinated by abdominal aortic blood puncture. The plasma was then collected and stored at °C until lipid extraction and analysis. The experimental diets were fed in a semi-liquid form in order to facilitate the determination of food consumption.

CLA and CLnA were studied as FFA and TAG. The fatty acid content of each diet is summarized in Table 1. Food was exchanged every two days.

At that time, the remaining semi-liquid food was removed and weighed to determine food intake. The animals were weighed twice per times a week. The faeces were collected each day, pooled and frozen at °C.

Before being lyophilized, the total faeces collected from each rat were frozen at °C for 24 h. The dried faeces were cleared of impurities, weighted and crushed with a ball crusher. The extract was then evaporated to dryness and left for one night under vacuum in a dessicator.

The total lipid extract was then weighted and dissolved in chloroform in gauge flask for conservation at °C. The apparent digestion efficiency ADE was calculated as follow [ 22 ]. The quantification of each fatty acid in the faeces was done by GC analysis of their methyl esters using an internal standard Thus, the total fecal lipids were saponified under mild conditions before methylation.

The solutions were left in the dark at room temperature for 16 h. The solution was centrifuged at g for 3 minutes. The resulting FAME were then analysed by GC using a Hewlett-Packard serie II gas chromatograph equipped with a BPX70 capillary column SGE, Melbourne, Australia, m × 0.

FAME were identified using authentic standards and quantitative data were obtained using the Diamir software JMBS Developments, Le Fontanil, France. Liver lipids were separated into phospholipids and neutral lipids as described by Juanéda and Rocquelin [ 23 ]. All lipid classes were methylated with sodium methoxide in methanol 2N.

The resulting FAME were then analysed by gas-liquid chromatography as described above for fecal fatty acids. FAME were identified using authentic standards. RA metabolites were identified as described by Sébédio et al. Qualitative data were obtained using the Diamir software JMBS Developments, Le Fontanil, France.

Data are presented as mean ± SD and comparison were done by using SAS software as a one way FA CLA or CLnA or lipid form FFA or TAG ANOVA procedure. P values of less than 0.

Metrics CLA and nutrient absorption. Absogption linoleic acid CLA is a absorprion CLA and nutrient absorption polyunsaturated fatty nutriwnt which have been HbAc values interpretation studied nnutrient the past two decades. However, Abd octadecatrienoic acid such as cis -9, transcis and cis -9, transcisrecently identified, have not been extensively investigated. This work presents bioavailability and tissue incorporation of a mixture of conjugated octadecatrienoic CLnA acids ingested as free fatty acids FFA and triacylglycerols TAG. Male Wistar rats were fed rumenic acid RA: cis -9, trans and a CLnA mixture cis -9, transcis and cis -9, transcis as FFA and TAG for 8 days. Recent scientific studies have mutrient that CLA reduces body nutrientt while maintaining lean body anc. CLA is a absodption ingredient that works to block the enzyme called lipoprotein which helps Nutdient absorb absorpption into Nnutrient cells. CLA Suppressing appetite naturally this Peppermint oil diffuser and diverts unused fat to muscle cells. CLA then activates enzymes which help your muscles to burn this fat. This increased breakdown of fat helps to prevent fat accumulation in fat cells and helps to fuel and preserve muscle mass. A double-blind trial found that exercising individuals taking 1, mg per day of conjugated linoleic acid CLA lost more body fat after 12 weeks than did a similar group taking a placebo. Green Coffee Bean Extract serves as both a natural, safe weight-loss agent and is a powerful insulin stabilizer and antioxidant.
