This book was released on 2005 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Conjugated linoleic acid (CLA) refers to a class of positional and geometric isomers of octadecadienoic acid (C18:2) with conjugated double bonds found primarily in milk and meat products from ruminant animals. Several studies have shown that dietary intake of CLA can have positive health benefits, including antiadipogenic, antidiabetogenic, anticarcinogenic, and antiatherosclerotic properties and other desirable effects on bone growth, lipid metabolism and gene expression. Hampshire x Dorset lambs (n = 46) were used for this project. Hampshire x Dorset Iambs (n = 46) originating from the OARDC flock in Wooster, OH were used for this project. The supplementation of oil in the Iambs' diets was evaluated during two different stages of growth. The first stage was the pre-weaning, which in this study refers to the time the lamb is born through weaning including the transition period (time from weaning until lambs were allotted to a finishing pen). The second stage was from the time the lamb was allotted to a finishing pen until it reached the targeted endpoint and was harvested. Pre-weaning oil supplementation consisted of 2% soybean oil and 1% marine algal oil, and post-weaning oil supplementation consisted of 2% soybean oil and 1% linseed oil. Additionally, the effects of dietary oil supplementation to lambs on the retail case life of fresh lamb, and the stability of CLA in two processed, value-added meat products was determined. Supplementing ewes with PUFA while they are nursing lambs did not result in increased CLA levels in the muscle or subcutaneous fat of the lambs when they were harvested. Additionally, supplementing the lambs with PUFA during the growing and finishing phases (post-weaning) did not increase CLA content of the muscle or subcutaneous fat. There were trends for wethers to have more cis9 trans 11 CLA and total CLA in longissimus dorsi, and ewe lambs had significantly more trans10 cis12 CLA in subcutaneous fat, but all of these differences were small and may not play an important role in the nutritional benefits of consuming lamb products. Increasing PUFA in the diets did not result in negative effects on retail case life of fresh lamb. Conjugated linoleic acid content was stable in muscle tissue during mechanical and thermal processing techniques applied to value-added, further processed meat products.

Book Synopsis Exogenous Effects of Alpha-linolenic and Linoleic Acid on the Fatty Acid Distribution and the Regulation of Lipid Metabolism in Ruminant Tissues by : Andrea Herdmann
Download or read book Exogenous Effects of Alpha-linolenic and Linoleic Acid on the Fatty Acid Distribution and the Regulation of Lipid Metabolism in Ruminant Tissues written by Andrea Herdmann and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is concerned with the exogenous effects of alpha-linolenic (ALA) and linoleic acid (LA) on the fatty acid distribution and the regulation of lipid metabolism in ruminant tissues. Two animal experiments were conducted to investigate the effect of diets enriched in ALA or LA in German Simmental and Holstein bulls. The influence of LA and ALA enriched diets on the protein expression of lipogenic enzymes in cattle, the tissue specific differences and the relationship between protein expression of lipogenic enzymes, enzyme activities and the products of these enzymes as well as the absorption and deposition of n-3 and n-6 fatty acids in ruminants and beef products was analyzed. Feeding a diet enriched in LA or ALA results in an increased deposition of these fatty acids, induced chain elongation, desaturation and deposition of the long-chain products in tissues of ruminants. Essential fatty acids are preferentially deposited in longissimus muscle (MLD) compared to subcutaneous adipose tissue (SAT) and also preferred in erythrocytes; conclusively they are good long-time marker for the fatty acid intake. Despite the low proportion of de novo fatty acid synthesis in the liver of ruminants the concentration of n-3 fatty acids and de novo synthesised n-3 long chain polyunsaturated fatty acids is much higher compared to MLD. ...
Book Synopsis Effect of Omega-3 Fatty Acids on T10, C12-conjugated Linoleic Acid Induced Insulin Resistance, Non Alcoholic Fatty Liver Disease and Tissue Fatty Acid Composition by : Madhuri Vemuri
Download or read book Effect of Omega-3 Fatty Acids on T10, C12-conjugated Linoleic Acid Induced Insulin Resistance, Non Alcoholic Fatty Liver Disease and Tissue Fatty Acid Composition written by Madhuri Vemuri and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated linoleic acid (CLA) refers to all the positional and geometric isomers of linoleic acid. The two most studied isomers are cis9, trans11-CLA and trans10, cis12-CLA. CLA supplements, often a mixture of the two isomers, have been popularly used for weight loss and other claimed health benefits. However supplementing CLA isomers, especially trans10, cis12-CLA has been shown to cause non alcoholic fatty liver disease (NAFLD) and insulin resistance (IR) in several animal models. Here we have confirmed that supplementing 0.5% trans10, cis12-CLA to C57BL/6 mice for 8 weeks causes NAFLD and IR. When CLA diets were concomitantly supplemented with omega-3 fatty acids docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA) at 1.5% (w/w) for 8 weeks, DHA prevented CLA induced IR, while EPA was ineffective. Both EPA and DHA prevented CLA induced fatty liver. CLA also reduced the plasma leptin and adiponectin concentrations, and both EPA and DHA partially restored plasma leptin, but only DHA partially restored the plasma adiponectin. In another experiment, concomitant supplementation of CLA diets with 0.5% of flaxseed oil (rich in alpha linolenic acid) also prevented IR and decreased liver weights and lipids compared with those in CLA group. CLA supplementation also altered lipid profile in liver, decreasing n-6 and n-3 wt% and increasing n-6:n-3 ratio. Concomitant supplementation with flaxseed oil increased n-6 and n-3 polyunsaturated (PUFA) in liver lipids and decreased the n-6:n-3 ratio compared to that in CLA group. Supplementing 0.5% (w/w) of purified c9, t11- or trans10, cis12-CLA to mice for 8 weeks altered fatty acid profile of tissues differently. c9, t11-CLA diet reduced MUFA wt% in liver, adipose tissue, and spleen, and reduced the spleen n-3 PUFAs significantly while increasing the n-6 PUFA wt% in all tissues except heart. In contrast, trans10, cis12-CLA reduced both the n-6 and n-3 PUFA wt% in liver and heart however increased the wt% of n-3 PUFAs in spleen. Considering the adverse health effects of trans10, cis12-CLA and of mixtures of CLA isomers on NAFLD, IR and tissue fatty acids, human use of CLA supplements should not be recommended.
Book Synopsis Effects of Dietary Linoleic Acid on Conversion of Omega-3 Fatty Acids to Long Chain Fatty Acids by : Elizabeth Flaherty
Download or read book Effects of Dietary Linoleic Acid on Conversion of Omega-3 Fatty Acids to Long Chain Fatty Acids written by Elizabeth Flaherty and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the modern diet that is high in total fats, high in omega-6 fatty acids (FA), and low in omega-3 FA, there is a high prevalence of metabolic and cardiovascular disease. Certain dietary acids are beneficial, while others may contribute to these disease processes. Eggs are an important part of the human diet as they are protein and nutrient dense and are a good source of vitamins and minerals. It is possible to manipulate the nutrients and composition of FA in the eggs by modifying the balance of the hens diets. This makes them a good target for experiments with fatty acids (FA). A diet high in omega-3 (n-3) FA has many beneficial effects including plasma lipid reduction, reduction in some types of cancer mortality, anti-inflammatory effects, antiarrhythmic effects, antithrombotic effects, antiatheromatous effects, and less severe manifestations of autoimmune diseases and inflammatory diseases. Due to the benefits of n-3 FA, it is important to understand the effects of oleic acid and linoleic acid (LA; C18:2n-6) on the deposition of n-3 FA in egg yolks. The goals of the experiment are to determine the effect of these FA on deposition of ALA and VLC n-3 FA in yolks. It is hypothesized that LA will have a negative impact on the deposition of ALA in yolks as they compete for elongase and desaturase enzymes. Additionally, it is expected that oleic acid will also have a negative effect on n-3 deposition in yolks.Fifty hens were randomly assigned to one of five dietary treatments that included a control, two levels of high oleic safflower oil (HOSO; 2% and 4%), and two levels of high linoleic safflower oil (HLSO; 2% or 4%). All diets contained 4% flaxseed oil (FLAX) to provide -linolenic acid (ALA; C18:3n-3) as a substrate for synthesis of the very long chain omega-3(VLC n-3) FA. Egg samples were collected on day 0 and day 28 of the experiment and were analyzed for yolk weights and FA composition. Samples of adipose and liver tissue were collected on day 28 for FA analysis.Increasing dietary oleic acid (18:1n-9), provided by HOSO, had a positive effect on deposition of oleic acid in the yolk. Increased dietary linoleic acid (LA; C18:3n-6), provided by HLSO, had a negative effect on oleic acid deposition. HOSO and HLSO also negatively affected the deposition of ALA and VLC n-3 FA in yolks. This supports previous experiments that showed dietary n-6 FA had a negative effect on deposition of n-3 FA in yolks as a result of competition for the elongase and desaturase enzymes. The diet that is most conducive to developing a high n-3 fatty acid egg is a diet with a high level of ALA and a low level of oleic and linoleic acid.

Book Synopsis Update on Trans Fatty Acids and Health by : Great Britain. Scientific Advisory Committee on Nutrition
Download or read book Update on Trans Fatty Acids and Health written by Great Britain. Scientific Advisory Committee on Nutrition and published by Stationery Office Books (TSO). This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current guideline for the consumption of trans fatty acids (trans FA) is that they should not exceed 2% of food energy. Due to health concerns, the Food Standards Agency was asked to consider the case for a reduction in this recommendation to less than 1% and the Scientific Advisory Committee on Nutrition has thus tasked with examining recent scientific evidence on the health effects of trans FA. It concludes that there is consistent evidence to support a moderate effect of trans FA on increasing the risk of coronary heart disease but evidence related to other diseases is limited and no reliable risk assessment can be made. There is however no firm scientific basis for a change in the current recommendation of not exceeding 2% of food energy. There is also insufficient evidence to justify the differentiation of trans FA from vegetable oil and animal sources.
