This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Obesity is an important health issue, having risen to epidemic proportions in the U.S. Use of conjugated linoleic acid (CLA), positional and geometric isomers of linoleic acid, has received recent attention due to its potential health benefits including the reduction of fat mass in animals. However, the effectiveness and safety of CLA consumption in humans remains unclear. Our group previously reported that trans-10, cis-12 CLA impaired the conversion of preadipocytes into lipid-filled adipocytes (e.g., differentiation) and caused adipocyte delipidation that involved inflammatory cytokines in a human cell model. However, the isomer-specific mechanism for these events was unknown. Thus, this research examined mechanisms by which trans-10, cis-12 CLA induced adipocyte delipidation, inflammation, and insulin resistance in primary cultures of human adipocytes. Delipidation of adipocytes by trans-10, cis-12 CLA was accompanied by increased lipolysis and changes in the morphology of lipid droplets and the expression and localization of proteins regulating lipid droplet metabolism. This process involved the translational control of adipose differentiated related protein (ADRP) through activation of mTOR/p70S6K/S6 signaling and transcriptional control of perilipin A. Prior to these morphological changes, it was shown that trans-10, cis-12 CLA promoted nuclear factor κB (NFκB) and mitogen activated protein kinase (MAPK) activation and subsequent induction of interleukin (IL)-6 which were, at least in part, responsible for trans-10, cis-12 CLA-mediated suppression of peroxisome proliferator activated receptor gamma (PPAR)γ target gene expression and insulin sensitivity in human adipocytes. The essential role of NFκB on CLA-induced inflammation was confirmed by using RNA interference. Further studies were conducted examining the localization and characterization of the inflammatory response, including the type of cells involved, using lipopolysaccharide (LPS) as the inflammatory agent. It was demonstrated that LPS-induced, NFκB-dependent proinflammatory cytokine expression was predominantly from preadipocytes, which led to, at least in part, the suppression of PPAR activity and adipogenic gene expression and insulin sensitivity. Collectively, these data support the emerging concept that adipose tissue is a dynamic endocrine organ with the capacity to generate inflammatory signals that impact glucose and lipid metabolism. Furthermore, human preadipocytes have the capacity to generate these inflammatory signals induced by trans-10, cis-12 CLA and LPS, subsequently causing insulin resistance in neighboring adipocytes. These studies also revealed that NFκB- and MAPK-signaling mediate inflammation and insulin resistance induced by CLA and LPS. Thus, although the trans-10, cis-12 isomer of CLA may decrease the size and lipid content of human adipocytes, it may also cause insulin resistance, which is a hallmark of type 2 diabetes."--Abstract from author supplied metadata.

Available in PDF, EPUB and Kindle. Book excerpt: "Overweight and obesity are the most widespread nutritional diseases in the U.S., which greatly increase chronic disease risks and mortality. Therefore, it is urgent to develop a relatively efficacious and safe strategy for the weight management. Consumption of conjugated linoleic acid (CLA) supplements or one of its isomers, trans-10, cis-12 (10,12) CLA, has consistently demonstrated reductions in body weight or body fat in human and animal studies. Our lab has demonstrated that 10,12 CLA triggered calcium release from endoplasmic reticulum in human primary adipocytes, which activated downstream inflammatory signaling, resulting in impaired uptake of glucose and fatty acid, and delipidation. However, the upstream signals responsible for these actions are unknown. Therefore, my Aim 1 investigated the upstream mechanism by which 10,12 CLA increases intracellular calcium and inflammatory signaling in human primary adipocytes. The results indicated that phospholipase C plays an important role in 10,12 CLA-mediated activation of intracellular calcium accumulation, inflammatory signaling, delipidation, and insulin resistance in human primary adipocytes. It has been demonstrated that 10,12 CLA increased mRNA levels and protein levels of cyclooxygenase-2 (COX-2) and pro-inflammatory prostaglandins, which have been linked to increased energy expenditure associated with white adipose tissue (WAT) browning and uncoupling of ATP synthesis. It also has been shown that relatively high doses of 10,12 CLA lead to more significant reductions in body fat, but cause a greater level of inflammation, insulin resistance, and steatosis in animals. Therefore, Aims 2 and Aim 3 determined the extent to which a relative low dose of 10,12 CLA or a CLA isomer mixture increases markers of browning in mice and its dependence in inflammatory signaling. In Aim 2, a low threshold dose of 10,12 CLA was found that prevented body fat accumulation with minimum metabolic side-effects in non-obese mice. It was also found that 10,12 CLA-induced browning in WAT was accompanied by increases in mRNA levels of COX-2 and other markers of inflammation. In Aim 3, a relatively low dose of 10,12 CLA reduced body fat and increased browning of WAT in overweight mice, which were independent of inflammatory signaling. Collectively, these findings provide critical insights for the development of reliable dietary strategies for people who take CLA as method to lose weight. However, we still do not know (i) if 10,12 CLA supplementation would effectively reduce body fat in overweight mice when they are continuously fed an American-type, high-fat diet; (ii) potential risks of impaired regulation of body temperature, inflammation, and steatosis due to 10,12 CLA consumption in high fat-fed mice; and (iii) potential mechanisms by which 10,12 CLA reduces body fat in high fat-fed mice."--Abstract from author supplied metadata.

This book was released on 2012-06-05 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Functional food or medicinal food is any fresh or processed food claimed to have a health-promoting and/or disease-preventing property beyond the basic nutritional function of supplying nutrients, although there is no consensus on an exact definition of the term. This is an emerging field in food science, in which such foods are usually accompanied by health claims for marketing purposes, such as a company's ‘cereal is a significant source of fiber. Studies have shown that an increased amount of fiber in one's diet can decrease the risk of certain types of cancer in individuals.’ Functional foods are sometimes called nutraceuticals, a portmanteau of nutrition and pharmaceutical, and can include food that has been genetically modified. The general category includes processed food made from functional food ingredients, or fortified with health-promoting additives, like "vitamin-enriched" products, and also fresh foods (e.g., vegetables) that have specific claims attached. Fermented foods with live cultures are often also considered to be functional foods with probiotic benefits."
