Nutrition in the Prevention and Treatment of Abdominal Obesity by Ronald Ross Watson Pdf
Nutrition in the Prevention and Treatment of Abdominal Obesity focuses on the important roles that exercise, dietary changes, and foods play in promoting as well as reducing visceral fat. Nutritionists, dieticians, and healthcare providers seeking to address the abdominal obesity epidemic will use this comprehensive resource as a tool in their long-term goal of preventing chronic diseases, especially heart, vascular, and diabetic diseases. Experts from a broad range of disciplines are involved in dealing with the consequences of excessive abdominal fat: cardiology, diabetes research, studies of lipids, endocrinology and metabolism, nutrition, obesity, and exercise physiology. They have contributed chapters that define a range of dietary approaches to reducing risk and associated chronic diseases. They begin by defining visceral obesity and its major outcomes; they also discuss the importance and the challenges of dietary approaches to reduce abdominal obesity, as compared to clinical approaches, with major costs and risks. Offers detailed, well-documented reviews outlining the various dietary approaches to visceral obesity with their benefits and failures Includes chapters on types of foods, exercise, and supplements in reducing obesity and its chronic clinical companions, especially diabetes and cardiovascular disease Helps nutritionists, dieticians, and healthcare providers approach patients in making decision about nutritional therapies and clinical treatments for abdominal obesity, from an evidence-based perspective
Arguably the most serious issue facing the food industry is what is now widely recognized as an epidemic in obesity. Food manufacturers are under increasing pressure over both the degree to which they have contributed to the problem and what role they should play in solving it. Drawing on the expertise of some of the world’s leading experts in this area, Food, Diet and Obesity summarizes current research on the causes of obesity, the role of food components in promoting or reducing weight gain, and the strategies manufacturers can adopt to reduce the problem. After an introductory chapter on global trends in obesity, Part 1 looks at the range of contributing factors to obesity, from nutrient-gene interactions, energy metabolism and physical activity to sensory responses to food, portion size and the psychology of overeating. Part 2 looks at macronutrients and their role in weight gain or loss, with chapters on topics such as energy density, dietary fat, carbohydrates, protein and dietary fibre. The final part of the book discusses issues in developing effective strategies for weight control, from gaining consumer acceptance of weight-control food products to the role of community-based approaches in preventing obesity. With its distinguished editor and international team of experts, Food, Diet and Obesity will be a standard work for nutritionists and R&D staff throughout the food industry, as well as all those concerned with understanding and reducing obesity.
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation by Behnam Saremi Pdf
With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through the orchestrated action of hormones. In contrast to the “classical hormones” that knowingly control parturition, lactation and metabolism, the role and importance of messenger molecules originating from body fat (adipokines), of their receptors and also of nuclear receptors as key regulators of gene expression was only scarcely investigated in dairy cows. In particular, data on body fat were largely limited to subcutaneous (s.c.) fat from one location easily accessible via biopsy, whereas potentially heterogeneous reactions between different s.c. depots and also in different visceral (v.c.) fat were not yet comprehensively addressed. The aim of this dissertation was to characterize the mRNA expression of several adipokines and related factors that are involved in insulin sensitivity (IS) and in inflammation during the transition from pregnancy to lactation and during the subsequent lactation. In addition, dietary supplementation with either CLA vs. a control fat (supplementation period day 1 to day 105 or 182 of lactation) was tested for potential effects on the target mRNAs. The tissue in focus was adipose tissue (AT) with its different locations. Initially, suitable reference genes were identified as a methodological prerequisite for the studies. Using tissue samples obtained from both primiparous and pluriparous cows from animal experiments within a project cooperation, the time course of the mRNA abundance of 12 different target genes and 7 reference genes was characterized in s.c. fat and in liver from pluriparous cows and in three different s.c. and in three v.c. fat depots, in liver, skeletal muscle, and in mammary gland from primiparous cows. Two acute phase proteins, i.e. haptoglobin (Hp) and serum amyloid A3 (SAA3), were newly established as adipokines in cattle; both mRNAs yielded similar time course patterns with a peripartal peak. Treatment with CLA was mostly not affecting Hp and SAA3 mRNA expression; the decrease observed for Hp and SAA3 mRNA in 2 out of 6 fat depots tested indicates local anti-inflammatory effects of CLA. No CLA effect was observed for the Hp serum concentrations and for hepatic Hp mRNA. Indeed, we confirmed liver as the main site of Hp production. For the prioritization of nutrient uptake towards the mammary gland, IS in other peripheral organs is knowingly reduced. The mRNA expression of the target genes related with IS, i.e. adiponectin (ADIPOQ), leptin (LEP), their receptors (LEPR, LEPRB, ADIPOR1, ADIPOR2), of two nuclear receptor isoforms (PPARγ, PPARγ2) and of two pro-inflammatory cytokines (TNF-α, IL-6) in s.c.AT and in liver from pluriparous cows was mostly decreased from day 21 prepartum to day 21 postpartum in s.c.AT except TNF-α; in liver increases were observed for LEPRB and ADIPOR2, and decreasing abundance for all other hepatic target mRNAs except TNF-α and ADIPOR1 which remained constant in this time. In later lactation, prepartum values were reached again and were largely maintained until wk 36. The groups treated with CLA or control fat differed detachedly in mRNA abundance of PPARγ, LEPRB and TNF-α in liver and of PPARγ2 in s.c.AT; cows of the CLA group had also higher insulin concentrations and reduced systemic IS persisting after the end of CLA supplementation. In primiparous cows, changes with the duration of lactation were observed for most of the target mRNAs (except LEP) but not in all tissues investigated; time course and direction of change were partly divergent between the different tissues. CLA treatment for 105 days decreased the mRNA abundance of ADIPOQ, ADIPOR2, PPARγ2 and TNF-α in v.c.AT and in the mammary gland. The results of these studies provide a longitudinal characterization of the expression of genes that are particularly related to AT as a heterogeneous functional regulator in lactating dairy cows. The known effect of CLA inhibiting milk fat synthesis might at least be partly explained by the down-regulation of PPARγ2 in the mammary gland observed herein. The importance of the CLA induced effects on IS for animal health can presently not be finally assessed due to lack of validated reference values for IS in high yielding dairy cows.

Effect of Dietary Conjugated Linoleic Acid (CLA) on the Fatty Acid Status in Chicken and Meat Quality by Min Du Pdf
This dissertation includes studies on the effect of dietary CLA on the growth, fat accumulation and fatty acid status of chicken, and chicken meat quality as influenced by irradiation. Results showed that dietary CLA did not have significant effects on the growth rate and feed efficiency in chicken. And high levels of dietary CLA slightly reduced the whole body fat content. High ratio of dietary CLA can incorporate into chicken meat and egg yolk. Dietary CLA reduced the concentration of monounsaturated fatty acids. The concentration of polyunsaturated fatty acids, including arachidonic acid, linolenic acid and linolenic acid, also reduced as the dietary CLA level increased. However, when the dietary level of linolenic acid in diet was high, dietary CLA stimulated the synthesis of DHA and EPA, which might directly relate to the biological effects of CLA. High level of dietary CLA influenced the quality of meat, which was slightly harder and drier compared to the control meat. Dietary CLA significantly improved the oxidative stability of chicken meat. The reason for the improved oxidative and color stability of meat patties during storage should be due to the reduced unsaturated fatty acid content in chicken muscles, which improved lipid and color stability and reduced volatile production in both irradiated and nonirradiated meat during storage. Irradiation greatly increased the volatile production and induced a metal-like off-odor in chicken rolls, and dietary CLA had synergistic effect on this metal-like off-odor. Irradiation also increased the redness of chicken rolls. Consumers had a preference for the color of irradiated chicken rolls, while their reactions to the flavor of irradiated chicken rolls were quite negative.

Metabolic Basis of Obesity by Rexford S. Ahima Pdf
The obesity epidemic has generated immense interest in recent years due to the wide-ranging and significant adverse health and economic consequences that surround the problem. Much attention has been focused on behaviors that lead to obesity, in particular to over consumption of energy-dense food and to sedentary lifestyle. However, obesity is an extremely complex condition with poorly defined pathogenesis. Thanks to greatly enhanced research in the area, the discovery of pathways in the brain and peripheral organs that mediate energy homeostasis has provided a framework for understanding the biological basis of obesity. Metabolic Basis of Obesity adds an important new dimension to the growing literature on obesity by offering a comprehensive review of specifically how metabolic imbalance culminates in obesity. Developed by a team of expert authors, this important title discusses the principles of energy balance, genetics of body weight regulation, hormones and adipokines, and metabolic pathways in the brain, liver, muscle and fat, to name just several of the areas covered. The book also examines the connection between obesity and diabetes, cardiovascular disease and other complications. Current and future diagnostic and treatment strategies are also reviewed. Comprehensive and timely, Metabolic Basis of Obesity is an essential reference for understanding the burgeoning problem of obesity.
