The development of metagenomic analysis for gut microbiota and systematic bile-acid measurement using LC–MS/MS has triggered a breakthrough for research in this field. Clinically, an inhibitor of the ileal bile-acid transporter (Elobixibat) was used as a therapeutic agent for chronic constipation, which also paved the way for progress in bile-acid signal research. Additionally, this review emphasizes the importance of gut microbiota-bile acid-receptor signals when considering nutritional approaches to promote healthy longevity.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130362426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In obesity and diabetes, insulin resistance is induced via various mechanisms, and among them is endoplasmic reticulum (ER) stress. We recently reported that eating induces transient ER stress and consequent ER stress response in the liver. During eating, expression of Sdf2l1, an ER-resident molecule involved in ER stress-associated degradation, is induced as a part of ER stress response. XBP-1s regulates expression of Sdf2l1 at the transcription level, and Sdf2l1 terminates eating-induced ER stress in the liver, consequently regulating glucose and lipid metabolism. In obesity and diabetes, however, ER stress response is impaired, partly because insulin-mediated translocation of XBP-1s to the nucleus is suppressed, which results in further excessive ER stress. Induction of Sdf2l1 by XBP-1s is highly down-regulated, but restoration of Sdf2l1 ameliorates glucose intolerance and fatty liver. In diabetic patients, hepatic insulin resistance induces enhanced ER stress and ER stress response failure in the liver, which in turn promote hepatic fibrosis and contribute to the development of steatohepatitis comorbid with diabetes.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123231948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a medical problem that increases the risk of other diseases, such as heart disease, diabetes, high blood pressure and certain cancers. Although there are genetic, behavioral, metabolic and hormonal influences on body weight, obesity occurs when you take in more calories than you burn through exercise and daily activities that is when energy intake exceeds energy expenditure. Diet plays an important role in the pathogenesis of obesity; fatty foods are energy dense and gives 9calories per gram compared to carbohydrate and protein that gives 4calories per gram. Also, if physical activity is inadequate, excess consumption of fat can results into weight gain. It does not take as much energy (about 3%), to convert and store dietary fat as it does to convert and store glucose. Fats are easily stored by the body. The aim of this chapter is to provide an understanding of physiological causes and effects of obesity as this will help to promote positive food choices. It is probable that an understanding of dietary patterns and how it relates to obesity will go a long way in the treatment of this complex problem.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127622758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, glucose is needed for many brain functions such as memory and emotion among others. Glucose induces the secretion of insulin, which is needed for transportation of tryptophan from the blood to the brain. Serotonin, which is converted from tryptophan, is important for mood stability, control of emotion, and feeding is inhibited by serotonin in the hypothalamus. We discuss transportation of glucose from the blood to the glia cells. After glycolysis of glucose in the glia lactic acid is transported to cells such as glutaminergic neurons. After the release from neurons glutamic acid is taken up into glia cells and further to neurons again. Sucrose is degraded into glucose and fructose in the intestine thus intake of sucrose increases plasma levels of glucose. We show that intake of sucrose enhanced memory measured by Morris maze in rats and improved the working ability in humans. Roles of glucose and sucrose intakes are discussed together with the function of serotonin in feeding.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"430 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113998541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Psychotherapy can promote behavioral change that improves medication adherence, dietary choices, exercise, stress, and other variables that affect blood sugar levels. The current chapter summarizes the trends in recent research for psychotherapeutic interventions for the management of T2DM. The results from 16 randomized controlled trials on cognitive-behavioral therapy, motivational interviewing, counseling, and mindfulness-based therapies are discussed. These interventions varied in length (3 to 18 months) and were conducted in many geographic regions (e.g., Australia, Netherlands, Saudi Arabia, Thailand, and more). Changes in biological health outcomes (i.e., HbA1c levels) were the primary focus of this chapter, but diabetes-related behavioral changes (e.g., diet and exercise) and psychological variables (e.g., stress, depression, and well-being) are also discussed.

Kanno","doi":"10.5772/INTECHOPEN.98904","DOIUrl":"https://doi.org/10.5772/INTECHOPEN.98904","url":null,"abstract":"Although Na+ homeostasis in vivo is essential for mammals, it is known that excessive salt (NaCl) intake has played a major role in the development of hypertension. In vivo, there is a hormonal system, the renin-angiotensin-aldosterone system (RAAS), that specializes in regulating Na+ retention, especially the amount of Na+ in plasma. Na+ homeostasis in vivo has been achieved mainly by the RAAS, through regulation of vascular tonus (blood pressure) and Na+ handling in the kidney (Na+ diuresis). Recent studies have revealed a third mechanism of Na+ homeostasis in vivo: regulation of interstitial Na+ levels in tissues, such as subcutaneous tissues, by tissue macrophage immunity. In the pathogenesis of salt-sensitive hypertension, Recent research have been revealed that three molecular axes (Ang II - Rho/NOX-eNOS system, Aldosterone-rac1 -ENaC system, and tissue Na+ − TonEBP in macrophage -VEGF-c) are significantly involved in maintaining Na+ homeostasis in salt induced hypertension. Furthermore, the mechanism by which salt causes hypertension via the immune system (intestinal, local mucosal, and tissue immunity) has also been reported. In this article, we would like to propose that three molecular dysfunctions are involved in the development of salt-sensitive hypertension through three immunological mechanisms in the maintenance of Na+ homeostasis. Next, I would like to explain the importance of gut-RAAS and abnormality of intestinal microflora (dysbiosis) in salt-sensitive hypertension. It has been known that the metabolites (e.g., short-chain fatty acid neural amino) produced by microflora are deeply involved in central (CNS) and sympathetic nervous system (SNS) activity. In addition, we would like to explain of the importance of brain-RAAS and cerebral inflammation in salt-sensitive hypertension. Moreover, recent research have revealed that the detection-mechanism in the brain for Na+ concentration([Na+]) in vivo and in the tongue for [Na+] in diet. These finding suggests that excessive salt intake may cause brain dysfunction, most delicate organ, before the onset of salt sensitive hypertension, and may also destroy brain structure after the onset of salt sensitive hypertension. Thus, we would like to insist that excessive salt intake might not only induce hypertension, but also be toxic especially for brain. Finally, we would like to explain that The DASH diet (Dietary Approaches to Stop Hypertension) is one of the universal diets for adult human, not only by reducing salt, but also by reducing metabolic stress and improving of dysbiosis.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114071342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies in rats have shown that the odors of grapefruit and Osmanthus fragrans (OSM, fragrant tea olive) attenuate food intake, leading to a reduction in body weight gain, but it is not yet clear whether the causative mechanisms underlying these effects are the same for both odors. The first part of the present study revealed that grapefruit odor had no effect on the expression of feeding-related neuropeptides, in contrast to the previous finding that OSM odor suppresses orexigenic and activates anorexigenic neuropeptides in the hypothalamus of the rat. The second part revealed that OSM odor activated the parasympathetic nerve, in contrast to the previous finding demonstrating that grapefruit odor activates sympathetic nerve activity. The third part was performed to confirm the previous findings about the effects of OSM odor on appetitive reactions in humans. In human subjects, we found that continuous exposure to OSM odor attenuated appetite and consumption of snacks (cookies) and improved mood, when evaluated using the POMS (Profile of Mood States) data from university students. In conclusion, OSM odor attenuated appetite and decreased food intake in humans, and the underlying causative mechanisms differed from those mediating the effects of grapefruit odor, specifically in terms of the expression of hypothalamic feeding-related neuropeptides and autonomic nerve activity.","PeriodicalId":310007,"journal":{"name":"Psychology and Patho-physiological Outcomes of Eating [Working Title]","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126480360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This unique anatomical location allows astroglia to play pivotal roles in brain metabolism as well as in the regulation of cerebral blood flow. In particular, astroglial cellular metabolic compartmentation exerts supportive roles in dedicating neurons to the generation of action potentials and protects neurons against the oxidative stress associated with their high energy consumption. Key products of astroglia include lactate and ketone bodies (beta-hydroxybutyrate and acetoacetate), which can also be produced avidly by muscle and liver, respectively. Therefore, brain cells, skeletal muscles, and hepatocytes constitute a metabolic compartmentation in the whole body. In this chapter, I will focus on brain cells, especially astroglia, since the impairment of normal astroglial function can lead to numerous neurological disorders including stroke, neurodegenerative diseases, and neuro-immunological diseases.
