Sambandet mellan IBS och FODMAPs

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionABSTRACTTitle: The connection between IBS and FODMAPsAuthor: Helena Hautamäki and Rebecka BertilssonSupervisor: Sofia KlingbergExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-10Background: IBS (Irritable Bowel Syndrome) is a functional gastrointestinal disorder, and is acommon disorder in the western population. The predominant symptoms are diarrhoea,abdominal pain, bloating, constipation, and excessive flatus. Today there are no evidence basedrecommendations concerning dietary factors for patients diagnosed with IBS, but recently certainfactors in the diet that seems to trigger the symptoms have been identified. These factors areshort-chain carbohydrates, Fermentable Oligosaccharides, Disaccharides, Monosaccharides, andPolyols (FODMAPS), which are not completely absorbed in the lumen.Objective: The purpose of this systematic review article is to examine whether there are anyevidence that a diet low in FODMAPs may induce improvement of symptoms in patientsdiagnosed with IBS.Search strategy: The literature search was performed in the databases PubMed, Scopus,Summon and Google Scholar. The keywords were ?Irritable bowel syndrome + FODMAPs?,?Irritable bowel syndrome + diet? and ?FODMAP and diet?.Selection criteria: The inclusion criteria were patients diagnosed with IBS between the ages 18and 69.

Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.

Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation

This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming. The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.

Something fishy in Christians : Dietrekonstruktioner genom analys av stabila isotoper på tidigmedeltida skelett från Rambodal, Styrstad Sn, Östergötland

Dietary patterns has varied throughout history, both due to resource and cultural limitations. In this thesis, a study was conducted to establish the dietary patterns of eight individuals from an early Midieaval gravesite in Rambodal, Östergötland, in order to explain why they were buried there. This was done through stable isotope analysis on collagen extracted from bone and tooth on the buried individuals. The analysis showed that these indviduals had a diet that was mainly based on freshwater fish. This suggests that these people may have been christians, due to the fact that fish was not regarded as meat and therefore you did not have to abstain from it during periods of fasting.

Bakomliggande orsaker till användandet av kosttillskott : En enkätstudie om användning och attityder till kosttillskott

Several studies shows that dietary supplements do not have any proven effects on health, yet these supplements are increasing in sales. The study aims to find out what attitudes and knowledge people involved in physical activity have towards supplements and which factors influence them to buy supplements. How these factors differ between men and women was investigated. The study is based on answers from 100 collected questionnaires from people who are physically active at several gyms. Of those who participated in the study, 56 percent were men and 44 percent were women.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Dairy fat biomarkers and cardiometabolic health

Commonly held dietary guidelines discourage full-fat dairy consumption due its to high levels of saturated fatty acids, which are believed to aversely influence cardiovascular disease risk. Cardiovascular diseases cause more than one third of deaths in the developed world. With dairy often providing a large part of energy and nutrients in Western diets, research into its effects on human health is warranted. Several recent studies have suggested a protective role of dairy in the development of cardiometabolic disease. However, many of these have used imprecise methods of dietary assessment, based on questionnaires or interviews. Biomarkers are emerging as a means of evaluating diet in a more objective way. Currently used dairy fat biomarkers are minor fatty acid constituents of dairy that preferably are unique to dairy and not influenced by endogenous metabolism.

Kyrkotillhörighet och diet i det medeltida Visby : Diet och social status utifrån isotopanalyser av gravlagda från tre Visbykyrkor

This paper deals with three mediaeval churches in the town Visby, Gotland. These churches were located in different areas in Visby. Allegedly the areas where St Hans and Ste Gertrud were located were inhabited by wealthier people, and the more peripheral area where St Mikael was located was where the poor lived. Therefore, the people that were buried at St Mikael should be of lower social status than the people buried at St Hans and Ste Gertrud. Based on the fact that an individuals diet was dependant on his or hers social status, dietary studies on skeletal remains from the three different churches have been conducted to find out dietary patterns among the individuals buried at each church respectively.

Kan Olikheter ena? En studie om sociala rörelsers potential att skapa dialog

In the process of globalization, identity has become one of the central factors.An understanding of the difference that makes up our society has made thequestion of weather is it possible to envision a society where difference is thecommon ground, one that has been up for contest. To answer this we need to seeif this kind of democracy is possible at all. For this I?m turning to the socialmovments who while they are working close to the reality also can give us somereal answers. Therefore I have looked at how social movements adress identity,difference and conflict and concluded that three things are crucial in organizing ongrounds of difference.

Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Anställningsformers betydelse för häla

The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.

This essay examines if there is any difference how the two biggest tabloids in Sweden, Aftonbladet and Expressen is portraying the Swedish national football team for both woman and men. The purpose is to compare and see if there is any difference regarding what gender you have. We have also examined what gender the authors for the articles have. We have used a quantitative content analysis to get our results. In conclusion, there is a big difference in medial space regarding what gender you have.

Review of the litterature and an attempt to evaluate intake levels of iodine and selenium in dogs with and without lymphocytic thyroiditis

The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.

Alumner från SLU, Skogsmästarskolan säger sitt

The purpose of this study is to investigate the forest managers view of the edu-cation at the School for Forest management at SLU and the first years of em-ployment. Surveys were sent to batches 05/08, 06/09 and 07/10 a total of 136 question-naires were sent out. 80 people answered the survey, this gives a response rate of 59 percent The former students rated according to a 9-grade scale how satisfied they were with the different courses they had attended during their years as students at the school. The courses in mathematics and statistics got the highest marks with an average of 7.3, while the entry-level course in law only got an average of 4.6. A major part of the former students had in the questionnaire enquired a leader-ship course and a business course with focus on negotiation techniques during their education. There is a wide variety of employment opportunities for the graduated students. Timber buyers and forest managers or planners are just a few positions that for-mer students now possess. The study shows that there is a big difference in the first introduction to a new work place depending on where the student got hired.

Eurolution : Har internhandeln i euroområdet ökat sedan euron infördes?

Denna undersökning ämnar utreda huruvida euroinförandet år 2002 medfört ökad internhandel i EMU. Undersökningen analyserar handelsstatistik från år 1998- 2008 för de femton länderna som vid euroinförandet var medlemmar i EU. I analysen studeras två grupper av länder; en innehållande EMU- länder och en kontrollgrupp innehållande länder som inte infört euron. För att kontrollera för underliggande faktorer som exempelvis konjunkturella förändringar och preexisterande handelsskillnader genomförs två difference- in- difference analyser. Undersökningen finner inget statistisk signifikant resultat på en ökad internhandel i EMU efter euroinförandet.
