11. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans
Sammanfattning : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. LÄS MER
12. Transglycosylation catalyzed by β-mannanases : Molecular aspects relevant for enzymatic synthesis
Sammanfattning : β-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. LÄS MER
13. Early infant gut flora and neutral oligosaccharides in colostrum in relation to allergy development in children
Sammanfattning : Today, atopic allergy is the most common chronic disease among children in the developed world. The increase in allergy prevalence during the past decades in these countries might be associated with lower microbial exposure. LÄS MER
14. Type l diabetes in childhood and adolescence, environmental exposures and gut microbiota
Sammanfattning : Environmental factors leading to disturbances in the gut microbiota might play an important role as triggers for, and/or contributing factors in, the development of type 1 diabetes (T1D). The overall aim of the research underlying this thesis was to study the influence of environmental factor exposure on the risk of T1D in childhood and adolescence, and gut microbiota composition in early childhood.

15. Nutritional effects of barley products — Mechanisms of action in the intestinal tract
Sammanfattning : Barley is one of the most important crops in the world. Although it is mainly used as the raw material for the production of beer and animal feed, it has recently attracted interest from nutritionists and consumers, due to its high content of dietary fibre, especially β-glucan, and its relation to various positive health effects.
