Development and optimisation of food products low in FODMAPs: an investigation of dietary fibres in low FODMAP products and the reduction of FODMAPs via bio-technological processes
… and appealing food products (e.g., sufficient dietary fibre content and good techno-functional quality) suitable for that diet is very limited. Therefore, this thesis investigated two approaches and their potential for overcoming this challenge. Firstly, three enzymes (invertase, inulinase and …

Novel insights into fibre and lipid substrates on the microbiome
… and function of these symbionts. Identifying dietary components, therefore, that impact this internal community can reveal novel insights into how these symbionts affect and promote human health and well-being. This thesis investigated the effects of dietary fibre and lipid components on the …

Effects of prebiotic fibre diets on rat mucosal intestinal and systemic immunity and in vitro mechanistic analysis of anti-inflammatory effects of lactobacillus strains on rat and human intestinal epithelial cells
… to define the effects of a range of prebiotic dietary fibres on the immune system at the mucosal and systemic level, using Biobreeding rats. L. rhamnosus demonstrated the ability to decrease proinflammatory cytokine and Toll-like receptor agonist-induced IL-8 and CINC-1 production from human …

An in vitro study of the interactions of bacteria from the human colon.
… of bran, cabbage, turnip, carrot and apple dietary fibres. The results suggested that the mixture in which a dietary fibre is supplied influenced its digestibility even though the chemical composition of the different mixtures was very similar. The pentose fractions of the fibre were the …

The impact of dietary components on gut microbiome modulation and health
… This thesis explores the relationships between dietary components, the gut microbiome, and their implications for health, focusing on various dietary fibres, fermented foods, and microbiome interventions. Chapter 1.1 reviews and discusses an overview of the gut microbiome, its role in human …

Immunomodulatory effects of dietary fibre supplementation: effects on cytokine and antibody production and lymphocyte population profiles
… fermentable substrates for gut microflora. Dietary fibre supplementation may provide a strategy for manipulating the intestinal bacterial profile, changing the interaction with the mucosal immune system, thereby modulating the host immune system. We used a BBc rat animal model to evaluate …

Microbiota regulate short chain fatty acids and influence histone acylations in intestinal epithelial cells.
… a vital role in aiding digestion by metabolising dietary fibres. In this process, they produce short chain fatty acids (SCFAs) such as butyrate, an important energy source for intestinal epithelial cells. SCFAs are chemically related to histone acylations, a growing number of post-translational …

The application of metabolomics in human health and disease
… studies.;The study of metabolomic effects of dietary fibres on urinary metabolites from patients with Crohn's disease revealed that each of the 7 dietary fibres did not induce any significant differences in Crohn's disease patients relative to the controls. On the other hand, it was found that …

NUTRITIONAL AND BIOACTIVE COMPOUNDS FROM AGRI-FOOD PRODUCTS AND BY-PRODUCTS: IN VITRO ASSESSMENT OF THEIR POTENTIAL HEALTH EFFECTS
… molecules—such as polyphenols, peptides, and dietary fibres—while mitigating matrix effects that limit extraction efficiency, purity, and bioavailability. The results demonstrated substantial variability in the nutritional composition and bioactive compound content among the studied cultivars, …

Closing the fibre gap in refined cereal product – quality and health
… incorporation of refined and chemically modified dietary fibres (DF) into widely consumed cereal products—pasta, cake, and bread—as a strategy to help close the fibre intake gap. Despite recommendations of 25–38 g/day, actual intake remains low, partly due to the dominance of refined cereals with …

Characterization of dragon fruit (Hylocereus spp.) components with valorization potential
… as vitamins, minerals, complex carbohydrates, dietary fibres and antioxidants. Dragon fruit is also an essential source of betacyanin which serves as a red/purple pigment with antioxidative properties. In Thailand, most of the fresh dragon fruits are consumed domestically, while some are traded …
