The term “dietary fibre” refers to a spectrum of indigestible carbohydrates, mainly of plant origin that have been linked to a range of health benefits. Within plants, algae and fungi, these carbohydrate entities are important structural building blocks, forming the basis of plant cell walls. Isolated dietary fibres are used in a range of different supplements and food formulations. Dietary fibres show diversity in structure, source and physicochemical properties, making it unlikely that all fibres will have equal effects on any given health outcome.
The proposed, desk-based project will incorporate a series of systematic literature reviews in order to compare and contrast the impact of dietary fibre intake, either integral to plant-based foods, or included as an ingredient/supplement, on key markers of cardiovascular health, glycaemic control and body weight. This literature-based approach aims to answer the following key research questions:
• Which fibre types or sources are the most effective in relation to specific health outcomes?
• Is fibre supplementation equivocal to consumption of integral fibre from foods source?
• What gaps in our knowledge of the health effects of dietary fibres exist?
• Are existing dietary guideliness and nutrient, function of health claims related to dietary fibre appropriate?
