Descrição detalhada
The aim of this study is to further strengthen our understanding of the role of dietary components (in particular fibre and protein) in a healthy diet. The information gained from this research will lead to better policy advice, particularly in relation to healthy weight management, metabolic control, mental health and intestinal health. It will also lay the foundations to produce healthier primary products and aid the food industry in developing new and healthier products (e.g. products that aid hunger control and satiety). This will be addressed through four interlinked objectives:
O1: Healthy weight management and improved metabolic and mental health O2: Identification of gut bacteria and compounds of relevance to vascular and gut health O3: Linking fibre consumption to intestinal microbial communities and health O4: Mathematical modelling of interactions between diet and gut microbial communities

Intervenção / Tratamento |
|---|---|

Experimental: High Fibre to High-Protein (HF-HP)
|
High fibre/carbohydrate (50% CHO, 35% fat and 15% Protein) with 45% calories at breakfast and 20% evening meal provided and buffet lunch.
Total dietary fibre will be at least 30g/d for 2000kcal intake and provided as a mixed soluble and insoluble fibre sources to maintain palatability of the diet (e.g.
wheat bran, fava bean, lentil, buckwheat).
Outros nomes:
• High protein diet (30% protein, 35% fat and 35% CHO) with 45% calories at breakfast and 20% evening meal provided and buffet lunch.
Protein will be a mixed meat matrix to include poultry, fish, red meat, prawns, eggs, dairy.
Total dietary fibre will be no more than 15g/d for 2000kcal intake.
