The Role of Fiber in Health and Nutrition
Dietary fiber is an essential component of a healthy diet and plays an important role in supporting digestive, metabolic, and overall health. Found naturally in plant-based foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds, fiber contributes to gut function and interacts with the gut microbiota in ways that influence multiple aspects of health.
Despite its recognised benefits, fiber intake remains below recommended levels. The following educational resources explore the science of dietary fiber, its mechanisms of action, and practical approaches to increasing fiber intake, helping you better understand its role in health promotion and disease prevention.

Highlighting the widespread fibre gap across Europe, this infographic provides an overview of current fiber intakes, major dietary sources of fiber, and the evidence linking higher fiber consumption with improved health outcomes. It explores the physiological mechanisms through which fiber supports gut health, cardiometabolic health, and disease prevention, while emphasising the role of plant-based dietary patterns in helping populations meet recommended fiber intakes.

Focusing on the practical application of nutrition science, this toolkit addresses common barriers to increasing fiber intake, including gastrointestinal concerns, cost, and food preferences. It provides realistic food swaps, meal ideas, and examples of dietary patterns that can help individuals achieve recommended fibre intakes, translating evidence-based guidance into practical everyday strategies.
Exploring the science behind different types of dietary fiber, this infographic examines how fiber structure and physicochemical properties influence physiological effects throughout the gastrointestinal tract. It explains key mechanisms including fermentation, short-chain fatty acid production, microbiota modulation, satiety, and nutrient absorption, while summarising evidence linking fiber intake with reduced risk of obesity, type 2 diabetes, and cardiovascular disease. The resource highlights the importance of fiber diversity and the contribution of a wide variety of fiber-rich plant foods to health.
