A comprehensive review highlights the urgent need to increase dietary fiber intake in the UK through policy, food reformulation, and public education to combat chronic diseases and improve public health.

Britain faces a significant nutritional challenge, with adults consuming only about 18 grams of dietary fiber daily—well below the advised 30 grams. This insufficiency is linked to increased risks of heart disease, type 2 diabetes, and colorectal cancer, posing serious public health concerns. A recent comprehensive review led by the University of Reading, published in a special edition of Philosophical Transactions of the Royal Society B, underscores the urgency of increasing fiber intake across all age groups in the UK.

The study highlights that children consume 3 to 9 grams less than the recommended daily intake, while adults face a deficit of 12 to 14 grams. To bridge this gap, the researchers emphasize a multifaceted approach involving policymakers, food producers, and consumers. Strategies such as improved food labeling with clear fiber content indicators, public education campaigns to correct misconceptions, and reformulation of staple foods to contain higher fiber levels are crucial.

For example, cereal-based products provide the largest share of dietary fiber (41%), followed by vegetables and potatoes (28%). Pulses, including baked beans, are notable fiber sources but are only eaten by about a third of the population. Interestingly, despite white bread being low in fiber, over 83% of households purchase it daily, making it a significant contributor to total fiber intake.

Innovative initiatives in the UK, like the University of Reading's 'Raising the Pulse' project—blending wheat flour with pulse-based nutrient-rich flours—and the 'Hi-Fi Bread' project, which develops high-fiber wheat strains through traditional breeding, exemplify potential solutions. The review stresses the importance of systemic change, involving food system actors from farmers to policymakers, to ensure the sustainable, affordable, and appealing availability of fiber-rich foods.

Key recommended actions include implementing front-of-pack traffic light labeling for fiber, increasing educational efforts to raise awareness of the 30g daily target, reformulating foods to boost fiber content, developing high-fiber wheat varieties, and establishing policies similar to Denmark's Wholegrain Partnership.

Achieving these goals necessitates a coordinated effort to transform the UK food system, encouraging healthier diets and reducing the risk of chronic diseases related to low fiber consumption.
