Fibre - Need to increase intake according to new recommendations

"Wait, Do I Need More Fiber?" Exploring UK Consumers' Dietary Fiber-Related Awareness and White Bread as a Viable Solution to Promote Subsequent Intake

Background

Sufficient dietary fiber consumption is associated with well-established health benefits, yet such intake is currently suboptimal globally. Thus, there is interest in developing strategies to improve dietary fiber intake. One such approach is to increase the dietary fiber content of staple foods, but this needs relevant investigation.

Methods

Forty-two United Kingdom (UK) based consumers (18-76 y) were recruited to take part in seven focus group sessions investigating: (i) key factors in food choice; (ii) dietary fiber-related knowledge, awareness, consumption habits, and engagement levels; (iii) willingness to consume dietary fiber-rich staple foods; and (iv) gain initial feedback on dietary fiber-rich breads.

Results

Overall, key dietary fiber themes emerged such as knowledge (benefits, foods, recommendations and labeling), consumption (not measuring intake), barriers (convenience and knowledge), resources (education and public appeal), and topics (food examples and cooking). Consumers were positive per se to the idea of dietary fiber-rich staple foods but with various caveats (no changes in appearance, taste, and cost). White bread trends were centered around context (sandwich and toast), habit (comfort food), preferences (soft and fresh), and consumption is variable (daily to less often). In addition, consumers' preferred labeling strategy for dietary fiber-rich breads was predominately focused on transparency and visibility. Overall, the newly developed breads were well received demonstrating the potential of our prototypes to fit into the white bread market; however, additional consumer insights are needed.

Conclusion

Our findings recommend combining education with a personalized element of advice, coupled with a collective effort from the government and food industry, as essential to help encourage a step-change in dietary fiber consumption in the UK population.

Fibre4life: Investigating older adults dietary fibre preferences and the role of targeted educational materials on modulating future dietary fibre intake

The UK has an ever-increasing ageing population; hence, promoting balanced nutrition can have fundamental health and cost benefits. In addition, the majority of older adults' dietary fibre intake is below recommendations and this is despite its well-cited benefits; therefore, more emphasis should be placed on identifying viable age-suitable strategies to overcome the associated dietary fibre-related knowledge gap. Accordingly, one hundred and seventy older adults (65-87 years) were recruited to partake in two survey related studies: (1) initial insights (e.g., dietary fibre-related knowledge, awareness, attitudes and behaviour as well as information preferences) were captured to inform the design of educational materials; and (2) the impact of two targeted educational materials on modulating older adults' future dietary fibre intake was tested. Older adults were willing to learn more about dietary fibre and requested additional information relating to its benefits, recommendations and food-based examples in a clear and accessible format. Therefore, two educational materials (factsheet and practical tips) were developed encompassing key themes. Overall, older adults engaged with the educational materials (regardless of topic and format); thus, demonstrating the potential benefits of this approach going forwards. There was strong agreement with all variables: learning something new, change future dietary fibre intake, format liking, content engaging and share with others as well as the overall experience being cited as useful/helpful. Going forwards, importance should be placed on measuring dietary fibre consumption post engaging with educational materials. In addition, utilising a holistic approach incorporating support from different sources (e.g., health professionals, government, food companies, supermarkets and community) could be fundamental in helping older adults to consume more dietary fibre and subsequently contributing to positive health outcomes.

The ultra-processed foods hypothesis: a product processed well beyond the basic ingredients in the package

The NOVA classification of food items has become increasingly popular and is being used in several observational studies as well as in nutritional guidelines and recommendations. We propose that there is a need for this classification and its use in the formulation of public health policies to be critically discussed and re-appraised. The terms 'processing' and 'ultra-processing', which are crucial to the NOVA classification, are ill-defined, as no scientific, measurable or precise reference parameters exist for them. Likewise, the theoretical grounds of the NOVA classification are unclear and inaccurate. Overall, the NOVA classification conflicts with the classic, evidence-based evaluation of foods based on composition and portion size because NOVA postulates that the food itself (or how much of it is eaten) is unimportant, but rather that dietary effects are due to how the food is produced. We contend that the NOVA system suffers from a lack of biological plausibility so the assertion that ultra-processed foods are intrinsically unhealthful is largely unproven, and needs further examination and elaboration.
