Exploring UK Consumers' Dietary Fiber-Related Awareness and White Bread as a Viable Solution to Promote Subsequent Intake. Curr Dev Nutr 2024; 8:104430. [PMID: 39279786 PMCID: PMC11401220 DOI: 10.1016/j.cdnut.2024.104430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Revised: 07/05/2024] [Accepted: 07/22/2024] [Indexed: 09/18/2024] Open
Abstract
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.

Increasing fibre intake in the UK: lessons from the Danish Whole Grain Partnership. Br J Nutr 2024; 131:672-685. [PMID: 37737071 PMCID: PMC10803819 DOI: 10.1017/s0007114523002106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 08/16/2023] [Accepted: 09/18/2023] [Indexed: 09/23/2023]
Abstract
Diets deficient in fibre are reported globally. The associated health risks of insufficient dietary fibre are sufficiently grave to necessitate large-scale interventions to increase population intake levels. The Danish Whole Grain Partnership (DWP) is a public-private enterprise model that successfully augmented whole-grain intake in the Danish population. The potential transferability of the DWP model to Slovenia, Romania and Bosnia-Herzegovina has recently been explored. Here, we outline the feasibility of adopting the approach in the UK. Drawing on the collaborative experience of DWP partners, academics from the Healthy Soil, Healthy Food, Healthy People (H3) project and food industry representatives (Food and Drink Federation), this article examines the transferability of the DWP approach to increase whole grain and/or fibre intake in the UK. Specific consideration is given to the UK's political, regulatory and socio-economic context. We note key political, regulatory, social and cultural challenges to transferring the success of DWP to the UK, highlighting the particular challenge of increasing fibre consumption among low socio-economic status groups - which were also most resistant to interventions in Denmark. Wholesale transfer of the DWP model to the UK is considered unlikely given the absence of the key 'success factors' present in Denmark. However, the DWP provides a template against which a UK-centric approach can be developed. In the absence of a clear regulatory context for whole grain in the UK, fibre should be prioritised and public-private partnerships supported to increase the availability and acceptability of fibre-rich foods.

Fibre4life: Investigating older adults dietary fibre preferences and the role of targeted educational materials on modulating future dietary fibre intake. Appetite 2024; 192:107109. [PMID: 37914038 DOI: 10.1016/j.appet.2023.107109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 10/17/2023] [Accepted: 10/29/2023] [Indexed: 11/03/2023]
Abstract
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.

Abstract
OBJECTIVE To explore whole-grain food definitions in labeling and relevance to consumers and the food industry. DESIGN Semistructured focus groups and interviews. SETTING Online. PARTICIPANTS Consumers (n = 43) aged ≥ 18 years currently purchasing/consuming grain foods. Food industry participants (n = 17) currently/recently employed within grain food companies. PHENOMENON OF INTEREST Impact of using whole-grain food definitions in labeling. ANALYSIS Inductive thematic analysis. RESULTS Six major themes included: consumer knowledge and understanding of whole-grain foods; factors affecting consumer grain food choices; consumer skepticism of labeling; consumer preferences toward whole-grain labeling; acceptability and feasibility of whole-grain food definitions in the food industry; and food innovation/reformulation. For the food industry, definitions impact feasibility, food innovation, and reformulation. Skepticism affected consumer knowledge and understanding, impacting grain food choice and their preference regarding whole-grain labeling. Consumers preferred whole grain in the name of a food and placing the percent of whole grain on the front-of-pack. CONCLUSIONS AND IMPLICATIONS Our findings suggest that definitions and regulations, consumer education, and strategies addressing factors influencing consumer choice are needed to improve population whole-grain intakes. Future research may consider formal regulation and implementation of standardized whole-grain food definitions in labeling and explore the subsequent impact on consumer choice and whole-grain intake.

Abstract
Background: Unhealthy diets are typical of university students and are often thought to be unrepresentative of the general population. The main aim was to determine the energy and nutrient intakes of a large cohort of undergraduate university students; and to compare to gender-specific dietary reference values (DRVs) and nutrient data from the general population. Methodology: Data was collected from 639 university students aged 18-24 years who completed 4-day diet diaries. The energy and nutrient intake was determined and percentage energy values calculated and compared with dietary reference values (DRVs) and the National Diet and Nutrition Survey (NDNS) and Family Food Statistics. Logistic regression methods were used to identify micronutrients functioning as predictors of exceeding DRVs. Results: Energy intakes were lower than the DRV. The percentage total energy values for protein, fat, saturated fat and carbohydrate exceeded DRVs but the percentage energy from alcohol was below the maximum 5%. The DRVs were met for vitamin C, thiamin, and sodium/salt. Iron and calcium intakes were met in males but not in females. Intakes for fibre and vitamin A were below the DRV. Student data was comparable to the NDNS, with the exception of alcohol, fibre, vitamin A, calcium and sodium/salt, which were all lower than the NDNS. Conclusions: This study contradicts the stereotypical assumption that students are following a high energy, fat, saturated fat, total sugars, salt and alcohol diet compared with the general population.

Abstract
Despite the clear nutritional advantages of wholemeal breads, their consumption is lower than recommended, mainly due to their lower organoleptic quality. This paper proposes the use of psyllium to improve the quality of these breads. For this aim, a wholemeal bread control is compared to breads with psyllium added in different amounts (1 to 10%). Mixolab was used to analyse dough behaviour. Specific volume, texture, macronutrient composition, and bread acceptability were also analysed. Increasing amounts of psyllium resulted in an increased dough hydration and stability, but a reduced kneading time. Specific volume and weight loss were not affected, despite the higher hydration level of the doughs. The addition of psyllium reduced bread hardness and increased its cohesiveness and resilience, thus lowering staling. The addition of psyllium also reduced the calorie content of the breads, due to increased moisture and fibre content. Moreover, the addition of up to 5% psyllium clearly improves the acceptability of wholemeal breads. The use of psyllium can improve the organoleptic and nutritional quality of wholemeal breads, improving their acceptability by consumers.

Abstract
Grains are important sources of carbohydrates in global dietary patterns. The majority of these carbohydrates, especially in refined-grain products, are digestible. Most carbohydrate digestion takes place in the small intestine where monosaccharides (predominantly glucose) are absorbed, delivering energy to the body. However, a considerable part of the carbohydrates, especially in whole grains, is indigestible dietary fibers. These impact gut motility and transit and are useful substrates for the gut microbiota affecting its composition and quality. For the most part, the profile of digestible and indigestible carbohydrates and their complexity determine the nutritional quality of carbohydrates. Whole grains are more complex than refined grains and are promoted as part of a healthy and sustainable diet mainly because the contribution of indigestible carbohydrates, and their co-passenger nutrients, is significantly higher. Higher consumption of whole grain is recommended because it is associated with lower incidence of, and mortality from, CVD, type 2 diabetes, and some cancers. This may be due in part to effects on the gut microbiota. Although processing of cereals during milling and food manufacturing is necessary to make them edible, it also offers the opportunity to still further improve the nutritional quality of whole-grain flours and foods made from them. Changing the composition and availability of grain carbohydrates and phytochemicals during processing may positively affect the gut microbiota and improve health.

Abstract
Bread is a vehicle for a range of nutrients within the Australian diet, but has been the target of negative press. The aim of this study was to examine bread products, particularly white, whole grain and gluten-free loaves, including nutrients, health claims and Health Star Rating (HSR). An audit of four supermarkets and a bakery franchise (2017) was compared with 2014 data. Median and range was calculated for whole grain content, dietary fibre, sodium, protein, carbohydrate and sugar. Of all breads (n = 456), 29% were eligible to make a whole grain claim with 27% very high in whole grain (≥24 g/serve), an 18% increase from 2014. Within loaves (n = 243), 40% were at least a source of whole grain (≥8 g/serve), 79% were at least a source of dietary fibre, 54% met the sodium reformulation target (≤400 mg/100 g), 78% were a 'source' and 20% were a 'good source' of protein (10 g/serve), and 97% were low in sugar. Despite significant differences between loaves for all nutrients assessed, HSR did not differ between white and whole grain varieties. Compared to 2014, there were 20 fewer white loaves and 20 additional whole grain loaves which may assist more Australians achieve the 48g whole grain daily target intake.
