Abstract

Purpose

Because dietary fibre has been recognized as a major ally to the maintenance of a healthy body as well as to help against the development of some chronic diseases, this paper aims to study the level of knowledge of a relatively wide range of people about the health effects related to the ingestion of dietary fibre in appropriate dosages.

Design/methodology/approach

A descriptive cross-sectional study was undertaken on a non-probabilistic sample of 6,010 participants. The data were collected from 10 countries in three different continents (Europe, Africa and America) and measured the level of knowledge regarding different health benefits from dietary fibre. The questionnaires were applied by direct interview after verbal informed consent.

Findings

The results obtained considering the general level of knowledge revealed a considerable degree of information about the benefits of fibre (average score of 3.54 ± 0.5, on a scale from 1 to 5). There were significant differences between genders (p < 0.001), with higher average score for women, and also for level of education (p < 0.001), with higher score for university level. The living environment also showed significant differences (p < 0.001), with people living in urban areas showing a higher degree of knowledge. Also for countries the differences were significant (p < 0.001), with the highest score obtained for Portugal (3.7), and the lowest for Croatia, Italy, Latvia, Macedonia and Romania (3.5). However, despite these differences, the results showed that for all the countries the degree of knowledge was good (above 3.5), corresponding to a minimum level of knowledge of 70 per cent.

Originality/value

This work is considered important due to the wide coverage, including so many countries inclusive with different social and cultural settings. The study allowed concluding that, in general, the participants in the study were quite well informed about the benefits of dietary fibre for the improvement of human health, regardless of gender, level of education, living environment or country. This finding is very relevant considering the diversity of people that composed the sample and reinforces the necessity of continuing with educational policies aimed at providing the general population with the knowledge that might help them make appropriate food choices.

Abstract

Purpose

The purpose of this paper is to evaluate the latest mounting evidence reporting associations between the important role of whole grains and fibre in lowering the risk of chronic diseases and health.

Design/methodology/approach

A general systematic review was conducted to locate and summarise up-to-date published studies within the field. A Medline search identified human-controlled trials and observational studies published in the past five years.

Findings

A total of 49 studies were identified. In observational studies, higher intakes of whole grain and dietary fibre were associated with a significantly lower risk of cardiovascular disease, diabetes, abdominal adiposity and certain cancers. This was further supported by human intervention trials, which reported benefits for appetite control, blood lipid levels, glycaemic control, digestive health and secondary cancer prevention. Mechanisms may relate to the micronutrients and phytonutrients present in high fibre foods.

Practical implications

Practical advice is needed to help people identify foods rich in whole grains, e.g. breakfast cereals. UK fibre recommendations should be aligned with European guidelines and food labelling regulations, and a whole grain dietary recommendation, e.g. similar to the US guideline of three portions a day, could be introduced. Government and industry should play a role in communicating dietary fibre guidelines and the health benefits associated with whole grain and fibre, particularly insoluble fibre.

Originality/value

This paper develops knowledge about whole grains, health and the importance of establishing whole-grain dietary recommendations.

Abstract

Purpose

Numerous randomized clinical studies have shown that psyllium fiber lowers serum cholesterol in patients with hyperlipidemia and is thus recognized by the US Food and Drug Administration (FDA) as a dietary fiber that may help reduce the risk of coronary heart disease (CHD) by lowering cholesterol. The purpose of this paper is to assess the potential economic implications for health-care cost savings and quality of life productivity gains if the cholesterol-lowering effect of psyllium, consumed daily as a fiber supplement, could be applied to a broad at-risk population.

Design/methodology/approach

A cost-benefit analysis tool was used to examine evidence that the use of psyllium as a cholesterol-lowering agent can reduce overall CHD-attributed medical care service costs in the USA among those at high risk of experiencing disease-related events.

Findings

Results of the analysis showed that the potential net annual avoided medical care service costs and annual quality of life productivity gains among US adults 45 and older with low-density lipoprotein (LDL) cholesterol levels = 130 mg/dL could be up to an average of $870m per year from 2013 to 2020 if everyone in the target population used seven grams of soluble fiber from psyllium daily, corresponding to a net benefit-cost ratio of $1.19 savings in annual medical service cost and annual productivity gains per $1 spent on a psyllium regimen.

Originality/value

Thus, the use of psyllium fiber as a daily supplement could be recommended as a means to help control the risk for potentially costly cardiovascular-related medical events and to maximize the economic potential for an improved quality of life in adults 45 and older with LDL cholesterol levels =130 mg/dL.

Abstract

Purpose

The paper aimed to explore the factors leading to lower rates of whole grain consumption amongst the Malaysian adult population according to the Reasoned Action Approach (RAA) model.

Design/methodology/approach

This paper employed a qualitative approach to explore the factors that influence whole grain consumption. Individual interviews were conducted online amongst Malaysian adults aged 18 years and above who purchase groceries and are responsible for food preparation at home. Interviews were transcribed verbatim and analysed thematically using the NVivo version 12 software.

Findings

A majority of the respondents (N = 30; mean age = 39.2 years old) were females (n = 19, 63.3%) and lived in urban areas (n = 23, 76.7%). Even though over 86.7% of respondents (n = 26) had consumed whole grain products, a majority of them had inadequate knowledge surrounding whole grains (n = 25, 83.3%). Predominant barriers to whole grain consumption were perceived cost (n = 30, 100%), dislikes towards the sensory aspects of whole grain foods (n = 28, 93.3%), inadequate knowledge in identifying whole grains in foods (n = 25, 83.3%), poor awareness (n = 25, 83.3%), lack of knowledge in preparation of whole grain foods (n = 25, 83.3%), a wide variety of other tasty cuisine alternatives in Malaysia (n = 25, 83.3%), low availability and accessibility of whole grain products (n = 18, 60%), cultural eating behaviours (n = 17, 56.7%) and family influence (n = 16, 53.3%). Besides that, having a longer preparation time, restrictive diets and social influences were minor barriers.

Research limitations/implications

This study addresses the barriers that should be highlighted in future health educational interventions, and presents a challenge to the food industry to develop whole grain foods which are easily accepted by consumers.

Originality/value

This is the first paper to outline the factors associated with poor consumption of whole grains amongst the Malaysian adult population.

Abstract

Purpose

Edible flowers have traditionally been consumed for their nutritional and medicinal properties. Aponogeton distachyos is an aquatic flowering plant native to the Western Cape of South Africa (SA) that used to be a wild plant gathered during the winter months, but it is now considered to be underutilised and endangered. This study aims at gaining insights from different stakeholders into the activities across the plant value chain and their impact on the consumption of Aponogeton distachyos.

Design/methodology/approach

The study methodology involved the identification of different stakeholders in the plant value chain and conducting qualitative in-depth interviews during the data collection. Twelve study participants were selected via purposive sampling and interviewed using semi-structured interviews (face-to-face, telephone and online).

Findings

Nostalgic connection of the flower with local culture and heritage and its unique taste and flavour are key consumption drivers. Promotional and educational efforts by food advocates and at public events help raise consumer awareness, which is generally lacking. Limited geographic and seasonal availability, perishability, price and quality issues emerged, together with low awareness, as main barriers to more frequent and geographically spread consumption.

Originality/value

Although wild edible flowers have been consumed for centuries, there has been little attention to their nutritional value and journey to their final consumers. The present study identifies important challenges emanating at different stages of the food value chain to consumption of one particular neglected and underutilised plant, with certain implications for people's dietary quality, environmental sustainability and biodiversity of natural resources beyond Aponogeton distachyos and SA.

Highlights

(1)Aponogeton distachyos is a neglected and underutilised aquatic flowering plant native to the Western Cape of South Africa (SA). (2)The plant offers benefits related to people's dietary quality, environmental sustainability and biodiversity of natural resources. (3)Flower's nostalgic connection with local culture and heritage emerge as a key consumption driver. (4)Its unique taste and flavour highly appeal to consumers. (5)Low awareness, limited availability, price and quality are main consumption barriers. (6)There is largely unexploited public policy potential for supporting dietary diversity through growing edible flowers.

Abstract

Purpose

Sorghum is quite comparable to wheat, rich source of nutrients with various health benefits, and therefore considered as a grain of future. The purpose of this paper is to review the bioactive active compounds, health benefits and processing of the sorghum. Sorghum is utilized for animal feeding rather than the human food usage. Therefore, this paper focuses on the emerging new health foods with benefits of the sorghum.

Design/methodology/approach

Major well-known bibliometric information sources searched were the Web of Science, Google Scholar, Scopus and PubMed. Several keywords like nutritional value of sorghum, bioactive compounds present in sorghum, health benefits of sorghum and processing of sorghum were chosen to obtain a large range of papers to be analyzed. A final inventory of 91 scientific sources was made after sorting and classifying them according to different criteria based on topic, academic field country of origin and year of publication.

Findings

From the literature reviewed, sorghum processing through various methods, including milling, malting, fermentation and blanching, bioactive compounds, as well as health benefits of sorghum were found and discussed.

Originality/value

Through this paper, possible processing methods and health benefits of sorghum are discussed after detailed studies of literature from journal articles.

Abstract

Purpose

The purpose of this paper is to examine a case study for increasing supply of, and demand for, healthier food in the metropolitan Borough of Sandwell, West Midlands, UK. Sandwell has a declining and ageing population. Levels of cancer, coronary heart disease, diabetes and obesity are all high. These diseases should not just be regarded as medical problems with medical solutions. By considering both the built environment and the population's health the paper aims to demonstrate how local action is driving strategic food policy.

Design/methodology/approach

Food mapping and children's food/obesity prevalence research provided the evidence base for a locally appropriate approach. From ongoing work generated by this evidence base, Sandwell's food policy has been developed to provide a focus and framework for action. This strategic approach has led to the development of neighbourhood renewal funded work “Eatwell in Sandwell”.

Findings

By working in partnership with the private sector, i.e. retail businesses and specialist consultants, it is shown that bridges can be built between public health and the private sector to the benefit of both. For some people living in neighbourhoods with poor or non‐existent fresh produce provision, the Eatwell shops have brought about the regeneration of not just the shops, but also of the shopping habits that were previously difficult or impossible. It is suggested that food must regain its centrality to people's daily lives, not only to improve health, but also to ensure sustainable communities for the next generation.

Originality/value

This paper is a useful source for researchers/students with interests in the topics of food poverty, public health and food retail access

This paper aims to evaluate the association between carbohydrate quality index (CQI) and nutrient adequacy in Iranian adults.

Abstract

Purpose

This paper aims to evaluate the association between carbohydrate quality index (CQI) and nutrient adequacy in Iranian adults.

Design/methodology/approach

A total of 268 men and women with ages ranged from 18 to 70 years were evaluated in a cross-sectional study. The CQI was calculated by adding together the three components, namely, the ratio of solid to total carbohydrate, dietary fiber and glycemic index. The scores of three components were summed to calculate the CQI, with a higher score indicating a higher dietary carbohydrate quality. The odds ratios (ORs) of nutrient adequacy ratio (NAR), defined as the ratio of intake of a nutrient to the age- and gender-specific recommended dietary allowance, for the intake of energy and 10 nutrients across quartiles of the CQI were calculated by logistic regression analysis and expressed with 95% confidence intervals (CIs).

Findings

CQI ranged between 3 to 15 (mean ± SD: 9 ± 1.9). Being in top versus bottom quartile of the CQI was associated with a higher NAR of folic acid (OR: 3.20, 95% CI: 1.06–9.62; P-trend: <0.001), vitamin A (OR: 3.66; 95% CI: 1.46–9.17; P-trend: <0.001), magnesium (OR: 5.94; 95% CI; 1.71–20.53; P-trend: <0.001), vitamin C (OR: 7.85; 95% CI; 2.99–20.59; P-trend: <0.001).

Originality/value

A higher CQI was associated with greater micronutrient consumption adequacy in Iranian adults. The results suggest that increasing the consumption of total fiber and solid carbohydrates and decreasing the glycemic index of the diet and liquid carbohydrates can improve micronutrient intake adequacy.

Abstract

Many committees have commented on the role of diet and health, but in the last 15 years there has been an upsurge of these publications. One of the first reports in 1974 from the committee on Medical Aspects of Food Policy (COMA) made very little reference to fruits and vegetables and did not have any specific recommendations to increase their consumption. Yet the World Health Organisation Expert Committee in 1982 published a report Prevention of CHD that recommended increasing ‘appropriately combined foods of plant origin’. The discussion paper Proposals for Nutritional Guidelines for Health Education in Britain' prepared by a working party of the National Advisory Committee of Nutrition Education (NACNE) stated, ‘… health educators should encourage the consumption of fruits and vegetables as well as cereals …’

Abstract

Purpose

Healthy and safety food issues are more and more becoming the purchasing process core of conscious consumer. “Type 1” wheat flour means higher protein and ash content. The purpose of this paper is to investigate the attributes usually referred to the characteristics of wheat flour known to consumers and at implementing a predictive model of purchasing that allows to make correct decisions without the necessary experience of a real human expert.

Design/methodology/approach

In order to investigate the research aims of the paper, an online survey was carried out and conducted by means of the Google Forms in the detection time January-April 2016. The online survey collected responses from 467 Italian respondents asked to give feedback about their buying habits of various types of flour. The responses were analyzed through a data mining approach. This paper implements predictive analytics to create a statistical model of future behavior by means of a machine learning algorithms.

Findings

In line with recent healthy and dynamic trends in the food industry, conscious consumer seems to be willing to pay a price for “type 1” wheat flour that is four times higher than the price related to the basic types of wheat flour.

Social implications

Consumer seems not to know well the “type 1” wheat flour and its healthy characteristics; then, it should be crucial to implement promotional strategies and marketing hand in hand. Promotion can be a key element in putting across the health benefits of special kinds of wheat flour.

Originality/value

Highlighting health issues about the “type 1” wheat flour gives insights and sheds some light on the crucial need of changing eating and purchasing behavior. Then, originality of this paper can be found in the used predictive algorithm of the artificial intelligence.
