Abstract

Purpose

Due to the increase in the prevalence of other risk factors of heart diseases, the age of heart disease has decreased and it has led to premature heart disease. One of the main risk factors of this disease is metabolic syndrome (MetS). One of the key ways to control MetS is dietary modification. The purpose of this study is to investigate the relationship between dietary patterns and MetS in patients with premature heart disease.

Design/methodology/approach

This study was conducted on 409 people with premature heart disease. The diagnosis of MetS was made based on the ATP III criteria. Dietary intake for the past year was collected using the validated semi-quantitative food frequency questionnaire. Dietary patterns were determined by factor analysis with principal components approach.

Findings

Three dietary patterns were identified, including the healthy, western and traditional patterns. The findings showed that people who followed the traditional pattern more than those who followed less had a lower risk of MetS. (OR:0.23; 95% CI: 0.11–0.52). But, no relation was observed between healthy (OR:1.45; 95% CI:0.64–3.25) and western (OR:1.04; 95% CI:0.51–2.13) patterns with MetS.

Originality/value

The findings of this study showed that following a traditional dietary pattern based on high consumption of whole grains, red meat, viscera, fish, eggs, high-fat dairy products, soft drinks, mayonnaise and solid oil was associated with a lower risk of MetS.

Abstract

Purpose

This study sought to understand which food allergen labeling systems (non-directive, semi-directive, and directive) were attended to and preferred by 34 participants with food hypersensitivity and their perceived corporate social responsibility (CSR) and behavioral intention towards a restaurant that identifies food allergens on menus.

Design/methodology/approach

This study used an online survey with open-ended and ranking questions, combined with eye-tracking technology, to explore participants' visual attention and design preferences regarding four menus. This study utilized one-way repeated measures analysis of variance (RM-ANOVA) and heat maps to analyze participants' menu-reading behaviors. A content analysis of survey responses and a ranking analysis of menus were conducted to understand the reasons behind consumers' preferred menu designs.

Findings

The advisory statement was not much attended to. Participants identified food allergen information significantly quicker with the directive labeling system (icons) than the other two systems, implying they were eye-catching. Semi-directive labeling system (red text) has lower visit count and was more preferred than two other systems; each labeling system has its strengths and limitations. Participants viewed restaurants that disclosed food allergen information on menus as socially responsible, and they would revisit those restaurants in the future.

Originality/value

This study was one of the first to explore, through use of eye-tracking technology, which food allergen labeling systems were attended to by consumers with food hypersensitivity. The use of triangulation methods strengthened the credibility of the results. The study provided empirical data to restauranteurs in the US on the values of food allergen identification on restaurant menus, although it is voluntary.

Abstract

Purpose

The paper aims to explore how values and knowledge are expressed in student’s discussions about food and health.

Design/methodology/approach

Food practices present a complex phenomenon extending beyond biomedical descriptions, including social dynamics of food in families and communities. Contextual conditions of social groups and settings have significant impacts on food choices and practices. Although values constitute a central part of educational goals, deliberate values education remains an often-neglected area, with a tendency in both curricula and educational practice to focus on knowledge and overlook how values intersect with knowledge. The paper utilises group interviews supported by participant observations to study the food and health practices as expressed in students' discussions.

Findings

The paper’s findings show how values are expressed together with knowledge as value-knowledges around food and health within the social contexts of family, cultural identities and peer relationships. While moving through their lives, students draw on and utilise biomedical, social-cultural and sensory value-knowledges, simultaneously considering the nutrition and taste of foods, the value of connecting with family and peers in cultural settings as well as getting enough food to feel satiated.

Originality/value

The paper presents an original approach around the necessity to consider and integrate cultural identities in discussions and education about food and health to empower students and their communities in a way that is socially just and equitable. This involves shifting discussions of health education away from students as (ir)rational obstacles but rather as partners in co-creating knowledge for sustainable food and health equity.

Abstract

Considering sustainability and resilience together is crucial in food supply chain (FSC) management, as it ensures a balanced approach that meets environmental, economic and social needs while maintaining the system's capacity to withstand disruptions. Towards this, a multi-objective optimisation model is proposed in this study to create an integrated sustainable and resilient FSC. The proposed model employs four objective functions – each representing a dimension of sustainability and one for resilience and utilises an augmented ϵ-constraint method for solving. The findings highlight the interplay between sustainability aspects and resilience, illustrating that overemphasis on any single dimension can adversely affect others. Further, the proposed model is applied to the case of Indian mango pulp supply chain and several inferences are derived. The proposed model would assist decision-makers in making a well-balanced choice based on sustainability and resilience considerations.

Abstract

Purpose

The warehouse receipt system (WRS) is critical for farmers because it addresses agricultural market inefficiencies, provides credit access, reduces postharvest losses and increases access to profitable markets. However, its use and implementation across the commodity value chain remain relatively limited in Sub-Saharan Africa, particularly among cash crop producers. This study examines cashew farmers' perceptions of WRS implementation and determinants of farmer participation.

Design/methodology/approach

A total of 153 cashew farmers from the Bono region of Ghana were sampled using a multistage sampling approach. Perception index analysis and Cragg's double hurdle model were used for the analysis.

Findings

The results revealed that farmers strongly perceived that WRS augmented credit and market access. In addition, farm size, household size, annual income, perception of collateral and higher selling price determined farmers' willingness to participate in WRS.

Research limitations/implications

Despite the existence of other cashew farmers in Ghana, the study was limited to cashew farmers in Bono Region.

Originality/value

Despite the plethora of benefits of WRS, it is surprising that its implementation in the cashew subsector is geographically limited to East Africa. Thus, this study is the first to provide empirical evidence on the perception of WRS implementation and further examine farmers' willingness to participate in WRS in Ghana.

Abstract

Purpose

Research indicated that dietary antioxidants could improve immune system performance. This study aims to investigate the association of COVID-19 symptoms, total antioxidant capacity and serum inflammatory markers, with dietary antioxidants intake among angina patients.

Design/methodology/approach

A food frequency questionnaire was used in a cross-sectional study among 135 angina patients with COVID-19, to assess dietary antioxidants consumption. Serum levels of tumor necrosis factor, interleukin 1ß, malondialdehyde, high-sensitivity C-reactive protein and total antioxidant capacity were measured by enzyme-linked immunosorbent assay methods.

Findings

Among study angina patients, 76.67% followed unhealthy food patterns and 23.33% followed anti-inflammatory dietary patterns before hospitalization. The angina patients with anti-inflammatory food pattern had less fever (p = 0.021), cough (p = 0.018), dyspnea (p = 0.024), diarrhea (p = 0.014) and pneumonia severity index (p = 0.014) compared to patients with unhealthy food pattern. The serum levels of tumor necrosis factor, interleukin 1ß, high-sensitivity C-reactive protein and malondialdehyde, had a significantly negative association with dietary antioxidants intake (p < 0.05).

Originality/value

There are significant association between antioxidant intake with serum inflammation markers in COVID-19 patients. There is a need for more clinical trial studies for approval of these results.

The present study provides evidence on export advantages of horticultural commodities based on competitiveness, trade balance and seasonality dimensions.

Abstract

Purpose

The present study provides evidence on export advantages of horticultural commodities based on competitiveness, trade balance and seasonality dimensions.

Design/methodology/approach

The study delineated horticultural commodities in terms of comparative advantage, examined temporal shifts in export advantages (mapping) and estimated seasonality. Product mapping was carried out using the Revealed Symmetric Comparative Advantage (RSCA) and Trade Balance Index (TBI). Seasonal advantages were examined through a graphical approach along with the objective tests, namely, modified QS-test (QS), Friedman-test (FT) and using a seasonal dummy.

Findings

Cucumbers/gherkins, onions, preserved vegetables, fresh grapes, shelled cashew nuts, guavas, mangoes, and spices emerged as the most favorable horticultural products. India has a strong seasonal advantage in dried onions, cucumber/gherkins, shelled cashew nut, dried capsicum, coriander, cumin, and turmeric. The untapped potential in horticulture can be addressed by handling the trade barriers effectively, particularly the sanitary and phytosanitary issues, affecting the exports. Proper policies must be enacted to facilitate the investment in advanced agricultural technologies and logistics to ensure the desired quality and cost effectiveness.

Research limitations/implications

Commodity-specific studies on value chain analysis would provide valuable insights into the issues hindering exports and realizing the untapped export potential.

Originality/value

There is no holistic and recent study illustrating the horticulture export advantages covering a large number of commodities in the Indian context. The study would be helpful to the stakeholders for drawing useful policy implications.

Abstract

Purpose

Studies on developed economies showed that imposing taxes on animal-based foods could effectively reduce agricultural greenhouse gas emissions (AGHGEs), while this taxation may not be appropriate in developing countries due to the complex nutritional status across income classes. Hence, this study aims to explore optimal tax rate levels considering both emission reduction and nutrient intake, and examine the heterogenous effects of taxation across various income classes in urban and rural China.

Design/methodology/approach

The authors estimated the Quadratic Almost Ideal Demand System model to calculate the price elasticities for eight food groups, and performed three simulations to explore the relative optimal tax regions via the relationships between effective animal protein intake loss and AGHGE reduction by taxes.

Findings

The results showed that the optimal tax rate bands can be found, depending on the reference levels of animal protein intake. Designing taxes on beef, mutton and pork could be a preliminary option for reducing AGHGEs in China, but subsidy policy should be designed for low-income populations at the same time. Generally, urban residents have more potential to reduce AGHGEs than rural residents, and higher income classes reduce more AGHGEs than lower income classes.

Originality/value

This study fills the gap in the literature by developing the methods to design taxes on animal-based foods from the perspectives of both nutrient intake and emission reduction. This methodology can also be applied to analyze food taxes and GHGE issues in other developing countries.

Abstract

Purpose

Transitional periods are important for people, such as birth, marriage and death, are important times when ceremonial meals are prepared and served and certain practices are carried out. These periods and the practices constitute our gastronomic cultural heritage. In order to keep our cultural heritage alive and pass it on to future generations, existing values must first be identified and recorded. For this reason, in this study, gastronomic practices of Mentese's transitional periods were examined within the scope of intangible cultural heritage.

Design/methodology/approach

In this research, data was collected using ethnographic design, which is one of the qualitative research methods, and document analysis, interviews and focus group studies, as well as participant observation techniques and image/audio materials. The sample was determined using snowball sampling, convenience sampling and maximum diversity sampling methods. In the analysis of the data, themes and codes related to gastronomic practices in transitional periods were created and direct quotations were included with a descriptive approach.

Findings

It has been found that traditions are kept more alive in rural areas, while those living in the city centres no longer perform these practices dating back to the ancient times. Participants attribute the main reason for this to the fact that economic conditions are not favourable and that some traditional practices are “unnecessary” today. While wedding meals, which are the main part of the weddings, used to be made by women in the past, they are now mostly made by catering companies.

Research limitations/implications

It was accepted that some of the participants started to give short answers as the duration of the interview increased and that the answers given were limited to what the participants could remember.

Originality/value

This study reveals special day meals and practices, rituals and traditions related to food within the scope of Mentese's culinary culture, which has a very deep-rooted history. In this regard, in addition to making an important contribution to the literature, the study also contributes to the articles about “recording and promoting the culture” mentioned in the Intangible Cultural Heritage convention.

Abstract

Purpose

Cataract, or lens opacification, is a major public health burden accounting for more than half of all blindness worldwide. Plant-based dietary indices provide a unique approach to investigating a modifiable risk for age-related cataracts (ARC). The purpose of this study was to investigate the association between plant-based diet indices and risk of ARC.

Design/methodology/approach

This case-control study was conducted on 97 patients with newly diagnosed ARC and 198 healthy people (as a control group) in Iran. Convenience sampling and a food frequency questionnaire were used. Three plant-based dietary indices were used based on the health promoting qualities of food items, the overall plant-based diet index (PDI), healthful plant-based diet index (H-PDI) and unhealthful plant-based diet index (U-PDI) which comprised refined carbohydrates and highly processed foods. The plant-based dietary indices were used to investigate relationships with risk of ARC.

Findings

After adjusting for potential covariates, no significant association between a higher adherence to O-PDI and risk of ARC. As well, a higher adherence to H-PDI was inversely associated with the risk of ARC (OR = 0.35,95%CI:0.16–0.78). In contrast, there was a significant positive association between a higher adherence to U-PDI and the risk of ARC (OR = 3.67,95%CI:1.66 – 8.15).

Originality/value

The findings of this study have underscored the potential impact of the quality of plant-based food selections on the likelihood of developing ARC. Therefore, adopting a plant-based diet that is rich in nutrient-dense plant-based foods while being low in unhealthy options may have the potential to reduce the risk of ARC.
