Health, food and social inequality: critical perspectives on the supply and marketing of food

Health, Food and Social Inequality investigates how vast amounts of consumer data are used by the food industry to enable the social ranking of products, food outlets and consumers themselves, and how this influences food consumption patterns. This book supplies a fresh social scientific perspective on the health consequences of poor diet. Shifting the focus from individual behaviour to the food supply and the way it is developed and marketed, it discusses what is known about the shaping of food behaviours by both social theory and psychology. Exploring how knowledge of social identities and health beliefs and behaviours are used by the food industry, Health, Food and Social Inequality outlines, for example, how commercial marketing firms supply food companies with information on where to locate snack and fast foods whilst also advising governments on where to site health services for those consuming such foods disproportionately. Giving a sociological underpinning to Nudge theory while simultaneously critiquing it in the context of diet and health, this book explores how social class is an often overlooked factor mediating both individual dietary practice and food marketing strategies. This innovative volume provides a detailed critique of marketing and food industry practices and places class at the centre of diet and health. It is suitable for scholars in the social sciences, public health and marketing.

Evidence and Experience of Open Sustainability Innovation Practices in the Food Sector

The adoption of an “open sustainability innovation” approach in business could be a strategic advantage to reach both industry objectives and sustainability goals. The food sector is facing a constant increase in competition. In order to address the high competition that involves the food industry, sustainability and innovation practices can be strategically effective, especially with an open sustainability innovation approach. In the literature, we found many examples of open innovation applications and their implications for sustainable strategy. These applications are important for reducing cost and time to market, as well as for a company’s impact on the environment and food security. In this paper, the authors show the evidence of these implications. In particular, starting from the state of the art of the food sector, we highlight the empirical results of ten case studies. By analyzing these cases, we can gain a better awareness on how and why these approaches are currently being applied by food sector companies.

Celiac & Gluten Intolerance: A Wellness Perspective

The popularity of the gluten-free diet is driven by misconceptions concerning its efficacy for everything from weight control to sports performance. It is time to step back and review the current state of diagnostic methods, diet treatment, and the health-related outcomes of celiac and gluten-sensitive individuals. This review was undertaken to propose changes to wellness promotion and food industry practices for people who are in the gluten intolerant spectrum, and to identify opportunities for research in nutrition and wellness products and services.

A Q methodology study of stakeholders’ views about accountability for promoting healthy food environments in England through the Responsibility Deal Food Network

In March 2011, the United Kingdom’s (UK’s) Government launched five Public Health Responsibility Deal Networks to address public health priorities. The Networks used voluntary partnerships to influence peoples’ choice architecture to move them toward healthier behaviors. The purpose of this research was to conduct an exploratory study of diverse stakeholders’ perspectives about perceived responsibility and accountability expectations to improve food environments in England through the Food Network partnerships. A purposive sample of policy elites (n=31) from government, academia, food industry and non-government organizations sorted 48 statements related to improving food environments in England. Statements were grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). PQMethod 2.33 statistical software program used factor analysis to identify viewpoints based on intra-individual differences for how participants sorted statements. The results revealed three distinct viewpoints, which explained 64% of the variance for 31 participants, and emphasized different expectations about responsibility. The food environment protectors (n=17) underscored government responsibility to address unhealthy food environments if voluntary partnerships are ineffective; the partnership pioneers (n=12) recognized government–industry partnerships as legitimate and necessary to address unhealthy food environments; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected government intervention to improve food environments. Consensus issues included: protecting children’s right to health; food industry practices that can and should be changed; government working with industry on product reformulation; and building consumer support for economically viable healthy products. Contentious issues were: inadequacy of accountability structures and government inaction to regulate food marketing practices targeting children. We conclude that understanding different viewpoints is a step toward building mutual trust to strengthen accountability structures that may help stakeholders navigate ideologically contentious issues to promote healthy food environments in England.

Creating healthy food environments through global benchmarking of government nutrition policies and food industry practices

Unhealthy processed food products are increasingly dominating over healthy foods, making food and nutrition environments unhealthier. Development and implementation of strong government healthy food policies is currently being circumvented in many countries by powerful food industry lobbying. In order to increase accountability of both governments and the private sector for their actions, and improve the healthiness of food environments, INFORMAS (the International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support) has recently been founded to systematically and comprehensively monitor food environments and policies in countries of varying size and income. This will enable INFORMAS to rank both governments and private sector companies globally according to their actions on food environments. Identification of those countries which have the healthiest food and nutrition policies and using them as international benchmarks against which national progress towards best practice can be assessed, should support reductions in global obesity and diet-related NCDs.

Freeze-Drying Changes the Structure and Digestibility of B-Polymorphic Starches

Starch granules both isolated from plants and used in foods or other products have typically been dried. Common food laboratory and industry practices include oven (heat), freeze, and ethanol (solvent-exchange) drying. Starch granules isolated from maize (A-type polymorph) and potato (B-type polymorph) were used to understand the effects of different dehydration methods on starch structure and in vitro digestion kinetics. Oven and ethanol drying do not significantly affect the digestion properties of starches compared with their counterparts that have never been dried. However, freeze-drying results in a significant increase in the digestion rate of potato starch but not maize starch. The structural and conformational changes of starch granules after drying were investigated at various length scales using scanning electron microscopy, confocal laser scanning microscopy, X-ray diffraction, FTIR spectroscopy, and NMR spectroscopy. Freeze-drying not only disrupts the surface morphology of potato starch granules (B-type polymorph), but also degrades both short- and long-range molecular order of the amylopectin, each of which can cause an increase in the digestion rate. In contrast to A-polymorphic starches, B-polymorphic starches are more disrupted by freeze-drying, with reductions of both short- and long-range molecular order. We propose that the low temperatures involved in freeze-drying compared with oven drying result in greater chain rigidity and lead to structural disorganization during water removal at both nanometer and micrometer length scales in B-type polymorphic starch granules, because of the different distribution of water within crystallites and the lack of pores and channels compared with A-type polymorphic starch granules.

Obtaining Bacteriocins by Chromatographic Methods

Bacteriocins are a large group of chromosome or plasmid-encoded and ribosomally synthesized low-molecular-weight (2 to 6 kDa) antimicrobial and amphiphilous peptides produced by Gr+ or Gr- bacteria [1]. Their low toxicity as well as the absence of allergenicity and reactogenicity is confirmed by testing selected bacteriocins [2] [3]. Bacteriocins can be widely used as preservatives and antibiotic alternatives in medicine. Nisin, a Streptococcus lactis-derived bacteriocin, has been in practice in food industry for a long time. A relevant product contains about 2.5% of nisin. For medical use (e.g., when injected into the blood stream), highly purified drugs are required. However, the yield of bacteriocins accounts for no more than a few percents from the total activity in the culture liquid. In this paper, we propose methods (by example of two B. subtilis strains), allowing to increase the yield up to ~80%. It is believed that other bacteriocins may be purified by these methods and with the same yield.

Contemporary nutritional transition: determinants of diet and its impact on body composition.

The world has experienced a marked shift in the global BMI distribution towards reduced undernutrition and increased obesity. The collision between human biology, shaped over the millennia and modern technology, globalization, government policies and food industry practices have worked to create far-reaching energy imbalance across the globe. A prime example is the clash between our drinking habits and our biology. The shift from water and breast milk as the only beverages available, to a vast array of caloric beverages was very rapid, shaped both by our tastes and aggressive marketing of the beverage industry. Our biology, shaped over millennia by daily consumption of water and seasonal availability of food, was not ready to compensate for the liquid energies. Other dietary changes were similarly significant, particularly the shift towards increased frequency of eating and larger portions. The roles of the food and beverage production, distribution and marketing sectors in not only shaping our diet but also accelerating these changes must be understood. Apart from the role of beverages, there is much less consensus about the role of various components of our diet in energy imbalance. Understanding the determinants of change in the key components of our diet through an array of research provides insights into some of the options we face in attempting to attain a great balance between energy intake and expenditures while creating an overall healthier dietary pattern. A few countries are systematically addressing the causes of poor dietary and physical activity patterns and high energy imbalance.

Meat handlers training in Portugal: A survey on knowledge and practice

Professional training for meat handlers is an European Community food law requirement in order to apply HACCP principles and achieve food safety goals. A self-administered questionnaire designed to assess “Knowledge” and “Practice” of public hygiene measures was completed by meat handlers (MH) ( n = 159) in slaughterhouses in Portugal. A significant proportion of the group (72.7%) has had professional training in two different areas: Good Practice in Food Industry (12.03%) and Work Safety and Hygiene (22.8%); 37.9% of the respondents have had training in both areas. However 24.5% of the subjects have never had training. Meat handlers with professional training in Good Practice in Food Industry (GPFI) and in both areas (BT) have had the highest proportions of correct answers in Knowledge (66.92 ± 16.36 and 67.26 ± 21.05, respectively) and Practice questions (70.53 ± 17.47 and 68.67 ± 22.58, respectively). The results of this study point to the need to improve training, particularly in Good Practice in Food Industry, thus enabling meat handlers to achieve more correct answers in Knowledge and Practice. The development of evaluation criteria for the effectiveness of professional training is crucial to protect Public Health.

Bringing political economy into the debate on the obesity epidemic

This paper takes what has been termed the “epidemic of obesity” as the point of departure to examine the way in which political economic factors intersect with diet and nutrition to determine adverse health outcomes. The paper proposes several concepts to better understand the dynamics of the “foodscape” – institutional sites for the merchandising and consumption of food. These include the concepts of “spatial colonization” and “pseudo foods.” With a focus on critical dimensions of the contemporary “foodscape,” principally supermarket merchandising practices, as well as trends in other food vending operations, the paper explores incentives that motivate capital to “spatially colonize” the foodscape with aggressively promoted high fat/high sugar “pseudo foods.” The paper reports on extensive research on trade industry publications as well as data collected through onsite investigations of supermarket practices of the three largest Canadian retail supermarket operations. In addition, current merchandising practices of convenience chain store operations and some non-traditional food vending sites are examined. In concluding, it is argued that the rapidly evolving interdisciplinary debate around the obesity crisis would benefit considerably from the insights to be gained from political economic analysis of retail food industry practices and trends.

The duration of breast-feeding: How is it affected by biological, sociodemographic, health sector, and food industry factors?

Breast-feeding duration has important effects on a wide array of demographic and maternal and infant health outcomes. This study uses a discrete-time logit hazards model to explore the relationship of biological, sociodemographic, health sector, and food industry practices on the duration of full and partial breast-feeding in a sample of more than 2,600 infants from the Cebu Longitudinal Health and Nutrition Survey. Food industry and health sector practices (such as distribution of free samples of infant formula), the mother's perception of being pregnant, infant fatness, and a set of standard sociodemographic factors all affect breast-feeding duration significantly.
