This paper presents a behavioral economics model with bounded rationality to describe an individual's food consumption choices that lead to weight gain and dieting. Using a physiological relationship determining calories needed to maintain weight, we simulate the food consumption choices of a representative female over a 30-year period. Results show an individual will periodically choose to diet, but that diet will reduce weight only temporarily. Recurrence of weight gain leads to cyclical dieting, which reduces the trend rate of weight increase. Dieting frequency is shown to depend on decision period length, dieting costs, and habit persistence.

Diet therapy or nutritional therapy has become a real challenge in the fight against the increasing number of modern illnesses such as obesity, diabetes, cardiovascular diseases and cancers. The scientific community has recognized the importance of studies that will support or rebut the association of certain nutrition/energy inputs with the prevention and/or improvement of certain diseases. Patient counseling is offered by medical doctors, nutritionists and dieticians, but patients often seek additional sources of information from popular media that may not be adequately scientifically supported. Whose responsibility is it when the Diet Therapy is not an effective treatment and where does the consequent ethical and moral responsibility lie?

This chapter argues for the importance of a nutritionally educated scientist evaluating the diets that are seen to be related with the health improvement also excluding diets that are mostly related to the patients’ well-being as the Mediterranean, DASH (Dietary Approaches to Stop Hypertension), Ketogenic and Vegetarian diet. Diet guidelines are often explained with linguistic variables (as “reduce the input of” etc.) which can be differently perceived by the end user. The interpretation if a linguistic variable is presented using the body mass index categories using a bell-shaped curve. The preferable area fits to the linguistic variable “acceptable BMI.” But also are indicated those areas which are less preferable. Those examples of information interpretations show the necessity of knowledge transfer. The quantity of information presented in diet guidelines can be experienced as a great muddle for patients; leaving them not knowing where and how to start. So, remains the ethical and moral responsibility of all links in the chain of nutritional and diet research and recommendations. Only objective and open-minded recommendations based on the latest scientific facts can gain confidence of the social, economical, and political subjects which must put the well-being of the population uppermost in their mind.

The chapter is an auto-ethnographic account of the self-management of a chronic illness within the context of a participatory research project on Mediterranean Diet (MD). A group of Italian women with type 2 diabetes is following a non-medical, personal interpretation of the Mediterranean-style diet. The research account is preceded by a critical appraisal of the scientific narratives of the MD.

Analysis of epidemiological research on MD examines some methodological aspects of gender blindness in its scientific approach. The ethnography concerns self-management of MD diet and redefinition of gender relations.

MD is analyzed as a case of transplantation of yesterday’s cultural and social capitals of the peasant classes, to today’s discourses on food considered as appropriate for affluent people suffering from satiety diseases. The ethnography highlights gender aspects of biographical work, examining in particular a “conversion” dietary model.

The ethnography must be amplified to include women and men from different social classes with various Mediterranean cooking habits, and family and gender patterns.

The chapter highlights cultural processes for women’s empowerment in self-managing type 2 diabetes.

This chapter may represent a seminal sociological work on chronic illness, gender and food studies in one of the “native” contexts of the Mediterranean-style diet.

In this chapter the aim is to analyse the way the relationship between health and food has been changing at the same time as Spanish society itself. From the beginnings of the consumer society until the present day the modernization process has made its imprint on the guidelines public bodies have issued to the public on caring for their health and diet. Beginning in the 1960s with a welfare idea of a healthy diet, very typical of the decade, and meant for a population with nutritional problems, today we have guidelines for an overfed population. The social trends dominant in each historical moment are shown throughout this transformation process and the dietary recommendations have been part of the social change. However, the perceptions of the administration itself on what constitutes a healthy diet have also made their mark on the criteria. The modernizing nature of the paternalistic administration of the 1960s can be easily seen in contrast with the public bodies of the 1980s competing with the messages from the food and agricultural businesses. As the 20th century drew to a close, dietary advice was in keeping with a background dominated by considerations on the nature of social change and in which both public bodies and citizens trusted in the truths of science as a reference point for correct action. At the beginning of the 21st century, reflexivity and questioning of scientific power appear and also an increase in public preoccupation with food risks. Each stage is analysed relating historical background and dietary recommendations.

The treatment and care of persons with a disability should and must be all encompassing. With the expansion of the knowledge that proper dieting can make a difference in the individual’s development and quality of life, attention must be focused on using proper food intake to remediate the negative impact of a disability. Food is related to proper healthcare; therefore, we must include proper nutrition in working with learners with exceptionalities. We must add to the list of treatments not only educational intervention, social interaction, and independent living, but also food intake. This chapter looks at the dietary needs of several disabling conditions, and addresses how particular dietary food selections help in their development and their ability to learn integration, playing skills with others, and working independently when called on to do so. Therefore, for the purposes of this chapter, we focus on exceptionalities such as cognitive disability, autism spectrum disorder (ASD), Down syndrome, attention deficit hyperactivity disorder (ADHD), muscular dystrophy, and cystic fibrosis.

Social scientists often speculate that both acculturation and socioeconomic status are factors that may explain differences in the body weight between Mexican Americans and whites and between Mexican Americans and Mexican immigrants, yet prior research has not explicitly theorized and tested the pathways that lead both of these upstream factors to contribute to ethnic/nativity disparities in weight. We make this contribution to the literature by developing a conceptual model drawing from Glass and McAtee’s (2006) risk regulation framework. We test this model by analyzing data from the 1999–2012 National Health and Nutrition Examination Survey (NHANES). Our conceptual model treats acculturation and socioeconomic status as risk regulators, or social factors that place individuals in positions where they are at risk for health risk behaviors that negatively influence health outcomes. We specifically argue that acculturation and low socioeconomic status contribute to less healthy diets, lower physical activity, and chronic stress, which then increases the risk of weight gain. We further contend that pathways from ethnicity/nativity and through acculturation and socioeconomic status likely explain disparities in weight gain between Mexican Americans and whites and between Mexican immigrants and whites. Study results largely support our conceptual model and have implications for thinking about solutions for reducing ethnic/nativity disparities in weight.

Improving the nutritious quality of diets for individuals and populations is a central goal of many public health advocates and intergovernmental organizations. Yet the outcome of healthy eating has been shown to systematically vary across individual-level socioeconomic lines, and across countries in different locations of the food system. We therefore assess variation in the association between eating nutritionally dense fresh fruits and vegetables and both self-rated health (SRH) and body mass index (BMI) across individual income and country locations in the food system.

We use nationally representative survey data from 31 countries drawn from the International Social Survey Programme’s 2011 Health module. We estimate the effect of the frequency of eating fresh fruits and vegetables using random-intercept, random-coefficient multilevel mixed-effects regression models.

We confirm that eating nutritionally dense fresh fruits and vegetables frequently associates with more positive health outcomes. However, this general conclusion masks substantial individual- and country-level heterogeneity. For both SRH and BMI, the largest beneficial associations are concentrated among the most affluent individuals in the most affluent countries. Moving away from either reduces the positive association of healthy eating.

Our results provide an important wrinkle for policies aimed at changing the nutritional quality of diets. Adjustments to diets without taking into account fundamental causes of socioeconomic status will likely be met with attenuated results.

We compare two important health outcomes across a wide variety of types of countries. We demonstrate that our main conclusions are only detectable when employing a flexible multilevel methodological design.

The purpose of this analysis is to determine the impact of various factors, including population growth, income growth, and research and development on food security. This chapter also seeks to better understand the role of relative food prices in consumers’ selection of foods to meet their nutritional needs.

We utilize a welfare economic framework to provide a theoretical examination of the impact of various factors (including income growth, population growth, and research and development) on food security among the poor. A minimum nutritional diet is specified as a baseline for the evaluation of these scenarios.

Scenarios show the impacts that income, population growth, and research and development have on food security through their price and quantity impacts. Also, we highlight the difficulty in formulating an optimal diet that meets the recommended dietary requirements for only calories and protein, as different foods contain calories, proteins, and micronutrients in differing proportions. This indicates that changes in relative food prices will often alter consumers’ nutrient intake with respect to the minimum nutritional diet.

Research and development is critical in guaranteeing food availability. Trade-based, production-based, and own-labor entitlements are key factors in determining food security. Consumption subsidies and income supplements can be used to assist those who do not have entitlements sufficient to meet their minimum nutritional diet.

The residents of Ambridge enjoy a varied and mostly nutritious diet ranging from a ploughman’s at The Bull to Jennifer Aldridge’s roast venison, with the occasional tofu and quinoa paella from Kate Madikane. For Helen Titchener (née Archer) an abrupt change in circumstances will have led to changes in her diet that could have endangered her health and that of her unborn baby. Helen was imprisoned from about eight months of pregnancy to about four months postpartum, encompassing a critical period in development of her baby. This chapter focusses on the case of Helen and her baby son Jack to explore the dietary requirements for pregnancy and breastfeeding and how these relate to diet in Ambridge and in prison.
