With the growing interest in studying the characteristics of people's access to the food environment and its influence upon individual health, there has been a focus on assessing individual food exposure based on GPS trajectories. However, existing studies have largely focused on the overall activity space using short-period trajectories, which ignores the complexity of human movements and the heterogeneity of the spaces that are experienced by the individual over daily life schedules. In this study, we propose a novel framework to extract the exposure areas consisting of the localized activity spaces around daily life centers and non-motorized commuting routes from long-term GPS trajectories...

The burden of obesity contributes to increasing health inequality, and placing healthcare systems under huge strain. The modern society could broadly be described to support unhealthful eating patterns and sedentary behaviour; also described as obesogenic. Obesity prevention and treatment has focused on educational and behavioural interventions, with limited overall success. A sustainable approach is to address the environments that promote less healthy eating and high energy intake as well as sedentary behaviour...

The survival strategies of migrant women living in urban poverty are embedded in urban food landscapes ('foodscapes') characterized by dynamic social relationships and mobility. Relying on interviews with 31 migrant women in Washington, DC, this paper traces the socio-spatial conditions of their urban foodscapes to show that urban environments inhabited by low-income migrants are dynamic, stretching across multiple neighborhoods as they move throughout the city with social networks to obtain affordable, quality, and culturally appropriate food...

BACKGROUND: Retail food environments (foodscapes) are a recognised determinant of eating behaviours and may contribute to inequalities in diet. However, findings from studies measuring socioeconomic inequality in the foodscape have been mixed, which may be due to methodological differences. The aim of this cross-sectional study was to compare exposure to the foodscape by socioeconomic position using different measures, to test whether the presence, direction or amplitude of differences was sensitive to the choice of foodscape metric or socioeconomic indicator...

Seasonal changes in the foodscape force herbivores to select different plant species or plant parts to meet nutritional requirements. We examined whether the search for calorie-rich carbohydrates explained giant panda's selection for bamboo culm over leaves during spring. Leaves and culms were collected from four Phyllostachys bamboos (P. aurea, P. aureosulcata, P. glauca, and P. nuda) once per month over 18-27 months. Monthly changes in annual plant part nutrients were examined, and compared to seasonal foraging behaviors of captive giant pandas...

This paper reviews studies of the validity of commercially available business (CAB) data on food establishments ("the foodscape"), offering a meta-analysis of characteristics associated with CAB quality and a case study evaluating the performance of commonly-used validity indicators describing the foodscape. Existing validation studies report a broad range in CAB data quality, although most studies conclude that CAB quality is "moderate" to "substantial". We conclude that current studies may underestimate the quality of CAB data...

Good accessibility to both healthy and unhealthy food outlets is a greater reality than food deserts. Yet, there is a lack of conceptual insights on the contextual factors that push individuals to opt for healthy or unhealthy food outlets when both options are accessible. Our comprehension of foodscape influences on dietary behaviours would benefit from a better understanding of the decision-making process for food outlet choices. In this paper, we build on the fundamental position that outlet choices are conditioned by how much outlets' attributes accommodate individuals' constraints and preferences...

The study was conducted to understand fried-food (FF) consumption among Hispanic Caribbean (HC) communities in New York City. Data were collected through qualitative interviews with 23 adults self-identified as Cuban, Dominican, or Puerto Rican. Most informants considered FFs an important part of their traditional diet. Potential explanations included taste, cost, convenience, and the emotive values attached to FF. FF consumption was contextualized in local foodscapes. Results include strategies to diminish FF consumption and differences across HC groups and migratory generations...

This article examines the way the category of 'the sensorial' is mobilised across obesity research and care practices for overweight persons in France. The 'natural' body is understood to have developed mechanisms that motivate eaters to seek out energy-dense foods, a hardwiring that is maladaptive in today's plethoric food environment. The article analyses the feedback models mobilised in scientific literature on the neuroendocrine processes regulating appetite. The analysis of how 'the sensorial' is studied and used to treat patients provides a vantage point onto the ways foods and bodies transform each other...

ETHNOPHARMACOLOGICAL RELEVANCE: Fermented food and beverages represent an important part of the worldwide foodscape, medicinal food domain and domestic strategies of health care, yet relevant traditional knowledge in Europe is poorly documented. METHODS: Review of primary ethnographic literature, archival sources and a few ad-hoc ethnobotanical field studies in seven selected Eastern European countries (Albania, Belarus, Bulgaria, Estonia, Hungary, Kosovo, and Poland) were conducted...

PURPOSE: The goal was to examine the relationship between the food environment and selected socioeconomic variables and ethnic/racial makeup in the eight largest urban settings in Texas so as to gain a better understanding of the relationships among Hispanic composition, poverty, and urban foodscapes, comparing border to non-border urban environments. METHODS: Census-tract level data on (a) socioeconomic factors, like percentage below the poverty line and number of households on foodstamps, and (b) ethnic variables, like percent of Mexican origin and percent foreign born, were obtained from the U...

In past and contemporary foodscapes, meat and meat products have not only been following convenience trends, they have been at the heart of them. Historically, the first substantial demands for meat convenience must have been for the outsourcing of hunting or domestication, as well as slaughtering activities. In its turn, this prompted concerns for shelf-life stabilisation and the development of preservation strategies, such as meat fermentation. Demands for ease of preparation and consumption can be traced back to Antiquity but have gained in importance over the centuries, especially with the emergence of novel socio-cultural expectations and (perceived) time scarcity...

OBJECTIVE: This paper explores which of absolute (i.e. densities of "healthy" and "unhealthy" food outlets taken separately) or relative (i.e. the percentage of "healthy" outlets) measures of foodscape exposure better predicts fruit and vegetable intake (FVI), and whether those associations are modified by gender and city in Canada. METHODS: Self-reported FVI from participants of four cycles (2007-2010) of the repeated cross-sectional Canadian Community Health Survey living in the five largest metropolitan areas of Canada (n=49,403) was analyzed...

OBJECTIVES: We examined whether access to retail sources of healthy and unhealthy food varies according to level of neighbourhood material deprivation in three Ontario regions and whether urban form characteristics help to explain any such variations. METHODS: Food retail (FR) outlets were identified from a commercial database for 804 urban neighbourhoods in Toronto, Brampton/Mississauga and Hamilton, Ontario. The median number of healthy and unhealthy FR outlets and percentage of outlets that were unhealthy were derived using 720-metre network buffers based on dissemination blocks and aggregated up to neighbourhood level (census tract)...

The aim of this study was to assess the accuracy of self-estimated vegetable and whole grain serving sizes in a self-served buffet meal. The study took place in a laboratory setting where an Intelligent Buffet was used to register the exact weight of each food type that was self-served by each participant. The initial sample consisted of 58 participants recruited from Aalborg University in Copenhagen, of which 52 participants (59% male) provided complete estimates on the weight of whole grains and 49 participants (63% male) provided complete estimates on the weight of vegetable servings in their meal...

"Gluten free" exploded onto the American foodscape in recent years: as of January 2013, 30 percent of U.S. adults reported reducing or eliminating gluten in their diets. How do individuals participate in the expansion of gluten-free dieting, and what are the implications of that expansion? This article is based on 31 in-depth, semi-structured interviews conducted between May and October 2012 with gluten-free and -restricted persons. I identify three interrelated factors contributing to the expansion of gluten-free dieting among non-celiacs...

Adequate nutrition is a fundamental requirement for the maintenance and growth of populations, but complex interactions between nutrients and plant toxins make it difficult to link variation in plant quality to the ecology of wild herbivores. We asked whether a 'foodscape' model of habitat that uses near-infrared spectroscopy to describe the palatability of individual trees in the landscape, predicted the foraging decisions of a mammalian browser, the koala (Phascolarctos cinereus). Specifically, we considered four behavioural decision points at which nutritional quality may influence an animal's decision...

BACKGROUND: The use of Geographical Information Systems (GIS) to objectively measure 'obesogenic' food environment (foodscape) exposure has become common-place. This increase in usage has coincided with the development of a methodologically heterogeneous evidence-base, with subsequent perceived difficulties for inter-study comparability. However, when used together in previous work, different types of food environment metric have often demonstrated some degree of covariance. Differences and similarities between density and proximity metrics, and within methodologically different conceptions of density and proximity metrics need to be better understood...

BACKGROUND: Socio-ecological models of behaviour suggest that dietary behaviours are potentially shaped by exposure to the food environment ('foodscape'). Research on associations between the foodscape and diet and health has largely focussed on foodscapes around the home, despite recognition that non-home environments are likely to be important in a more complete assessment of foodscape exposure. This paper characterises and describes foodscape exposure of different types, at home, at work, and along commuting routes for a sample of working adults in Cambridgeshire, UK...

BACKGROUND: Ethnobotanical surveys of the Western Balkans are important for the cross-cultural study of local plant knowledge and also for obtaining baseline data, which is crucial for fostering future rural development and eco-tourism initiatives in the region. The current ethnobotanical field study was conducted among the last remaining Albanians inhabiting the upper Reka Valley at the base of Mount Korab in the Mavrovo National Park of the Republic of Macedonia.The aims of the study were threefold: 1) to document local knowledge pertaining to plants; 2) to compare these findings with those of an ethnographic account written one century ago and focused on the same territory; and 3) to compare these findings with those of similar field studies previously conducted in other areas of the Balkans...
