OBJECTIVE To establish the feasibility and utility of a simple data collection methodology for dietary assessment. DESIGN Using a cross-sectional design, trained data collectors approached adults (approximately 20 - 40 years of age) at local grocery stores and asked whether they would volunteer their grocery receipts and answer a few questions for a small stipend (dollar 1). METHODS The gro...

There is a growing consensus that our food-rich living environment contributes to rising numbers of people with overweight and obesity. Low-cost, effective intervention tools are needed to facilitate healthy eating behavior, especially when eating away from home. Therefore, we present a field experiment in a restaurant that tested whether providing subtle environmental diet reminders increases ...

Negative mood often triggers binge eating in bulimia nervosa (BN). We investigated motivational salience as a possible underlying mechanism using event-related potentials (ERPs) indicators of motivated attention allocation (P300) and sustained processing (LPP). collected ERPs (P300: 350–400 ms; LPP: 600–1000 ms) from 21 women with full-syndrome or partially remitted BN healthy (HC), matched for...

The present study was designed to investigate the representation of calorie levels in space. Previously an association between numerical magnitude and space has been established, namely, Spatial Numerical Association Response Codes (SNARC) effect. spatial-numerical reveals smaller larger numbers by left right sides, respectively. In addition, previous studies showed that spatial arrangement foo...

BACKGROUND AND OBJECTIVES Financial limitations in low-income populations, those at highest risk for poor health outcomes, may preclude adherence to recommended dietary guidelines. We examine the financial burden of shopping for foods to meet national dietary recommendations in a supermarket compared to eating primarily in a fast-food restaurant. METHODS Using a single-parent, low-income mode...

OBJECTIVES To test whether increased television viewing is associated with increased total energy intake and with increased consumption of foods commonly advertised on television, and to test whether increased consumption of these foods mediates the relationship between television viewing and total energy intake. DESIGN Prospective observational study with baseline (fall 1995) and follow-up (...

Prevailing thinking about obesity and related diseases holds that quantifying calories should be a principal concern and target for intervention. Part of this thinking is that consumed calories – regardless of their sources – are equivalent; i.e. ‘a calorie is a calorie’. The present commentary discusses various problems with the idea that ‘a calorie is a calorie’ and with a primarily quantitat...

INTRODUCTION The obesity epidemic has drawn attention to food marketing practices that may increase the likelihood of caloric overconsumption and weight gain. We explored the associations of discounted prices on supermarket purchases of selected high-calorie foods (HCF) and more healthful, low-calorie foods (LCF) by a demographic group at high risk of obesity. METHODS Our mixed methods design...

OBJECTIVE To assess the overall diet quality of a sample of adolescents living in Alberta, Canada, and evaluate whether diet quality, nutrient intakes, meal behaviours (i.e. meal skipping and consuming meals away from home) and physical activity are related. DESIGN A cross-sectional study design. Students completed the self-administered Web-Survey of Physical Activity and Nutrition (Web-SPAN)...

abstract objective: gestational diabetes mellitus (gdm) is characterized by glucose intolerance during pregnancy. incidence of gestational diabetes can increase by several factors such as obesity, aging, diet and genetic factors. this study aimed to assess the role of nutrition, biochemical and demographic factors in development of gdm in pregnant women. materials and methods: in this prospecti...
