Television viewing may contribute to obesity via promotion of sedentary behavior and exposure to food-related commercials. However, the mechanisms by which food-related commercials promote food intake are not well understood. Therefore, the purpose of the present study was to examine the impact of television advertisements on food intake according to sex and transportability, or the tendency to become engrossed in what one is viewing. Eighty-three undergraduate students, free of disordered eating symptoms, were stratified by sex and randomly assigned to one of three conditions (food-related advertisements, neutral advertisements, or no advertisements). They were then identified as high or low in transportability according to a median split. A significant interaction was found between advertisement condition and transportability such that those high in transportability ate more in the food than other advertisement conditions. A second interaction was found between sex and transportability with women high in transportability eating more food than women low in transportability irrespective of advertisement condition. No significant main effects of advertisement condition, sex, or transportability were found. Results suggest the importance of studying the impact of individual difference variables on the relationship between food-related advertising and food intake. HubMed – eating

Positive Attitude toward Healthy Eating Predicts Higher Diet Quality at All Cost Levels of Supermarkets.

Shopping at low-cost supermarkets has been associated with higher obesity rates. This study examined whether attitudes toward healthy eating are independently associated with diet quality among shoppers at low-cost, medium-cost, and high-cost supermarkets. Data on socioeconomic status (SES), attitudes toward healthy eating, and supermarket choice were collected using a telephone survey of a representative sample of adult residents of King County, WA. Dietary intake data were based on a food frequency questionnaire. Thirteen supermarket chains were stratified into three categories: low, medium, and high cost, based on a market basket of 100 commonly eaten foods. Diet-quality measures were energy density, mean adequacy ratio, and total servings of fruits and vegetables. The analytical sample consisted of 963 adults. Multivariable regressions with robust standard error examined relations between diet quality, supermarket type, attitudes, and SES. Shopping at higher-cost supermarkets was associated with higher-quality diets. These associations persisted after adjusting for SES, but were eliminated after taking attitudinal measures into account. Supermarket shoppers with positive attitudes toward healthy eating had equally higher-quality diets, even if they shopped at low-, medium-, or high-cost supermarkets, independent of SES and other covariates. These findings imply that shopping at low-cost supermarkets does not prevent consumers from having high-quality diets, as long as they attach importance to good nutrition. Promoting nutrition-education strategies among supermarkets, particularly those catering to low-income groups, can help to improve diet quality. HubMed – eating

Academy of Nutrition and Dietetics Benchmarks for Nutrition in Child Care 2011: Are Child-Care Providers across Contexts Meeting Recommendations?

Dev DA, McBride BA,

The Academy of Nutrition and Dietetics (Academy) recommends feeding practices for child-care providers to establish nutrition habits in early childhood to prevent obesity. With >12 million US children in child care, little is known about child-care providers’ feeding practices. The purpose of this study was to examine child-care providers’ feeding practices to assess whether providers met the Academy’s benchmarks and whether attainment of benchmarks varied across child-care contexts (Head Start, Child and Adult Care Food Program [CACFP], and non-CACFP). Cross-sectional data was collected in 2011 and 2012 from 118 child-care providers who completed self-administered surveys regarding their feeding practices for 2- to 5-year-old children. ?(2) tests and analysis of variance were used to determine variation across contexts. Head Start providers sat more frequently with children during meals (P=0.01), ate the same foods as children (P=0.001), and served meals family style (P<0.0001) more often compared with CACFP and non-CACFP providers. Head Start providers (P=0.002), parents (P=0.001), and children (P=0.01) received more nutrition-education opportunities compared with CACFP and non-CACFP. Head Start providers encouraged more balance and variety of foods (P<0.05), offered healthier foods (P<0.05), modeled healthy eating (P<0.001), and taught children about nutrition (P<0.001) compared with CACFP and non-CACFP providers. Providers across all three contexts used significantly more non-internal than internal mealtime verbal comments (P<0.0001). Head Start providers had greater compliance with the Academy's benchmarks compared with CACFP and non-CACFP providers. Possible reasons for this compliance might be attributed to Head Start nutrition performance standards and increased nutrition-training opportunities for Head Start staff. Head Start programs can serve as a model in implementing the Academy's benchmarks. HubMed – eating

Effects of hot boning and moisture enhancement on the eating quality of cull cow beef.

Meat Sci. 2013 Jul 17; 96(1): 237-246
Pivotto LM, Campbell CP, Swanson K, Mandell IB

The effects of chilling method and moisture enhancement were examined for improving eating quality of semimembranosus (SM) and longissimus lumborum (LL) from 62 cull beef cows. Chilling method included hot boning muscles after 45 to 60min postmortem or conventional chilling for 24h. Moisture enhancement included 1) a non-injected control (CONT) or injection processing (10% of product weight) using 2) Sodium Tripolyphosphate/salt (Na/STP), 3) Sodium Citrate (NaCIT), 4) Calcium Ascorbate (CaASC), or 5) Citrus Juices (CITRUS). Chilling method by moisture enhancement treatment interactions (P<0.09) were due to decreased hue, chroma and sarcomere length values in hot boned vs. conventionally chilled product (SM and LL) for CaASC vs. other moisture enhancement treatments. Chilling method by moisture enhancement treatment interactions (P<0.05) were due to decreased shear force and increased tenderness in conventionally chilled vs. hot boned LL using CaASC vs. Na/STP. Moisture enhancement can improve tenderness of cull cow beef depending on combinations of chilling method and moisture enhancement treatments used. HubMed – eating

Environmental Factors That Impact the Eating Behaviors of Low-Income African American Adolescents in Baltimore City.

To understand environmental factors influencing the food-related habits of low-income urban African American adolescents.Qualitative research was conducted between February and April, 2010, using in-depth interviews, focus groups, and direct observation.The study was conducted in low-income, predominantly African American neighborhoods of Baltimore City.A total of 20 adolescents were interviewed in 18 in-depth interviews (n = 13) and 2 focus groups (n = 7). Participants were recruited from Baltimore City recreation centers and were eligible if they were African American and aged 10-16 years.The food-related habits of low-income, African American, urban adolescents and reported perceptions of their food environments.Interviews were audio recorded, transcribed, coded, and analyzed for emerging themes.Six thematic categories emerged and were organized into 4 environmental contexts: the neighborhood context (accessibility of food and safety of neighborhood), the school context (school food environment), the family context (family health history, role modeling, and monitoring) and the peer context (peer behaviors).Future efforts to reduce the obesity epidemic among low-income African American adolescents should address the social environment of the family; however, positive behavior change may not be sustainable without neighborhood or school food environment modifications.
