The objective was to determine if individuals could plan a diet that met the Dietary Guidelines (DG) using MyPlate as a guide. Participants (n=73) were 38.9±17.0 years of age, with 97% being Non-Hispanic White, 95% having some college education, and Body Mass Index (BMI) of 26.7±5.9. Participants used MyPlate to plan a one-day menu using food models. Nutrition literacy, nutrition scanning behavior, and nutrition information-seeking experience were assessed. Menus were analyzed using Nutrition Data Systems for Research and were compared to individualized DG recommendations. A multiple linear regression examined what characteristics predicted energy difference scores (difference between energy from menu and DG). Participant menus were lower in energy, grains, and dairy; and higher in fruits and vegetables than DGs (p < 0.001). The regression model was significant (R2=0.24; p < 0.01) with sex (B=-386.92; p < 0.05), BMI (B=29.29; p < 0.05) with nutrition information-seeking experience (B=44.90; p < 0.05) predicting energy difference score. Being male, having a higher BMI, and experiencing more frustration during nutrition informationseeking were associated with higher energy difference scores. It was challenging for this sample of well-educated individuals to make food selections that met the DGs.

AbstractDespite several restrictions to their use, neonicotinoid insecticides are still widely employed worldwide. Residual sub-lethal amounts of these chemicals can have detrimental effects on the behavior of non-target insects. Toxic effects on economically important species such as bees have been widely documented, but less is known about their toxic action on other social insects, such as ants. In this study, we assessed the effect of different sub-lethal doses of the neonicotinoid imidacloprid on the ability of colonies of the invasive ant Lasius neglectus to select the most profitable resource. We used Y-shaped mazes having an imidacloprid-polluted or an unpolluted sucrose solution on the two branches. Two sucrose (0.1 M, 0.5 M) and two imidacloprid (1 μg/ml, 10 μg/ml) concentrations were used. In parallel, we evaluated the marking activity of foragers who fed on the same solutions. We found that the 0.1 M sugar solution polluted with 1 μg/ml imidacloprid was significantly more frequently selected in binary choices experiments than the unpolluted resource. Moreover, the ingestion of the same combination of sugar and imidacloprid significantly increased the marking rate of foragers. The higher concentration of the pollutant had lower effects, probably because of the hormesis phenomenon. Results suggest that the lower sub-lethal dose of imidacloprid can lead ants to select again the polluted resource. This "active" selection of the pollutant may magnify the negative effects on the colonies. Due to their ecological role, any impairment of ant survival or behavior may have detrimental cascade effects on the whole ecosystem.

A colony site occupied by grey-headed flying-foxes (Pteropus poliocephalus) from October to May on
the central coast of N.S.W. was monitored over a 48 month period (1986-1990). Faecal and spat-out
material was collected for microscopic determination of contents. Comparison of food items in the
droppings with the array of possible food sources present in the vicinity of the colony at the same time
showed a marked preference for certain foods, in particular blossoms of the family Myrtaceae and of
the genus Banksia. Cultivated orchard fruits were not a preferred food and were only taken at times
when preferred food items were scarce.

The National School Lunch Program (NSLP) is a federal program that provides free and reduced priced lunch to millions of low-income children in urban schools. Empirical research shows mixed results on the physical and nutritional health of urban students participating in the program. However, a considerable limitation of this literature is that it focuses on student participation in the NSLP rather than what students consume when they receive a school lunch. By directly collecting a random of sample of school lunches, we analyze the nutritional content of both selected and consumed school lunches ( n = 141) at a Title I middle school in a large US city. Results indicated that the food items that students select for school lunch are low in nutrients and high in sugar. Furthermore, food that students ultimately consumed during lunch had even lower nutritional value while consumption of sugar remained high. Future research is needed to investigate school-based interventions that leaders can deploy to foster healthy eating in urban schools.

The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two‐thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information‐acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies.

Risky Foods, Safer Choices confirms what many people may have suspected - the incidence of food poisoning is on the rise. Triggering such public suspicions has been an ongoing procession of horror incidents involving such foods as salami, oysters, pork rolls, fruit salad and even orange juice that have resulted in the serious illness and even death of consumers. Risky Foods, Safer Choices helps consumers avoid the possibly tragic consequences of food poisoning. Its focus is on relatively short-term health effects of good food selection rather than longer-term health effects
