We investigated the effects of soil nutrient and water availability on the growth and chemistry of the silky willow ( Salix sericea Marshall), and on the performance of the imported willow leaf beetle ( Plagiodera versicolora Laichartig). Our major aims were to determine whether there are nutrient–water interactions on plant traits and whether this leads to parallel interactions for herbivore p...

OBJECTIVE To examine changes in the Na content of lunch/dinner menu offerings at eight of the leading fast-food restaurants in the USA between 1997/1998 and 2009/2010. DESIGN Menu offerings and nutrient composition information for the menu items were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center (NCC) Food and Nutrient Database. Nutrient composit...

The framework ecological stoichiometry uses elemental composition of species to make predictions about growth and competitive ability in defined elemental supply conditions. Although intraspecific differences in stoichiometry have been observed, we have yet to understand the mechanisms generating and maintaining such variation. We used variation in phosphorus (P) content within a Daphnia specie...

INTRODUCTION The purpose of this study was to determine if the nutrient content of recipes available in newspapers is related to community obesity rates. METHODS All recipes published in the major newspapers for 3 cities with populations of 400,000 or more from 4 geographic areas within the United States the last week of August 2000 were accessed. The recipes were grouped as entree, dessert, ...

OBJECTIVE To describe the dietary composition of the New Nordic Diet (NND) and to compare it with the Nordic Nutrition Recommendations (NNR)/Danish Food-based Dietary Guidelines (DFDG) and with the average Danish diet. DESIGN Dietary components with clear health-promoting properties included in the DFDG were included in the NND in amounts at least equivalent to those prescribed by the DFDG. T...

The inmates of prisons are restricted to a rigid diet which they are unable to vary or supplement, and upon which they may have to subsist for long periods of time. It is therefore of cardinal importance that the diet scales provided for them should be nutritionally adequate in every respect. There are numerous historical reports of malnutrition occurring in prisons. Between 1939 and 1944 it wa...

BACKGROUND Snacking raises concern since it may lead to an additional energy intake and poor nutrient quality. A snacking occasion can be defined as any eating occasion apart from main meals, regardless of the amount or type of foods consumed. We described the frequency of snacking occasions according to daily timing in French adults, and compared them between each other, and with the main meal...
