We investigated the effect of the parasitic mite Varroa destructor on the immunological and nutritional condition of honey bees, Apis mellifera, from the perspective of the individual bee and the colony. Pupae, newly-emerged adults and foraging adults were sampled from honey bee colonies at one site in S. Texas, USA. Varroa‑infested bees displayed elevated titer of Deformed Wing Virus (DWV), su...

OBJECTIVE To evaluate the iron nutritional status of children from 6 to 59 months of age and its relation to vitamin A deficiency. METHOD Cross-sectional study involving 100 children, living in nine cities in the state of Paraíba, which were selected for convenience to form two study groups: children with vitamin A deficiency (serum retinol < 0.70 μmol/L; n = 50) and children without vitamin ...

Rice weevil (Sitophilus oryzae L.) is a primary insect pest of stored grain. The development of resistance resulted in the application of synthetic insecticides. In recent years many plant essential oils have provided potential alternatives to currently used insect control agents. The Brazilian pepper tree (Schinus molle L. var. areira (L.) DC.) (Anacardiaceae) has different biological properti...

BACKGROUND This paper analyzes the role of child, maternal and household variables on weight-for-age nutritional status of children in the largest urban slum of Bangladesh. METHODS We use anthropometric weight-for-age nutrition status of children for an ordered logistic analysis. Our dataset gives us the advantage of segregating health knowledge into three indices: health-seeking practices in...

BACKGROUND Prices are an important determinant of food choices. Consequently, food price policies (subsidies and/or taxes) are proposed to improve the nutritional quality of diets. The aim of the present study was to explore the impact of food price policies on the expenditures and nutritional quality of the food baskets chosen by low- and medium-income households. METHODS Experimental econom...

Background: Food prices influence food choices. Purchasing foods with higher nutritional quality for their price may help improve the diet quality of socioeconomically disadvantaged individuals. Objective: This study aimed to describe the co-construction and evaluation of the Opticourses prevention program, which promotes healthy eating among participants in socioeconomically deprived situation...

In this chapter we have reviewed the evidence for physiological anorexia of aging and stressed that its pathophysiology involves both central and peripheral mechanisms. Early satiation in the older person appears to involve signals predominantly arising in the stomach. The increased feeling of satiety in older persons is mainly related to changes in the central feeding drive, in particular a de...

BACKGROUND Non-pharmacological measures are recommended for heart failure patients. However, most studies evaluate low sodium diet, while little is known about the effects of interventions to improve adherence and knowledge of patients about diet content. OBJECTIVE To evaluate if a global nutritional orientation could affect nutritional knowledge, adherence to food guidelines, anthropometrics...

Promotion of healthy eating is an effective public health strategy to prevent chronic disease incidence and progression. However, food prices can impede healthy eating, especially in rural communities. The purpose of this study was to determine whether food costs are associated with nutritional quality, geographic location, and month of year. The Overall Nutritional Quality Index and cost of 92...

little scientific information is available that has evaluated safflower (carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. the objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (tmrs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. two consecutive trials were conducted us...
