Developments in poultry nutrition have generally been driven by the need to sustain genetic potential within the confines of ever evolving systems of poultry production. Over the last 50 years we have developed quite sophisticated systems for quantitating the available nutrients in both ingredients and diets and this has allowed us to provide birds with quite precise levels of nutrients require...

OBJECTIVE We aimed to assess the relative validity and reproducibility of a semi-quantitative FFQ in Puerto Rican adults. DESIGN Participants completed an FFQ, followed by a 6 d food record and a second administration of the FFQ, 30 d later. All nutrients were log transformed and adjusted for energy intake. Statistical analyses included correlations, paired t tests, cross-classification and B...

OBJECTIVE To develop a worked example of product reformulation of a very popular 'junk food' to meet nutritional guidelines for public health in a ready meal. DESIGN Indicative survey of popular Margherita pizzas, followed by product reformulation, applying dietary guidelines to generate a single-item pizza meal containing 30 % daily amounts of energy and all nutrients. An iterative process w...

in order to evaluate the quantitative factors in fox tail millet (setaria italica l.) under three stages of growth, an experiment was conducted in birjand during spring and summer of 2010. the preliminary objective was evaluation of fox tail physiological characteristics on animals that feed them. planting of foxtail millet was performed according to local practices and endemic acknowledge. sam...

Objective: To describe the methodology used to clean up and estimate dietary intake (DI) data from the Semi-Quantitative Food Frequency Questionnaire (SFFQ) of the Mexican National Health and Nutrition Survey 2012. Materials and methods: DI was collected through a shortterm SFFQ regarding 140 foods (from October 2011 to May 2012). Energy and nutrient intake was calculated according to a nutri...

based on the date obtained through food consumption surveys conducted by the institute of nutrition and food technology research (during 1991-95), the dietary quality of seven provinces (eastern azerbaijan, isfahan, tehran, khorasan, khouzestan, sistan-baluchestan and fars) was assessed. using allowances figures for developing countries, single value nutrient density (s.v.n.a.) was designed for...

This paper reviews published data that contributes to the knowledge of the ingredients and nutrients of Cameroon traditional dishes. Macronutrient (energy, carbohydrates, protein, total fat, fibre and ash) and mineral (iron, zinc, magnesium, calcium, phosphorus, copper, manganese, potassium, sodium and selenium) data are presented for 117 commonly consumed dishes from three eco-regions. Tables ...

UNLABELLED The effect of energy, protein, fat, and phenylalanine on serum phenylalanine concentrations during pregnancy for a set of identical twins with phenylketonuria (PKU) was examined. Blood samples were collected one to two times per week. The subjects completed a 3-d food record prior to each blood collection. The effect of the factors on serum phenylalanine levels was evaluated statisti...

The objective of this study was to assess the environmental impact of a submerged anaerobic MBR (SAnMBR) system in the treatment of urban wastewater at different temperatures: ambient temperature (20 and 33°C), and a controlled temperature (33°C). To this end, an overall energy balance (OEB) and life cycle assessment (LCA), both based on real process data, were carried out. Four factors were co...
