During fall migration many songbirds switch from consuming primarily insects to consuming mostly fruit. Fruits with more carbohydrates and less protein may be sufficient to rebuild expended fat stores, but such fruits may be inadequate to replace catabolized protein. We manipulated the concentrations and isotopic signatures of macronutrients in diets fed to birds to study the effects of diet qu...

RATIONALE The eco-physiological mechanisms that govern the incorporation and routing of macronutrients from dietary sources into consumer tissues determine the efficacy of stable isotope analysis (SIA) for studying animal foraging ecology. We document how changes in the relative amounts of dietary proteins and lipids affect the metabolic routing of these macronutrients and the consequent effect...

OBJECTIVE To determine the nutrient intakes and status of preschool children from a representative population sample in Adelaide. DESIGN, SETTING AND PARTICIPANTS Cross-sectional survey of children aged 1-5 years, using a stratified random sampling method and a doorknocking strategy, between September 2005 and July 2007. MAIN OUTCOME MEASURES Dietary intake, assessed using a 3-day weighed-f...

background: sound nutrition is very important in relationship with weight status especially in children. the aim of this study was to assess relationship between junk foods intake and weight in children aged 6-7. methods: this cross-sectional study was carried out in shahin shahr and meimeh in 2009. anthropometric measures were taken and 24-hour food recall was used for dietary data and were an...

Few data are available regarding dietary habits of the elderly, in particular about fatty acid consumption, whereas these are major risk or protective factors of several age-related diseases. The aim of the present study was to characterise the dietary intake of a French elderly population in terms of energy, macronutrients and fatty acids based on their socio-demographic characteristics. The s...

Introduction: Ramadan is the holiest month in Islamic calendar and Muslims abstain from eating, drinking, and smoking from dawn to sunset, in which there are changes in quality of food and eating patterns. The purpose of this study was to know whether these changes provide nutritional needs, and supply all of necessary macronutrients for individuals in the month. Method: A prospective observati...

A study was designed to know the dietary management and to compare the actual intake of macronutrients with the recommended intake of the hospitalized cardiovascular disease patients at Rehman Medical Institute, Peshawar, Pakistan. A sample of 101 CVD hospitalized patients was selected by using convenient sampling method. Questionnaire regarding clinical, biochemical, dietary, family history, d...

Diet is a major modifiable lifestyle factor that may affect the components of the metabolic syndrome. We aimed to investigate the association between relative proportions of macronutrients and the components of the metabolic syndrome in a population of individuals with type 1 diabetes. In all, 791 individuals without nephropathy, with plausible energy intake and known metabolic syndrome status,...

The teaching and research tool called 'DietPLUS', developed by the present author at an institution of higher learning in 2007, contains nutrient information of 840 food items in Excel format. DietPLUS functions as a '2-in-1' food composition database plus a rapid calculator of nutrient intakes, with the option of 'collapsing' the food composition face leaving only the nutrient calculator face....
