Understanding how energy is utilized by the pig, and how the pig responds to changes in dietary energy concentration, is essential information in determining the optimal concentration of dietary energy under farm conditions, which are often highly diverse. The objective of these experiments was to determine how changes in dietary DE concentration, achieved through graded changes in diet composi...

OBJECTIVE Intake of sugars is restricted in most international food guides. However, in recent recommendations quantified limits of added sugars intake have not been given, although deemed necessary by those who criticised the recommendations. DESIGN Two approaches to derive a scientifically based quantified limit of added sugars intake for German children and adolescents are suggested. For t...

A cross-sectional analytical study was undertaken to describe the nutritional status and dietary intake of the elderly black population of Cape Town. A stratified proportional sample of 148 men and women aged 60 years and older (mean = 68.9+/-5.7) was selected from informal and formal peri-urban settlements. The study population was predominantly urbanized, although most subjects had migrated f...

For nearly three decades, a fundamental objective in the study of plant–herbivore interactions has been to understand why the consumption of a single plant species is rare in mammals, as only a handful of mammalian herbivores (b1%) are dietary specialists. Here, we provide an overview of various factors that may play a role in limiting dietary specialization. We review the energetic consequence...

Because of the suggested role of energy consumption and the well-documented role of estrogens in the etiology of breast cancer, we have examined the effect of a 40% restriction of dietary energy consumption on the ability of administered 17beta-estradiol (E2) to induce mammary tumorigenesis in female ACI rats. Experiments herein test the hypothesis that at least part of the inhibitory effect of...

b a ckground:  obesity is recognized as a major public-health problem, which has reached epidemic proportions, in both developed and developing countries. the purpose  of   this   survey  is   to   study  effects  of   gastric  bypass  surgery  at micronutrients and macronutrients intake on patients with morbid obesity. m et h o ds :   this quasi-experimental study was conducted on 21    patien...

An experiment was carried out to investigate the effects of different dietary levels of energy on growth performance and meat yields of indigenous (desi) chickens up to the target weight of 950 g in rural condition. One hundred indigenous unsexed chicks aged 4 weeks were considered for the feeding trial until the body weight reached at 950g. Chicks were divided into two dietary treatments havin...

This study aimed to investigate the energy metabolism of patients with lung cancer and the relationship between energy metabolism and proinflammatory cytokines. Twenty-eight patients with lung cancer and 18 healthy controls were enrolled in this study. The nutritional status upon admission was analyzed using nutritional screening tools and laboratory tests. The resting energy expenditure and re...

In chronic renal failure (CRF) patients with a reduced protein intake, if the patients' energy intake could be estimated on the basis of biochemical data together with protein intake, it would be easier to provide them with adequate dietary treatment. Thus, from the relationship among the normalized protein catabolic rate (nPCR) and the intrinsic creatinine generation rate (%GCr) both calculate...

a diverse range of foods has been shown to increase energy and micronutrients intake in the developing countries. it is widely asserted in the literature and development circles that farm household access to irrigation dam can provide a significant improvement of household’s dietary diversity. this study set out to assess the role of kampe irrigation dam on farm household dietary diversity in k...
