BACKGROUND AND AIMS: Poor dietary intake is commonly associated with malnutrition in the dialysis population and oral nutritional supplementation is strategized to redress dietary inadequacy. Knowledge on clinical efficacy of whey protein supplementation (WPS) as an option to treat malnutrition in continuous ambulatory peritoneal dialysis (CAPD) patients is limited. METHODS: This multicenter, parallel, open-label, randomized controlled trial investigated the clinical efficacy of WPS in 126 malnourished CAPD patients with serum albumin <40 g/L and body mass index (BMI) <24 kg/m2 ...

BACKGROUND & AIMS: Oral intake is diminished immediately after ICU discharge, yet factors affecting nutritional intake after hospital discharge have not been evaluated. The aim of this study was to evaluate dietary intake and factors which may influence intake - appetite and gastric emptying - 3-months after ICU discharge. METHODS: Inception cohort study with ICU survivors compared to healthy subjects. Following an overnight fast, all participants consumed a standardized carbohydrate drink, containing 13 C-octanoic acid, to measure gastric emptying...

BACKGROUND/OBJECTIVES: Spendthrift vs. thrifty individuals expend more energy and experience greater weight loss during caloric restriction (CR). Adaptive mechanisms in skeletal muscle, adipose tissue, and on hormone level modulate energy expenditure (EE) during weight loss. Metabolic mechanisms underlying the variability in EE during CR are unclear. The present study explored whether during long-term CR (i) gene expression changes in skeletal muscle and adipose tissue relate with the individual EE response and weight loss, and (ii) altered catecholamine and FGF21-concentrations are associated with measures of metabolic adaptation...

BACKGROUND/OBJECTIVES: Individuals with high pre-treatment bacterial Prevotella-to-Bacteroides (P/B) ratio have been reported to lose more body weight on diets high in fiber than subjects with a low P/B ratio. Therefore, the aim of the present study was to examine potential differences in dietary weight loss responses between participants with low and high P/B. SUBJECTS/METHODS: Eighty overweight participants were randomized (52 completed) to a 500 kcal/d energy deficit diet with a macronutrient composition of 30 energy percentage (E%) fat, 52 E% carbohydrate and 18 E% protein either high (≈1500 mg calcium/day) or low ( ≤ 600 mg calcium/day) in dairy products for 24 weeks...

BACKGROUND: Adaptive responses to nutrient limitation involve mutations that increase the efficiency of usage or uptake of the limiting nutrient. However, starvation of different nutrients has contrasting effects on physiology, resulting in different evolutionary responses. Most studies performed to understand these evolutionary responses have focused only on macronutrient limitation. Hence our understanding of adaptation under limitation of other forms of nutrients is limited. In this study, we compared the evolutionary response in populations evolving under growth-limiting conditions for a macronutrient and a major cation...

Oocytes are remarkable cells in the matter of accumulating macronutrients. Oviparous animals have evolved to produce germline cells that not only enter meiosis to generate a gamete, but also differentiate into a giant cell designed to support embryo growth. To accomplish that, an oocyte typically grows up to 5,000x its original size by accumulating macromolecules, which are collectively referred to as yolk. This article is protected by copyright.

Rice crop is highly susceptible to the toxic levels of lead (Pb) during early growth stages. Moreover, a sufficient availability of mineral nutrients is critical for survival of plants particularly under stressful conditions. An experiment was carried out to unravel the coordinated effects of Pb stress (1-mM PbCl2 ) and different nutrient treatments (sufficient nutrient supply, nitrogen (N) deprivation, phosphorus (P) deprivation, and potassium (K) deprivation) on morphological growth, reactive oxygen species (ROS), antioxidants, and nutrient status in primed and non-primed rice seedlings...

Dogs and cats make short-term food choices based on palatability. We hypothesized that if palatability were masked, long-term food choices would be based on physiologic requirements, and circulating metabolite concentrations would reflect those choices. Four experimental foods with similar palatability, but varying in macronutrient composition, were prepared for healthy adult dogs (n=17) and cats (n=27). Food 1 was high protein; Food 2 was high fat; Food 3 was high carbohydrates; and Food 4 was balanced for macronutrients...

Obesity is a result of positive energy balance. The aim of this study was to measure (in crossover trials) the energy expenditure and oxidation of glucose and lipids, both at the fasting state and after an intake of meals with a varying macronutrient content, in normal-weight and overweight/obese people. In the study, 46 healthy adult males (23 with normal body weight and 23 overweight/obese), aged 21⁻58, were examined. During two consecutive visits, subjects received isocaloric standardized meals (450 kcal) with different content of basic nutrients...

Background : Iron deficiency is a public health problem in many low- and middle-income countries. Introduction of agro-industrial food by-products, as additional source of nutrients, could help alleviate this micronutrient deficiency, provide alternative sources of nutrients and calories in developed countries, and be a partial solution for disposal of agro-industry by-products. Methods : The aim of this study was to determine iron bioavailability of 5 by-products from Brazilian agro-industry (peels from cucumber, pumpkin, and jackfruit, cupuaçu seed peel, and rice bran), using the in vitro digestion/ Caco-2 cell model; with Caco-2 cell ferritin formation as a surrogate marker of iron bioavailability...

One of the most fundamental behaviors in all the organisms, in order to achieve a satiated state and internal energy homeostasis is feeding. The action of feeding in any being whether be it any vertebrate or an invertebrate involves the perception of the external environment along with the gamut of decision making processes to eat or to not eat. The feeding decision along with chemosensation through gustation and olfaction leads to intake of food with proper nutrient balance along with avoidance of bitter and toxic substances...

Evidence suggests that both high and low birth weight children have increased the risk for obesity and the metabolic syndrome in adulthood. Previously we have found altered feeding behaviour and food preferences in pre-school children and adults born with low birth weight. In this study, we investigated if birth weight was associated with different intake of fat, carbohydrate and/or protein at 6-12 years of age. This is a cross-sectional study where 255 guardians answered online and telephone questions including anthropometrics and demographic data, parental family food rules (food control, encouragement and restriction) and a complete web-based FFQ for their children (130 boys and 125 girls)...

AIM OF THE STUDY: The regulation and actions of fibroblast growth factor 21 (FGF21) are responsive to energy status and macronutrient balance, and investigations of FGF21 in normal pregnancy, which could be informative for FGF21 biology, are seldom. The goal of our study was to examine FGF21 levels in a contemporary healthy, pregnant population. METHODS: We phenotyped 43 women with overweight and obesity during pregnancy for weight, body composition, and fasting blood...

Phosphorus (P) is an essential macronutrient for plant life, although it is frequently not readily available to crops. Arbuscular mycorrhiza fungi (AMF) can improve plant P levels by inducing the expression of some phosphate (Pi) transporters. Symbiotic Pi uptake by Pi transporters is crucial for AMF colonization and arbuscule dynamics. However, the functions of mycorrhiza-inducible maize Pi transporters are largely unclear. We focused on the interaction between the Pi concentration and AMF colonization in maize, and detecting the induction of Pi transporter...

Potassium (K+) is a major macronutrient required for plant growth. In response to low- K+ condition, an adaptive mechanism entails activation of the Ca2+ signaling network consisting of calcineurin B-like proteins (CBLs) and their interacting kinases (CIPKs) in plants. The CBL-interacting protein kinase 9 (CIPK9) is previously implicated in low-K+ responses in Arabidopsis thaliana. Here, we report a protein phosphatase 2C (PP2C), AP2C1, as an interactor of CIPK9. Fluorescence resonance energy transfer (FRET), bimolecular fluorescence complementation (BiFC) and co-localization analyses revealed that CIPK9 and AP2C1 interact in the cytoplasm...

The relationship of CCND2 gene variation, rs11063069 with metabolic syndrome (MetS) modulates by dietary factors but enough data are not available on this issue. So, the hypothesis, which assumes that dietary factors modulate the relationship of CCND2 polymorphisms with the risk of MetS was investigated in our study. Subjects of this nested case-control study were selected from participants of the Tehran Lipid and Glucose Study. Each case (n=974) was pair-matched individually with a control by age, sex and the follow-up duration...

Human intestinal microbes participate actively at the interface of diet, nutrition, and overall health status. These biodiverse communities of microorganisms have a broader metabolic repertoire compared with their host, and they are able to synthesize and degrade substrates that would be otherwise unavailable. In recent years, we have recognized that healthy microbial communities are important for energy harvest and the regulation of body systems outside the digestive tract. Microbial dysbiosis, however, has been implicated in a number of human disorders, including obesity and inflammation...
