Background: Contents of breast milk may change during the first weeks after childbirth, especially in preterm deliveries. The present study aimed to determine the macronutrient contents of breast milk in the mothers with preterm delivery. Methods: This prospective-descriptive study was conducted in Mahdieh Hospital in Tehran, Iran in 2015. Participants included the mothers with preterm deliver...

Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different locations even during a meal. We hypothesized that lambs forage at locations containing foods that complemen...

The biological differences between males and females are determined by a different set of genes and by a different reactivity to environmental stimuli, including the diet, in general. These differences are further emphasized and driven by the exposure to a different hormone flux throughout the life. These differences have not been taken into appropriate consideration by the scientific community...

For centuries the concept of energy balance has provided the bedrock for research into the mechanisms controlling body weight. However, in recent years there has been growing interest in the regulation of the individual macronutrients that combine to determine the energy status of an individual. Thus the classical energy balance equation can be more accurately represented as the integrated sum ...

Background Currently, the ISSN recommends 50-80 kcal/kg/day for strength athletes participating in intense training. In addition to caloric recommendations, other macronutrient recommendations include protein, carbohydrate and fat, 1.5-2.0 g/kg bodyweight, 5-8 g/kg bodyweight, and 30% of total calories respectively. Athletes participating in collegiate club sports may not have the benefit of ob...

BACKGROUND Little is known about the genes influencing dietary energy and nutrient intakes, despite evidence that these intakes are influenced by genetic factors. OBJECTIVE We aimed to identify, by using a genome-wide linkage analysis, chromosomal regions harboring genes that affect energy and macronutrient intakes. DESIGN Energy, carbohydrate, lipid, and protein intakes were assessed in 83...

BACKGROUND/OBJECTIVES Breast milk is the best available food for optimum growth and development of infants and the breastfeeding rate is increasing in Korea. The purpose of this study is to measure the concentrations of macronutrients and to evaluate their changes according to lactation period in breast milk from lactating Korean women. SUBJECTS/METHODS Milk samples were obtained from 2,632 h...

Extreme macronutrient intakes possibly lead to different brain signalling. The aim of the present study was to determine the effects of ingesting high-protein v. high-carbohydrate food on liking and wanting task-related brain signalling (TRS) and subsequent macronutrient intake. A total of thirty female subjects (21.6 (SD 2.2) years, BMI 25.0 (SD 3.7) kg/m²) completed four functional MRI scans:...
