Nutritional factors and nutritional deficiencies have been repeatedly associated with cognitive impairment. Most of the evidence is based on cross-sectional studies, which cannot prove whether a nutritional deficit is the cause or the consequence of an impaired cognitive status. In fact, cognitive impairment, in turn, can determine changes in dietary habits and consequent nutritional deficienci...

Six measures of nutritional status were studied in 162 consecutive cases of presumed nutritional keratopathy ranging from mild xerosis through full-thickness necrosis (keratomalacia) and in a variety of control subjects. The severity of corneal involvement was related to the severity of wasting, prevalence of edema, and serum levels of albumin, transferrin, and vitamin A. Even the most sever...

For ruminants, the microbial population existing in the rumen breaks down feed ingredients offered to the animal. This population must be healthy and viable to permit maximum utilization of feed ingredients. Because ruminants evolved mainly as forage feeders, factors that disrupt population of cellulolytic microorganisms will result in reduced utilization of nutrients -primarily, energy and pro...

Grain legumes, such as soybean (Glycine max (L.) Merr.), pea (Pisum sativum L.), faba bean (Vicia faba L.), lupins (Lupinus spp.), common vetch (Vicia sativa L.) and grass pea (Lathyrus sativus L.), represent one of the most quality and least expensive solutions for a long-term demand for plant protein in animal husbandry. One of the limitations to an increased use of grain legumes as feed is t...

In recent years our knowledge of the formation, nutrition and metabolism of the cells of the blood has been greatly advanced by studies with the electron microscope, from tagging various nutrients and precursors with radioactive tracers, by advances in staining methods, by the use of specific enzymes to attack substances in particular regions of cells and of absorption-spectra techniques and va...

Adolescent have typically been considered as low risk for poor health and often receive few health care resource and attention. However, their approach ignores the fact that many health problems later in life can be improved by adopting health life style habits in adolescents. There is a shortage of studies about nutritional status and associated factors among adolescent girls. The objective of...

Introduction: Identifying factors influencing infants' anthroponmetric indices is very important in improving maternal and neonatal health levels. The present analytical discriptive study has been done to determine the significant factors affecting the nutritional status of infants in Bojnord. Method: In this servey done in 2001 a total number of 566 infants and their mothers were studied. The ...

Introduction: A challenge for health care providers is that there will be a distinct rise globally in the number of elderly people aged 80 years and over. Malnutrition is a well-known problem among elderly people. The aim of this study was to determine nutritional status and its associated risk factors in elderly nursing home residents in Tehran, Iran.  Methods: The cross-sectional st...

Introduction: The future success of the beef industry will be largely determined by our ability to meet consumer demands. Consumers want beef to be safe, consistently tender, palatable, free of outside fat, easy to prepare, and reasonably priced compared to other proteins. The dramatic increase in the number of cattle marketed through grid pricing structures is an example of the beef industry r...
