Reproduction is the most energetically costly process that most female mammals ever undergo. When nutritional resources are scarce, and there is a high probability that females will be unable to cope with this energetic challenge, reproductive processes are inhibited. This process is highly conserved and likely adaptive and reversible when nutritional resources become available. Although the nu...

iron deficiency anemia is one of the nutritional problems of the low income, undernourished populations of the world. in iran, many rural and low socioeconomic urban groups suffer from iron deficiency anemia because of a low iron intake and the low level of public health. to overcome and to prevent iron deficiency, a program was suggested to enrich the bread with iron, calcium and some of the b...

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 ...

Collective foraging, based on positive feedback and quorum responses, is believed to improve the foraging efficiency of animals. Nutritional models suggest that social information transfer increases the ability of foragers with closely aligned nutritional needs to find nutrients and maintain a balanced diet. However, whether or not collective foraging is adaptive in a heterogeneous group compos...

Behavioral theories can guide clinicians in developing the best strategies for promoting a therapeutic nutritional change. Commonly utilized behavioral models in nutrition interventions in geriatric populations include the Ecological Perspective, the Health Belief Model, the Stages of Change Model, the Theory of Meaningful Learning, the Information Processing Model, and Social Cognitive Theory....
