Research methods that predict Fe bioavailability for humans can be extremely useful in evaluating food fortification strategies, developing Fe-biofortified enhanced staple food crops and assessing the Fe bioavailability of meal plans that include such crops. In this review, research from four recent poultry (Gallus gallus) feeding trials coupled with in vitro analyses of Fe-biofortified crops w...

well known in rats fed similar diets, and that the sample size (six rats) was too small to draw any conclusions. Following the production of the first transgenic plants, health issues The report by Ewen and Pusztai (1999) was seized concerning the safety of using genetically modified (GM) crops in foods and feeds have been discussed, debated, and evaluated. The upon by anti-GM advocates to supp...

Micronutrient deficiencies are a significant cause of malnutrition worldwide, particularly in developing countries, affecting nearly 1.8 billion people worldwide. Agriculture is the primary source nutrients for humans, but increasing population and reducing arable lands areas putting agricultural sector under pressure, less developed calls intensive farming to increase crop yield overcome food ...

The intensification of agriculture has provided cheaper more plentiful food, but has also caused declines in farmland wildlife. The introduction of genetically modified (GM) crops may exacerbate this, or offer new ways of mitigating anthropogenic impacts. The potential consequences of the introduction of GM crops have been studied for over a decade, since commercialization. Although the specifi...

Bemisia tabaci (Gennadius) whiteßy populations produce economically important damage to crops by their direct feeding and also by transmitting plant viruses. Although there are several methods to reduce B. tabaci damage, most growers rely on the use of insecticides to decrease populations of this pest. Insecticides that reduce feeding of whiteßy adults may also reduce the transmission of viruse...

The tobacco whitefly Bemisia tabaci is one of the most devastating pests worldwide. Current management of B. tabaci relies upon the frequent applications of insecticides. In addition to direct mortality by typical acute toxicity (lethal effect), insecticides may also impair various key biological traits of the exposed insects through physiological and behavioral sublethal effects. Identifying a...

OBJECTIVES One means through which children learn eating behaviours is the feeding strategies used by parents. Although research has studied the effects of parental feeding strategies on consumption, choice, and liking, little is known about the goals parents themselves seek. The study aimed to explore the feeding goals sought by parents of preschool children. DESIGN An exploratory qualitativ...

Several lines of evidence suggest that brain histamine may be involved in the central control of food intake. The effect of histamine on feeding is mediated through three kinds of receptors (H1, H2, and H3). The present study was designed to investigate the effect of intracerebroventricular injection of histamine, promethazine (H1 antagonist) and ranitidine (H2 antagonist) on food intake of fre...
