background: an important issue the world faces today is ensuring that households living in different countries have access to enough food to maintain a healthy life. food insecurity is prevalent in both developed and developing countries. the objective of this study was to assess the household food security status and related factors among different rural districts of neyshabur (a city in north...

conclusions the findings of this study offer information regarding the current dietary patterns among adolescent girls that can be used to design educational programs to promote healthy eating in this group. objectives the objective of this study was to examine the food consumption patterns of and obesity in female adolescents in khorramshahr high schools. materials and methods this cross-secti...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...

Four Saudi Arabian indigenous sheep populations including Najdi, Hbsi, Arb, and Naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (FAO). This study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. All loci were polymorphic in all populations and loc...

Food webs are networks of species that feed on each other. The role that within-population phenotypic and genetic variation plays in food web structure is largely unknown. Here, I show via simulation how variation in two key traits, growth rates and phenology, by influencing the variability of body sizes present through time, can potentially affect several structural parameters in the direction...

Since the introduction of genetically modified (GM) plants, one of the main concerns has been their potential effect on non-target insects. Many studies have looked at GM plant effects on single non-target herbivore species or on simple herbivore-natural enemy food chains. Agro-ecosystems, however, are characterized by numerous insect species which are involved in complex interactions, forming ...

The ability of many bacteria to adhere to surfaces and to form biofilms has major implications in a variety of industries including the food industry, where biofilms create a persistent source of contamination. It is reported that biofilms are more resistant to antimicrobials compared to planktonic cells. The colonization of bacteria on the food processing surfaces and even the food structure, ...

Food losses refer to edible food mass decrease throughout the human food chain. Food losses occurring at consumption stage are called food waste. Food Losses and Waste (FLW) represent one of the most critical social, economic and ecological challenges facing humanity, besides being also an ethical issue. FAO data show that roughly one-third of food produced for human consumption is lost or wast...

Food webs-networks of predators and prey-have long been known to exhibit "intervality": species can generally be ordered along a single axis in such a way that the prey of any given predator tend to lie on unbroken compact intervals. Although the meaning of this axis-usually identified with a "niche" dimension-has remained a mystery, it is assumed to lie at the basis of the highly non-trivial s...
