Growing global population figures and per-capita incomes imply an increase in food demand and pressure to expand agricultural land. Agricultural expansion into natural ecosystems affects biodiversity and leads to substantial carbon dioxide emissions. Considerable attention has been paid to prospects for increasing food availability, and limiting agricultural expansion, through higher yields on ...

The effects of differences in meal frequency on body weight, body composition, and energy expenditure were studied in mildly food-restricted male rats. Two groups were fed approximately 80% of usual food intake (as periodically determined in a group of ad libitum fed controls) for 131 days. One group received all of its food in 2 meals/day and the other received all of its food in 10-12 meals/d...

tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. human glucose tolerance declines as day comes into night. based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...

food safety issues are not a new issue in science, but due to the dynamic changes in the modern world it is as equally important as decades ago. the aim of the study was to address the efforts in the development of a comprehensive food safety system in serbia, and make specific recommendations regarding the improvement of epidemiological investigation capacity as a useful tool which contributes...

This paper constructs a simple model to illustrate that the current food stamp subsidy scheme fails to achieve its aim due to the crowding-out effect. In particular, if the household income is sufficiently low, only the corner solution exists and full subsidy is needed. The optimal food stamp subsidy scheme is identified and the subsidy efficiency rate is introduced to measure the impact on foo...

Today's agriculture provides an ever increasing population with sufficient quantities of food. During food production, processing, handling and transportation, an amount of energy is invested into the various products. An energy analysis of a typical American diet provides policy makers, farmers and the public with the necessary information to evaluate and make informed decisions as to how to i...

Fast food culture is an emerging trend among the younger generation. The ready availability, taste, low cost, marketing strategies and peer pressure make them popular with children and adolescents. Fast food restaurants are primed to maximize the speed, efficiency and conformity. The menu is kept limited and standardized essentially to minimize the waiting time so that the customers eat quickly...

As the global population continues to grow, food needs will increase as well. The amount of land and other resources devoted to agriculture production is not expected to grow significantly, leading most to agree that the substantial increases in food production to meet food security needs will come through the development of technologies that improve production efficiency. Diseases are constant...
