For the proper control and analysis of this study, the authors of this paper have chosen these indicators: supply, distribution, consumption, utilization efficiency, food security results, stability, sustainability and controllability. Results indicate that China's food security is currently at a high level and has been increasing in recent years. China's food security has multiple advantages with various indicators that include a self-sufficiency ratio, per capita calorie intake and protein supply that are above world average levels, even exceeding the average level of some developed countries. Major challenges facing China's food security include an unreasonable nutrition structure and poor environmental sustainability. In order to increase China's food security level, efforts must be made to adjust output structure, adopt an environmentally friendly pattern of production, attach importance to demand management, reduce unreasonable consumption and loss and moderately lower China's food reserve ratio.展开更多

In Mexico, the "charal" fish Chirostoma spp. is grouped in five species: Chirostoma grandocule, Chirostoma patzcuaro, Chirostoma humboltianum, Chirostoma attenuatum and Chirostomajordani which live in lakes in the country, and they are not consumed or their demand is low The objective of this research was to analyze the macronutrients of Chirostomajordani charal and inform population their nutritional value to increase human nutrition. Sampling was provided at Xochimilco channels in Xochimilco, D.F., summer and winter seasons at 2009. Fish (200 g) were maintained in channels water for proximal analysis according AOAC methods (1995). The results in dry bases were: protein 74.36%, lipids 1.24%, fiber 0.27%, minerals 4.9%, and soluble carbohydrates 19.23%. This fish grants protein, plastic material essential for human development: its lipid and carbohydrate contents, sources of energy, are low; however, the excess of disseminated proteins increase the energy sources. Fiber is found in a minimum amount. Dehydrated charales may be stored without refrigeration up to 3 months, maintaining their nutritional value. Consumption of the charal should be considered in the basic diet for its nutritional properties, to diminish malnutrition in the Mexico and other countries.展开更多
