Soybeans Consumption and Production in China

China is the world's top consumer and largest importer of soybeans used as human food and livestock feed. Since the 1980s, China's meat consumption has been growing despite this being an inefficient way of feeding the world's largest population. It diverts resources which can be used directly for human consumption. If the Chinese people were to maintain or expand their high consumption of soybean-based foods instead of switching to a meat-rich diet, greenhouse gas emissions would be reduced, and natural resource use improved. This chapter examines the trends in soy consumption and production in China and explores people's dietary preferences for soybeans, including concerns about the import of genetically modified soybeans. Without diverting soybeans to animal feed, the demand for them will decrease and will make China more self-sufficient. This study also provides educational guidance about the health benefits of plant-based foods and environmental damage associated with high consumption of animal-based products.

Comparison of Various Soybean Allergen Levels in Genetically and Non-Genetically Modified Soybeans

Several analyses of allergen levels have been reported as part of the safety assessment of genetically modified (GM) soybean; however, few comprehensive analyses have included new allergens. Thus, in this study the levels of eight major soybean allergens, including Gly m 7 (a newly reported soybean allergen), were semi-quantitatively detected in six GM soybeans and six non-GM soybeans using antigen-immobilized ELISA and immunoblotting. We also analyzed the IgE-reactivity to these soybeans through immunoblotting, using sera from three soybean-allergic patients. The results showed that there were no significant differences in the levels of the major soybean allergens in the GM and non-GM soybeans. Moreover, there were no significant differences in the serum IgE-reactive protein profiles of the patients, as analyzed using immunoblotting. These results indicate that, in general, CP4-EPSPS-transfected GM soybeans are not more allergenic than non-GM soybeans.
