With a rapid development of internet and e-commerce market, another emerging trend that should not be overlooked is the change in food shopping habits induced by the popularity of online-to-offline (O2O) food delivery service in China. The O2O food market is a booming industry in China, the market scale of O2O food industry is increasing with remarkable speed. More than 1/5 of total population in China has already became the users of O2O food delivery market. Development of this new trend in food environment is inevitable. This game-changing trend brings great opportunities to improve food accessibility and availability but meanwhile poses inevitable challenges to the whole public health system and social environment in China.
