Public nutrition is related to the improvement of population health and the development of social economy. Nutrition and health survey can provide indispensable information for public health and disease prevention and control to improve people's nutritional and health status and support the policy making of food production and chronic diseases prevention and control. In recent years, China's nutritional supply capacity has increased significantly. Our people's nutritional and health status has improved significantly. The articles published in "Nutrition and Health Survey" column come from nutrition surveys both at the national and provincial level. They are making full use of data to give information on not only nutritional and health status of residents throughout the country, but also regional features. These results will provide a detailed and reliable reference for both national and regional nutrition and health policy and strategy making. At present, China's nutrition work faces many challenges. China's Party Central Committee and the State Council always places great emphasis on people's nutritional and health status. In order to promote the health of the whole population in our country, our government has implemented a number of nutrition promotion policies or strategies. Chinese nutrition and health survey will further evaluate the effect of these movements.
