Abstract
China's rapid economic growth has led to a significant increase in the number of people who are eating away from home. However, some studies show that increased meat consumption poses a health burden while others show dietary diversity promoted by away from home enhances health. As a result, the effects of away from home on dietary nutritional quality remain inconclusive. Moreover, estimates of total food consumption are underestimated without considering away from home. Herein, we constructed away from home models (R2 = 0.59) to assess its impacts on the quantity and quality of food consumption. By 2020, away from home accounted for 18% (233.37 g) of total consumption in urban areas and 8% (81.80 g) in rural areas. Although, at the national scale, away from home consumption of meat, poultry, and aquatic products led to decreased dietary nutritional quality in urban areas from 2000 to 2020 and in rural areas since 2015, by 2020, three urban provinces and 12 rural provinces still showed improvements in dietary nutritional quality from such consumption. Additionally, overall dietary nutritional quality of away from home impact in urban areas improved from 2000 to 2015 but decreased in 2020, whereas rural areas saw consistent improvement across all years, suggesting the divergent impacts on diet nutrition quality across urban and rural China. Our findings underscore the urgency and necessity of extensively strengthening national nutritional education and developing specific nutrition-health policies tailored to economic conditions. This study also provides critical data for accurate food consumption and life cycle evaluations, promoting sustainability in the food system.
期刊介绍：
Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches.
Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet.
From this perspective, the journal covers the following areas:
Global food needs: the mismatch between population and the ability to provide adequate nutrition
Global food potential and global food production
Natural constraints to satisfying global food needs:
§ Climate, climate variability, and climate change
§ Desertification and flooding
§ Natural disasters
§ Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production
§ Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production
The sociological contexts of food production, access, quality, and consumption.
Nutrition, food quality and food safety.
Socio-political factors that impinge on the ability to satisfy global food needs:
§ Land, agricultural and food policy
§ International relations and trade
§ Access to food
§ Financial policy
§ Wars and ethnic unrest
Research policies and priorities to ensure food security in its various dimensions.
