Our food consumption patterns play a major role in determining both human and planetary health. A substantial body of evidence has shown that the current worldwide food consumption is not only contributing to 19–29% of greenhouse gas (GHG) emissions, but is also responsible for using 37% of the Earth’s landmass.

Furthermore, worldwide rising income and urbanization have contributed to the dietary transition from plant-based products to more animal-based diets, and the category of “meat and meat products” contributes most to the environmental footprint in many parts of the world. The situation is expected to get worse as more populations are experiencing dietary transition, resulting in asymmetrical environmental degradation around the world.

Our study highlighted the importance to better understand the effects of geographical location and related food cultures for reducing the dietary environmental impacts. The present study also indicated that meat was the main source of the dietary environmental footprint in contemporary China, while the over-consumption of meat is severe for all groups of Chinese people.

Reversing this trend in China and other countries, and increasing the consumption of foods that are consistently associated with low environmental impacts, would undoubtedly have multiple environmental benefits. Hence, more interventions that seek to change people’s food consumption behaviors are specifically needed. This will require a better understanding of how individuals’ dietary behaviors are influenced by the interaction effect of economic conditions and dietary cultures within which individuals are embedded, not only in China but also in other countries with diverse food cultures.
