“…However, due to the difference in life cycle boundaries and calculation methods, CF values vary significantly for the same kind of food. The CFs of nineteen kinds of CR foods including grains, beans, and root and tuber foods from cultivation to manufacture in China were investigated by Xu et al [34] according to the life cycle assessment (LCA) method. Coarse foods, such as avenanuda, an important part of Chinese diets, were also examined in their research.…”

“…where GHG t is the sum of carbon emissions embedded in CR foods (kgCO 2 eq); X i is the estimated consumption amount of food i per day (kg); and CF i is the CF of food i, which is calculated by Xu et al [34]. The diet should be constrained by the following limitations:…”

“…G1 foods produced most of the total emissions. Xu et al [34] showed that a higher consumption choice of brown rice and standard grade flour could reduce carbon emissions. However, the total consumption of G1 foods was much higher than the upper limit.…”

“…Wheat flour and rice represent most of the CR foods consumed, which is not in line with the principle of Chinese dietary guidelines, i.e., encouraging people to eat diverse foods. Rice and wheat flour showed the highest carbon footprint (CF) among CR foods [34]. Consumers' desire for healthy food can help achieve a diet with low carbon emissions.…”

Background: Carbohydrate-rich (CR) foods are essential parts of the Chinese diet. However, CR foods are often given less attention than animal-based foods. The objectives of this study were to analyze the carbon emissions caused by CR foods and to generate sustainable diets with low climate impact and adequate nutrients. Methods: Twelve common CR food consumption records from 4857 individuals were analyzed using K-means clustering algorithms. Furthermore, linear programming was used to generate optimized diets. Results: Total carbon emissions by CR foods was 683.38g CO2eq per day per capita, accounting for an annual total of 341.9Mt CO2eq. All individuals were ultimately divided into eight clusters, and none of the popular clusters were low carbon or nutrient sufficient. Optimized diets could reduce about 40% of carbon emissions compared to the average current diet. However, significant structural differences exist between the current diet and optimized diets. Conclusions: To reduce carbon emissions from the food chain, CR foods should be a research focus. Current Chinese diets need a big change to achieve positive environmental and health goals. The reduction of rice and wheat-based foods and an increase of bean foods were the focus of structural dietary change in CR food consumption.

Riceberry rice has a special characteristic of being specially bred with high nutrients. High-value added products from riceberry are being promoted targeting health-conscious consumers. To provide supporting information for sustainable food systems, environmental footprinting was applied for evaluating the environmental performance of a ready-to-eat product of riceberry rice mixed with kidney red bean called “Riceberry + KU”, developed by Kasetsart University in Thailand. Based on sold unit as the unit of analysis, the carbon footprint of Riceberry + KU was 5.24 gCO2e per 300 g. Interestingly, white rice had the highest carbon footprint and riceberry rice as well as the riceberry product had at least 30% lower values. However, using nutrient-based scores, although white rice still had the highest carbon footprint, Riceberry + KU had 80% lower and the riceberry rice had 65% lower values. This resulted from the highest nutritional levels found in Riceberry + KU along with the lower greenhouse gas emissions from riceberry field during the cultivation stage. Similar trends were found in the other impact categories assessed by using life cycle assessment as well. To provide appropriate information to consumers for making more sustainable food choices, the environmental performance based on nutrient quality resulting from different farming systems and processing methods should be used to derive recommendations for moving toward sustainable food systems. The nutrition-environment nexus assessment could be very useful for supporting consumers toward making more sustainable food choices.
