The nutrition facts table is a nutrition labeling tool designed to help consumers understand the nutritional content of food and make informed food choices. However, the utilization rate of the nutrition facts table has been low in China since its introduction in 2013. This study employed structural equation modeling to investigate consumers’ knowledge, attitudes, and practices related to the nutrition facts table by using an online survey of 930 valid samples from 31 provinces in China based on the knowledge, attitude, practice (KAP) model. The analysis revealed that most respondents had a positive attitude, but not a good level of knowledge or practice in their use of the labeling. Respondents’ knowledge about the nutrition facts table directly affected their attitude, through which it could then affect their practice, whereas knowledge played an indirect role in nutrition labeling use. The results confirmed that the KAP model is suitable for explaining consumers’ use of nutrition labels in China, and that the first step to promoting labeling usage is to enrich consumers’ knowledge on the nutrition facts table.

The nutrition facts table is a nutrition labeling tool designed to inform consumers of food nutritional contents and enable them to make healthier choices by comparing the nutritional values of similar foods. However, its adoption level is considerably low in China. This study employed the Chi-squared Automatic Interaction Detection (CHAID) algorithm to explore the factors associated with respondents’ adoption of nutrition facts table to compare the nutritional values of similar foods. Data were gathered through a nationally representative online survey of 1500 samples. Results suggested that consumers’ comprehension of the nutrition facts table was a direct explanatory factor for its use. The usage was also indirectly explained by people’s nutrition knowledge, the usage of nutrition facts table by their relatives and friends, and their focus on a healthy diet. Therefore, to increase the use of nutrition facts table by Chinese consumers, the first consideration should be given to enhancing consumers’ comprehension of the labeling

Objective: We analyzed the impact of nutrition claims on Chinese consumer psychology and behavior process based on the theoretical framework of AISAS (Attention-Interest-Search-Action-Share) model.Design: To adopt questionnaires to collect gender, age, income and other basic information of adult residents and a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree) to collect data on residents’ attention to nutrition claims, interest in nutrition claims, search on nutrition claim information, purchasing behavior on food with nutrition claims, sharing information on food with nutrition claims. Then to study the relationship between the basic situation of residents and their attention, interest, search, food purchase behavior and sharing of nutrition claims by using exploratory factor analysis, reliability and validity test, structural equation modeling estimation and hypothesis testing.Participants: Chinese adults.Setting: Multi-stage stratified random sampling method was used to collect the valid online questionnaire of 630 Chinese adults from Central, North, East, South, Northwest, Southwest, and Northeast China.Results: Younger adults and those with higher household incomes exhibited heightened attention to nutrition claims. Furthermore, consumers’ attention to nutrition claims could be transformed into food information sharing through interest, information search, and food purchase. Consumers’ interest in food with nutrition claims could be transformed directly into food purchase. Consumers’ search for related information could be directly transformed into food information sharing.Conclusion: Chinese consumers’ age and household income could be included in the AISAS model for the foods with nutrition claims, and the consumers’ action and share could transform from their interest and search.

Excessive average daily pork intake of Chinese residents increases the risk of obesity and related chronic diseases. Understanding consumers’ preference for the Front-of-Package (FOP) labeling on fresh pork is of practical significance for designing an FOP labeling scheme that meets market demand and effectively guides moderate pork consumption. This study used the conditional logit model to reveal the stated preferences of 930 nationally representative respondents in China for FOP labeling attributes elicited by a choice experiment approach. The results indicated that respondents preferred the nutritional information to be printed in Chinese characters, the label size to be a quarter of the front package surface, the label color to be green, and the label price to account for 10% of the retail price of 500 g standard fresh pork. Moreover, these preferences were heterogeneous across the sample population due to respondents’ different levels of education and trust in labeling. People with primary and junior high school education preferred nutritional information in Chinese characters, while those with junior high education and above preferred green labeling. The higher the respondents’ trust in the labeling, the stronger their willingness to accept the appropriate FOP labeling price. Information campaigns and educational programs can be used to increase the acceptance of FOP labelling, particularly among consumers with low education levels and distrust of FOP labeling.

The Chinese food industry has opposed the mandatory inclusion of increased nutrients in the Nutrition Facts Table (NFT), thus impeding its improvement. This poses a challenge to the endeavors aiming to assist consumers in cultivating healthy dietary habits that incorporate reduced saturated fatty acids and added sugars while ensuring the adequate intake of essential micronutrients. This study conducted a choice experiment to investigate Chinese consumers’ preference for updated labeling schemes among 630 adults that were randomly selected from Central, North, East, South, Northwest, Southwest, and Northeast China. It revealed that respondents were willing to pay the highest premium for the most mandatory nutrients (22.575% of the food price per unit). Respondents preferred the NFT with the most mandatory nutrients if they met the following population characteristics: female; non-overweight or obese; without a college degree; possessed an annual household disposable income between 50,000 and 99,999 CNY; from North China; lived in rural areas and often cooked for family; cared about food nutrition. Two combinations of NFT information received the highest preference: (1) the NFT detailing the most mandatory nutrients and their content values and nutrient reference values (NRV%); (2) the NFT containing the most nutrients and the nutrients in 100 g/mL or a serving. The first and second combinations attracted a premium of 14.884% and 31.833% of the food price per unit, respectively.

Front of Package (FOP) labeling, which assists consumers in understanding the nutritional status of fresh pork, could help reduce Chinese residents’ excessive meat intake and greenhouse gas emissions. Nevertheless, little is known about the price elasticity of consumers’ demand for the FOP labeling on fresh pork. This study implemented a contingent valuation survey by using a representative survey of 930 adults across China. The results indicated that respondents’ demand for FOP labeling applied to fresh pork was price inelastic (−0.209). Moreover, there existed significant population heterogeneity in the price elasticity of demand. Specifically, WTP increased for the urban population and those who paid regular attention to pork’s nutritional value. Overall, Chinese consumers had rigid demand for FOP labeling on fresh pork, and policy makers should pay close attention to consumer reactions to the price of FOP labeling and promote this application on fresh pork.
