Chinese Food Image Database for Eating and Appetite Studies

Area of Science:

• Psychology
• Nutrition Science
• Cultural Studies

Background:

• Ubiquitous food cues impact eating behavior, necessitating relevant research materials.
• Existing food image databases lack suitability for Chinese dietary contexts.
• Diet is critical for health, driving extensive research into eating behaviors.

Purpose of the Study:

• To develop a comprehensive library of Chinese food images for research.
• To investigate factors influencing dietary decision-making using these images.
• To provide a valuable data reference for future food image-based studies.

Main Methods:

• Selection and standardization of 508 common Chinese food images.
• Detailed classification of images by taste, nutrients, calories, and emotional response.
• Examination of variables like income, BMI, and eating styles on food choices.

Main Results:

• Household income significantly affects dietary decision-making: taste preference for low income, health consciousness for high income.
• Parental BMI is linked to children's food choices, with higher parental BMI correlating with lower perceived food healthiness.
• Individual perceived healthiness and palatability are key dependent variables in food choices.

Conclusions:

• The developed Chinese food image library is a valuable resource for behavioral and nutritional research.
• Socioeconomic factors, particularly income, play a significant role in shaping food preferences and choices.
• Family health indicators, like parental BMI, can influence children's dietary habits and perceptions of healthy eating.
