This study examines the relationship between product healthfulness and firm performance in the South Korean food industry. Using a comprehensive dataset of food companies and their product portfolios, we investigate how health-oriented product strategies impact various dimensions of firm performance, including financial metrics, market positioning, and consumer perception. Our findings provide insights into the business value of health-focused product development strategies.
The Impact of Healthfulness on Firm Performance
The Case of Food Companies in South Korea
Abstract
Research Motivation
🏥 Growing Health Consciousness
The global trend toward health-conscious consumption has fundamentally transformed the food industry landscape:
- Increasing consumer demand for healthier food options
- Rising awareness of diet-related health issues

📈 Business Strategy Question
Despite the apparent consumer preference for healthy foods, the business implications remain unclear:
- Mixed evidence on whether health-focused strategies improve financial performance
- Potential trade-offs between healthfulness and profitability
- Limited understanding of market positioning benefits
- Need for empirical evidence in the Korean market context
