Foodservice systems refer to the complex network of planning, preparing, delivering, and serving meals in large-scale institutions such as hospitals, schools, universities, and restaurants. These systems aim to provide safe, nutritious, and cost-effective meals to meet the needs of diverse populations. Research in this field focuses on optimizing foodservice operations for efficiency, sustainability, and nutritional quality. For example, studies may explore how food sourcing, meal planning, and preparation techniques can impact the nutritional value of the meals served. Moreover, foodservice systems research includes evaluating the environmental impacts of these operations, such as food waste and the carbon footprint of supply chains. Implementing innovative strategies like sustainable sourcing, waste reduction, and menu optimization can enhance the nutritional quality of food served while reducing environmental impacts. A well-functioning foodservice system is essential for promoting healthy eating in controlled environments where meals are a critical component of daily nutrition.
