Alternate lunch patterns in high schools. III. Food acceptability

Area of Science:

• Nutrition Science
• Food Service Management
• Public Health

Background:

• School lunch programs aim to provide nutritious meals to students.
• Plate waste in school lunches is a significant concern, impacting resource efficiency and food security.
• Traditional menu planning may not align with student preferences, leading to substantial food waste.

Purpose of the Study:

• To evaluate the impact of different menu planning methods on food acceptability and plate waste in high school lunches.
• To compare the effectiveness of a free-choice menu pattern versus traditional methods in reducing food waste.
• To analyze gender-based differences in food waste within school lunch programs.

Main Methods:

• A study was conducted in 48 high schools involving alternate methods of menu planning for school lunches.
• Food acceptability and plate waste were systematically assessed for different menu patterns.
• Data on total plate waste, categorized by food type (e.g., vegetables, salads), were collected and analyzed.
• Gender-specific food waste data were recorded and compared.

Main Results:

• The free-choice menu pattern led to a significant reduction in total plate waste compared to other methods.
• Waste reduction was particularly notable in the vegetable and salad categories.
• Girls consistently demonstrated higher levels of plate waste than boys across all menu patterns.
• Overall plate waste percentages were 7% for boys and 13% for girls.

Conclusions:

• Implementing a free-choice lunch menu is an effective strategy for reducing overall plate waste in school settings.
• This menu approach is particularly beneficial for minimizing waste of less popular or poorly consumed food items.
• Addressing gender-specific differences in food waste may require tailored interventions within school nutrition programs.
