Major nutrients in the Type A lunch. II. Amounts consumed by students

Area of Science:

• Nutrition Science
• Public Health
• Pediatric Nutrition

Background:

• School lunch programs are crucial for student nutrient intake.
• Understanding nutrient waste in school lunches informs dietary recommendations.

Purpose of the Study:

• To assess nutrient consumption and plate waste in Type A school lunches.
• To identify differences in nutrient intake by grade level and geographic region.

Main Methods:

• Collected plate waste from Type A lunches in North Carolina schools.
• Analyzed nutrients in meals served and plate waste via laboratory analysis.
• Calculated nutrient consumption by subtracting waste from served nutrients.

Main Results:

• Fifth graders consumed a significantly lower percentage of served nutrients compared to seventh and tenth graders.
• Protein intake met goals; riboflavin and vitamin A were satisfactory.
• Ascorbic acid intake was least satisfactory for fifth and seventh graders.
• High school students consumed 69% of iron and 75% of energy goals.
• Eastern region elementary students consumed a higher percentage of served nutrients.

Conclusions:

• Nutrient waste in school lunches varies by grade level and nutrient type.
• Targeted interventions may be needed to improve nutrient consumption, especially for younger students.
• Regional differences in nutrient consumption highlight the need for localized strategies.
