Nutrition plays a critical role in human growth, development, and overall health, with dietary patterns during adolescence influencing long-term well-being and risk of chronic diseases. University and polytechnic students are particularly vulnerable to poor dietary habits due to irregular eating schedules, economic constraints, and reliance on convenient, low-nutrient foods. This study evaluated the energy and nutrient intake of thirty (15 male and 15 female) polytechnic students over a four-day period, including three weekdays and one weekend day. Food and drink consumption data were recorded and analyzed using Microdiet software, with nutrient and energy values compared to Dietary Reference Values. Findings highlight discrepancies between perceived and actual dietary adequacy, emphasizing the need for targeted nutrition education and interventions to promote healthy eating habits and optimize academic performance, cognitive function, and overall health among students.
