Dietary behavior is a fundamental determinant of physical, psychological, and social health during youth. The transition from adolescence to young adulthood is often accompanied by substantial lifestyle changes that influence food choices, meal frequency, and nutritional quality. Increasing academic commitments, changing social environments, easy access to processed foods, and irregular daily routines have contributed to unhealthy eating habits among many young adults. These dietary changes may affect not only physical health but also perceived well-being and overall quality of life. The present study examined the association between dietary patterns and self-reported well-being among youth. A quantitative cross-sectional research design was adopted, and data were collected from 220 young adults using a structured questionnaire. Descriptive statistics, Pearson correlation, and multiple regression analysis were employed to examine the relationship between dietary behaviors and perceived well-being. The findings revealed that healthy dietary practices, including regular breakfast consumption, higher intake of fruits and vegetables, balanced meals, adequate hydration, and greater dietary diversity, were positively associated with improved physical health, emotional stability, and overall well-being. Conversely, frequent consumption of fast foods, processed snacks, sugar-sweetened beverages, and irregular meal patterns showed negative associations with perceived health outcomes. The study emphasizes the importance of promoting healthy eating behaviors through nutrition education and campus-based health promotion initiatives. Encouraging sustainable dietary practices among youth may contribute significantly to improving both immediate well-being and long-term health outcomes.
