This study aimed to examine the motivation and consumption behavior related to healthy food among Generation Z university students in Nakhon Si Thammarat Province. It also explored the relationship between personal factors, motivational drivers, and healthy food consumption behavior. The sample consisted of 400 undergraduate students who had prior experience consuming healthy food. Data were collected using a structured questionnaire and analyzed using descriptive statistics and the Chi-square test. The findings revealed that most respondents were female, enrolled in education-related majors, had a monthly expense of 4,001–6,000 baht, and resided in dormitories or apartments. Overall, respondents reported a high level of motivation toward healthy food consumption. The most prominent push motivation was the desire to maintain good health, while the most significant pull motivation was the appeal of reasonable pricing and high-quality ingredients. In terms of behavior, the majority consumed healthy food two to three days per week, mostly at shopping malls. Online platforms were the primary source of information. The main purposes of consumption were health improvement and physical strength. Cleanliness was identified as the most important factor in choosing healthy food, and yogurt was reported as the most frequently consumed product. Hypothesis testing indicated statistically significant relationships (p < 0.05) between all personal factors and both types of motivation—push and pull—and healthy food consumption behavior. These findings offer practical insights for entrepreneurs and marketers in developing targeted strategies to effectively meet the needs of Generation Z students.
