This cross-sectional descriptive research aimed to study nutritional literacy, fast food consumption behavior, and the relationship between nutritional literacy and fast food consumption behavior among high school students in a school in Mueang Chaiyaphum District, Chaiyaphum Province. The study sample consisted of 185 students selected through cluster sampling. Data were collected using a questionnaire. The reliability of the nutritional literacy questionnaire and the fast food consumption behavior questionnaire were test with Cronbach's alpha coefficient, which was found to be 0.89 and 0.92, respectively and analyzed using descriptive statistics, including frequency distribution, percentage, mean, standard deviation, and inferential statistics, including Spearman’s Rank Correlation Coefficient (r_s) and 95% confidence interval.

The study results showed that the majority of the sample were female (65.95%) and aged between 15-18 years. Most students had a moderate level of nutritional literacy (57.30%, 95% CI: 49.83-64.53), followed by a good level (25.40%, 95% CI: 19.30-32.31). Regarding fast food consumption behavior, most students exhibited a moderate level (85.41%, 95% CI: 79.48-90.16), followed by a good level (11.89%, 95% CI: 7.60-17.45), with an average behavior score of 2.93 (standard deviation = 0.29). Regarding the relationship between nutritional literacy and fast food consumption behavior among high school students in a school in Mueang Chaiyaphum District, Chaiyaphum Province, The study found that access to nutritional information, decision-making in food selection, and overall nutritional were found to have a statistically significant low positive correlation with fast food consumption behavior (r_s = 0.27, p-value <0.001; r_s = 0.21, p = 0.005; r_s = 0.19, p = 0.011). However, knowledge and understanding of food consumption as well as media literacy in nutrition were not significantly correlated with fast food consumption behavior. (r_s = 0.018, p = 0.813; r_s = 0.061, p = 0.409, respectively)

Programs should be developed to promote nutritional literacy that emphasizes translating knowledge into practice, coupled with creating environments conducive to healthy food choices, and encouraging family involvement in raising awareness about good nutrition.
