This study examines the habits of junk food intake among students, emphasizing their knowledge of its detrimental effects and how it relates to particular demographic factors. The study was carried out in Dehradun, Uttarakhand, and employed a quantitative, non-experimental descriptive research approach. It featured semi-structured interviews that were split into two categories: demographic data and the effects of junk food. Results showed that although 98% of students agreed that junk food is unhealthy, there was a substantial knowledge gap, with 38% of students not knowing about the nutritional value and potential health risks. Because of its deliciousness, the majority (70%) ate junk food instead of breakfast. These findings show a worrying trend towards unhealthful food choices driven more by flavor than by nutritional value, highlighting the need for more diet and health education.
