Abstract: This work focuses on the design, validation, and evaluation of a nutrition focused website developed to improve nutrition knowledge among adolescents aged 17 to 18 years. Adolescence is a sensitive stage for shaping long term dietary habits, yet many individuals in this age group continue to follow unhealthy eating patterns that increase future health risks. To address this gap, a mobile responsive website titled Nutribook was created using standard web technologies and evidence based nutrition guidelines, with content tailored to common adolescent nutrition concerns. The website included interactive features such as a BMI calculator, sample meal plans, and educational videos presented in simple, age appropriate language. Content accuracy, usability, and educational value were validated by a panel of dietitians, nutrition faculty members, and postgraduate interns. Effectiveness was assessed using a comparative pre test and post test design among 63 adolescents over three months. Statistical analysis showed a marked improvement in nutrition knowledge across all assessed topics, with mean scores increasing significantly after exposure to the website. Expert feedback highlighted overall usefulness while also pointing to areas for refinement in presentation and depth. The findings demonstrate that a well structured digital platform can serve as a practical and effective tool for adolescent nutrition education and support broader efforts to promote healthy dietary behaviours through accessible technology.
