Anemia continues to pose a major public health concern among young adults, often resulting from poor dietary patterns and insufficient awareness. This study was undertaken to evaluate the knowledge, attitude, and practices (KAP) related to healthy dietary behaviors toward anemia among college students in Greater Noida. A descriptive cross-sectional design was employed, involving 210 participants aged 18 to 26 years from various academic disciplines. Data were gathered using structured questionnaires administered both online and offline, encompassing demographic details and questions related to KAP. Statistical analysis was conducted using SPSS version 25.0. Chi-square tests were used to assess associations between variables, and Pearson correlation was applied to explore the relationships between knowledge, attitude, and practice scores. The analysis showed that 76.2% of respondents were female, and 81% were within the 18-23 years age group. Most participants (71.4%) came from science backgrounds, and over half (52.4%) adhered to vegetarian diets. While a large majority recognized iron deficiency (95.2%) and blood testing (97.6%) as key to understanding anemia, fewer students were aware of its hereditary nature (57.1%) and the role of vitamin B12 (61.9%). Though 85.7% acknowledged the need for iron-rich foods and 90.5% emphasized healthy eating, only 57.1% included iron-rich items in their regular diet. Additionally, 28.6% consumed tea or coffee immediately after meals, which may hinder iron absorption. Significant associations were found between knowledge and both academic stream (p = 0.021) and diet type (p = 0.036), while gender showed no significant link (p = 0.089). A positive correlation was observed between knowledge and both attitude (r = 0.362) and practice (r = 0.275). The findings underline the need for targeted nutritional education to close the gap between awareness and practice in anemia prevention.
