AIMS: One of the most important factors affecting physical performance and performance of job duties in military students is diet and its content. This study aimed to compare the content of the diet and Nutritional and physical needs of officer students and provide appropriate Nutritional solutions. MATERIALS & METHODS: The present study is a descriptive-survey study whose population was students of a military university in Tehran, Iran in 2020. 120 people were selected by random sampling. To evaluate the studied variables, food frequency questionnaire FFQ (with 24-hour food recall) and physical activity questionnaire in three days, and N4 Food Processor software was used. The obtained data were analyzed using a t-test in SPSS 20 software at a significance level of less than 0. 05. FINDINGS: The results of the present study showed that the age, height, weight and body mass index of the samples were respectively 21. 36±, 8. 2 years, 169. 64±, 45. 10 cm, 73. 34±, 74. 6 Kg and 25. 47±, 37. 2 Kg/m2. The number of carbohydrate, sodium and fat intake was higher than the amount required by the body, while the amount of protein intake was less than the estimated amount for the students of the officer's university, which was significantly different from the current standard (p=0. 001). Also, the number of received calories, the amount of energy expenditure, vitamin A, vitamin D, vitamin B12, vitamin E, vitamin C, calcium, magnesium, and zinc received by students are statistically and significantly lower than the values of existing standards and the amounts of micronutrients required to perform the activities properly (p=0. 001). CONCLUSION: The student diet needs modifications such as improving the quality and quantity of the diet, adding small snacks, adding dairy products, as well as some fresh fruits and vegetables.
