The good health of the body depends on the regular intake of the various nutrients it needs. The work we have done. Given the magnitude of this behavior, including students in our universities, we proposed to conduct a survey of 1744 students of both sexes in 4 Moroccan universities: Rabat, Marrakech, Tangier and Kenitra (Morocco) The results of this survey enabled us to profile the volunteers. Generally, female students are most threatened by malnutrition of certain nutrients, especially vitamins A, D and C and calcium. The prevalence of these students who are in a state of inadequate iron intake which probably exposes them to severe anemia is 54.8%. However, these almost insufficient intakes of these micronutrients make the students enter into a very important psychological stress behavior and especially among the students. Faced with this alarming situation, the authorities are called upon to multiply efforts to cope with this handicap that affects students, especially those who come from far away from the University City. Keywords: food balance, vitamins, iron, prevalence, student, stress 1. Introduction Food consumption is a complex act, which is the subject of studies in disciplines as diverse as epidemiology, economics, sociology, anthropology or psychology, as pointed out by Poulain [1] . In addition, Erlich [2] has been very interested in the relationship between the student and his socio-economic and demographic background. She showed how these students gradually gain independence from their family and friends and adopt a new way of life and a new relational network. In addition, much work has been done on the anxiety and depression that accompanies the transition to academic life [3] and stress management [4] . The caloric intake you need depends on your gender, your age and the activities you do during the day. You need about 50% of the energy in the form of carbohydrates, 35% in the form of lipids and 15% in the form of proteins. 60% of students judge their diet is balanced. Yet 24% admit to eating no fruit, 35% no vegetables and 14%, no fruit or vegetables every day. On the other hand, they are 95% to eat between meals. In addition, 44% of them skip breakfast, the meal supposed to be the most complete and energetic of the day. 60% of them say they are not hungry or have no time to take it. More worrying: 12% of them explain this removal of a meal by financial problems Finally, to preserve a good intellectual tone, a food rich in iron that allows the transport of oxygen to the brain (egg yolks, lentils, quinoa, mollusks,...), and phosphorus (fish) will benefit you. To this end, the research work we have carried out is part of the National Nutrition Program (PNNS) campaign, given the almost categorical lack of statistical data to guide and monitor the health policies adapted to students. 2. Materials and Methods Data collection was done using a completed questionnaire with students leaving university campuses. The questionnaire consists of 82 questions, some of which are multiple choice, others are "open" or "closed". These allow faster data processing. The questionnaire consists of three parts:  Information and personal elements of the student:  Student feeding:  Perception of food by the student: The purpose of the questions asked is to briefly assess the student's knowledge of food in general and its impact on health. Adding, the surveys were carried out among university students in the cities of Rabat, Marrakech, Tangier and Kenitra during the period from 28 February to 10 May 2013. The study concerns Moroccan university students aged 18-25 years. The sample consists of 55.13% female students and 44.87% male students. More than half, or 57.06%, are between the ages of 18 and 20 years. 3. Results and Discussion 3.1 Number of daily Meals according to the sex of students It is important that you make at least three meals a day. Even if you are stressed, it is important that you take the time to eat. Meals should be synonymous with relaxation. When you are in a period of revision or examination, your body needs energy and therefore you feed properly. You will not be able to concentrate well if you have nutritional deficiencies. These periods are therefore the wrong time to undertake a possible regime. Your body needs lipids, carbohydrates, protein, fiber, minerals
