The main value of man is his health, which, unfortunately, in the population of our country is continuously deteriorating. It is noted the widespread increase of digestive diseases, cardiovascular, endocrine systems, the increase of cancer diseases (Volodin V.V, 2006). Of particular concern is the health of today’s youth. One of the key factors in the complex health promotion is good nutrition. A wide range of products with a lot of preserve agents and a long shelf life, fast-food, all sorts of nutritional supplements, the introduction of foods with genetically modified food-stuffs, advertising in the media of different diets help to reduce the food quality of modern man, and especially of young people.

The aim of our study was to assess dietary intake of 543 students (419 girls and 124 boys aged 16-22 years) of 1-4 courses of two universities in Samara. The results of investigations have shown that only 50% of girls and 60% of boys receive a three meals nutrition a day. About 5% of students eat only once. 56-59% of young people always have breakfast . For most students (67% of girls and 58,5% of boys) breakfast consists of a sandwich and a cup of tea or coffee. Porridge in the morning diet is for 14% of girls and 23% of boys. 6% of girls and 10% of boys like to eat for breakfast meat dishes. There are low levels of dietary carbohydrates with a share of digestible mono-and disaccharides accounted for more than 40% while the amount of amyloid compounds, such as bread, cereals are actually absent. Only half of girls and 68.5% of boys have in the daily diet bakery products, every fifth student consumes them at least three times a week. In the widely discussed scientific literature there are mechanisms of antitumor effect of starch, it is known its ability to alter the microbial composition of the colon, starch dextrines cause a reduction in cholesterol level and low density lipoprotein as well as and putrefactive metabolites in the intestine of humans. Low consumption of stuff-foods containing starch may adversely affect the human body. There are detections of low consumption by students of foods rich in fiber and pectin substances: fresh fruit and vegetables in the diet on a daily basis are only for every second girl and 40.3% of boys. Most students (62%) prefer salads with mayonnaise. Daily consumed ketchup is for 16% of young people and 9,3% female students. Young people consume fish infrequently: each second - at least once a week. The results of evaluation of nutrition quality have shown that the modern student does not get all the necessary macronutrients insufficiently. The consumption of protein quantity varies from 26 to 120 grams per day. In this case every fifth student uses the protein in an amount less than the protein minimum. .It was revealed that most young people seem to be consuming a sufficient amount of fats. However, the main source of fat is, unfortunately, mayonnaise and chocolate, the content of the diet of vegetable oil - a source of polyunsaturated fatty acids - is very low. Butter is consumed be only 31% of girls and 47% of boys. In addition, 7% of the students have shares of lipids in the diet less than 30.0 grams per day. Thus, we can say with certainty that the nutrition of today’s students is not well balanced. It is stated that there is frequent lack of breakfast and reduction of the number of meals per day, reduction of the total daily caloric intake, lack of protein, vegetable fats and carbohydrates (such as polysaccharides and dietary fibers and pectin substances). In this regard, it is important to perform the formation of the students responsible attitude towards health, education and promoting healthy lifestyles, including training hygienic principles of healthy nutrition.
