Abstract: In this article, the importance of the energy caloric content in food products and the
requirements for the preparation of dietary regimes related to the health status, gender, and
physical activity of the individual have been discussed. Body mass index and the amount of fat
tissue in students aged 20-21 years have been evaluated. The microbiological safety of food is
also of great importance for health, as it could be e reason for food poisoning. The purpose of
the present study is to estimate the normal body mass, the amount of adipose tissue in students
and to analyzed the energy value of Bulgarian food products, which is a basic factor when
preparing a nutritional regime. The analysis for presence or absence of bacteria in food is also
determining for the individual’s health status. Contamination of food with bacteria can lead to
various toxic infections, food poisoning and infections. During the test, it has been found that
85% of the patients are with normal ITM and amount of adipose tissue. 10% are overweighted
and 5% have obesity II degree. Obesity II degree has very high health risk, accompanied by
concomitant diseases such as diabetes type 2, hypertension, cardiovascular diseases.
