ABSTRACT
In the article there are presented results of a study of the balance of food consumption by the population of the Voronezh region, the assessment of the level of contamination of food products and both carcinogenic and non-carcinogenic and public health risk caused by this contamination. There was evaluated the level of nutrition-dependent diseases. A special feature of this study is a comparative analysis of data obtained during the two five-year periods of 1995-1999 and 2010-2014, that permitted to reveal changes in food consumption, the dynamics of morbidity rate associated with the nutritional factor.

Results of numerous researches have revealed that most sensitive to electromagnetic radiations are the nervous, endocrine and cardiovascular systems of an organism, however, the analysis of literary data confirms also the direct involvement of organs of the intestinal system in physiological, and not seldom, and the pathological program of the response of an organism to the action of extreme factors. In the experiment executed on white laboratory male rats by ourselves there was studied the grade of the radiosensitivity of morphoenzymological structural elements of jejunum mucous membrane after 5, 7 and 10 months of chronic influence of electromagnetic fields impulses with a density of induced currents 0.37; 0.7; 0.8; 2.7 kA/m and frequency of impulses 50, 100 and 500 in a week irrespective of their divisibility of ultrashort duration of 15 a 40 ns. Scientific value and novelty of results is concluded in revealed multiple linear relationships between indices of electromagneticfields (duration of the impact, density of induced currents, periodicity of impulses and the dynamics of the studied indices of a morphofunctional condition of a jejunum mucous membrane). Besides that, there was found the critical population to indices of electromagneticfields impulses parameters - the jejunum mast cells differing in hypersensitivity and dependence on duration of influence and density of induced currents revealed, at that their bioeffects were unidirectional.

There were obtained data which confirm the increase of efficiency of gas exchange processes in students and teachers of the engineering high school in the daily use of at least 3.5 g of wheat germ oil and 50 g of wheat germ cake flour without the correction of the basic ration. The study of the exhaled gas-air mixture showed in all age groups the gain in the concentration of carbon dioxide and the decline of concentration of oxygen by the 0.20-0.30%. There was established the increase of blood oxygenation level in all subjects. There was demonstrated the relationship between the depth of the alteration of these parameters with age, and regular physical activity in studied cases.
