[Effectiveness of the use of iodized milk protein to improve girls' sufficiency with iodine].

The work presents the results of the research capabilities of the use of iodized milk protein as a component of food supplement and enriched food product for the correction of iodine sufficiency in girls. Milk iodinated protein was produced by the enzyme-effective iodization of amino acid residues of cow's milk whey proteins. The study involved 30 girls, whose average age was 19.

[Energy requirements of miners engaged in open-pit coal mining].

It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of the working shift. The method of strict evaluation of the calorific value of the food taken and the control of body mass is acceptable for the assessment of daily energy consumption.

[Energy requirement of miners working in modern, highly mechanized coal mines].

It was established that under the conditions of modern highly mechanized coal mines, the miners' work refers mainly to the category of hard and particularly hard physical work. The data of energy losses obtained by indirect calorimetry and accurate calculation of the caloric value of the food taken and control of the body weight were found to be similar.
