Hair Trace Elements, Hematological and Psychological Parameters of Students with Different Diets

摘要

The effects of fast food, instant food and semi-finished products on trace element status, hematological and psychological parameters of students were studied. Students who consumed fast food, instant and convenience foods (the 1st group), as well as students who consumed nutrient-enriched health food (the 2nd group) took part in research (30 participants). Significant decrease in Co, Zn and K content by 1.5, 1.4 and 2.8 times respectively was found in the 1st group. Also in the 1st group significant increase in Cu and Na content was determined. Se content in the hair of all participants was lower than normal. The content of toxic elements in all respondents was in the normal range. Lower hemoglobin values were found in students with unbalanced nutrition, but these values did not indicate anemia. For psychological test questionnaire "Well-being, activity, mood" was used. For 27% students with unbalanced diet current psychological state was determined as unfavorable and only for 33% - as favorable. At the same time, the integral indicator of questionnaire "Well-being, activity, mood" positively correlated (r = 0.807, p <0.05) with the hair Zn level.
