Determination of vitamin D, iron and n-3 fatty acids in adolescents with different eating habits.

Objectives: Proper eating habits ensure human health, so it is important to eat a balanced diet and learn the basics of proper eating from an early age. Adolescence is considered very important period for maintaining good health in terms of nutrition.

Methods: In the study, we monitored the eating habits of 182 adolescents aged 14-19 years with different eating habits (73 vegetarians and 109 nonvegetarians) using a questionnaire on nutrition and determination of selected blood parameters - vitamin D, iron and n-3fatty acids.

Results: Insufficient levels of vitamin D were determined in the whole group of adolescents, regardless of eating habits. Low iron concentrations negatively affect the biosynthesis of long-chain n-3 fatty acids, which was also reflected in our adolescents with alternative diets.

Conclusions: Based on the obtained results, it is necessary to place emphasis on the composition of the diet in adolescent age.
