title: Effect of daily intake of yoghurt and bread enriched with biologically active substances on blood lipids and vitamin A in adolescents and young adults.
abstract: OBJECTIVE
  The aim was to investigate whether the daily intake of special nutrients, enriched with supplements from natural origins, has any effect on blood parameters.
  
  
  METHODS
  In this double-blind placebo-controlled clinical trial, 80 healthy subjects (mean age 26.3 years) were statistically assigned to two groups. Group I had to eat two special yoghurt and bread products a day. The other probands represented the control group (II).
  
  
  METHODS
  Plasma concentrations of blood parameters were measured at the beginning and at the end of the study, and dietary intake was calculated.
  
  
  RESULTS
  In group I, total cholesterol decreased. This was due to a significant drop of low-density lipoprotein-cholesterol from 106.0 to 99.0 mg/dl. A significant reduction of the apolipoprotein B and an increase of vitamin A in group I were also observed.
  
  
  CONCLUSIONS
  Regular intake of specially fortified food influences parameters, especially lipids and lipoproteins.
