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.

Design and subjects: 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).

Setting: 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.

Conclusion: Regular intake of specially fortified food influences parameters, especially lipids and lipoproteins.
