About

The purpose of the study is to assess the effect of a dietary intervention that includes the consumption of a novel functional yogurt (enriched with probiotics and polyphenols) on the blood biomarkers of healthy participants.

Full description

After having been informed about the study and the potential risks, all participants giving written informed consent will undergo screening to determine eligibility for study entry (inclusion criteria). At baseline (t0), a fasting blood sample will be taken by venipuncture from the participants, and they will be randomly assigned in a double-blind manner (investigator and participant) to one of the intervention groups, i.e. meal including the consumption of the functional yogurt (yogurt enriched with probiotics and polyphenols) or consumption of yogurt enriched with probiotics or consumption of placebo yogurt. The participants have to finish their meals within 15 minutes (t1) and after the meal, blood sampling will be repeated for the times, t2 = 30 min, t3 = 90 min, t4 = 180min. After a washout period of 7 days, the participants will consume the functional yogurt, or the yogurt enriched with probiotics, or the placebo yogurt, in a cross-over design, and the blood sampling will be carried out as described above. Finally, after a washout period of 7 days, the participants will consume the functional yogurt, or the yogurt enriched with probiotics or the placebo yogurt in a cross-over design, and the blood sampling will be carried out as described above. Throughout the interventional period participants' dietary intake, anthropometrical data, medical history, and dietary habits will be monitored.
