What this trial is about
The purpose of this study is to assess the effects of polyphenols from natural aronia juice on the immune system. Therefore, the study aims to distinguish the effects of natural juices that are rich in phytonutrients such as polyphenols and carotenoids in healthy and depressive subjects in order to use the known positive effects of these food sources in the therapeutic setting. The consumption of natural fruit juices that are rich in polyphenols and carotenoids mirror a model of vegetarian diet due to the increased micronutrient density derived from plant food. Results obtained here can be seen as preliminary explanation models for the beneficial effects of vegetarian diet. It is hypothesized, that the consumption of naturally polyphenol rich aronia juice changes the expression of regulatory T cells, specific cells of the immune system that contribute to immunomodulation. Furthermore, beneficial changes in the gut microbiome, the metabolome and the nutritional status are expected in the studied groups. The study was registered retrospectively (after start of recruitment) on Clinicaltrials.gov.
