Clinical Trial Summary

FLORA is a longitudinal intervention study with a randomized, parallel group design. Primary objective is to improve metabolic health through gut microbiota modulation by means of a retailer-driven personalized dietary intervention in a real-life setting. Four hundred Flemish pre-metabolic adults will be randomly divided into a control and treatment arm, each comprising 200 participants. The study period is divided into three phases: a four weeks characterization, a twelve weeks intervention, and a four weeks post-intervention phase. During the intervention phase, control participants' online Collect&Go shopping carts are adjusted in accordance with Flemish food-based dietary guidelines. Based on the same guidelines, participants are provided with personalized dietary advice considering their usual dietary pattern and level of food literacy. In the treatment arm, a similar intervention will be applied using guidelines based on a microbiota modulation diet (MMD). During intervention, all participants can contact a dietician helpline for additional advice on study-related dietary issues. Over the five months, saliva and fecal samples will be collected on a regular basis, with an intensive sampling period of seven consecutive days at the end of each study phase. A GP consult consisting of a short medical exam, blood withdrawal and medical questionnaire takes place each month. Further, online questionnaires on lifestyle, health and well-being will be sent by e-mail and each five days, participants complete a food diary through their smartphone. Fecal, saliva, blood samples and meta-data will be analysed to detect changes in metabolic health.
