There are many benefits to a well-balanced gut microbiome. There is less risk of diseases and it results in better overall health. It is known that aspects of our modern lifestyle, such as a one-dimensional diet with a lot of processed food, and the use of antibiotics, can lead to a less diverse composition of gut bacteria. The researchers are now going to study how a balanced gut microbiome can be achieved through diet.
VU Amsterdam microbiologist Kort: ‘The aim of this citizen science research is to make the participants in the study aware of the effects of the dietary pattern on the gut microbiome and on health, by asking them to put our dietary advice into practice in their own kitchen and to discuss the results of the study among themselves.’
Research structure
The study is a randomised controlled trial in which 150 healthy adults will take part. The researchers compare two different dietary interventions. Additionally, in the course of the study the participants learn more about the factors that affect the gut microbiota. The participants also get an insight into the effect of their dietary changes, through direct feedback of their own gut microbiota results. As well as the effects on the gut microbiota, the effects of these interventions on 92 inflammatory markers, gastrointestinal conditions, well-being and sleep will also be determined.
The research is being funded by MLDS, Cidrani, WholeFiber, Stichting Warm Nest and Keep Food Simple. Cooperation partners are MyMicroZoo, HORAIZON and UMC Utrecht. GEEF stands for Gut health Enhancement by Eating Favourable foods. Diet plays an important part in determining the diversity and composition of the gut microbiota.
Stimulating healthy eating habits with ‘GEEF om je buik’ study
26 April 2023
Researchers at VU Amsterdam and Wageningen University & Research (WUR), in collaboration with the Digestive Diseases Foundation (MLDS), are launching the study ‘GEEF om je buik’ [literally, care for your stomach]. Led by Professor of Microbiology Remco Kort and Food Health & Consumer researcher Nicole de Wit (WUR) they are investigating which dietary recommendations promote the diversity of gut microbiota, also known as gut flora. With this citizen science research – meaning citizens are actively involved – the researchers and MLDS aim to encourage a lasting lifestyle change.
