Gut Microbiome

YourGutBrain – Dairy for your gut and brain

The purpose of the YourGutBrain project is to investigate whether intake of fermented dairy and non-fermented dairy, respectively, affect weekly bowel movements and cognitive performance. This will be investigated through a dietary intervention study including healthy women with few bowel movements per week.

A wide range of measures related to the gut and the brain will be assessed upon consumption of fermented dairy and non-fermented dairy, respectively. Together, this will provide insights into whether dairy can affect bowel habits and cognition, as well as potential underlying mechanisms linking the gut and the brain.

Diet-derived microbial metabolites to modulate gut motility in infants

The Sapere Aude project will generate new knowledge about how gut microbes via production of small molecules can impact gut motility in infants.

Infantile colic, functional constipation and diarrhoea are stressful conditions in early life associated with transient dysregulation of intestinal motility, which may depend on the interplay between nutrition and the gut microbiota.

Infantile colic, functional constipation and diarrhoea are stressful conditions in early life associated with transient dysregulation of intestinal motility, which may depend on the interplay between nutrition and the gut microbiota.

The purpose of the project is to conduct an infant cohort study following infants’ progression from milk to solid foods, concurrent with their progression in gut microbiota diversity, with the aim of identifying diet-dependent gut microbial metabolites, which affect intestinal motility. If successful, this knowledge may lay the foundation for innovative strategies to prevent and alleviate stomach ache in infants.

Towards Personalized dietary Recommendations based on the Interaction between diet, Microbiome and Abiotic conditions in the gut

The project will generate more knowledge of the role the gut microbiota plays when people react differently to the same diet.

Focus areas

To investigate how the gut microbiota and environmental (abiotic) factors in the gut shape personal responses to food.

To investigate how and why digestion of food by the gut microbiota into small molecules (metabolites) varies from individual to individual.

About the project

You are what you eat, but why don’t we all react to foods in the same way?

Our guts contain a large community of microbes, and when we eat something and our microbes digest the food, they create products called microbial metabolites. These metabolites affect our immune system, our hormone balance, our health and possibly even our mood. When looking at dietary advice, there is no good ‘one-size fits-all’ solution.

In PRIMA, we want to explore the effect of diet from a different perspective, namely from your gut. We believe we can predict an individual’s response to a given diet based on fundamental factors such as pH and transit time in the gut, which govern the microbial responses. This way, we will develop better dietary advice tailored to a given person.

The project will investigate bifidobacteria's ability to fortify the gut barrier function via production of small molecules in early life

The purpose of the project is to investigate whether and how bifidobacteria produce a specific group of molecules in the infant gut and the molecules' potential to affect gut barrier function in early life. This knowledge may pave the way for novel strategies to strengthen gut function in early life.

The project will investigate gut microbial production, host-microbial metabolism, and function of aromatic lactic acids during infancy. 

We have previously shown that breastmilk-promoted Bifidobacterium species produce aromatic lactic acids in the infant gut, which may affect immune function (Laursen et al. 2021; Nature Microbiology). This project builds on these results and seeks to further decipher the absorption, metabolism, excretion and immune function of these molecules in infants.

NUTRIOME is a Marie Skłodowska-Curie actions (MSCA) Doctoral Network of the Horizon Europe. The focus of NUTRIOME is to train 10 PhD students in data-driven precision nutrition. 

We will seek to understand personal responses to meals by integrating microbiome and metabolomics data with emphasis on gut microbial metabolites as predictors of metabolic responses to meals.
