Nutritional metabolomics

Kati Hanhineva

Research at the group pertains to the molecular level understanding of the role of nutrition in the prevention of chronic diseases. The research projects extend from the assessment of chemical composition of food all the way to the in vitro examination of biochemical effect of individual food-derived compounds. The key analytical technology at the different stages of research is the mass-spectrometry based metabolomics approach that enables novel metabolic discoveries as well as detailed molecular level examination of cellular metabolic processes.

Phytochemical composition of plant-based food and impact of industrial processing. One of the key features in edible plants is that they have very rich content of plant-made bioactive chemicals i.e. phytochemicals, and these components are most likely contributing to the beneficial health effects associated with plant-food rich diets. Many of our research projects focus on characterizing the phytochemical composition of Nordic foods such as whole grains and berries, and the differences between plant varieties. Additional topic of interest is how the industrial processes involved in the food making affect the composition of phytochemicals in the ready edible product. Special emphasis here is on processes involving microbial fermentation, such as sour-dough based bread baking.

Role of gut microbiota in the metabolism of diet-derived compounds. The colonic microbiota has a critical role in determining what kind of chemical array will enter our circulation from the ingested food. The relationship with gut microbiota is multifaceted, as also the diet affects the composition of microbes inhabiting the colon. Our aim is to understand what kind of chemical conversions the gut microbes can perform on diet-derived compounds, especially the phytochemicals, and what are the bacteria most associated and enhanced with healthy food, especially the Nordic diet.

Impact of diet in endogenous metabolism and role in disease prevention. The population-based evidence on healthy food is accumulating with increasing speed, and simultaneously, with the novel technologies we can have wider window to the metabolism in general as well as individual metabolic events related to certain diets and dietary compounds. Our aim is to better understand the metabolic impact of healthy diets underlying the beneficial health effects related to them. Particular focus here is within the gut microbiota derived metabolites and their relationship with cellular metabolic events.  We focus on both epidemiological collections as well as dietary intervention studies with the aim to locate novel candidate metabolites connected with beneficial health outcomes. In addition, we utilize also animal trials to be able to address the metabolism of individual organs. 

Molecular effect of diet-derived compounds in cellular processes. Although the metabolic impact of diet to our metabolism is a combination of thousands of chemical players acting in synergistic or even antagonistic effect, the examination of individual compounds can give us detailed information on certain cellular processes. Our aim is to take interesting, potentially bioactive candidate compounds into further examination on cellular level, and analyze their impact with various targeted as well as profiling techniques.
