Areas of Research
Seek to understand the potential of nutrition to prevent and treat chronic disease.
Study the influence of diet on our microbiome and find dietary interventions that can improve gut microbiota composition and function in chronic disease.
The Reimer Research Group focuses on understanding the full potential of nutrition to prevent and treat chronic disease. Their research spans basic science to determine the mechanisms through which diet affects the progression and maintenance of obesity through to applied human clinical studies evaluating the effectiveness of novel dietary interventions.
A central focus of the Reimer group is to understand the influence of diet on our microbiome and how we can use dietary interventions to improve gut microbiota composition and function in chronic disease. The Reimer lab has pioneered research in the use of prebiotics to prevent and treat metabolic diseases such as obesity, fatty liver disease and diabetes. In rodents, the lab is examining the following:
- Influence of maternal diet during pregnancy and lactation on shaping the microbiota of mother and offspring and the resultant obesity risk of the offspring. Maternal factors currently under investigation include prenatal and early postnatal antibiotic exposure, maternal artificial sweetener consumption, maternal prebiotic fiber intake, and early postnatal milk oligosaccharide intake.
- Effect of dietary manipulation of the gut microbiota with prebiotics and probiotics (alone and combined) on metabolic health in obesity, fatty liver disease and type 2 diabetes.
- Examining the brain – gut microbiota axis in early postnatal life with implications for depression and anxiety.
- Influence of paternal (father’s) diet on offspring metabolism later in life.
- Identifying optimal dietary patterns (rich in a variety of dietary fibers) to promote gut microbiota health.
In human clinical studies, the group is currently focused on determining whether prebiotics can improve gut microbiota and disease management in children and young adults with newly diagnosed type 1 diabetes as well as examining whether prebiotics can reduce pain and improve physical function in adults with knee osteoarthritis and obesity.
The long-term goal of the work is to identify novel nutritional therapies to prevent and treat chronic disease.
