Clinical nutrition is a discipline that deals with the prevention, diagnosis and management of nutritional and metabolic problems related to acute and chronic disease and conditions caused by a lack or excess of energy and nutrients. The Clinical Nutrition Research Unit aims to tackle these issues through research into three key research axes:

The Clinical Axis

Comprehensive Assessments
To better understand the relationship between lifestyle factors and health outcomes, researchers need to conduct detailed health and nutritional assessments. The new site will be outfitted with sophisticated equipment that allow for comprehensive physiological measurements of body composition and provide continuous monitoring of blood glucose levels and blood pressure.
Assessment Area
A fully equipped assessment area allowing comprehensive physiological measurements of body composition and sampling of biospecimens.
听
Exercise Room
An on-site exercise room allowing researchers to evaluate the body's response to exercise challenges under different conditions, and is equipped to precisely measure metabolic parameters.
Food Pharmacy
This first in Canada food pharmacy will be a space to promote the consumption of therapeutic foods among patients who require dietary startegies to manage a chronic condition.
Meeting and Observation Rooms
For evaluating eating and self-management behaviours that will be combined with the data obtained from the physical assessments. Researchers will host focus group discussions and interviews to develop a self-management platform for diabetes.
The Behavioural Axis
Eating behaviour is an important determinant of health. Our food choices can be susceptible to multiple factors, both internal (e.g. hunger) and external (e.g. food advertisements).
Dietary patterns have changed in recent decades due to a greater availability of inexpensive foods and the widespread presence of food marketing.
Exposure to food marketing, such as commercials and social media content, has been related to increased consumption of calories, and therefore to increased risk of obesity.
Current Research
The CNRU can collect data outside of the lab using wearable pieces of equipment that can be used for conducting studies in a natural setting.
The CNRU is currently conducting a study in which we evaluate changes in appetite, neuroactivity, and visual attention during/after exposure to food commercials of highly-palatable foods,听 considering genetics and hunger state.
State-of-the-Art Equipment
Observing eating behaviours is an important part of helping people improve their nutritional habits.
Sensometric Lab
The sensometric lab aims to evaluate food-related sensation, perception and cognition in carefully controlled settings.
Dining Observation Area
Experimenters can observe participants' eating behaviours through a mirrored window overlooking a realistic living/dining room.
Modern Equipment
Computerized tasks, questionnaires, brain imaging devices, and biometric sensors such as eye trackers and heart rate monitors are used to study reactivity to food cues.
听
Equipment highlight:
Our portable functional near-infrared spectroscopy device collects brain activity measurements in a non-invasive and silent way while participants move freely.
The Precision Nutrition Axis
This branch of nutrition aims to design unique and dynamic nutrition strategies based on personal data, such as genetics. Other factors such as dietary patterns, health status, microbiome, and metabolism can also be considered.
Research themes
- Studying how genes and diet together are related to health outcomes
- Investigating the role of local food environments in the relationships between genes and health outcomes
Research on nutrition and genetics helps us understand
How a person responds to a diet based on unique aspects of their DNA
The biological mechanisms behind a person's metabolic response to food and nutrients
听
How does it work?
Chronic disease involves many genes (they are polygenic)
Genes are influenced by what we eat (dietary exposures)
We can study interactions between genes and diet to better prevent, manage, and treat chronic diseases
What will the science reveal?
Precision nutrition interventions that integrate genetic information and/or other personal data
Improved prevention and management of diet-related chronic diseases
Advance the science for developing dietary recommendations
听
听
Epidemiology Lab
The lab is equipped with high performance computers to help analyze "big data" from large cohort studies involving hundreds of thousands of participants.
We evaluate relationships between data on genetics, diet, eating behaviour, social factors, the retail food environment and markers of health.
