Human Health and Nutritional Sciences
Why Study Human Health and Nutritional Sciences at U of G?
"Let food be thy medicine, and let medicine be thy food.”
~ Hippocrates
Human Health and Nutritional Sciences explores the biological, physiological, and nutritional foundations of human health, with a particular emphasis on the importance of lifestyle choices and the potential for innovative products to prevent illness, boost performance and promote long-term well-being.
After building a foundation in the biological sciences in first year, you’ll investigate how foods, beverages, and nutritional supplements affect human health and wellbeing, from a molecular and cellular level to entire systems. In senior years, you will dive deeper, taking courses on the role of nutrients in maintaining health and preventing and treating disease, the connection between foods, nutritional supplements and pharmaceutical drugs, the impacts of exercise and lifestyle choices on health, and regulatory policies, among other courses.
Equipped with a strong understanding of the science behind health and well-being, you’ll graduate prepared to become a leader in the field of holistic health, supporting others in living longer, healthier lives.
Note: The Human Health and Nutritional Sciences major was previously known as Nutritional and Nutraceutical Sciences. The new name is effective for the incoming fall 2026 class.
Develop a Foundation in Human Health and Nutrition
Offered within the Department of Human Health Sciences, this major provides a broad grounding in the biology of nutrition, anatomy, physiology, and lifestyle medicine.
Help Solve Contemporary Nutrition Issues
Tackle pressing problems in the growing food, wellness and nutritional supplement industries through a deep understanding of how nutrients, phytochemicals, toxins and food processing affect the human body. With courses focused on functional food development and clinical trials for functional foods, you’ll have the tools to evaluate new products, address misinformation and innovate responsibly.
Gain Hands-on Research Experience
Complete a research course with a faculty member in a discipline related to nutrition, food, nutritional supplements, health and disease to further your skills and experience. Access cutting-edge research institutes working to further our understanding of nutrition and health, including the Human Nutraceutical Research Unit and the Guelph Family Health Study.

Hear From HHNS Students and Graduates

The Human Health and Nutritional Sciences program taught me how nutrients can help prevent and treat diseases and gave me the chance to explore how bioactives in food can be used to create innovative products. I really value the understanding I gained about the steps involved in bringing such products to market, as it's something I can now apply in my current role.

My advice to those even slightly considering applying to Human Health and Nutritional Sciences, would be to apply! There are so many different career paths afterwards and people are transitioning to a more holistic approach which is exactly what the program encompasses.

Enrolling in the HHNS program at U of G has been a uniquely transformative experience, shaping my personal and academic development. From the moment I joined, I knew there was no other program that so effectively explored the world of nutrition in relation to biological health. Many unique courses emphasize hands-on learning, allowing me to apply what I’ve learned to real-world challenges. The program also went beyond clinical nutrition and highlighted important aspects such as food policy and regulatory affairs.

I chose the University of Guelph’s HHNS program due to the unique academic training it provides, alongside practical experiential learning opportunities. This degree program allowed me to go beyond clinical nutrition and explore nutrition in relation to biochemistry, public health, food product development, regulatory affairs, and much more. With diverse departmental research and industry-related projects, I gained a rich set of analytical, research, and professional skills that propelled my professional and academic careers.

Being in the HHNS program allowed me to gain relevant hands-on experience through many unique group projects. This program covered various topics in human health and nutritional science and provided me with relevant knowledge to apply to various careers. Being in a smaller program also allowed me to get to know other students and form a sense of community. It also allowed me to form relationships with professors. These relationships turned into many opportunities, such as completing upper-year research projects and finding a professor to work with for my master's degree.

What sets the HHNS curriculum apart is the wide range of topics it covers, as students have the opportunity to explore topics of their interest in-depth through the support of a faculty with a broad range of expertise in the field. Additionally, the program provides a variety of other opportunities for students to take part in, including the Student Association and fourth-year independent projects, both of which I benefitted from.

What sets the HHNS program apart is its multifaceted approach that extends beyond its core focus on physiology and the intricate relationship between nutrition and the human body. We were equipped with a robust comprehension of important aspects such as food policy, intricacies of the food industry, and the skills to utilize existing research to formulate functional food products compliant with Canadian food regulations. The program also provided invaluable insights in the realm of nutrition research.
The program's expansive scope has uniquely positioned me for diverse roles within the nutrition landscape, spanning industries, governmental sectors, and academia, affirming its exceptional value in shaping a versatile and impactful career trajectory.
