Dr. Taylor investigates the effects of various dietary components on obesity, insulin resistance and vascular health using animal models and human studies. Specific dietary components she is researching include omega-3 fatty acids, conjugated linoleic acid, and plant-based bioactives in crops such as buckwheat and pulses. She is also researching the effects of zinc on antioxidant and immune defense.


Ph.D. (Department of Nutritional Sciences, University of Guelph), 1990
B.H. Ecol. (Department of Foods and Nutrition, University of Manitoba), 1984

Research Interests:

Dietary modulation of insulin resistance and obesity:  
Effects of dietary fatty acids [omega-3 fatty acids, conjugated linoleic acid (CLA)] and bioactive compounds found in plants/agricultural crops (e.g. buckwheat, pulses) on glycemic control, insulin resistance, adipokines and adipose function.

Nutrition, antioxidant and immune defense:  
Effects of dietary zinc on T-lymphocyte development and zinc-finger proteins involved in cell signaling. 
Protective effects of zinc supplementation during inflammation and heavy metal toxicity.
