Dr Blekkenhorst is a National Heart Foundation of Australia Post-Doctoral Research Fellow in the School of Medical and Health Sciences and holds an NHMRC Emerging Leadership Investigator Grant. Her research aims to better understand the vascular and metabolic health effects of specific vegetables and their bioactive constituents, as well as findings new and improved ways to encourage people to eat more vegetables every day to improve health outcomes.

Background

Dr Blekkenhorst was awarded her PhD from The University of Western Australia in July 2019. Her PhD research investigated the cardiovascular health benefits of specific vegetables and their constituents. In particular, dietary nitrate, found abundantly in vegetables, was a major research focus. Dr Blekkenhorst is a Registered Nutritionist with the Nutrition Society of Australia (NSA) and is currently the Secretary for the NSA Perth Regional Group. She has expertise in the design and conduct of randomised controlled trials and observational studies that focus on the vascular and metabolic health benefits of vegetables and their bioactive components. Her research has been published in leading nutrition journals, including the American Journal of Clinical Nutrition, Molecular Nutrition & Food Research, Clinical Nutrition, and the European Journal of Nutrition.
