For the past 20 years she has taught continuing medical education courses for doctors and other health care practitioners on the evidence-based use of diet and nutritional supplements in clinical practice. She is the author of two best-selling books on nutrition and health – The Healthy Brain (HarperCollins Canada, 2017), and Eat Well Age Better (Dundurn Press, 2012).  Her new book The War on Viruses will be published in April 2021 by HarperCollins Canada.

Presentation Abstract

Candida, Diet and Health: A New Twist on an Old Controversy

Conventional medicine considers Candida species to be harmless commensal organisms present in the normal gastrointestinal tract that can occasionally overgrow and cause invasive disease, mainly in immunocompromised individuals. In the 1970s the concept that colonization of the gut with Candida could cause an array of physical and neurological symptoms in non-immunocompromised patients, known as the yeast syndrome, gained popularity with integrative physicians but was dismissed as pseudoscientific and unproven by mainstream medicine.

Today, gut colonization with Candida is receiving renewed attention as a cause of Auto-brewery syndrome (ABS) or gut fermentation syndrome, in which the ingestion of carbohydrates results in endogenous alcohol production. The overproduction of endogenous alcohol in colonized individuals may explain many of the physical and neurological symptoms previously attributed to Candida, but generally dismissed. This talk will discuss diet and the use of selected natural health products to control the gut fermentation syndrome.

Born Aileen Philomena Reilly in Birmingham England, Aileen returned with her parents to their native Ireland when she was three years old. Her earliest education was at the Dominican Convent, Santa Sabina, Dublin, where her favourite activities were writing, drawing and performing in school productions. From there she went to boarding school at Loreto Convent, County Meath, where she learned little science but developed a lasting love of music.

Aileen’s scientific education began in earnest at University College Dublin where she obtained her Bachelor of Science degree. After graduation she moved to England to pursue a research career as a forensic biochemist in the horse-racing town of Newmarket, Suffolk. Her most enduring memory of that time was her futile attempts to appear calm and unruffled when collecting blood and urine samples from horses. (The horses were not fooled and to this day she is afraid of horses.)

While living in Newmarket Aileen met and married the love of her life, Roger Burford-Mason (d. 1998). They moved to Hitchin, Hertfordshire, where their son Oliver was born. After some years in teaching, she returned to research, this time in immunology. In 1983 she completed her PhD in immunology and continued research in that field until 1988 when she emigrated with her family from the UK to Canada.

Once in Toronto she moved into cancer research, holding positions as Research Associate and later Assistant Professor in the University of Toronto’s Department of Pathology. However, a nutritional thread had run through her research career, and she gradually became convinced that most disease had a major nutritional component that was being ignored. So in 1996 she made the transition from conventional research to orthomolecular medicine.

Today Aileen divides her time between her private practice, writing, and lecturing to medical and allied health professionals on the evidence based use of diet and supplements in health maintenance and disease prevention. Eat Well, Age Better, her best-selling book, has been enthusiastically received by doctors and the public. The Healthy Brain, published by HarperCollins Canada in 2017 made the Globe and Mail’s top 10 non-fiction best seller list.
