Straight From The Expert: What is OAS?
With spring blooming and the arrival of pollen season, it's perfect timing to learn more about Oral Allergy Syndrome (OAS).
Food Allergy Canada hosted a not-to-miss webinar** with immunologist, Dr. Anne K. Ellis, Professor and Chair of the Division of Allergy & Immunology in the Department of Medicine at Queen's University in Ontario, on OAS.
Dr. Ellis demystifies OAS, aka Pollen Food Syndrome (PFS) — what it is, how it presents, and what you can do about this type of food allergy.
