Actress Claire Foy battled a five-year parasitic infection, likely from Morocco, managing symptoms with dietary changes.

Actress Claire Foy revealed on the podcast Table Manners that she had a parasitic infection for about five years, likely contracted in Morocco, causing unexplained weight loss and digestive issues. She avoided strong antibiotics, instead adopting a strict regimen that included eliminating caffeine, gluten, and sugar to manage both the infection and an autoimmune condition, aiming to reduce inflammation. She occasionally consumes these foods when dining out. Parasitic infections, treatable with medication, can result from contaminated food, water, or undercooked meat and are preventable through hygiene, safe food handling, and proper pet care.
