Five‑Year Parasite Infection Confirmed Claire Foy says she likely contracted intestinal parasites while traveling in Morocco and lived with the infection for “at least five years” before it was diagnosed, a timeline reported by both outlets [1][2]. She experienced unexplained weight loss that matched NHS‑listed parasite symptoms, prompting medical testing that revealed the organisms travel in pairs [1][2]. The prolonged infection coincided with an underlying autoimmune condition that later guided her dietary choices [1][2].

Natural Remedies and Caffeine Cessation After diagnosis, Foy avoided strong antibiotics and turned to natural remedies to eradicate the parasites [1]. She also gave up caffeine, cutting out roughly 15 cups of tea daily, because she believed it aggravated her gut issues [1][2]. Both sources note the caffeine quit formed part of a broader effort to reduce gastrointestinal inflammation.

Gluten‑Free, Low‑Sugar Regimen for Autoimmune Health Foy disclosed that she now restricts gluten and sugar to manage her autoimmune condition, eating them only occasionally when dining out [1][2]. She describes the diet as “very strict,” though she admits to occasional lapses that do not trigger allergic reactions [1]. The dietary shift aims to lower systemic inflammation rather than address specific allergies.

Revelation Shared on Table Manners Podcast Foy detailed her health journey on the “Table Manners” podcast hosted by Jessie and Lennie Ware, an episode released on Wednesday, February 4, 2026 [1][2]. The interview also touched on her upcoming film projects, including “The Magic Faraway Tree” and “Savage House,” underscoring her continued career momentum [2].
