Claire Foy, the acclaimed actress known for her role as Queen Elizabeth II in 'The Crown', has opened up about her health struggles. In a recent podcast interview, Foy revealed that she suffered from internal parasites for a significant period, affecting her well-being and requiring dietary adjustments. She shared her experience of unexplained weight loss, which led to the discovery of the parasites, which she believes she contracted during her time in Morocco. Foy's revelation is particularly intriguing given her role as the monarch in a series that often involves historical accuracy and attention to detail. The actress humorously described the parasites as 'gross' and 'rank', emphasizing the discomfort and inconvenience they caused. To address the issue, Foy opted for a natural approach, avoiding harsh antibiotics and instead modifying her diet. This decision led her to give up caffeine, a challenging adjustment for someone who previously consumed a substantial amount of tea daily. Additionally, Foy disclosed her strict dietary restrictions due to an autoimmune condition, which she manages with a gluten-free and sugar-free diet, allowing for occasional indulgences when dining out.
