Catherine follows a careful approach to her diet, especially in the days leading up to major events. Foods that could potentially cause food poisoning or digestive issues are meticulously evaluated and often avoided. The reasoning is straightforward—why risk health issues when so many responsibilities hinge on being well?
This isn’t about being overly restrictive or living under strict rules; it’s about preventing avoidable problems. Catherine’s role involves meeting people, speaking publicly, and extensive travel, making her health a critical aspect of her duties.
An insider noted that while most people can take a sick day when unwell, the situation is more complex for a senior Royal Family member. Security arrangements, diplomatic factors, media commitments, and the expectations of thousands make precautionary measures, even those related to food and drink, crucial behind the scenes.
Garlic and raw onions are reportedly avoided in Catherine’s diet during public engagements due to concerns over breath odors at meetings and official events.
Queen Camilla, 78, confirmed this practice during an appearance on MasterChef Australia, stating, “Garlic is a no-no…You always have to lay off the garlic.”
Catherine is also barred from consuming foie gras at royal residences due to a longstanding policy by King Charles, 77. This luxury dish, made from the liver of force-fed ducks or geese, was removed from royal menus over animal welfare concerns.
Spicy food presents a more nuanced challenge. Although heavily spiced meals are usually avoided on official tours to prevent digestive discomfort, Catherine has expressed a fondness for spicy foods when cooking at home.
In 2019, she shared, “It’s so hard cooking curry with the family… the children have a portion with no spice, (William’s) is medium. And I quite like it hot. Charlotte is pretty good with heat.”
