King Charles 'Shrieked' When He Saw Saran Wrap for the First Time, Royal Book Claims

The King's habits surrounding food are reportedly evolving even up to the present day

King Charles "shrieked" when he found out about Saran Wrap for the first time, according to a royal book.

Tom Bower wrote in his 2018 book Rebel Prince that the King (who was Prince Charles at the time) "shrieked" and "trembled" the first time he interacted with cling film (better known as Saran Wrap in the U.S.) when it covered his dinner.

The Guardian reports that Queen Camilla had to calm down the King, 75, and explain what the perplexing plastic covering was.

"He walked into the dining room and shrieked," Bower wrote, via The Mirror. "Fearing the worst, Camilla dashed in after him. ‘What’s this?’ asked her husband, pointing at the food."

“It’s cling film, darling,” she replied, as per Bower's book, which claims that the monarch was disconnected from the ordinary world.

This revelation is making the rounds online again as new details about the King's diet have been made public.

The monarch, who typically would skip lunch according to his stepson Tom Parker Bowles' forthcoming cookbook Cooking and the Crown: Royal Recipes from Queen Victoria to King Charles III, is now embracing a midday meal.

The King “doesn't eat lunch at all," Parker Bowles, 49, writes, instead enjoying a "relaxed" afternoon tea at 5 p.m. of "macaroons, scones, wafers, biscuits, petit fours, ­pralines, Chelsea buns and shortbread, along with bridge rolls, crumpets, poached eggs on toast, potted shrimps and sandwiches” packed with “chicken, smoked salmon, ham and mustard.”

The King and Queen, 77, also prefer a “laid back” dinner “away from the official pomp and circumstance," as per Parker Bowles — aside from any official events and formal banquets, of course.

The monarch's lunch habits have since shifted, however. Amid his cancer treatment, the King has added a midday meal to his diet. A source told the Daily Mail that "With some reluctance, he now has something to eat at lunchtime — a snack, really."

"He now eats half an avocado to sustain him through the day. It's important, particularly if you have got an illness," the source continued.
