This is what Meghan Markle will now have to give up when she travels

That’s one hefty royal rule book…

Meghan Markle has fitted seamlessly into the royal family from the moment she started dating Prince Harry, from bonding with the Queen’s corgis to getting an early invite to spend Christmas at Sandringham with the Windsors.

And now that the couple have tied the knot, Meghan is officially a royal, with the Queen giving Prince Harry and Meghan Markle the titles, Duke and Duchess of Sussex, as a wedding present.

Since becoming a royal, Meghan has made some noticeable changes, deleting her social media pages, wearing tights to public engagements, changing her handwriting and curtsying to both the Duchess of Cambridge and Queen Elizabeth on the regular.

With her first royal tour in sight, Meghan now has a list of royal travel rules to add to her Princess lessons - and surprisingly, it’s all about diet.

The royal family is said to be banned from eating shellfish while abroad - something that Meghan will now have to follow as she assumes her royal duties.

These dietary requirements have nothing to do with weight or appearance however, instead being imposed to ensure that the royal family stay healthy, avoiding the food poisoning risks that come along with it.

In fact, rare meats and tap water from foreign countries are also said to be on the no-go list for the same reason.

With their busy schedule, especially when on tour, food poisoning can cause huge disruptions so they are advised not to chance it.

While not a rule, the royal family is also said to moderate its intake of garlic and onion – for the simple reason that their job involves a lot of ‘meeting and greeting.’

While the Queen is said to stick to the guidelines, the younger generation of royals are said to have a more relaxed approach.

We get it – they may live in palaces but is never being able to eat Moules-frites again and limiting your garlic intake really worth it?
