Like the rest of the royal family, Markle is now expected to follow a few notoriously strict diet restrictions—for good reason.

As newlywed Meghan Markle transitions into her royal duties, the former foodie and world-class traveler is facing a new set of diet rules that include a blanket ban on one of her all-time favorite foods.

Among many other restrictions, members of the royal cohort are banned from eating garlic or dishes that contain the heart-healthy staple known for it's rather pungent aroma. According to Britain's Daily Express, the flavorful addition is banned from meals for any royalty  traveling abroad or during official business occasions. The reason? Bad breath.

Plus, it doesn't help that Queen Elizabeth reportedly detests garlic.

Our friends at Food & Wine have previously reported on the Queen's distaste for garlic, which apparently has been banned at Buckingham Palace.

But if the royals are worried about how food is making them smell, there are ways to get proactive: Research suggests that a plant-based diet full of fruits and vegetables is linked to the least offensive body odor, leading us to believe that you are what you eat after all.

A higher intake of veggies leads to increased carotenoids (the pigments found in plants responsible for their vibrant colors) within the skin, which then influence the quality of the scent you put off after a meal.

Another major dietary restriction that the royals face while abroad on business is a blanket ban on shellfish. Why would delicious staples like lobster, crabs, clams, and shrimp be off the menu for a family that enjoys many worldly things? This is more related to health than to etiquette.

Hepatitis A is a serious threat to shellfish eaters in nations where water conditions could lead to contamination and a bout of possibly life-threatening food poisoning. Rather than risk it—or risk offending certain countries—it simply remains off the menu.

Markle will have to get used to all the ins and outs of dining before departing on her first official trip abroad to Dublin later this year. According to the Daily Express, the Duke and Duchess of Sussex's first tour will branch out to Australia before visits to Fiji, the Kingdom of Tonga, and New Zealand.

Their tour will kick off during the Invictus Games, which heads to Sydney in late October.
