Meghan Markle will be adjusting to life as the Duchess of Sussex, which apparently comes with a LOT of rules - even controlling which foods she's allowed to eat.
New reports reveal that Markle, and in fact all members of the royal family, are forbidden to eat garlic during public events. UK newspaper the Sunday Express revealed that garlic is banned - especially when in Buckingham Palace.

- Why does Meghan Markle have to curtsy for Kate Middleton if they're both Duchesses?
"With many meetings between official visitors, it is thought to be advised against to prevent any awkward bad breath."
The rule doesn't seem likely to change any time soon, since Queen Elizabeth II notoriously hates garlic.
"We can never serve anything with garlic or too much onion," Darren McGrady, royal chef at Buckingham Palace, explained to Recipes Plus. "The Queen would never have garlic on the menu."
It means garlic will be off the menu when Prince Harry and Meghan make their way to Aotearoa later this year, visiting New Zealand along with Australia, Fiji and the Kingdom of Tonga.
Luckily Markle is still allowed to eat garlic in the privacy of her own home, which is lucky as one of her favourite dishes to cook contains a lot it.
She told the Today Show how she liked to cook "Filipino-style chicken adobo" on Sundays, which contains the ingredient.
She said: "It's so easy - combine garlic, soy, vinegar, maybe some lemon and let the chicken swim in that sauce until it falls off the bone in a Crock Pot."
It's not the only thing off the menu for the Duchess of Sussex. Members of the royal family are also reportedly not allowed to eat shellfish while traveling for royal visits, due to the high risk of food poisoning associated with the dish.
While the rule has been somewhat relaxed over the years, the Queen sticks to it - and it's best not to argue with your new grandma.
