It's not just pea allergies that are becoming more common. Experts also suggested that allergic reaction warning labels should be added to foods containing pine nuts, buckwheat and sheep and goat's milk.
Annabel, 20, has just completed a degree at the University of Cambridge. She's allergic to pine nuts and believes adding them to the list of allergens could potentially be "life saving" for her.
Like Charlotte, Annabel finds communicating her allergies to restaurant staff can be very hit or miss.
"I often feel like my allergy is not taken seriously," she says. "When I state an allergy to pine nuts, the vast majority of the time they reply 'peanuts?'"
She says staff often tells her there's no nuts in her food but thinks they just mean the nuts which are recognised as part of the 14 allergens.
She's had three anaphylactic reactions, including when she was informed by restaurants that her meal didn't contain pine nuts.
Annabel says adding it to the list would make her feel "so much more confident" when eating out.
"A lot of my family like to eat out quite a lot and I often don't want to go, or when I'm with my friends I'm always telling everyone around me 'this is where my EpiPens are, this is what to do if something happens', [so] to have that safety and to not worry would be such a big difference to me."
The Food Standards Agency said earlier it recognised there were a significant number of foods that could cause allergies or intolerances.
While Allergy UK said it was calling for full ingredient labelling on all food products while keeping an eye on worrying trends.
