"I remember looking at my grandmother and she was looking down at me and her face registered horror because my face had blown up - I was allergic," said Miller.
Sloane has had food allergies all her life, and though eating carries risks, she has embraced her condition, becoming a social worker and writing a book to help others who struggle with similar issues.
"Just because you have a restricted diet, does not mean you have to have a restricted life," said Miller.
Instead she's become a food sleuth she scrutinizes food labels at the grocery store.
"I read the labels every single time, because ingredients change," said Miller.
And when dining out she always tells the staff about her food allergies, and asks the wait staff to alert the chef.
Sloane finds more restaurants are catering to the needs of people with food allergies. But it's still important to ask questions, lots of questions.
And always carry medications in case of an emergency. Sloane knows that living with food allergies means managing risk, not eliminating it.
