I first figured out I had food allergies when I was 5. We were at a normal family dinner and we had beans. I had never reacted to them before but on that occasion I had a rash all over my skin, I had trouble breathing and I vomited all over the place. I was diagnosed with allergies and for the next day 3 years I kept developing/discovering new allergies (including dust mites, which I overcame after getting vaccinated for 4 years).
Nowadays I still have the same Food allergies: dry nuts, pepper, cheese, soy and beans (of any kind). Fun fact they are all deadly for me. At the beginning I only had slight reactions, but now I have to be extremely careful because any of them can cause me an anaphylactic shock.

And also I did research on my own for a project at school to explain what allergies are, and I grew fond of FARE’s website, highly recommend it ^^
