The following link is a report covering studies from the US alone and I believe, after my experience, that many more people suffer with food allergies without their knowledge. http://www.foodallergy.org/files/FoodAllergyFactsandStatistics.pdf
Movies frequently depict a person suffering an Anaphylaxic episode with outward signs including exaggerated swelling on the face and neck. It is unrealistic as depicted in this photo of movie star and comedian Martin Short, in the movie “Pure Luck” with co-star Danny Glover.
Or Will Smith in the movie “Hitch” as shown here:
I’m not saying some people don’t experience this extreme swelling from eating foods they’re allergic to. In-fact, my tongue was swollen so often that I got braces to increase the space in my lower jaw to allow more room for it, I had a bee sting on my pinky-finger that proceeded to cause my entire arm and neck to swell. What I’m saying is that it doesn’t always happen, sometimes you simply have what appears to be an asthma attack and you can show no outward signs of Anaphylaxis but in-fact be experiencing it and putting your life at risk.
I hope this helps you see why I went most of my life suffering food allergies without knowing and save you from thinking that you or someone you love simply has Asthma.
