Imagine not being able to eat anything with milk, eggs and peanuts.
That was the case for a local 11 year old boy.
But now he's been "cured" of his allergy to both milk and eggs...and is on the way to being cured of his peanut allergy.
And his experience could lead to treatments for millions of kids with similar reactions.
Just a few weeks ago a snack of French toast with a glass of milk would be off the table for Ryan Birchfield...along with a lot of other foods.
Ryan, "I was just waiting out till I could have like donuts and cake and cookie."
At less than a year old old his mom Colene discovered Ryan was allergic to milk, eggs and peanuts.
Colene Birchfield, Mom, "It was learning curve. Anytime we went to play group with kids or to school or to any function, a sporting event where they had these types of snacks and foods."
Here's what would happen to Ryan when he was exposed to eggs.
But not anymore.
Ryan's one of 55 kids who took part in a UNC Chapel Hill Study just released in the New England Journal of Medicine.
Colene, "The hope is that you can just gradually build your tolerance and desensitize those cells that are trying to fight infection to not to do that so that your body can accept it."
This video shows Ryan having a mild reaction during the study and giving himself relief with an Epi-Pen.
Ryan, "It can be anywhere from feeling nausceaus and throwing up to not being able to breath,"
Now Ryan has effectively been declared cured.
He can eat eggs.
A similar study led to the same results with milk and now he's trying for a peanut cure.
Colene, "It's just, it's kind of amazing. It feels good actually to not have to worry about all that."
Researchers expect treatments from the study could be available for everyone in a couple of years.
Ryan just started the peanut allergy study.
It's expected to take 4 to 5 years.Click here to learn more about the egg treatment research.
