B. A New Solution For Food Allergies

Narrator: This is Science Today. People and dogs with food allergies may benefit from a naturally occurring protein called thioredoxin. A team of researchers from three University of California campuses, led by Bob Buchanan of UC Berkeley, found thioredoxin reduces the allergenicity of milk and wheat by essentially tricking the immune system.

Buchanan: Many of the food allergens, especially from plants, are proteins that contain sulfur to sulfur bonds. When thioredoxin interacts with these proteins with the sulfur to sulfur bonds that are food allergens, they change their shape and so the immune system can't recognize them as well.

Narrator: So far trials have only been used on dogs , but Buchanan says their allergies are quite similar to humans.

Buchanan: Unlike some studies, we're going to make the life better for the dogs, as well as for the people. We're doing work on behalf of each and probably the dogs will benefit before the people if it all works out.

Narrator: While researchers are now working to break down allergens in canine food, Buchanan says human trials will be the next step. For Science Today, I'm Larissa Branin.
