It's very likely it was due to the incidence of beef and corn in the diets. Usually these allergies develop over time to proteins they have been exposed to. So, beef used to be one of the only proteins used, so of course, it's what we saw the majority of allergies to. Also taking into account that beef and corn were usually in the same foods, making it harder to know exactly what part was the actual problem.

Whether or not beef is still number one, I don't know. Many of the basic diets now have been chicken based for years. I'm sure that chicken allergies are probably on the rise, too!
