Can a person be allergic to yellow cheese but not white cheese?

It's not common, but it's possible for a person to be allergic to yellow cheese but not white cheese. Here's why:

* Allergy to milk proteins: Many cheese allergies stem from allergies to proteins found in cow's milk, such as casein and whey. While these proteins are present in both yellow and white cheese, the concentration and processing methods can vary.

* Additives: Yellow cheese often contains added ingredients like annatto, which gives it its color. This dye can cause allergic reactions in some individuals, leading to a specific reaction to yellow cheese.

* Aged cheese: Yellow cheese is more likely to be aged, which can break down some proteins, potentially making them less allergenic. However, aged cheese can also contain more tyramine, a compound that can cause reactions in some people.

It's important to note:

* Cross-reactivity: A person allergic to one type of cheese may be allergic to other types as well.

* Diagnosis: It's crucial to consult with a doctor or allergist for proper diagnosis and guidance. They can perform allergy testing to determine the specific cause of the reaction.

In summary: While unusual, it's possible for someone to be allergic to yellow cheese due to specific additives, aging processes, or varying protein concentrations compared to white cheese. However, it's always best to seek professional advice to understand the root cause and receive the appropriate care.
