Why are people allergic to cheese?

People can be allergic to cheese, but it's not as common as allergies to other foods like peanuts or shellfish. Here's a breakdown of the reasons why someone might have a cheese allergy:

1. Milk Protein Allergy:

* The Most Common Reason: The primary reason for cheese allergies is an allergy to milk protein, specifically casein.

* Symptoms: Symptoms can range from mild (hives, itching) to severe (anaphylaxis).

* Cheese Types: Most cheeses contain casein, making them off-limits for people with milk protein allergy.

2. Lactose Intolerance:

* Not an Allergy: Lactose intolerance is not an allergy, but a digestive issue where the body lacks the enzyme lactase to break down lactose (milk sugar).

* Symptoms: It causes gas, bloating, and diarrhea after consuming lactose.

* Cheese Types: Some cheeses have lower lactose levels, making them more tolerable for people with lactose intolerance (e.g., cheddar, parmesan, Swiss).

3. Other Allergens:

* Mold: Certain cheeses, especially aged varieties, can contain mold, which some people are allergic to.

* Additives: Some cheeses have additives like dyes or flavorings that could trigger an allergy.

Important Note:

* Always Consult a Doctor: If you suspect a cheese allergy, it's crucial to consult a doctor or allergist for proper diagnosis and management.

* Read Labels Carefully: Even if you are lactose intolerant, check labels for "lactose-free" options.

* Cross-Contamination: Be cautious about potential cross-contamination if you are allergic to cheese.

In Conclusion:

While uncommon, cheese allergies can be a real concern. The most frequent cause is a milk protein allergy, but other allergens can also play a role. For proper diagnosis and management, always seek guidance from a healthcare professional.
