Casein

Casein intolerance involves the digestive system’s inability to properly process casein, resulting in discomfort and various symptoms. Unlike a casein allergy, which is an immune reaction to the casein protein, causing potential severe symptoms like hives, swelling, or anaphylaxis, casein intolerance is a non-immune response. It generally leads to milder, primarily digestive-focused symptoms and does not involve the immune system.

• Bloating and gas
• Abdominal pain
• Diarrhea
• Nausea
• Indigestion
• Headaches

If you regularly experience digestive discomfort such as bloating, abdominal pain, or diarrhea after consuming dairy products containing casein, it may be advisable to consider a test for casein intolerance. This is particularly important if these symptoms disrupt your daily activities or if the specific cause of your discomfort is unclear, as it could indicate other dietary sensitivities or health issues.

Managing casein intolerance involves avoiding or limiting dairy products that contain casein. This includes reading food labels carefully, as casein is present in many dairy products like cheese, milk, and yogurt. Seek alternative dairy-free options like almond, soy, or oat milk and dairy-free cheese. For nutrients typically found in dairy products, such as calcium and vitamins, include other sources in your diet. Consulting with a dietitian can provide guidance on maintaining a balanced diet while avoiding casein. Keeping a food diary can also be useful in identifying other potential food intolerances and in tracking dietary adjustments.
