Tuna

Tuna intolerance involves the digestive system’s inability to properly process tuna, resulting in discomfort and various symptoms. This is a non-immune response, unlike a tuna allergy, which is an immune reaction to proteins in tuna, potentially causing severe symptoms like hives, swelling, or anaphylaxis. Tuna intolerance generally leads to milder, primarily digestive-focused symptoms and does not involve the immune system.

• Bloating and gas
• Stomach cramps or discomfort
• Diarrhea
• Nausea
• Indigestion
• Headaches

If you consistently experience digestive issues such as bloating, stomach cramps, or diarrhea after eating tuna, it may be wise to consider a test for tuna intolerance. This is particularly important if these symptoms frequently disrupt your daily life or if the specific cause of your discomfort is unclear, as it could be indicative of other dietary sensitivities or health concerns.

Managing tuna intolerance involves avoiding or limiting tuna in your diet. Since tuna is a common ingredient in salads, sandwiches, and sushi, it’s important to read food labels and menus carefully. Seek alternative protein sources like other fish varieties, poultry, or plant-based proteins that do not cause discomfort. Consulting a dietitian can be beneficial for ensuring a balanced diet while avoiding tuna. Additionally, keeping a food diary can help in identifying other potential food intolerances and in monitoring your dietary adjustments.
