Why Seafood Can Cause Allergies

Seafood is packed with nutritious proteins, but it also contains some “foreign” proteins. These can act as real antigens in the body, triggering an immune response and causing allergies. Additionally, consuming seafood with high levels of histamine can lead to allergic reactions for anyone.

Allergic reactions can manifest in various ways, including external symptoms such as itching, redness, swollen blood vessels, itching, and bloodshot eyes. Internal symptoms can include swollen lips, mouth, and throat, vomiting, abdominal bloating, flatulence, abdominal pain, and diarrhea. If anaphylaxis occurs, along with cardiovascular collapse, hypotension, or laryngeal spasm, immediate medical attention is crucial as it can be life-threatening.

Natural Home Remedies to Treat Seafood Allergies

In addition to medication, mild allergies can be managed at home with easily accessible natural ingredients. Here are some effective remedies:

Pure Honey

Honey is a natural antibacterial and anti-inflammatory agent. Drinking a glass of warm water mixed with pure honey can help fight harmful bacteria and soothe the body, reducing allergic symptoms like itching.

Lemon Water

The natural ascorbic acid in lemons promotes the healing of internal damage. Additionally, the vitamin C in lemons boosts immunity, fights bacteria, and prevents allergies.

Drinking a glass of warm water mixed with fresh lemon juice is an effective way to treat allergic reactions like hives and itching.

Ginger

As you may know, ginger has a warming effect and possesses antibacterial, detoxifying, and antioxidant properties. It is a popular natural remedy for seafood allergies.

You can cook ginger into a tea or try this folk remedy: Take 10g of raw ginger, 15g of perilla leaves, and 15g of cattail roots, clean and grind them, then squeeze out the juice. Clean 100g of mung beans, put them in a pot, add water, and pour in the juice. Simmer until the beans are soft and enjoy it warm.

Drink Vegetable and Fruit Juices

Juices from vegetables and fruits are rich in vitamins and minerals, offering numerous health benefits. They help detoxify the body, boost immunity, and reduce allergic reactions. When dealing with a seafood allergy, try drinking a glass of carrot, beet, cucumber, watercress, celery, orange, lemon, or pineapple juice to alleviate symptoms like hives.

Precautions to Avoid Seafood Allergies

To minimize the risk of seafood allergies, avoid consuming seafood that is dead or improperly prepared, as it may contain high levels of histamine due to bacterial contamination. Opt for well-cooked seafood instead of raw to reduce the chances of an allergic reaction.

Refrain from eating fruits immediately after consuming seafood. The compounds in fruits can interfere with the absorption of proteins and calcium from seafood. Moreover, the tannin in fruits combines with proteins and calcium to form insoluble precipitates that irritate the digestive tract, causing stomach pain and nausea.

Frequently asked questions

A seafood allergy is an adverse immune response to proteins found in certain seafood items such as fish, shellfish, and crustaceans. It is one of the most common food allergies, affecting approximately 2-3% of the adult population and up to 4% of children.

Symptoms of a seafood allergy can vary from mild to severe and may include itching or hives, swelling of the lips, face, tongue, and throat, nausea, vomiting, abdominal pain, diarrhea, dizziness, shortness of breath, and anaphylaxis, a potentially life-threatening reaction that requires immediate medical attention.

A seafood allergy is typically diagnosed through a combination of a detailed medical history, skin prick tests, and blood tests that measure the presence of allergy-specific antibodies. An oral food challenge, under medical supervision, may also be conducted to confirm the diagnosis.

Currently, the only way to manage a seafood allergy is to strictly avoid the consumption of seafood and any products that may contain hidden seafood allergens. Always read food labels and be cautious when dining out, informing staff about your allergy. In the event of an accidental exposure, treatment options include the use of antihistamines and, in severe cases, an injection of epinephrine (adrenaline) to counteract the allergic reaction.

Oral immunotherapy (OIT) is an emerging treatment option for seafood allergies. It involves the gradual introduction of small, controlled amounts of the allergen under medical supervision to increase the individual’s tolerance over time. However, this treatment is still in the experimental stage and is not widely available. Other desensitization therapies are also being studied, but there are currently no proven cures for seafood allergies.

When dining out, always inform the staff about your seafood allergy and ask about ingredient lists and potential cross-contamination risks. Many restaurants offer allergen menus or are willing to accommodate special requests. When purchasing processed foods, read labels carefully and look for advisory warnings such as ‘may contain traces of shellfish’ or similar statements. Be cautious with products that have vague or non-specific ingredient listings.

Yes, individuals allergic to seafood can obtain omega-3 fatty acids from alternative sources such as flaxseeds, chia seeds, walnuts, and omega-3 fortified eggs. Certain types of algae, such as chlorella and spirulina, are also rich in omega-3 and are safe for those with seafood allergies. However, always consult a healthcare professional or dietitian for personalized advice on meeting your nutritional needs while managing a seafood allergy.
