What you need to know about sardine allergy

Sardine is basically a type of fish that are commonly canned since they are perishable but can be eaten fresh. An allergic reaction to sardines is uncommon but can occur among a small percentage of individuals who also suffer from seafood allergies. The signs and symptoms of an allergic response to sardines tend to vary from one individual to another. If an individual experiences a severe allergic reaction that results to the swelling of the throat and airways, it is important to seek immediate emergency care.

What are the health benefits of sardines?

Sardine has been recorded to promote cardiovascular health, bone health, weight control as well as the prevention of cancer, diabetes and inflammatory diseases. Take note that it contains large amounts of omega-3 fatty acids. These fatty acids help reduce the cholesterol and triglyceride levels, thus minimizing the risk for blood clots, hardening of the arteries as well as heart attacks. Sardines are also a good source of vitamin B-12 which reduces the risk for atherosclerosis. Additionally, the omega-3 fatty acids also minimize the risk for inflammatory diseases and cancer. Do not forget that the high levels of calcium, vitamin D and phosphorus present in sardines helps promote bone health and prevent osteoporosis.

Allergic reaction to sardine

The respiratory symptoms include itchy eyes, swelling of the airways, sneezing, tightening of the chest and difficulty breathing.

It is important to note that an allergic reaction to sardine is believed to involve the protein, parvalbumin which is present in all species of fish. The protein is capable to survive under heat, thus eating cooked sardine will not minimize the risk for an allergic reaction. An allergic response can be initiated by eating sardines, inhalation of the vapor while being cooked or served or direct exposure to the skin or mucous membranes. The immune system identifies the protein as a threat and triggers an IgE-mediated immune response. As a result, histamine is released and triggers the manifestation of the symptoms of an allergic reaction.

Indications of an allergic reaction to sardine

Take note that aside from the histamine that is released by the body, canned sardines are comprised of high amounts of histamine. The histamine that is present in canned sardine accumulates during the fermentation process, canning process and when the sardine decomposes. The high concentration of histamine will increase the severity of the symptoms of an allergic response. Oral allergy syndrome which involves the swelling and itching of the lips, mouth, throat and face can be observed within a few minutes up to a few hours of ingesting sardine. As for the skin reactions, it includes itching, swelling and inflammation as well as the development of hives and eczema. The respiratory symptoms include itchy eyes, swelling of the airways, sneezing, tightening of the chest and difficulty breathing. In severe cases, the individual can suffer from a life-threatening reaction called anaphylaxis. If the individual experiences diarrhea, nausea, fainting, heart palpitation and difficulty breathing, immediate medical care is required. Always remember that being prepared is a must when a severe allergic reaction occurs. With this in mind, it is time to enroll for first aid training in Vancouver today.
