Sometimes a feeling of uneasiness and discomfort occurs immediately after a meal. It is often thought that the result of a food allergy. In most cases, however, this feeling of discomfort is the result of the intolerance of some foods rather than food allergy. The difference in food intolerance and allergy is mainly realized through the difference in time scale and severity of symptoms.

To understand and diagnose the difference between the two is important. Symptoms of food intolerance can manifest within hours or even a day later. In the case of allergies, the onset is immediate and generally within an hour. Food allergy occurs when the immune system attempts to process a protein found in the food incorrectly, leading to an overreaction by the body and the production of certain chemicals. It is important to identify the allergen in question is causing the food allergy so that it can be avoided in future.

Some of the key symptoms that occur with food allergies are:

1. Skin rashes and itching
2. Severe diarrhea and vomiting
3. Stomach cramps
4. Swelling skin especially in areas of procurement, such as the eyelids, lips and inside the mouth
5. A runny nose and blocked nasal passages
6. Inflammation throat, trachea and larynx
7. Headaches
8. Fatigue and dizziness
9. Joint pain
10. Hives

These symptoms should be identified immediately as delayed treatment can lead to malfunctioning of the internal systems. Ingredient labels should be read carefully when buying food and when eating out it is always a good idea to check with the waiter at the restaurant about ingredients used to prepare a plate. Some patients are so vulnerable that doctors even advise them to carry self-injectable epinephrine pens, which can literally save your life during  a severe allergic reaction.

The foods below are five of the most allergic foods for people with food allergies:

1. Eggs
2. Milk or dairy products
3. Seafood and shellfish
4. Peanuts and cashews
5. Wheat

These are the foods which most common affect children and adults, and it is important to visit a medical professional as soon as you experience any signs of a food allergy. In cases of food intolerance, smaller degrees of similar symptoms may occur but usually disappear after a short time. In the cases of food allergies these symptoms even more pronounced and severe, and may also lead to severe breathing problems or diarrhea.

shellfishShellfish allergies are considered the most common cause of severe allergies in adults throughout the world. In addition, shellfish allergies is the primary allergy known to manifest for the first time at anytime during adulthood.

Shellfish and Iodine

Although many shellfish species may be rich in iodine, there is no scientific evidence that shellfish allergies raise the risk of developing or having an iodine allergy. Furthermore, it has never been proven that people with shellfish allergies need to take precautions to avoid iodine when undergoing medical tests.  Iodine is not related to the protein that causes shellfish allergies. However, some persons feel that they may have an iodine relative; because they are allergic to shellfish or are known to have an fish allergy.

Fish Allergy

Warning: trim() expects parameter 1 to be string, array given in /home/adiffere/public_html/ on line 120

fish allergyFish allergies are actually caused by a protein contained in the flesh of fish and even fish oils and gelatin may trigger allergies if they have been contaminated by the proteins from the fish meat. The most common fish allergy reaction to a fish allergy are similar to other food allergies  effecting the skin, digestive system, and respiratory system. Specifically, there could be presence of urticaria (hives), eczema, and angioedema (swelling), itching, upset stomach, loose stools, vomiting, cramps, gas, vomiting, nasal congestion, shortness of breath, wheezing, asthma, heart burn, lightheadedness, or fainting.

Many people who cannot eat fish can consume shellfish without an allergic reaction and vice-versa.  The most common symptom of a fish allergy is considered to be ‘oral allergy syndrome’, which the mouth and lips may tingle or swell after eating fish or fish containing products. Fortunately, fish is usually not a ‘hidden ingredient’ in food.

Many people are concerned about an allergy to fish or shellfish and iodine. However, fish or shellfish allergy sufferers do not need to worry about cross reactions with iodine.

Preventing Fish Allergies

  • When dining out or eating foods prepared by others, extra precautions should taken.  If needed, check if the chef uses the same skillet to cook both meat and fish.
  • Watch out for condiments, sauces, or dressing that may contain fish proteins which may include worcestershire sauce, bouillabaisse, fumet (fish stock), caviar, roe (fish eggs), or imitation seafood often used in sushi.
  • Most omega-3 supplements can cause a allergic reaction and should be avoided.
  • Avoid all foods containing fish gelatin or anchovies and surimi (imitation crabmeat) which contains white fish.
  • Fish protein may become airborne during cooking and can create an allergic reaction.
  • It is possible to have a allergy reaction by walking through a fish market.

Healthy Food Choices for Fish Allergies

Oyster Allergies

I have become allergic to oysters. What can I do about it or should I just avoid them?

Best Answer:

An oyster allergy is less well known than other seafood allergies. As other shellfish related allergies, symptoms can range from mild such as oral allergy syndrome to the severe such as anaphylactic shock. Seafood related allergies are the most common of all food allergies worldwide.

The technical term for oysters are bivalve molluscs and an allergy to oysters is also associated with allergy to other bivalves such as clams, mussels, and scallops.  If someone has been diagnosed with an allergy to one mollusc, they will usually be advised by their physician to avoid all molluscs. It is interesting to note that people with a known allergy to shrimp can usually consume molluscs without reaction. However, there are rare cases where an individual is allergic to both types of shellfish. Furthermore, persons which are known to be allergic to finfish (such as cod or salmon) do not generally have allergies to shellfish.

All shellfish allergies are primarily due to an individual’s reaction to tropomyosin, a protein present in shellfish.  Symptoms of a oyster and shellfish allergy are:

  • Urticaria (hives) and angioedema (swelling)
  • Urticaria (hives) of the hands from handling seafood
  • Asthma
  • Vomiting, looses stools and abdominal pains
  • Mild to severe Atopic Eczema
  • Anaphylaxis leading to the possibility of death
