According to data provided by the Mayo Clinic, there are about two percent of adults that experienced some form of food allergy at some time in their life. Additionally, kids with food allergies account for about another six percent of the population. When you consider that the combined adult and child population of America is over 3 hundred million, these apparently low percentages correspond to about six million grownups and 18 million minors.

Much the same as other allergic reactions, a food allergy comes about when the immune system overreacts to an allergen. Common food allergens include, but are not limited to, dairy products such as cream, seafood, shellfish, peanuts and eggs.

Because the body sees the intake of any of these foods as a foreign invader instead of nutrition, it releases an antibody called Immunoglobulin E or IgE for short in order to fight the perceived invader. The antibodies cause the release of histamine, prostaglandins and other compounds that produce the symptoms.

When compared with other allergic reactions, symptoms of food allergies are normally much more comprehensive. Sinus congestion and watery eyes are a possibility. Nevertheless, they are more often accompanied with or overtaken by allergic skin hives (itchy red welts that form on the skin), swelling up of the lips, tongue or pharynx, wheezing, sickness and abdominal pain.

In extreme cases, anaphylactic shock can come about. This is a whole body or systemic allergic reaction known as anaphylaxis. It involves a dramatic decrease in blood pressure, contracted respiratory tracts leading to breathing difficulty, dizziness and several other serious symptoms. It comes on very fast and if left untreated, can ,in some instances, result in the death of the person. In the U.S, some 200 people a year die as a result of anaphylactic shock.

In some cases, food allergy reactions are localized. For example, some folks will experience a tingling feeling in their mouth after eating fresh fruit or vegetables. The cause is considered to be proteins much the same as those found in ragweed pollen.

Differentiating between a food intolerance and a food allergy requires a professional diagnosis by an allergist.

An allergy skin test can frequently discover whether or not an individual actually has an allergy to certain foods. This process involves taking a tiny extract of the suspected substance and inserting it just under the surface of the individuals skin. The skin is observed for approximately 30 minutes to note any swelling up or itching in response to the extract.

To be able to guage the quantity of IgE produced by the body when ingesting a particular food, it may be necessary for a blood test to be made although this does not always give a definitive answer.

An example of where the symptoms are similar but not the same as an allergy is lactose intolerance. This is caused by the genetic lack of a digestive enzyme that is required by the body to process cows milk safely.

Eliminating the troublesome food from the diet and surroundings is the first and best line of defense. Even though it is perhaps a simple response, an individual who has an allergy to egg based products should avoid ingesting such foods. The same applies to anybody that is allergic to peanuts or products that contain traces of them.

Because there is no cure yet for food allergies, avoidance is the best medicine. However, it is not so easy to avoid some substances, despite your best efforts and in that situation, symptom relief is available in the form of antihistamines. It’s also good to have available an EpiPen or similar device that allows allergy sufferers to inject a small quantity of ephinephrine in an energency situation. A serious attack of anaphylaxis can be kept at bay until professional medical help can be given.

Any allergy, from whatever media it might come from, begins with the same reaction. The body mistakenly assumes that an particle, whether it’s pollen, or in the case of food allergies, a food protein, as a harmful threat. The immune system then releases immunoglobin E, otherwise known as IgE into the bloodstream, triggering a chain of events that release histamines in the body to attempt to combat the foreign particle. A skin rash, runny eyes, sneezing, whatever the manifestations, they still have the same first steps.

Baby Food Allergies

A baby will typically have an adverse reaction toward a food product, and one can often easily see what these reactions are. An example of an intolerant reaction to a food product would be from lactose intolerance, where people who are intolerant cannot break down the sugar in dairy products.

Spotting Trouble Signs

The food being eaten can cause a potentially dangerous allergy in infants due to some reactions. A common example would be an infant having loose bowels after eating, and may even vomit the food in an effort to expel it from the body.
The throat may also close up or the lips and face may swell up. Rashes or hives and other unusual symptoms in the skin surface can be seen of infant’s skin. An intolerance is different than an allergy, and usually has more to do with intestinal trouble than reaction to any particular allergen.

How to avoid allergy troubles

When introducing a new food product to your infant, be sure to try only minute quantities at first so that you can see if there are any unpleasant reactions to the food, and afterwards you can slowly increase the amount you are feeding when there are no apparent reactions.

During the course of introducing new food to your child, you should be able to see as well if your child likes it. If there are no negative reactions present, then you can safely increase the quantity given to a normal level.

The timing of introducing new foods should also be considered, and you’ll want to feed your child with new food early in the day so that you still have ample time to take your child to the pediatrician during clinic hours and disrupt your baby’s daily routine the least.

Ninety percent of all allergic reactions come from just eight food sources, and they are common enough to be found in foods everywhere. These are the kind of food products that you’ll want to check up on for your child, just to make sure that
there is no reaction whatsoever.

Milk is one of the most common, and you should check with dairy products should there be an adverse reaction. Eggs are the second on the list of allergen foods. Peanuts and tree nuts are some common allergens right up to adulthood, and they’ll have to manage these allergies all their life.

Fish and shellfish allergies can be outgrown, however. Soy and wheat are the last two materials that round out the list, and children can often outgrow these allergies as well Having an allergic reaction is somewhat a bit of a bother, but with proper management, avoidance, or treatment, your child can outgrow these allergies, or manage to live with it at the very least.

Check up by an physician to make sure whether your child is allergic or not.

Allergic reactions occur in most people in one form or another. But among the most common types are food allergies, which cause adverse immune system reactions when you ingest a certain food protein. It can be as simple as peanuts, or even shrimp, but have the same basic principle of reactions.

How The Body Reacts To Allergens In Food

How much the body will react when exposed to a food allergen ranges from mild irritation to anaphylaxis, which has the whole body reacting to the allergen and even possibly causing death. Depending on the severity of your allergy, reaction to food allergens can occur from a few hours to even just a few seconds after ingestion of the food containing the allergen.

In some types of reactions, it may be that there is just some mild tissue swelling, being itchy and irritating at the most. Of course, the swelling varies, so it can also cause obstruction in the air tract and causing difficulty breathing.

Common Food Allergens

At over ninety percent of all causes of allergic reactions, the most common food allergens have the bulk of the attention given to food allergies. They are divided into eight materials, and individually they are common enough that a person having an allergic reaction to these food materials better stay away from them to avoid having to undergo treatment.

Being allergic to milk is pretty common, and so are peanuts, eggs, soy, and wheat to name some. These are found in everyday food products that a person allergic to them will have to pay careful attention to what he or she is eating to avoid having an allergic reaction. Among the many food products Seafood and shellfish are also quite common easier to spot out in everyday surroundings.

Diagnosis, Testing, And Treatment

If you suspect that you’re allergic to a certain food product, it would be best to consult an expert allergist. Your physician will be able to guide you in this area, and recommend someone you can go to. Tests can be conducted to see what kind of material you’re allergic to. One common testing method is the skin prick test to see if a person is allergic from the media being exposed below the skin. Another would be the blood test diagnosis for another type of allergen.

The final test type would be to have a blindfold test to see if the patient is allergic to the actual allergen or a placebo. This is usually conducted in the hospital setting where patients may be treated quickly if their reaction becomes severe.

Once a patient has been identified as having an allergic reaction to food products, several treatment options can be taken at this point.There is no cure if you’re allergic to a certain food protein, and most doctors agree that injections or allergy shots don’t work for food allergies.

The surest method for treatment of food allergies is avoidance, and with this you’ll just have to learn which food your allergen is present in, and avoid it. For accidental ingestion, epinephrine can be given to stabilize the patient’s system. Before you find yourself in this situation though, it would be best to make sure that you know just what to do before a
severe reaction occurs.
