Quite a number of people suffer from allergic reactions. There are countless of possible allergens and they can bring about the onset of symptoms when one develops a reaction. One of the conditions in which many people suffer from is food allergies. With food allergies, one has a hypersensitivity to food, or one of its components.

An allergy is a severe reaction of the body’s immune system. The immune system goes into overdrive when there is a perceived threat to the body. In this case, the body perceives an ingredient in the food, like protein, as potentially harmful and goes all out to attack this ingredient and you, in the process.

When it comes to symptoms of food allergy, different people may have different set of symptoms. However, most of them will feel a swelling of tongue and throat along with having a tingling sensation in the mouth. Difficult in breathing, vomiting, diarrhea, drop in blood pressure and abdominal cramps may also be experienced by some people. Here, it is essential to mention that severe allergic reactions can cause death because they can affect cardiovascular system as well.

Food allergies happen when a person’s immune system believes that something he or she ate is harmful to the body. In an attempt to protect the body, the immune system produces antibodies, called immunoglobulin E (IgE), to that food. Those antibodies then cause mast cells (allergy cells in the body) to release chemicals, one of which is histamine, into the bloodstream.

An allergic reaction can be manifested in different ways and in varying intensities in different people. Some allergies may show obvious symptoms while others may not. Some people may react immediately once exposed to the allergen while in other people, it may take several hours for the symptoms to be manifested.

There seems to be about eight food allergies found. These foods include peanuts, milk, eggs, tree nuts, soy, wheat, and fish and shell fish. Each of these food allergies can be life threatening if not treated immediately. In addition, there are also people with allergies to fruits, vegetables and even seeds. Some of these common food allergies are seen most often in children.

So what is a food allergy sufferer to do? The first course of action is to educate themselves on labeling practices. Knowing where to look in a label for allergen information is a good first step. Avoiding foods that are labeled with the allergen is the primary method of treatment, since there is no cure for food allergy. Next, the food allergy sufferer must learn about ingredients that could contain allergens. For example, milk protein can appear under many labels and milk protein allergy can be caused by casein and whey.

Food allergies often result in food cravings. This seems to be a controversial statement but it is a fact accepted by medical establishment. This kind of allergy is called type B allergy and means food intolerance. Such intolerance can lead to weight gain, bloating, fatigue, water retention, etc. Some foods we crave will not necessarily make us fat, but others can be major contributors to weight gain.

Allergy gets into a body when an immune system becomes suddenly abnormal to a specific material which is generally not detrimental to most of the individuals except the one who has the allergy. When this allergy is triggered by an allergen or substance, the body recognizes this as a trespasser and releases any sort of chemicals so that it fights the trespasser causing symptoms like irritation. Moreover this irritation could also be fatal leading to death.

Allergy caused by food is a reaction which is made by the immune system. In the immune system antibodies are produced because of negative effect to few foods. Even though there are a lot of people who say that they have the allergy, only few actually have this allergy causing reactions. Many individuals confuse food allergy and food intolerance. Intolerance to certain kinds of food doesn’t affect the immune system. But both food allergy and intolerance are sensitivity reaction to foods.

In today’s world the medical department hasn’t found any proper cure for allergies caused by food. The allergy management only cautions you of intake of the allergens in food and few diet modifications.

During the allergic reaction, Antibodies are released by the immune system, especially immunoglobulin E. It inevitably causes the production of histamine (chemical) in the way of guarding the body. The following chemicals are the main cause of symptoms that includes irritation in eyes, throat, skin, gastrointestinal organs and lungs. These things happen when one is exposed to allergen.

There are 8 major foods that are the main cause for the reaction (allergic). These eight allergy provoking foods are soy, wheat, fish, milk, eggs, tree nuts, shellfish and peanuts.

These cause severe damage to an individual’s body.

People afflicted with allergies react to only certain allergy causing foods. Cross reaction takes place when allergy to a kind of food causes (allergic) reaction to foods that are related to allergen food. For example, a reaction to wheat could cause a reaction to rye.

The Allergy in pollens could cause allergy to peaches, almonds, hazelnuts, green apples. Reaction to a goat’s milk could be cause an allergy to cow’s milk. So there are so many examples to show cross reaction.

If you accidentally ingested the food-containing allergen, it is very important that you should immediately take anti-histamine medications. This is why you have to take anti-histamine medication wherever you go in case you accidentally ate food that contains an ingredient that you are allergic from.

These are some of the common food allergens that you should know about in order to properly manage it and minimize the risk of future allergy attacks that can lead to severe discomfort and in severe cases, death.

Asthma or eczema patients could be at a risk of having food allergy. To add to this they might be having a severe reaction than the normal people who have only food allergy. This is because, when an allergy occurs, the concerned person is under stress which could lead to triggering their eczema or asthma aggravating the current situation. But the degree of this reaction depends upon circumstances like a person’s sensitivity threshold to allergen, exposure scale the individual has to the food and the quantity of eaten food.

Vigilance and self-discipline will help or guide a person who suffers from this allergy. There are no specific cures for the food allergy. However contacting your physician will serve you better responses. The physician will understand your problems and give you proper treatment.

Food allergies happen when your immune system messes up. Your immune system is supposed to protect you from disease and germs. If you have a food allergy your immune system makes a mistake and thinks the food is going to harm you.

The response is the same whether it is a food allergy, an allergy to medicine, an allergy to a flower or tree, or an allergy to peanuts. Although the foods themselves are not harmful the reaction the body has can be life threatening.

In recent years we have heard a lot about the peanut food allergy mainly because the reaction is usually very severe leading to anaphylactic shock.

Here’s what can happen if a child or adult for that matter eats a peanut topped brownie which they have a food allergy to – the antibodies in the body over react releasing histamine in the blood.

The histamine released eyes, throat, nose, respiratory, skin, and even the digestive system can be affected by the food allergy. The reaction could be mild or severe and it can happen almost right away or a couple of hours later.

Some of the first signs of a person suffering from a food allergy can be a runny nose, hives, itchy skin, tingling lips or tongue. Other signs can include tightness in the throat, hoarse voice, coughing, wheezing, stomach pain, diarrhea, and nausea or vomiting.

And with a serious food allergy anaphylaxis occurs which is a severe allergic reaction that comes on suddenly and with several serious problems all occurring at once – the heart, digestive system, respiratory all react at the same time and the breathing tube narrows while the tongue swells making breathing difficult if not impossible – this is a medical emergency.

If you have a serious food allergy and not necessarily to peanuts you need to make sure you know exactly what you are eating. If there is any doubt don’t eat it. You might also carry the proper medication with you.

Kids often suffer from milk and eggs but the often will outgrow these. Severe allergies are commonly seen in peanuts, shrimp, and fish and these do not usually disappear with age.

Not sure how to tell if you have a food allergy? Sometimes it’s pretty easy to figure out. Hives may appear or perhaps stomach problems occur. But other times it’s harder to tell. And sometimes even if you know you have a food allergy determining to what can be really difficult.

Many medical professionals believe that allergies are genetic and inherited so if you have a parent that suffers from hay fever you can expect to do so yourself. Food allergies can resolve themselves over time.

It is important that you do not confuse a food allergy with food intolerance such as with lactose intolerance which can cause severe stomach pain and diarrhea. But that doesn’t make it an allergy.

For some food allergies it’s as simple as not eating the food anymore. Other food allergies are harder to diagnose and harder to avoid. You should see a doctor that specializes in allergies. The doctor will ask you a lot of questions to help determine if you have a food allergy.

A liquid extract of the food or foods that are suspect is used to determine the food allergy. A tiny scratch is made on the skin and then a drop of the extract placed on the scratch. The doctor will watch for the development of a red spot which will indicate you have a food allergy to that particular food.

Once a food allergy is determined the doctor will decide on the best course of action and whether treatment is needed. Once you know what your allergy is it becomes much easier to deal with.
