Food allergy is actually an abnormal response triggered by the immune system to food as if it is threatening. Food intolerance looks similar to food allergies. However, the difference lies in how each one of them affects an individual. Food allergy is extremely intrinsic and to an extent, affects the internal organs. 

On the other hand, food intolerance is less severe, mostly just affects the digestive system due to the inability to digest that particular food properly, leading to an upset stomach. Most of the people suffer from food intolerance only, but they confuse it with food allergy.

About ninety percent of all cases of food allergy are related to only eight types of food as per research statistics. These are milk, tree nuts, egg, peanut, soy, wheat, shellfish, and fish.

The Reaction:\

In order to understand how symptoms manifest, it is of utmost importance, in this case, to understand how an allergic reaction to food occurs. An allergic reaction is a bi-step process as discussed further.

Step1: On exposure to the food allergen for the first time, the body reacts abnormally and produces IgE antibodies against the perceived allergen. These circulate throughout the entire body with blood and attach themselves to basophils (found in blood) and mast cells (found in sites like the nose, lungs, throat, gastrointestinal tract, skin, etc.).

Step 2: The next time the body is exposed to a particular food allergen, it gets alert and alarms the tissue that releases histamine in large quantity. Depending on the site of release, allergy symptoms are caused, ranging from mild to severe to potentially life-threatening (for example, in anaphylaxis).

The time span for an allergic reaction manifesting into symptoms can vary between a few minutes to several hours post exposure to the food allergen. The site of mast cells for release of histamine greatly affects the location and timing of the reaction.

Who is at Higher Risk?

If a person has a family history of developing a food allergy, it creates even greater chances for him/ her to have the same or similar reactions. If both the parents have some kind of allergic reaction to food, it is very likely that the child would have that too.

Symptoms:

Symptoms of food allergies largely depend on the sites of mast cells that release histamines. It is possible that these sites are located in nose, ears, or throat leading to itching in mouth, having a trouble in swallowing and breathing, and swelling of lips and tongue. If the location is in the gastrointestinal tract, it may lead to vomiting, diarrhoea, and abdominal pain. If it is in the skin, it might lead to hives, itching, decolourization, pigmentation, worsened eczema, etc.

Cross Reactivity:

If a person has an allergy to a particular food, it is advisable to abstain from similar types of food. For example, if somebody is allergic to crab, he/ she should abstain from shrimp, crayfish, lobster, etc. too as they might also trigger the reaction. This is called cross reactivity.

Treatment:

It is always advisable to abstain from foods which cause an allergic reaction in an individual. However, in case it has already occurred, there are two major types of medication which help in relieving the symptoms. Antihistamines are used for treating mild to chronic reaction, whereas adrenalines are used for severe reaction like in anaphylaxis.

Take Away:

Food allergy is usually a condition for life and cannot be permanently treated. However, symptoms can be relieved. Therefore, it is advisable to avoid the allergy, causing group of food.

Food Allergy - Everything About It!

Nuts are a rich source of energy but are also one of the most common food allergens. Both children and adults can suffer from nut allergies. While some children may outgrow the allergy, for others this is a lifelong condition. When it comes to children, the sibling of a child who is allergic to nuts also has a high risk of being allergic to them as well.

Nut allergies can be categorized as an allergy to peanuts or an allergy to tree nuts. Tree nuts are nuts that grow on trees such as walnuts, cashew nuts and almonds. Peanuts are not considered tree nuts as they grow underground in the form of legumes. A person can be allergic to both types of nuts but it is not necessary that if you are allergic to peanuts, you should avoid almonds as well and vice versa.

There are laboratory tests to determine the types of food you can be allergic to but in most cases, you realize you are allergic to something only after consuming it. Some of the symptoms of nut allergies include:

Redness
Rashes
Tenderness of the skin
Hives
Swelling of the hands and feet
Sneezing
Runny nose
Sore throat
Watery eyes
Nausea
Vomiting
Stomach cramps
Diarrhea
Shortness of breath
Most of the symptoms that affect the skin and respiratory system can be relieved with the help of antihistamines. Cold compresses can also help relieve itchiness caused by nut allergies.
One of the most severe forms of nut allergies can result in Anaphylaxis. This can be described as the swelling of the throat so much so that the airways are blocked and it becomes difficult to breathe. It is often accompanied by swelling of the facial features and itchiness. The only way to relieve this swelling is with an adrenaline injection. This reduces the swelling and reopens the airways. The most common type of adrenaline injection is known as an epi pen.

Some types of foods that commonly contain nuts and should be avoided include baked goods, pesto, nougat, marzipan, soups, multigrain bread, honey, granola, sauces such as hot sauce and barbeque sauce, salad dressings and veggie burgers. Nuts are often also used as thickening agents and hence if you know you are allergic to nuts, pay attention to food labels before you buy any product and make it a habit to tell your server in a restaurant that you are allergic to nuts.

Nuts - How To Know If You Are Allergic To Them?

A runny nose, Itchy rash, red eyes and shortness in breath are the most common allergic phenomenon which annoys you in frequent intervals, generally driven by several conditions due to hypersensitivity of the immune system towards something usual prevailing in the environment which may not cause any threat to others.

10 Foods That Help You Fight Allergies

Pollen is a common trigger for seasonal allergies. It may manifest as runny nose, cough, sneezing, stuffy nose, swelling around the eyes, etc. People begin to feel the bite of pollen allergy during spring when pollination in plants begins.

Pollen allergy affects a vast majority of people, and over-the- counter allergy relief medication is big business. However, it must be noted that there is hardly any permanent cure for pollen allergy. Nevertheless, there are ways in which one can get relief from the symptoms.

What Is Pollen and How Does It Cause Allergy:

The microscopic granules contained in flowering plants are known as pollen. While almost all flowering plants have pollen, all of them don t cause allergies. Plants that have bright flowers can hardly trigger allergy symptoms. It is the tiny and dry pollen that comes from trees, weeds, and grasses that precipitate the symptoms. These granules blow in the wind and get into the respiratory system. This precipitates an immune reaction which produces histamines. These are the chemicals that cause sneezing, stuffy nose, itching, runny nose etc.

Pollens can traverse distances of up to about 100 miles from the source. Since different varieties of plants, trees and weeds pollinate at different times, the season of pollen allergy is quite an extended one. It calls for precautions to prevent allergies and medicines and means to counter the effects.

Pollen Allergy Relief:

Allergy medicines are the best way to get relief from allergy symptoms. Doctors suggest starting on these medicines even before the onset of pollination season. These medicines are known as Antihistamines, which counter the effects of pollen.

These medicines block the histamine receptors in the ear-nose-throat region and thereby nullify the effects of pollen. If a person continues to take antihistamines throughout the pollination season, he/she deny the histamines a chance to get attached to the receptors and precipitate symptoms.

However, if a person is already suffering from the symptoms, antihistamines will not be able to quickly stop the problem. It will also not be able to reverse the effects of allergies. However, it can surely prevent exacerbation of symptoms.

Doctors also suggest using nasal corticosteroids for at least two weeks before pollination season so that the symptoms can be kept at bay. They work by modulating the response of the immune system and thereby preventing the release of chemicals that trigger allergies. If people take these medicines before exposure to pollen, they may even stabilize the immune system and prevent it from reacting to pollen.

Quick Allergy Relief:

If a person has not been proactive enough to take allergy medicines before the onset of pollination season, one needs to fight out the symptoms. However, there are some home remedies that can help a person put up a good fight with the irritating symptoms. One can do regular nasal irrigation with saline water several times a day throughout the pollination season to get some relief from allergies.

Conclusion:

There is hardly any perfect treatment for pollen allergy. However, one can stay safe with antihistamines or corticosteroids starting before exposure to pollen. In case a person gets attacked by these pollen allergies, seeking an immediate help is always advisable and recommended. Following the preventing instructions will help a person to fight against these allergies.
