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!

Food is a very important part of your life as it provides all the necessary nutrients required by your body and is essentially, the fuel for all things to function within. However, many people may have aversion to certain kinds of food as it causes adverse reactions within their body. Let s look at some of the common food allergies that people commonly report and how to identify them.

Allergies v/s Intolerances: It is important to note here that there is a significant difference between food sensitivities or intolerances and allergies. Sensitivities or intolerances cause adverse effects on your body inevitably when you consume certain types of foods. One such example is diarrhea, caused by ingesting cheese or milk by lactose intolerant people. However, allergies are caused when the immune system within your body mistakes harmless food as something that might harm you and thus tries to protect you from its effects. This results in reactions within your body which may be very painful and problematic.

Common Foods that Can Trigger Allergy

An estimated 10 to 30 percent of people across the world suffer from Allergic rhinitis. Allergic rhinitis, more commonly known as hay fever, is a condition wherein the immune system overly responds to allergens resulting in inflammation in the nose. As you might be aware, an allergen is typically a harmless substance present in the surroundings causing an uncomfortable allergic reaction.

Following is a detailed account of the condition.

Symptoms-
Some of the most common symptoms of allergic rhinitis include,

Sneezing
Stuffy and runny nose
Persistent coughing
Itchy and watery eyes
Sore throat
Frequent headaches
Dark circles under the eyes
And, symptoms associated with eczema
Further, it also results in hives and excessive fatigue. An allergic person is likely to feel many of these symptoms within a few minutes of coming into contact with an allergen. Some symptoms, such as recurrent fatigue and headaches can only happen when there is long-term exposure to allergens. There are some people, who rarely undergo any signs, and this happens when a person is exposed to the allergens in massive quantities.

Causes of Allergic Rhinitis:
When the body comes in contact with the allergen, it triggers the release of histamine which is a natural chemical that defends the body from the allergen. This histamine can lead to allergic rhinitis and the associated symptoms which may range from a blocked or a runny nose to itchy eyes. Common allergens include pollen, dust mites, animal dander, grass pollen, and mold.

There are two variants of allergic rhinitis- seasonal and perennial.

Seasonal- Seasonal allergies usually occur during specific seasons owing to the response to outdoor allergens. For example, during a specific time in the year such as spring, the pollen can cause allergies in a person. Also, when trees and flowers release pollens during the fall and summer, seasonal allergic rhinitis can be seen on the rise.
Perennial- On the other hand, perennial allergens tend to linger all-round the year, and pet dander, mold or dust mites come under perennial allergic rhinitis causing allergens.
Diagnosing and treating allergic rhinitis-
When a person is suffering from minor allergies, a physical exam may be required. But a doctor may also perform some tests for identifying the best course of treatment as well as prevention plan for a particular patient. A skin prick test is one of the best ways to determine whether you have allergic rhinitis.

This health issue can be treated in a variety of ways which range from home remedies to medications to alternative therapies. Common medications include antihistamines, decongestants and nasal sprays and eye drops.

Staying away from a known allergen is the best possible way to prevent allergic rhinitis. When diagnosed, it is necessary to consult your doctor as the condition may sometimes lead to complications.

Food Allergies - How To Deal With Them?

Seasonal allergies are usually characterized by sneezing, coughing and other allergic reactions. Also known as hay fever and allergic rhinitis, the condition tends to appear only during certain seasons of the year. The disease is triggered by changes in the weather and exposure to certain allergens like dust. The allergens cause the body to release histamine into the blood thus, resulting in symptoms of allergy.

The symptoms of seasonal allergy are:

    Coughing
    Sneezing
    Congestion in the nose
    You may experience a blocked and runny nose
    You may have an itchy nose

Ayurveda is a holistic method of treatment that focuses on improving your overall well-being. The various Ayurvedic remedies for treating seasonal allergies are:

    Restrict Dairy Intake: You need to cut dairy out of your diet as dairy products have all the characteristics of a cold food. They tend to create imbalance in the  kapha  dosha in the body, thus leading to various diseases.
    Ayurvedic Detox: Consider doing an Ayurvedic detoxification to cleanse the body of the various toxins. It helps in smoothing out the  dosha  balance and hence improves your overall well-being.
    Nasya: This process requires you to put drops of medicated oils inside your nostrils. This lubricates the nasal cavity and prevents the allergens from causing an allergic reaction in the body.
    Eat More Warm Foods: Try to eat warm and cooked foods as much as possible. Eating frozen foods is not recommended as the nutrients from the food may not be absorbed properly owing to a weak digestive system which may be the result of a bout of severe seasonal allergies. Include foods such as soups and porridge and you have a perfect dish to gorge on.
    Exercise on a Regular Basis: Make sure you exercise on a regular basis to improve your fitness levels and also to keep a check on your weight. Certain  yoga  poses such as the downward dog and the cobra help to improve the digestive process. Add cardio workouts such as running and swimming to improve the health of the lungs.
