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!

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.
    Add Spices: Add spices to your cooking such as turmeric or garlic as they help in rejuvenating the respiratory system.

Seasonal Allergies - 6 Natural Remedies That Help you Manage them

Your child is fond of nuts and has eaten a chocolate with nuts but shortly after that develops a skin rash and starts to itch. The rash may even spread to the surrounding area. This is an indication of food allergy to nuts.

What happens is simple - the body's immune system recognizes specific proteins in the food as harmful (antigens) and produces antibodies which can combat them. This leads to an allergic reaction which can vary from something as simple as a skin rash to severe breathing issues.
Though any child can develop food allergies, in most cases, there is a strong hereditary linkage. If parents have had a history of allergy to certain foods, then there is a strong likelihood that the child could have that food allergy too.

Some of the common foods that can cause allergies are as follows:
1. Cow's milk
2. Eggs
3. Nuts (peanuts, walnuts, pecans, cashews or hazelnuts)
4. Soy
5. Wheat
6. Fish (salmon, cod and others)
7. Shellfish (lobsters, shrimps and others)
Of these, peanuts, seafood, and milk are the most common food stuffs that lead to allergies.

Because the child is yet to realize that he has eaten something that his system will not readily accept, the allergic reaction can be described in various ways, as below:
1. Scratching or itching on the tongue
2. Change in the voice - can become husky or hoarse
3. Burning of the tongue
4 tingling of the tongue
5. Funny feeling in the mouth
6. Feeling of something stuck in the throat
7. Itchy feeling or bugs in the ears
8. Throat going thick
9. Bump on the back of the tongue

These are some ways that a child can describe his allergic reaction. Some of the mild symptoms of a food allergy are as follows:
1. Hives (red, swollen, itchy areas on the skin)
2. Eczema of the skin (dry, itchy rash)
3. Nasal congestion
4. Sneezing
5. Itching of the tongue and the mouth
6. Nausea or vomiting
7. Stomach pain

Severe symptoms include:
1. Severe swelling of the lips and tongue that can block breathing
2. Inability to swallow
3. Difficulty breathing
4. Turning blue
5. Dropping of pulse
6. Drowsiness

As the parent identifies a similar reaction when eating the same food item, they can suspect allergic reactions and immediately reach out to the doctor. A detailed discussion will help establish the causative agent. Once that is known, then avoiding food allergies is quite easy. In fact, a well-informed child will know that avoiding certain foods is very beneficial. This will improve the quality of life of the child, help avoid missing school due to allergic reactions, and help avoid the child (and the parent) suffering.

How to Know if Your Child Suffers From Food Allergy

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?

In reality, dust allergy is precipitated by dust mites, a kind of microorganisms that thrive in dust. They acquire their food from dead skin cells and absorb water from the environment and thrive. Moist and warm environments are ideal for them to thrive. However, they themselves don t cause allergic symptoms. 

It is the response of the immune system to them that precipitates the symptoms. Once they are inside the human respiratory system, the immune system responds to them in a negative way. This leads to the production of histamines, a kind of protein that abates swelling, cough, mucous production, runny nose, sneezing, etc.

Symptoms of Dust Allergy:

Dust allergies may lead to various symptoms, some of which may be short lived, while others may be chronic. Some of these symptoms may also be life threatening. While in general people may suffer from running nose, stuffy nose, sneezing, coughing, itchy eyes, postnasal drip, swollen skin under the eyes, etc., in severe cases, people may also suffer from asthma, chest pain and tightness, trouble in sleeping due to shortness of breath, bouts of severe cough, sinus infection, etc.

Risk Factors:

Some of the common risk factors are: 

Family History: People who have a family history of dust allergy are most susceptible to this problem. These people develop a sensitivity to dust mites.

Exposure: Exposure to dust mites is the main cause of dust allergy. If someone is exposed to dust mites for a long time, it enhances the risk of allergy symptoms.

Being a Child: Children are more susceptible to it than adults. They are more likely to develop allergies during childhood and early adulthood compared to adults.

Diagnosis:

Most dust allergy symptoms are similar to common cough and cold symptoms. This is why it is necessary to confirm that the symptoms owe their origin to dust allergy. As a primary physical examination, the doctor may examine the lining of nasal passage to see if it is swollen.

In case the person is allergic to dust or pollen, the lining of the nasal passage is likely to become inflamed. However, the doctor also needs to conduct some tests. He may conduct skin tests and blood tests to confirm the allergy. If the allergy is confirmed, the doctor goes for treatment.

Treatment:

There are a number of treatment options for dust allergy. Some of these may act as over-the-counter to counter the effects of dust allergy, while others may act as modulators to modulate the immune response.

Antihistamines: These are medicines that counter histamines responsible for allergic reactions like itching, runny nose, sneezing, etc.

Corticosteroids: Corticosteroids are usually delivered through nasal sprays to bring down inflammation and control the allergic response of the immune system.

Decongestants: They help to decongest nasal airways which get inflamed and swell up due to allergic reactions.

Leukotriene Modifiers: These medicines block certain immune system chemicals responsible for allergic reactions and prevent allergic reactions.

Immunotherapy: The doctor may go for immunotherapy if no other effort is yielding any results. This therapy trains the immune system so that it does not become sensitive to dust mites. It is delivered via injections.

Conclusion:

The primary defense against dust allergy is avoiding breathing in dust. However, if a person is already exposed to them, there are a number of medicines and treatment options to prevent a flare up.
