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 trigger allergies
Some of the common foods that trigger allergies are:
1. Peanuts
2. Shellfish
3. Other forms of tree nuts such as almonds, walnuts etc.
4. Gluten rich grains such as wheat, rye barley, oats
5. Certain types of fish
6. Eggs
7. Soy products
8. Milk (allergic reactions mostly occur within children)

Some other foods which have been known to cause allergies in rare cases are:
1. Meats such as pork, chicken, beef, mutton
2. Corn and corn products
3. Gelatin
4. Certain spices such as mustard, garlic and coriander among others
5. Certain seeds such as poppy, sunflower, or sesame

Symptoms of allergies
In certain cases, the allergies might manifest immediately, almost in a matter of minutes, within the body. However, in many cases, it may take a few hours for it to show up. The symptoms may range from mild to quite severe. Mild symptoms will make it quite hard to actually diagnose it as a food allergy.

Some of the milder symptoms could be:
1. Hives or eczema could form on your skin which may be very itchy. These would look like raised swollen areas that could be red, inflamed, and dry.
2. The inside of your mouth and ears may become itchy
3. You could suddenly develop a runny or a blocked nose and start sneezing or coughing.
4. Your eyes may become watery, red and itchy
5. You may develop a funny taste in your mouth
6. Others symptoms may include throwing up and even loose motions

Other severe forms of allergies can be caused mostly by shellfish and peanuts and other forms of nuts and fish. Symptoms in such cases would look like:
1. Uneven heartbeat
2. Difficulty in swallowing and breathing
3. Feeling of extreme weakness, confusion
4. Passing out or feeling light headed
5. The tongue, throat or lips may swell up
6. Chest pain

Common Foods that Can Trigger Allergy

Food allergies have been on the rise and many food items have been identified as potential allergens. Common items like citrus fruits, coconut, peanuts, tree nuts, gluten can cause allergies. You don't need to stay away from your favorite dish just because it contains one of the allergy-causing ingredients. You can customize your dish with suitable substitutions and enjoy your food without worrying.

Peanut

Peanut is one of the most common allergy-causing items. It has severe effects on people who are allergic to it. On its consumption, the throat of allergic person swells up, blocking the airways which can lead to anaphylaxis. So, for people who are allergic to this grain legume, peanut -laden cuisines like Thai food, peanut butter, and jelly are all prohibited. But you can replace peanut with sesame seeds, pumpkin seeds, and hemp which are available in butter form as well.

Citrus fruits

Lime, orange, lemon, and grapefruit have been seen to cause discomfort in both adolescents and adults. There are so many citrus-flavored drinks that it becomes difficult to find a nice harmless drink. But, if you are allergic to these fruits you can go for strawberry, raspberry, and apple-flavored drinks, which are easily available.

Coconut

Coconut is used in place of milk in vegan recipes; it can replace milk in food items like ice cream, sweet drinks, and curries. If you are allergic to coconut, substitute it with rice, soy, oats milk and even soaked cashews.

Wheat

Wheat is not only off limits to people with celiac disease who have to lead a gluten free life but for some who are allergic to wheat specifically. Pasta, bread and many other kinds of foods are made up of wheat, but you can opt for tapioca or rice flour which is also used to make such items.

Best Substitutes for Common Food Allergens

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!

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.

Pollen Allergy - How To Get Relief From It?

Every year, the emergency rooms at hospitals get flooded by cases of allergic reactions from food. According to a census, about 15 million Indians suffer from some kind of food allergy. The symptoms of food allergy may vary from itchy mouth to potentially fatal conditions like anaphylactic shock. Other symptoms of an allergic reaction can present themselves as difficulty in breathing, swelling of the tongue, rashes and intestinal discomfort.

According to specialists, allergies to food can develop at any age, at any time. Hence, if you suspect a sudden allergic reaction to a food that you have consumed before without any problem, it is advised to consult your doctor.

Here is a list of the most common food allergies that people suffer from frequently-

MILK: Milk is the most common food that children and infants are allergic to. Milk allergy must not be confused with lactose intolerance wherein a person faces many difficulties in digesting the sugar present in milk. The two conditions are not related. Milk allergy is the hypersensitivity reaction that happens in response to certain proteins present in milk and can be potentially deadly. Most children are seen to outgrow their allergy to milk.
WHEAT: It is a common misconception to confuse Celiac's disease with a wheat allergy. Wheat allergy exclusively occurs due to the hypersensitivity to the protein present in wheat alone. In Celiac's disease, it is the gluten in the food they are hypersensitive to, which is also present in rye, barley and oats.
SOY: Soy is a very common allergic food and most children seem to outgrow it by the age of 10. Most of the time, soy allergy is not too severe and the symptoms presented are mostly mild. Although, cases of anaphylaxis in reaction to soy have been reported. Soy and soy protein are very common ingredients found in food, hence it is advised to check the ingredients present before consuming it.
SHELLFISH: This allergy usually does not go away and you are most likely to deal with all your life. Most people who experience allergies from shellfish are most likely to be hypersensitive to both crustaceans (lobsters, shrimps and crabs) and mollusks (mussels, oysters, scallops and clams). This type of allergy can become very intense and you must even avoid the steam produced from cooking shellfish. For some people, the mere contact with shellfish can trigger an allergic reaction.

4 Most Common Food Allergies

What is allergic rhinitis?

Allergic rhinitis is defined as allergic symptoms in the nasal passage. Allergic rhinitis can be seasonal (occurring during specific seasons) or perennial (occurring year round). The allergens that most commonly cause seasonal allergic rhinitis include pollens from trees,grasses and weeds, as well as spores from fungi and moulds. The allergens that most commonly cause perennial allergic rhinitis are house dust mites, cockroaches,animal dander,and fungi or moulds. Perennial allergic rhinitis tends to be more difficult to treat.

How does allergic rhinitis occur ?

This condition occurs when allergens (allergy- causing substances) come into contact with the nose, and usually also the ears, sinuses, and the throat. When allergens come in contact with the lining of the nose and sinuses, they trigger the cells to release the chemical histamine, which causes the allergy symptoms described below.

What are the symptoms ?

Nasal congestion 
Sneezing 
Watery " runny nose" 
Itchy eyes,nose,or throat 
Puffy eyes or 'allergic shiners'
Post nasal drip 
Tears 
These symptoms may occur during a certain season or year long. They can occur at any age. 

What is the treatment for allergic rhinitis ? 

A number of medications ,including antihistamines, intranasal corticosteroids, and decongestants are available to control symptoms. Allergen immunotherapy could provide long lasting benefit. You can "train" your immune system not to react exaggerated to an allergen anymore.
