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

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

The number of allergens are many and knowing what triggers your allergies can get complicated. The common triggers that are known to trigger allergic rhinitis are:

Moulds
Fungi
Pollen, the most common cause for allergies
Dust mites, and the faeces of dust mites that can cause severe allergic reactions
Cockroaches
Animal dander, which includes cat hair, dog fur, and may also include little flakes of skin
Avoiding the above mentioned triggers is more of a general guideline for the management of allergies. The lifestyle changes that you make to manage allergies:

Keep yourself hydrated at all times. Drink about eight to ten glasses of water every day. This will allow the mucous to be expelled with ease, if you experience any nose block.
During seasons like spring, when the amount of pollen in the air is at its maximum, limit your exposure. Try to stay indoors to avoid exposure to pollen or dust in the air.
Make it a point to take a shower before going to sleep as the residues of pollen and dust stuck to your skin are likely to make your symptoms worse.
Use fresh bedding and clothes every day. This will help to reduce your exposure to allergens.
Remove your carpets. Carpets are home to dust mites and pollen grains which become difficult to remove even with vacuum cleaners. Remove the carpets during the allergy season, and replace with hard flooring.
Keep windows and doors shut to avoid dust and pollen grains from entering the house and possibly causing allergies.
Avoid staying around pets. It that is not possible, then wash them at least once a week to reduce allergies.
Prevent inhaling cigarette smoke or smoking cigarettes. The smoke can be very harmful and can increase the risk of asthma in kids.
Avoid outdoor trips during seasons when the pollen count is high.

10 Foods That Help You Fight Allergies

Can Food Allergies Be the Likely Cause of Your Infertility?

Infertility in a woman refers to the inability to conceive after having regular unprotected sex. Cases of unexplained infertility have been on the rise recently.  Though obstructed fallopian tubes and ovulation disorders are some of the common causes of infertility, reasons pertaining to dietary changes can also be responsible. Food allergies and dietary changes affect infertility to a great extent; and if you're struggling with conception or infertility, heeding to your diet can help.

Below is a list of diet constituents that are likely to cause infertility.

1. Gluten - Gluten is a protein found in grains like wheat, rye, and barley. Among the general population, women suffering from unexplained infertility have a higher incidence of gluten intolerance. Gluten intolerance is also related to miscarriages, and if left undiagnosed can lead to malabsorption of micronutrients like iron and zinc. Following and maintaining a gluten-free diet may relieve a sufferer from the symptoms. Try and include gluten free cereals like rice, corn and gluten free oats to manage the situation.

2. Inflammation - Another connection of food allergies and infertility would be inflammation. Inflammation occurs when the food allergens reach the stomach. This inflammation, if heightened, can cause damage to the fallopian tubes and the ovary. The body responds to the food allergens by treating it like a foreign substance that needs to be eradicated, and when your immune system is subjected to chronic inflammation, it can lead to infertility.

Additionally, apart from food allergies, even the consumption of certain foods and beverages can be a reason behind infertility, with those being rich in caffeine being a major cause. Increased consumption of caffeine can augment the risk of infertility and delayed conception. However, avoiding caffeine and eliminating problematic foods along with a careful scrutiny of your diet can increase your chances of getting pregnant.
