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!

Over time, we have caused tremendous harm to our immune system. Day in and day out, we have potentially risked our lives by being so casual with our health choices. But still, is it possible to leverage some of this burden and thus make our immune system stronger? What if we incorporate some healthy habits into our daily regime? What if we improvise on our diet? Take certain additional vitamin supplements perhaps? Make other lifestyle changes in the hope of achieving a near-perfect immune system?

What exactly is the Immune System?

The immune system in layman language can be considered as a protective cover of the human health system. We are surrounded by millions of pathogens (disease causing germs) that have the ability to enter into the body and cause damage to it. Here comes in the importance of the immune system, the body s natural shield against these pathogens.

How can you boost your Immunity?

You definitely cannot evade all the pathogens and get a top-notch, impeccable immune system, but you can at least try and listen to what your body has to say, and take steps accordingly.

The first and foremost protective measure can be to follow certain general good-health guidelines.

Do not smoke. There can be no compromise on this issue. Smoking or consuming tobacco in any form brings about a host of health complications; the most pronounced of them all is probably cancer. Smoking, in more ways than one, can spell real trouble for your immune system. So better cut down on your puffs or gear up to face the various medical banes of smoking.

Eat a diet which is rich in fruits, vegetables, whole grains and low in saturated fat. Some examples may include citrus fruits, green leafy vegetables such as spinach or lettuce, yoghurt, almonds, lean meat. Sipping on green tea thrice a day is a wise choice in this regard. These measures not only strengthen the immune system but also enhance the Immune System.

Drink plenty of water. Water keeps the body hydrated, the ultimate prerequisite for a strong immune system. It helps to flush out all the toxins and ensures that the cells get the optimum levels of oxygen. Drinking a glass of lukewarm water mixed with honey and lemon on an empty stomach after getting up in the morning can prove to be one of the best health choices that you can make for your body.

If you drink alcohol, drink only in moderation. Excessive alcohol consumption causes dehydration and it can deprive your body of the valuable immunity boosting nutrients. It also impairs the body s ability to fight off germs and infections.

Get adequate sleep. One reason behind stressing on the need to get adequate sleep is because it s so closely linked to the immune system. While you sleep, the body secretes certain hormones and substances which help better fight infections and diseases. This makes these hormones so vital and indispensable at the same time. So now you know what wonders can those 8 hours of sleep do to you.

Exercise Regularly. If you're looking for a safe and smart way to boost your immunity, regular exercise is the answer to it. But we are not talking about being an ardent, hard-core gym-junkie; rather exercising in moderate amounts would suffice. Cardiovascular exercises such as walking or swimming, performed 30-45 minutes a day, can prove to be very beneficial.

Including good hygiene habits in your daily routine, such as washing your hands properly, bathing and brushing your teeth daily, etc. can be useful as well. Good sanitary habits can be the most basic way to ward off infections at the germination stage. Keep a hand sanitizer with you all the time.

7 Healthy Habits That Keep Your Immune System Strong

While some people look forward to spring and the beautiful flowers that bloom, for others this is a time of extreme discomfort triggered by pollen allergies. Pollen is probably one of the most difficult allergies to fight as it is invisible and is literally present everywhere. Sneezing, coughing, a runny nose, congestion and watery eyes are the most common symptoms of a pollen allergy. However, you can minimise your troubles by following a few simple steps.

Keep an eye on the pollen count: Not every day has the same amount of pollen in the air. Pollen density is also affected by the time of the day. Pollen count refers to the amount of pollen present in the air during a specific time period. You can find out the pollen count of your area online or through a number of apps. Once you know the pollen count. You can plan your day accordingly and step out or stay in.
Plan your time spent outdoors wisely: It isn t always possible to stay indoors even if you know the pollen count is high. However, you can still plan your time so as to not be outdoors at peak pollen times. 5am to 9am are the worst times to step out as this is when most plants pollinate. Hence avoid stepping out during this time. Windy days can also worsen the situation by spreading pollen around. If you must go for a jog early morning, avoid thoroughfares and gardens and instead pick a route around residential streets.
Protect yourself: Face masks may not look very good but can help reduce the amount of pollen being inhaled. If you find yourself sneezing a lot during pollen season, consider investing in a painter s mask that can filter the air being inhaled and exhaled. If you are stepping out to do yard work or know that you re going to spend a lot of time in heavy traffic areas, take your antiallergenic medication before you step out instead of waiting for an allergic reaction to begin.
Have plenty of showers: Try making it a habit to have a shower and changing your clothes as soon as you come home. This prevents the outdoor pollen from circulating in your home. Follow this routine even if you ve simply been gardening outdoors. While showering, do not forget your hair. If you do not want to shampoo it every day, simply rinse it out to get rid of all the pollen.

Pollen Allergy - 4 Tips To Keep Yourself Safe!

Air pollution is known to take a toll on the lungs of even the healthiest adults. So, it comes as no surprise that the effects of this pollution on the lungs of children is deemed as a grave situation, full of health hazards including the onset of Chronic Obstructive Pulmonary Disorders and conditions like asthma and other lung disorders. Read on to find out more about the link between air pollution and its effect on the lungs of children.

Children's Lungs: Mostly, all the organs of a child's body are considered delicate and not fully matured until the child reaches a certain age. The main and largest part of the child's lungs will usually grow only after the child is born, much like the arms and legs. In fact, it is a medically proven fact that about 80% of the tiniest of air sacs grow after the child's birth, these are called the alveoli and they facilitate the transfer of the oxygen into the bloodstream with a life-sustaining function that is built into our lungs. These alveoli continue to grow until the child becomes an adult. 

Immunity and Infections: Like the lungs of the child, the immunity of the child is also still in its growth phase, and is very much, unlike the immunity that an adult enjoys. This makes the child more susceptible to infections that are usually carried by air pollution in today's day and age of urban living when myriad pollutants are sent into the air every single day. Also, since children play outdoors more often and spend more time breathing in this air, they are more prone to these infections and lung or respiratory ailments due to this reason. Various studies and tests have shown inflammation in the respiratory passages caused by deposits of carbon dioxide emissions in the lungs of children.

Symptoms: Usually, the very first symptoms that show that air pollution is affecting your child's lungs can be seen when persistent coughing and wheezing sets in, without any proper reason. Also, when the child faces bronchial infections time and time again, all these are indicators of hazardous effects of air pollution in children.

Respiratory problems: Apart from respiratory problems, which can lead to asthmatic attacks, hay fever and allergies as well as other COPD ailments, there are other related dangers as well. These can happen when constant choking and obstruction of oxygen due to pollution becomes a regular affair. These include stroke and brain damage which can eventually also lead to a higher risk of dementia. 

How can you protect your child during such times?

Restrict outdoor activity for the time being, especially during the early morning and evening
Make sure that your child wears a face mask when outside, preferably N95 or 99
Use air purifiers at home 
Go green and use indoor plants that can remove indoor toxins
Boost your child's immunity
Lastly, keep a track of air quality index in your locality

Pollution - How It Can Affect Your Child's Lungs?

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

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

Dust mites belong to a family of ticks and spiders, and cannot be seen through bare eyes. They thrive in places which are warm and humid.

Dust mite allergies are the most common type of allergy found in many people. Patients suffering from house dust mite allergies may also face sneezing and a runny nose. The symptoms are just the same as asthma.

The best way to get rid of dust mite allergies is to make the house as much dust-free as possible.

In case a person is attacked by any of these dust mites, doctors may also suggest some medicines to suppress the symptoms and ease the condition.

Symptoms of House Dust Mite Allergy:

House dust mite allergy causing inflammation in the nasal passages may show signs like:

Watery eyes

Runny nose

Redness in the eyes

Sneezing

Congestion

Facial itching

Redness and skin spores opening

Face infection

If the allergy is contributing to Asthma, the following signs are observed:

Difficulty in breathing

Heaviness in the chest

Chest pain

Wheezing sound with cough and cold

Shortness of breath

The signs of a house dust mite allergy can be severe in some cases. However, allergies are not life-threatening, but prolonged symptoms may affect health. A mild allergy-like runny nose or sneezing are common. However, if a person is suffering from symptoms for a more extended period of time, he/she should consult an ENT specialist for the same.

Diagnose of House Dust Mite Allergy:

To diagnose this type of allergy, doctors check the patient physically and if the patient has problems persistently round the year, then he/she may be advised to take an allergy test. Allergy tests consist of skin prick tests and blood tests.

Skin Prick Test: Skin Prick Test, or SPT, is not a conclusive test for every patient. The doctors determine the result by comparing the conditions. In SPT, the doctors put a small drop of possible allergen on the skin and prick the skin with a needle to see the reaction. If a person is allergic to the allergen, he/she may observe a wheal, itching, or redness in the area. However, the doctors determine the results based upon the time and place of the symptoms he/she is complaining of.
Blood Test: Blood test is an excellent tool when the patient cannot give successful skin test. Blood tests are referred by the doctors in the cases when the patient is taking some medicines that interfere with the skin test or to the kids who cannot tolerate skin test. The blood sample is obtained by the doctors, and an allergen is added to the sample. The lab doctors observe whether there is any reaction in the sample due to the allergen.
Treatment:

The best way to fight house dust mite allergy is to avoid allergens. The doctors suggest measures to keep the surrounding dust free and use the covers or sprays that kill dust mites. The dust mites thrive in warm and humid areas. Hence, one should keep the surrounding cool and open to stop their growth. Many patients do not get complete relief from allergies with medicine, and in such cases, doctors provide special therapies and sprays to keep the dust mites away.

Conclusion:

There are many treatment options available depending upon the severity and condition of the allergy. However, it is best to consult a doctor before opting for any treatment or medicines.
