Types Of Adverse Reactions To Foods
Adverse food reactions can be grouped as follows:
Whilst some symptoms may be similar, food allergies are different to food intolerances , which include:
- Metabolic conditions such as lactose intolerance and carbohydrate malabsorption .
- Pharmacologic reactions to food components such as caffeine, monosodium glutamate and other naturally occurring food chemicals .
- Toxic reactions such as food poisoning and scombroid fish toxin.
- Adverse reactions to artificial preservatives such as sulphites and benzoates have been shown to cause symptoms. These preservatives have also been reported as triggers for asthma and anaphylaxis.
Natural substances in foods can cause food intolerances
Foods are composed of proteins, carbohydrates, fats, various nutrients and several natural chemicals. These following naturally occurring substances often add flavour and smell to food but they can trigger symptoms in some people.
Medical Conditions Responsible For Stomach Ache
Some types of stomach pain need not be linked to what you eat. They can be caused by conditions that are triggered by when you eat. These include:
How To Get Tested
A food allergy will usually cause some sort of reaction every time the trigger food is eaten. Symptoms can vary from person to person, and you may not always experience the same symptoms during every reaction. Allergic reactions to food can affect the skin, respiratory tract, gastrointestinal tract and cardiovascular system. It is impossible to predict how severe the next reaction might be, and all patients with food allergies should be carefully counseled about the risk of anaphylaxis, a potentially fatal reaction that is treated with epinephrine .
While food allergies may develop at any age, most appear in early childhood. If you suspect a food allergy, see an allergist, who will take your family and medical history, decide which tests to perform and use this information to determine if a food allergy exists.
To make a diagnosis, allergists ask detailed questions about your medical history and your symptoms. Be prepared to answer questions about:
- What and how much you ate
- How long it took for symptoms to develop
- What symptoms you experienced and how long they lasted.
After taking your history, your allergist may order skin tests and/or blood tests, which indicate whether food-specific immunoglobulin E antibodies are present in your body:
Your allergist will use the results of these tests in making a diagnosis. A positive result does not necessarily indicate that there is an allergy, though a negative result is useful in ruling one out.

Food Allergy Immune System
Food allergies can cause severe or even life-threatening allergic reactions, known as anaphylaxis. Most food allergies are IgE-mediated. This means if you have a peanut allergy, your immune system identifies the proteins in peanuts as foreign invaders or allergens. The immune system then produces antibodies called Immunoglobulin E , in an attempt to defend the body. These antibodies interact with cells triggering the release of pro-inflammatory chemicals, called histamines, which cause an allergic reaction.
Could My Symptoms Be Something Else
If you regularly have diarrhoea, bloating, tummy pain or skin rashes but you’re not certain of the cause, see a GP.
A GP may be able to diagnose the cause from your symptoms and medical history. If necessary, they’ll order tests, such as blood tests.
You can also do some research yourself. It may help to find out about other conditions that cause similar symptoms. For example, find out about:
The bowel is a sensitive organ and it’s common to have bowel symptoms when you have been ill or feel run down or stressed.

- Drink plenty of water and eat fiber-rich foods, such as fruits and vegetables, to keep food moving through your digestive system.
- Avoid foods that have passed their expiration date or or werenât stored properly.
- If you have a food allergy or intolerance, avoid eating foods that make you sick. If you have a food allergy, always carry two epinephrine auto-injectors, and know when you should use them.

Definition Of Food Sensitivity
While a food allergy is an immune system response to a food, food intolerance is a problem with digesting foods.
People with food intolerances can have gastrointestinal symptoms like bloating, gas, abdominal pain, and diarrhea after eating certain foods.
Unlike a food allergy, food intolerance does not cause anaphylactic reactions.
Identifying a food intolerance requires careful observation of cause and effect. Some people are intolerant to food additives, like flavorings, dyes, and preservatives.

Food Allergies: Biggest Myths And Misconceptions Debunked
While it remains unknown exactly why food allergies are on the rise, several theories have tried to explain it:
1. The hygiene hypothesis.
Simply put, were way too clean, and we keep our children away from normal germs that help strengthen their immune system.
2. Delaying the introduction of high allergen foods.
The delay might not prepare the developing immune system for new foods.
3. Changes in the food supply.
The way food is grown might impact the potential for an allergic response.
Regardless of the cause, kids and parents needs to know what to do when a food allergy turns up. And importantly, know the differences between food sensitivities, food intolerance, and a true food allergy.
Test your knowledge with our food allergy quiz, and learn to recognize potential food-related issues impacting your familys health.

Onset: How Long Does It Take For Your Symptoms To Emerge
Food allergies are characterized by rapid onset, usually emerging in less than 30 minutes after consuming the food in children and within 2 hours in adults. Symptoms of a food stomach allergy tend to resolve within 48 hours. While the food allergy symptoms are typically immediately after ingestion, they are not as severe and sometimes can take a few hours to develop. In some cases, once symptoms are present, it may take hours and sometimes even days to disappear.

Severe Food Allergy In Children
Allergic reactions, including anaphylaxis, are common, although deaths from anaphylaxis are rare. Most schools and childcare services across Australia are required to have an anaphylaxis management policy in place.Banning particular foods is not recommended as it can create a sense of complacency and is difficult to monitor and enforce. A better approach is to educate staff, students and the community about the risks associated with anaphylaxis and put strategies in place to minimise exposure to known allergens.

Food Allergy Rash And Anaphylaxis
The most severe type of allergic reaction is anaphylaxis, which is a life-threatening condition. This is not a complication of a food rash itself, but rather a complication of the overall allergic reaction. Hives and anaphylactic reactions often occur together, but you can have hives without having anaphylaxis.
On top of the food allergy symptoms listed above, anaphylaxis may cause:
- breathing difficulties
- severe swelling in the mouth, face, neck, and throat
- tightness in the throat
- tingling lips, hands, and feet
If your doctor recommends epinephrine shots for severe food allergies, its important to keep them on hand at all times. Even breathing in a food allergen can cause severe issues. Also, the severity of a reaction may vary just because one reaction was mild, doesnt mean the next will also be mild.
Anaphylaxis is a medical emergency. Call 911 or your local emergency services and take your epinephrine shot as soon as you experience symptoms. Antihistamines cant treat anaphylaxis because the symptoms are too severe at this stage.
Food Allergy Is Increasing
Allergies in general are on the increase worldwide and food allergies have also become more common, particularly peanut allergy in preschool children. About 60 per cent of allergies appear during the first year of life. Cows milk allergy is one of the most common in early childhood. Most children grow out of it before they start school.

Tips To Avoid Bloating
Its not just what you eat that can cause bloating. How you eat and how much you eat also plays a role. To keep your belly from feeling swollen, Czerwony offers this advice:
- Chew more. Smaller bits of food are easier to digest than large chunks, making it less likely that dinner will hang around too long in your gut.
- Stay hydrated. Drinking more fluids helps keep things moving along in your GI tract. Think of it like adding water to a Slip N Slide®.
- Dont go back for seconds. Eating too much overloads your digestive system. Just think of how you sometimes feel after Thanksgiving dinner, advises Czerwony.
- Be mindful of dietary changes. Your body adjusts to what you eat to a certain extent. But if suddenly start eating different foods, your digestive system may struggle to handle the change.
If youve already made some choices that left you bloated, dont worry: The feeling will pass. It might be a good idea to go for a walk, though, recommends Czerwony. If you start moving, that food will start moving, too.
You also might want to consider changing your shopping list to include some of these foods that can help reduce bloating.

Whats The Difference Between Food Intolerance And Food Allergies
Food intolerance, or food sensitivity, is not the same thing as having a food allergy.
A food intolerance:
- Occurs when your digestive system cant break down certain foods.
- Causes symptoms like an upset stomach that arent life-threatening.
- Brings on symptoms within a few hours after eating as the food makes its way through the digestive tract.
- May not cause symptoms if you eat just a small amount of a food.
A food allergy:
- Brings on symptoms within minutes of consuming even a small amount of an allergy-inducing food.
- May cause a severe, life-threatening reaction called anaphylaxis. Without an epinephrine treatment, this reaction can be fatal.
How Can You Prevent Food Intolerance
You can take some precautionary steps to prevent the undesirable symptoms of food intolerance.
- Over time, you can learn which foods cause indigestion and limit their intake or only consume them in small amounts.
- Read food labels to check for problem or trigger ingredients. Labels of processed foods usually list the ingredients that people are most commonly allergic or intolerant to.
- You may inform the waiter or chef about your intolerance if you are dining out.
Some intolerances are manageable. For example, you can drink lactose-free milk instead of avoiding milk altogether if you are lactose intolerant. For symptoms like heartburn or stomachache, you can take antacid medication.

Unproven Ways To Diagnose Food Allergies
Some techniques can’t effectively identify food allergies. These include:
Cytotoxicity testing. A food allergen is added to your blood sample. A technician then checks the sample under the microscope to see if white cells in the blood “die.”
Sublingual or subcutaneous provocative challenge. It’s similar to a skin test, but the sample of food allergen goes under your tongue or gets injected under your skin.
Immune complex assay. This blood test looks for groups of certain antibodies bound to the food allergen. But these clusters normally form as part of food digestion, and everyone, if tested with a sensitive enough measurement, has them.
IgG subclass assay. This blood test looks specifically for certain kinds of IgG antibodies, but they’re part of a normal immune response.
Can Lactose Intolerance Cause Gastritis
Lactose intolerance refers to the troubles in your digestive system processing dairy products milk, egg, cheese, etc. If you have lactose intolerance, you may suffer from gastritis, inflammation in your stomach lining. Usually, you face lactose intolerance when your small intestine fails to produce enough lactase. Its a type of enzyme that assists in food absorption. Lactose intolerance causes intestinal infections, intestinal disease, and other gastrointestinal tract conditions, including gastritis.

Celiac Disease: Allergy Or Intolerance
Celiac disease can cause similar symptoms, but its neither a food allergy nor a food intolerance.
Its actually an autoimmune disorder triggered by gluten, a protein found in grains like wheat, barley and rye, Jaeger explains. For people who have celiac disease, eating even the smallest amount of gluten can actually cause damage to the small bowel.
But and heres where it can get confusing you can have a gluten intolerance without having celiac disease or a wheat allergy. In this case, eating gluten may make you feel bloated, gassy or tired, but it wont cause an allergic reaction or damage to your gastrointestinal tract.
What Is Food Intolerance
When you have a food intolerance, it means your digestive system has a hard time digesting a food. Another word for food intolerance is food sensitivity.
Food intolerance means your gut is sensitive to certain foods and cant tolerate them. When you eat these foods, you may experience uncomfortable symptoms like gas, diarrhea and abdominal pain.
