A food allergy is an immune system reaction that happens soon after eating a particular food; in some people, a food allergy can result in severe symptoms or even a life-threatening reaction called anaphylaxis. Even a small amount of the allergy-causing food can cause signs and symptoms like digestive issues, hives, or swollen airways.

While there is currently no treatment for food allergies, it is estimated that 6 to 8% of children under the age of 3 and up to 3% of adults suffer from them.

Food intolerance, while annoying, is a less serious condition that does not involve the immune system, and it is simple to confuse it with a much more frequent reaction known as a food allergy.

Causes-If you have a food allergy, your immune system misinterprets a particular food or food component as being harmful, causing cells to release immunoglobulin E (IgE) antibodies to neutralize the offending food or food component (the allergen).

These substances are to blame for a variety of allergy signs and symptoms, including runny nose, itchy eyes, dry throat, rashes and hives, nausea, diarrhea, labored breathing, and even anaphylactic shock.

The majority of food allergies are triggered by certain proteins in:

Shellfish, including crab, lobster, and shrimp

· Peanuts

Tree nuts, including pecans and walnuts

· Fish

· Eggs

In children, food allergies are commonly triggered by proteins in:

· Eggs

· Milk

· Peanuts

· Tree nuts

· Wheat

Food intolerance and other reactions

Depending on the type of food intolerance you have, you may be able to consume small amounts of problematic foods without experiencing any negative effects, whereas if you have a true food allergy, even a small amount of food may result in an allergic reaction.

People may mistake a food intolerance for a food allergy due to the similarities between the two, including the signs and symptoms of nausea, vomiting, cramping, and diarrhea.

Because some people are sensitive to a substance or ingredient used in the preparation of the food rather than the food itself, diagnosing food intolerance can be challenging.

the following common diseases can manifest symptoms similar to those of a food allergy:

Absence of an enzyme needed to fully digest a food.Lack of some digestive enzymes, such as lactase, which is necessary to break down lactose, the primary sugar in milk products, can result in bloating, cramping, diarrhea, and excess gas. Lactose intolerance is another condition that can occur.

Food poisoning.Bacteria in spoiled tuna and other fish can also produce a toxin that causes reactions that are harmful, which is why food poisoning can occasionally mimic an allergic reaction.

Sensitivity to food additives.Sulfites, which are used to preserve wine, canned goods, and dried fruit, can cause asthma attacks in people who are sensitive to them. Other food additives that could cause severe reactions include monosodium glutamate (MSG), artificial sweeteners, and food colorings. Some people experience digestive reactions and other symptoms after consuming certain food additives.

Histamine toxicity.Instead of an allergic reaction, this is referred to as histamine toxicity or scombroid poisoning and can occur with certain fish, such as tuna or mackerel, that are not properly refrigerated and that contain high levels of bacteria.

Celiac disease.The chronic digestive disorder celiac disease is brought on by eating gluten, a protein present in bread, pasta, cookies, and many other foods containing wheat, barley, or rye, but it isn’t a true food allergy. Like a food allergy, it does involve an immune system response, but it’s a particular immune system reaction that’s more complex than a simple food allergy.

If you have celiac disease and consume gluten-containing foods, your small intestine will become damaged due to an immune response, making it difficult for you to absorb certain nutrients.

Food allergy symptoms typically appear one to two hours after consuming the offending food, but they can also appear minutes, hours, or even minutes after eating the offending food for some people, making them uncomfortable but not life-threatening for others.

Among the most typical warning signs and symptoms of a food allergy are:

Itchiness or tingling in the mouth

· Hives, itching or eczema

Body swelling in other areas, such as the throat, tongue, lips, or face.

Wheezing, stuffy nose, or breathing issues

Stomach aches, diarrhea, motion sickness, or nausea

· Dizziness, lightheadedness or fainting


Anaphylaxis, a severe allergic reaction that can be brought on by a food allergy, can occur in some people and result in life-threatening symptoms such as:

Airways narrowing and becoming more constricted

A lump in your throat or a swollen throat that makes breathing difficult

Shock accompanied by a sharp decrease in blood pressure

· Rapid pulse

Feeling dizzy, lightheaded, or unconscious

Anaphylaxis must be treated right away because if it is not, it can put a person in a coma or even kill them.

Exercise-induced food allergy

Eating some foods may make you feel itchy and dizzy shortly after you begin exercising, and in severe cases, an exercise-induced food allergy can result in reactions like hives or anaphylaxis.

Avoiding certain foods and waiting a couple of hours after eating before working out may help avoid this issue.

Pollen-food allergy syndrome

Some people with pollen-food allergy syndrome, also known as oral allergy syndrome, may experience throat swelling or even anaphylaxis, while others may experience mouth tingling or itching due to an allergic reaction to fresh fruits, vegetables, and some nuts and spices.

As an illustration of cross-reactivity, if you have an allergy to ragweed, you may also have an allergic reaction to melons, and if you have an allergic reaction to birch pollen, you may also have an allergic reaction to apples.

The majority of fruits and vegetables that are cooked typically don’t result in oral allergy symptoms that are cross-reactive, so cooking them can help you avoid this reaction.

Fruits and vegetables and pollens frequently react cross-reactively:

Risk elements—Risk elements for food allergies include:

Family history.If you have a history of hay fever, asthma, eczema, or other allergies in your family, you are more likely to develop food allergies.

A past food allergy.A food allergy may go away in children, but it sometimes comes back as adults.

Other allergies.You may be more likely to develop an allergy to another food if you already have one, and you may also be more likely to develop an allergy to food if you already have hay fever or eczema.

Age.Fortunately, children typically outgrow allergies to milk, soy, wheat, and eggs. Severe allergies and allergies to nuts and shellfish are more likely to be lifelong. Food allergies are most common in children, especially toddlers and infants. As you get older, your digestive system develops and your body is less likely to absorb food or food components that trigger allergies.

Asthma.Food allergy and asthma frequently co-occur, and when they do, the symptoms of both conditions are more likely to be severe.

You could be more susceptible to experiencing an anaphylactic reaction if:

Being asthmatic in the past

Being in your teens or younger

Delaying the administration of epinephrine to treat the signs and symptoms of a food allergy.

Absence of skin symptoms such as hives
