What is food Allergies?
Food allergies are when the body’s immune system reacts abnormally to certain foods. Although allergic reactions are often mild, they can be very serious. Symptoms of allergies food can affect different areas of the body at the same time. Some common symptoms include Sensation of itching inside the mouth, throat, or ears.
Every time people eat, they come in contact with substances that can cause allergic reactions. Although people may show these reactions due to many foods, only a handful of foods cause most allergies.
Foods contain protein allergens. For most people, these proteins do not cause allergic reactions. Although many foods can cause allergic reactions, only nine common foods make up a reliable source of 90% of allergies in the United States. These are:
Almonds or pecans
Babies are usually allergic to peanuts, milk, soybeans, nuts, eggs, and wheat, but many children stop being allergic to foods like milk, eggs, wheat, and soy early in childhood.
Adults with food allergies usually respond to tree nuts, peanuts, fish, and shellfish. When a person thinks they have a food allergy but are not sure what food they are responding to, an allergist may recommend a food allergy test. This can be done through the skin or blood tests.
This article looks at a variety of common food allergies, the symptoms of each allergy, and what people can do to avoid a reaction. In severe cases, a severe and sometimes fatal allergic reaction called anaphylaxis can occur due to food allergies. A person with this acute reaction should seek immediate medical attention. People should keep epinephrine in hand whenever possible and use it to treat anaphylaxis immediately.
Like many food allergies, an egg allergy the main proteins that cause an allergic reaction to common eggs in childhood are ovomucoid, ovalbumin, and ovotransferrin.
Some people may eat baked or cooked eggs without an allergic reaction, but others do not. Some people may be allergic to eggs or to birds that have dropped their feathers. This is called the trusted source of the bird-egg syndrome.
Symptoms of egg allergy
Symptoms of egg allergy may include nausea, abdominal pain, and indigestion, shortness of breath, or cough. The best way to avoid allergic reactions to eggs is to avoid eggs or foods that contain them. Egg allergy is the most common food allergy. Egg allergy is not the same as egg intolerance.

Adults are more likely to be allergic to fish and shellfish than children. Some people will only respond to certain types of fish and others may respond to all fish. The degree of reaction may vary depending on the type of fish people eat.
Most people who are allergic to fish will react to a protein allergen called parvalbumin. Cooking does not destroy these proteins, which means that people can have a reaction to both cooked and raw fish.
Symptoms of fish allergy
Symptoms of allergies to fish may include skin rashes. People may also get symptoms of cold, runny nose, sneezing or asthma. For people who are allergic to fish, it is important to avoid fish and fish products.
Cow’s milk allergy is one of the most common food allergies in childhood. A person may react by eating even a small amount of milk or dairy foods.
Some nursing babies may experience colic or eczema if the mother eats cow’s milk or dairy foods.
Many babies will overcome milk allergies. A study from the American College of Allergy, Asthma, and Immunology (ACAAI) found that 53% of infants under one year of age are allergic to milk, but only 15% of adolescents.
Symptoms of milk allergy
Symptoms of milk allergy include nausea, diarrhea, and nausea. People may be allergic to two different milk proteins, casein, and mother. Many foods that are not tasty milk or dairy foods may contain these proteins. People who are allergic to milk should be careful not to eat it or take any milk or dairy products
A milk allergy is not like lactose intolerance. People who have lactose intolerance are not allergic to milk. Instead, it means they do not have enough of the enzyme lactase, which they need to break down lactose.

Tree nuts Allergy
Allergies to tree nuts are usually lifelong. Allergies to shellfish and peanuts, as well as allergies to tree nuts, are among the most frequently food-induced causes of anaphylaxis. Almonds are most likely to cause an allergic reaction:
Sometimes, people who are allergic to one type of nut may react to the other.
Tree nuts are allergy symptoms
People with allergies to tree nuts may react differently in different ways. Symptoms include hives, nausea, low blood pressure, or difficulty swallowing. Some people may experience itching in the mouth, throat, skin, eyes, or other parts of the body. People with allergies to nuts should avoid eating them or any such food.

Peanuts are one of the most common causes of food allergies. People who are allergic to peanuts usually have allergies throughout their lives. Nevertheless, recent research shows that about 20% of allergic people can overcome allergies. An allergic reaction to a peanut can be intense, and even the signs of a peanut can be enough to cause a reaction in sensitive individuals.
A minority of people with peanut allergies may also react to other legumes trusted sources such as green peas.
Although peanuts are not almonds, people with allergies to peanuts sometimes have allergies to certain almonds.
Cooking some allergenic foods may remove the protein that causes the reaction, but studies show that this is probably not the case with roasted, boiled, reliable sources or fried peanuts.
Experts believe that peanut oil is safe for people with peanut allergies because the allergenic protein is removed during the production process. However, cold pressed or unrefined peanut oil may contain small amounts of peanut allergens, which can cause reactions in sensitive individuals.
Peanut allergy symptoms
People who are allergic to peanuts will experience many of the same symptoms as people who are allergic to other foods. These symptoms include stomach problems, weak pulse, bloating, bloating, dizziness and confusion.
People with allergies should be careful before eating peanuts in any form.
Shellfish allergies are different from fish allergies. Many types of shellfish can cause reactions in people with allergies, including:
People who are allergic to one type of shellfish often find that they react to other types of shellfish.
Symptoms of shellfish allergy:
People with shellfish allergies may have nausea, sores, and most other food allergies.
A shellfish allergy can often cause severe reactions and some people may even react to steams from cooking shellfish. Like other food allergies, people should be exposed to shellfish if they have these allergies.

Soybean allergy is a common childhood allergy. Most people who are allergic to soybeans are under 3 years of age, but sometimes adults are allergic to soybeans.
Symptoms of soybean allergy:
People who are allergic to soybeans may experience rashes, nausea, diarrhea, and stomach cramps. Rarely soybeans can cause anaphylaxis.
Avoiding soybeans is the key to avoiding reactions. Some people may refine foods containing soy lecithin in soybean oil or substances produced during soybean processing. People with allergies should consult a doctor to see if it is safe for them.
Substances that cause allergic reactions are called allergens.
Other common allergens include:
Grass and tree pollen – one of them is known as allergic hay fever (allergic rhinitis). Dust
Small flakes of animal skin, skin, or hair
Food – especially nuts, fruits, shellfish, eggs, and cow’s milk
Insect bites and stings
Medications – including ibuprofen, aspirin, and certain antibiotics
Latex – Used to make some gloves and condoms
Mold – These can release small particles into the air that can breathe
Household chemicals – including detergents and hair dyes
Most of these allergens are usually harmless to people who are allergic to them
Symptoms of Common allergies reaction
Allergic reactions usually occur within minutes of exposure to the allergen.
They can cause:
A runny or stuffy nose
Red, itchy, watery eyes
Wounds and coughs
A red, itchy rash
Deterioration of asthma or eczema symptoms
Most allergic reactions are mild but can sometimes lead to an acute reaction called anaphylaxis or anaphylactic shock.
This is a medical emergency and requires emergency treatment.
