There are a lot of different food allergens out there, and it can be tough to keep track of them all. Here’s a quick rundown of the most common allergens and how many there are.

A food allergy is when your body has a specific and adverse reaction to a particular food or food component. Allergic reactions to food can range from mild to severe, and in some cases, can be life-threatening.
The proteins that we eat are the primary allergens in food. Proteins can either be naturally occurring or added during processing. In either case, the proteins can trigger an immune response in people who are allergic to them.
There are eight major food allergens that account for the majority of reactions: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans. These eight allergens are responsible for the vast majority of serious allergic reactions to foods.
The eight most common food allergens
There are eight major food allergens that are responsible for the majority of food allergy reactions in the United States:
These eight allergens are responsible for the majority of food allergies, but there are many other potential allergens.
Allergens and the immune system
There are many different kinds of food allergens, but the most common are proteins. When these proteins enter the body, they trigger an immune system response. The immune system produces antibodies to try to counteract the allergen proteins.
In some people, this response is so severe that it can lead to anaphylaxis, a potentially life-threatening condition. Other people may have less severe reactions, such as hives or stomach cramps.
The best way to deal with a food allergy is to avoid the offending food entirely. However, this can be difficult, because food allergens are often found in unexpected places. For example, milk proteins can be found in some brands of bread and chicken eggs are sometimes used as a binding agent in processed meats.
If you have a food allergy, it’s important to read food labels carefully and always ask about ingredients when you’re eating out.
How allergies are diagnosed
There are two types of food allergy tests: skin prick tests and blood tests.
A skin prick test is when a small amount of a liquid that contains the allergen is placed on the skin. A needle is then used to prick the skin’s surface. If you’re allergic to the allergen, you’ll develop a red, raised itchy bump called a wheal within 15 minutes.
A blood test can measure your immune system’s response to an allergen by looking for antibodies in your blood. Antibodies are proteins that are produced by the immune system to help fight off infections and other foreign substances.
If you have a positive skin prick test or blood test, your allergist will likely do additional testing to be sure. This might include a food challenge or oral food challenge. During a food challenge, you’ll eat increasing amounts of the suspected food under medical supervision to see if you have a reaction.
An oral food challenge is similar to a skin prick test, but instead of being placed on your skin, the allergen is swallowed.
Managing food allergies
There are eight major food allergens in the United States, and they must be listed on packaged foods by law. These eight allergens are milk, eggs, peanuts, tree nuts, soy, wheat, fish, and crustacean shellfish. If a packaged food contains any of these allergens, it must say so in plain language on the label.
The role of diet in managing food allergies
The role of diet in managing food allergies is becoming increasingly recognized. A growing body of evidence suggests that Elimination Diets (EDs), which remove common allergens from the diet, can be an effective treatment for food allergies. However, there is still much debate surrounding the exact number of allergens that should be eliminated, and which allergens are the most problematic.
The eight most common food allergens are milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish. These eight allergens account for 90% of all food allergies. However, there is evidence to suggest that other less common allergens may also cause problems for some people. Some experts believe that as many as 150 different foods may trigger allergic reactions in susceptible individuals.
Elimination Diets are often used to identify hidden food allergies. These diets typically involve removing all potential allergens from the diet for a period of time (usually 2-4 weeks), and then slowly reintroducing them one at a time to see if any adverse reactions occur. Although Elimination Diets can be time-consuming and difficult to stick to, they may be the only way to determine which foods are causing problems.
The role of medication in managing food allergies
It’s estimated that about 15 million Americans have food allergies, and for many of them, the only way to manage their condition is to avoid the foods that trigger their reactions. But what if there were a way to take a pill that would allow you to eat the foods you’re allergic to without having a reaction?
That’s the goal of a new type of medication called “oral immunotherapy,” or OIT. OIT involves gradually exposing patients to escalating doses of the food allergens they’re trying to desensitize themselves to. The idea is that over time, the patients will build up a tolerance to the allergens and will no longer have reactions when they eat them.
OIT is still in the early stages of development, and it’s not yet clear how well it works or how long the effects last. But for some people with severe food allergies, it may be worth considering.
The role of immunotherapy in managing food allergies
There are eight major food allergens that are responsible for the vast majority of food allergies: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans. These eight foods account for 90 percent of all food allergies.
Allergies to these foods can cause a range of symptoms from mild (rashes, hives, itching, swelling) to severe (difficulty breathing, hypotension, anaphylaxis). For some people with food allergies, even small amounts of the offending food can trigger a potentially life-threatening reaction.
There is no cure for food allergies, but strict avoidance of the offending food is the only way to prevent an allergic reaction. For some people with milder allergies, this may be possible with careful labeling and avoidance of cross-contamination. However, for people with severe allergies, this can be a very difficult and restrictive way to live.
Immunotherapy is a potential treatment for food allergies that is currently under investigation. Immunotherapy involves exposing the person to increasing amounts of the offending allergen in order to build up tolerance. This treatment is still in the early stages of research and is not yet approved for use in humans.
Living with food allergies
Food allergies are a growing concern in the United States. According to the Centers for Disease Control and Prevention (CDC), the number of Americans with food allergies has increased since the late 1990s. In fact, it is estimated that more than 15 million people in the U.S. have food allergies, including 6 million children.
A food allergy is an immune reaction to a food protein. When someone with a food allergy eats that food, their body reacts as if it is under attack. The symptoms of a food allergy can range from mild (rash, hives, itching, swelling) to severe (trouble breathing, wheezing, dizziness, confusion, nausea, vomiting, fainting). In some cases, a food allergy can be life-threatening.
There are eight major allergens that account for 90% of all food allergic reactions in the United States: milk, eggs, fish, crustacean shellfish, tree nuts peanuts , wheat and soybeans. These eight allergens are required by law to be listed on packaged foods sold in the U.S., regardless of whether they are present in the final product or not.
If you have a food allergy , it is important to educate yourself about the foods you need to avoid and how to stay safe . You should also have an emergency plan in place in case of accidental exposure to an allergen .
The FDA lists nine major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and corn. These account for about 90 percent of all food allergies.There are also many other potential allergens that are not well studied or understood. These include ingredients like spices, certain fruits and vegetables, artificial flavors and more. If you have a food allergy, it is important to know what ingredients to avoid.
