What Are the Major Food Allergens You Need to Know?

While ongoing research explores new treatments for food allergies, currently, there is no definitive cure. Identifying allergenic foods through medical diagnosis and strictly avoiding them remains crucial for preventing severe health consequences. This article will delve into the major food allergens you need to be aware of to protect yourself and your loved ones.

Understanding Major Food Allergens

Although a wide range of foods can trigger allergic reactions, the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) originally identified eight foods as major food allergens. These were milk, eggs, fish, Crustacean shellfish, tree nuts, peanuts, wheat, and soybeans. These allergens are responsible for the vast majority of serious food allergy reactions.

The landscape of food allergens evolved with the signing of the Food Allergy Safety, Treatment, Education, and Research (FASTER) Act into law on April 23, 2021. This act declared sesame as the 9th major food allergen recognized in the United States. This change took effect on January 1, 2023, mandating that sesame be clearly listed on food labels. However, during the transition, some products may not yet reflect this change.

Here’s a breakdown of the nine major food allergens:

1. Milk: All forms of milk, including cow’s milk, goat’s milk, and sheep’s milk, can trigger allergic reactions. This includes products like cheese, yogurt, and butter.

2. Eggs: Typically refers to chicken eggs, but eggs from other birds (such as ducks or quail) can also cause allergic reactions.

3. Fish: Specific types of fish, like bass, flounder, and cod, are common allergens. However, allergies can occur to any fish species.

4. Crustacean Shellfish: This includes crab, lobster, and shrimp.

5. Tree Nuts: Examples include almonds, walnuts, pecans, cashews, and pistachios. It’s important to note that an allergy to one type of tree nut doesn’t necessarily mean an allergy to all tree nuts.

6. Peanuts: Despite the name, peanuts are legumes, not tree nuts. Peanut allergy is one of the most common and severe food allergies.

7. Wheat: Found in many baked goods, cereals, and pasta. People with wheat allergies react to proteins in wheat, not gluten specifically (which is relevant for celiac disease).

8. Soybeans: Soy products are prevalent in many processed foods, including soy sauce, tofu, and soy milk.

9. Sesame: Sesame seeds and sesame oil are increasingly common ingredients in various cuisines and packaged foods.

Carefully reading food labels and ingredient lists is essential to identifying potential allergens and protecting yourself from allergic reactions. The alt text emphasizes the action of reading labels and the importance of ingredient awareness.

Understanding Allergen Labeling Regulations

The FDA diligently enforces FALCPA regulations for labeling foods under its jurisdiction. These regulations mandate that food labels clearly state the food source names of any ingredients that are identified as one of the nine major food allergens, or if they contain protein derived from a major food allergen. This is crucial, as it directly helps consumers with allergies identify and avoid foods containing ingredients that could cause them harm.

How Major Food Allergens Must Be Listed on Labels

To comply with FALCPA regulations, food manufacturers must clearly identify the food source names of all major food allergens used in their products. This can be achieved in one of two ways:

1. Parenthetical Declaration: The allergen’s food source name can be listed in parentheses directly following the ingredient in the ingredient list.
   • Examples: “lecithin (soy)”, “flour (wheat)”, “whey (milk)”.
2. “Contains” Statement: Alternatively, the allergen’s food source name can be declared immediately after or next to the ingredient list in a “contains” statement.
   • Example: “Contains Wheat, Milk, and Soy”.

Recognizing the Symptoms of Food Allergies

Being able to recognize the symptoms of food allergies is just as important as knowing what the major allergens are. Symptoms can vary from mild to severe and can appear within minutes to a few hours after consuming the allergenic food.

Common symptoms of food allergies can include:

• Hives
• Flushed skin or rash
• Tingling or itchy sensation in the mouth
• Swelling of the face, tongue, or lips
• Vomiting and/or diarrhea
• Abdominal cramps
• Coughing or wheezing
• Dizziness and/or lightheadedness
• Swelling of the throat and vocal cords
• Difficulty breathing
• Loss of consciousness

The Life-Threatening Potential of Food Allergies: Anaphylaxis

While many food allergy symptoms are mild, it’s critical to understand that some reactions can escalate into a severe, life-threatening allergic reaction known as anaphylaxis.

Anaphylaxis can manifest as:

• Constricted airways in the lungs
• A severe drop in blood pressure leading to shock (anaphylactic shock)
• Suffocation due to swelling of the throat and larynx

If you suspect you are experiencing anaphylaxis:

• Immediately stop eating the suspected food.
• Assess the need for emergency treatment, such as an epinephrine injection.
• Seek immediate medical attention.

It’s crucial to remember that even seemingly mild allergic reactions have the potential to progress to anaphylaxis. Individuals with known food allergies should always be vigilant, monitor their symptoms closely, and seek medical care if any concerning symptoms arise.

What To Do If You Experience Symptoms

The development of symptoms after eating particular foods could point to a food allergy. You should stop consuming the food(s) that caused these symptoms. Contact a healthcare provider for assessment and testing to confirm the allergy.

If you or a loved one suspects a food allergy, follow these guidelines to minimize the risk of getting sick:

1. Read Food Labels Every Time: Always check the ingredient list, even for familiar products, as formulations can change.
2. Strictly Avoid Allergenic Foods: The most effective way to prevent a reaction is to avoid the offending food and any products that may contain it.
3. Learn to Recognize Early Symptoms: Early recognition can allow for prompt treatment and prevent a reaction from escalating.
4. Have a Plan of Action: Know what to do in case of accidental ingestion, including having readily available epinephrine and knowing how to administer it.

Reporting Adverse Reactions and Labeling Concerns to the FDA

If you or a family member experiences an allergic reaction after consuming an FDA-regulated food product, particularly if the labeling is unclear or you suspect a hidden allergen, consult with your healthcare provider. Save the food packaging, as it may contain vital information. You may also wish to contact the manufacturer directly.

You can also report complaints or adverse events (illness or severe allergic reactions) to the FDA through their Industry and Consumer Assistance portal.

Include as much detail as possible in your report, such as:

• Details about the person reporting the incident and the affected individual (names, addresses, phone numbers).
• The name and address of the place where the product was purchased.
• A thorough description of the reaction:
  • The date the reaction occurred.
  • All symptoms experienced.
  • The time elapsed between consumption and the onset of symptoms.
  • Any medications used to alleviate symptoms.
  • Whether the reaction required medical intervention, and if so, details about the care received (including contact information for the doctor or hospital).
• A comprehensive description of the product:
  • The date of purchase.
  • Any codes or identifying marks on the label or container (lot number, expiration date, UPC code).
  • Photos of the product, label, ingredient statement, and lot code.

Consumer reports of adverse events are invaluable in helping the FDA identify potentially problematic products and strengthen consumer protection. By staying informed, vigilant, and proactive, we can all contribute to a safer food environment for individuals with allergies.
