Food allergies are more common than many realize, and while most are familiar with peanuts, eggs, dairy, and shellfish, there are lesser-known allergens that can also cause reactions. These less common food allergies can still lead to significant discomfort, making it important to recognize the signs and protect yourself. Let’s explore some of these unexpected triggers.
1. Sesame seed allergy
Sesame is one of the most recent allergens to be added to the “big eight” food allergens list in the U.S. In some countries, it’s already well-known as an allergen.
- • Where sesame is found: Baked goods, snacks, tahini, and hummus
- • Symptoms: Rashes, swelling, difficulty breathing
The key here is vigilance when reading ingredient labels and asking about food preparation when dining out to avoid sesame seed allergy triggers.
2. Mustard allergy
Mustard allergies are more common in Europe but are increasingly being recognized in North America.
- • Common sources of mustard: Salad dressings, sauces, and processed foods
- • Symptoms: Hives, swelling, digestive distress
When cooking or dining out, ask if mustard is included, as it’s often a hidden ingredient and may be overlooked.
3. Citrus fruit allergy
Citrus fruits like oranges, lemons, and grapefruits are typically considered healthy, but for some people, they can trigger allergic reactions.
- • Common symptoms of citrus fruit allergy: Itching in the mouth, skin rashes, digestive discomfort
If you experience symptoms after eating citrus, consult an allergist, as reactions can vary and some may only be allergic to specific fruits.
4. Avocado allergy
Avocado is packed with healthy fats and nutrients, but it can also be a surprising allergy trigger for some people.
- • Who is most at risk for avocado allergy? People with latex allergies (latex-fruit syndrome)
- • Symptoms: Swelling, itching
If you have a latex allergy and experience these symptoms after eating avocado, it’s essential to consult with your doctor.
5. Red meat allergy
A red meat allergy might sound strange, but for some people, it can develop after being bitten by certain ticks, particularly the Lone Star tick.
- • Symptoms of red meat allergy: Hives, stomach upset, anaphylaxis
- • Cause: Tick bites leading to an allergy to red meat
If you’ve recently had a tick bite and are experiencing these symptoms, it’s important to talk to an allergy specialist.
6. Spice allergies (like cumin, coriander, and curry)
Spices are essential in many dishes, but for some, they can be a hidden source of allergens.
- • Common spice allergens: Cumin, coriander, curry powder
- • Symptoms: Hives, swelling, digestive distress
Spices can be hidden in many foods, so always check ingredient labels for potential allergens.
7. Soy sauce allergy
Soy allergies are relatively common, but many people overlook soy sauce, which contains fermented soy protein.
- • Where to find soy sauce: Asian-inspired dishes, sauces, marinades
- • Symptoms of soy sauce allergy: Itching, rash, stomach discomfort
If you have a soy allergy, consider using soy-free alternatives when cooking or dining out to avoid an allergic reaction.
8. Chia seed allergy
Chia seeds have become popular as a superfood, but for some people, they can cause allergic reactions.
- • Symptoms: Hives, itching, difficulty breathing
- • Hidden sources: Smoothies, energy bars, granola
If you’re new to chia seeds or have a history of food allergies, it’s wise to start small and monitor any reactions.
9. Buckwheat allergy
Though it sounds like wheat, buckwheat is actually not related to wheat at all. However, for some people, it can cause an allergic reaction.
- • Common sources of buckwheat: Pancakes, soba noodles, baked goods
- • Symptoms: Swelling, hives, gastrointestinal issues
People with other grain or nut allergies should be particularly aware of potential reactions to buckwheat.
10. Mushroom allergy
While mushrooms are a great source of vitamins and minerals, they can also cause allergic reactions in some people.
- • Symptoms: Digestive discomfort, skin irritation, difficulty breathing
- • Hidden sources: Sauces, soups, and salad dressings
If you experience symptoms after eating mushrooms, avoid them and consult an allergist to check for a mushroom allergy.
