Whether you’re looking out for yourself, or a family member, or just want to be informed, it’s time to get familiar with some surprising food allergies. Some of these allergens are in foods you might eat regularly, so having this knowledge is a powerful tool. They might be closer to home than you think!
Corn
Corn is a common ingredient found in various products, from processed foods to snacks and even medications. However, those with a corn allergy may experience a range of symptoms when consuming products containing corn. Symptoms can vary from mild reactions like hives, itching, or digestive issues to more severe symptoms such as difficulty breathing or anaphylaxis. Since corn derivatives are widely used in many foods, identifying and avoiding them can be challenging, requiring careful label reading and awareness of hidden sources.
Red Meat
Red meat allergy, often linked to a bite from the Lone Star tick, can result in an unusual and potentially severe allergic reaction. Known as alpha-gal syndrome, this allergy is triggered by a carbohydrate called alpha-gal, found in mammalian meat such as beef, pork, and lamb. Symptoms may not appear immediately but can include hives, digestive discomfort, and in some cases, anaphylaxis. This delayed reaction makes red meat allergy particularly challenging to identify, requiring specific blood tests for confirmation.
Gelatin
Gelatin, a protein derived from animal collagen, is commonly used in products like marshmallows, gummy candies, and certain vaccines. For individuals allergic to gelatin, consuming these products can lead to adverse reactions, including hives, swelling, or even more serious symptoms like difficulty breathing. The allergy is often linked to a sensitivity to animal proteins, making it important for those affected to carefully avoid products containing gelatin. This allergy is often overlooked, yet it can have serious health implications.
Sesame
Sesame allergy has been on the rise and is now recognized as one of the top allergens, but many people are still unaware of its prevalence. Sesame seeds and oils are used in a variety of foods, particularly in baked goods, salads, and ethnic cuisines. Reactions to sesame can range from mild symptoms like itching and hives to severe anaphylaxis. Given the increasing presence of sesame in many foods, it’s important for those with this allergy to be vigilant and check food labels meticulously to avoid accidental exposure.
Lupin
Lupin is a legume that is often used in gluten-free and vegan products as a substitute for wheat or soy. Despite its benefits, lupin can cause allergic reactions in some individuals, particularly those who are already allergic to peanuts or soy. The symptoms can vary from mild reactions like itching or hives to more serious conditions such as anaphylaxis. Lupin allergies can be particularly tricky because lupin flour or seeds can be hidden in many food products, making it essential for those affected to be extra cautious.
Spices
Spices such as cinnamon, garlic, coriander, and others are integral to many dishes, but for some people, they can trigger allergic reactions. Spice allergies are often underdiagnosed because the symptoms can be subtle and resemble other conditions like respiratory issues or skin irritations. In more severe cases, spices can cause anaphylaxis. Those with spice allergies need to be vigilant about the ingredients in prepared foods, as spices are often used as flavorings or preservatives in many packaged and restaurant foods.
Sulfites
Sulfites are chemical compounds used as preservatives in foods like dried fruits, wines, and some processed products. While sulfites are generally safe for most people, they can cause adverse reactions in individuals with sulfite sensitivity, especially those with asthma. Symptoms can include respiratory issues, skin rashes, or even severe allergic reactions. Avoiding sulfites requires careful attention to food labels, as they are often listed under different names like sulfur dioxide, potassium bisulfite, or sodium sulfite.
Mango
Mango allergies, though relatively uncommon, can be serious for those affected. This allergy is related to a sensitivity to urushiol, the same substance found in poison ivy. People with this allergy may experience reactions such as itching, swelling, or hives, particularly around the mouth and lips. In severe cases, consuming mango can lead to more serious symptoms like difficulty breathing. For individuals allergic to mango, it’s important to avoid both the fruit and any products containing mango or mango derivatives.
Avocado
Avocado allergies are often linked to a condition known as latex-fruit syndrome, where individuals allergic to latex also react to certain fruits, including avocados. Symptoms of an avocado allergy can include oral allergy syndrome (OAS), which causes itching or swelling of the mouth, lips, and throat. In more severe cases, it can lead to anaphylaxis. Given the increasing popularity of avocados, individuals with this allergy need to be cautious about consuming dishes or products that contain avocados, whether raw or processed.
Sunflower Seeds
Sunflower seed allergies, while less common, can cause significant reactions in those affected. Symptoms can range from mild itching or hives to more severe respiratory issues or anaphylaxis. Sunflower seeds are often found in snacks, salads, and baked goods, making it essential for individuals with this allergy to be aware of the potential presence of sunflower seeds in various foods. Cross-contamination with sunflower oil can also pose a risk, especially in processed or restaurant foods.
Figs
Figs can cause allergic reactions, especially in individuals who are sensitive to birch pollen due to a condition known as oral allergy syndrome (OAS). Symptoms can include itching or swelling in the mouth and throat shortly after consuming figs. In some cases, the allergy can lead to more severe reactions, such as difficulty breathing or anaphylaxis. Those with a birch pollen allergy should be cautious when consuming figs or fig-related products and consider getting tested for cross-reactivity.
Garlic
Garlic allergies, although rare, can lead to uncomfortable and sometimes serious reactions. Symptoms may include skin rashes, digestive issues, or respiratory problems such as asthma or anaphylaxis. Garlic is a common ingredient in many dishes, and avoiding it can be challenging as it is often used in both fresh and powdered forms in cooking and food preparation. Individuals with a garlic allergy must be diligent in checking ingredient lists and communicating their allergies when dining out or purchasing prepared foods.
Bananas
Banana allergies are often associated with latex-fruit syndrome, where individuals allergic to latex may also react to certain fruits, including bananas. Symptoms can range from mild, such as itching or swelling of the mouth and throat, to more severe reactions like anaphylaxis. Bananas are a common fruit, and their presence in smoothies, desserts, and snacks means that those with this allergy need to be vigilant in avoiding them and carefully checking food labels for hidden banana ingredients.
