🫓Sesame allergy
Sesame allergy is a food allergy that can cause severe reactions, and sesame is now a labelled major allergen in the EU, UK and US. It is managed by avoiding sesame completely and being ready to treat a reaction.
🔬What it means
In a sesame allergy the immune system mistakes sesame proteins for a threat and releases chemicals such as histamine. Even a small amount can trigger a reaction in some people.
Sesame must be highlighted in the ingredients in the EU and UK, and in the US it has been a major allergen on labels since 2023. Outside these regions, and in food that is not pre-packed, sesame may not be clearly declared.
✅What you can eat
- 🥩Naturally sesame-free foods: plain meat, fish, eggs, dairy, grains, fruit and vegetables.
- 🍞Bread and buns without seeds — but check the label, as bakeries often handle sesame.
- 🌱Other seeds and nuts only if your allergist says they are safe for you; some people react to more than one.
🚫What to avoid
- 🫓Sesame in any form: seeds (white, black, toasted), sesame flour, sesame paste (tahini).
- 🫗Sesame oil: it is usually unrefined and can contain enough protein to cause a reaction.
- 🧆Middle Eastern dishes: hummus, baba ganoush, tahini sauce with falafel or shawarma, halva, za'atar, dukkah, some breads and pastries.
- 🍜Asian dishes: many Chinese, Japanese and Korean dishes and dressings, sesame noodles, sushi rolls with seeds, furikake, gomasio.
- 🍔Baked goods and snacks: burger buns and bagels with seeds, breadsticks, crackers, cereal bars, some veggie burgers.
- 🏷️Labels and “may contain”: “May contain sesame” means there is a risk of traces — most allergists advise avoiding these products. In restaurants, tell the staff every time.
⚠️What happens during a reaction
Symptoms usually start within minutes to two hours: itchy mouth, hives, redness, swelling of the lips or face, stomach pain, vomiting, sneezing or a runny nose.
A severe reaction — anaphylaxis — affects breathing or circulation: swelling of the tongue or throat, hoarse voice, wheezing, difficulty breathing, feeling faint, pale or clammy skin, collapse. It can develop fast and is life-threatening.
A mild reaction last time does not mean the next one will be mild. People with asthma are at higher risk of a severe reaction.
🚑When to get help urgently
If there are any signs of anaphylaxis, use an adrenaline auto-injector if you have one and call emergency services immediately, even if symptoms improve. Lie down with legs raised (or sit up if it is hard to breathe) and do not stand up suddenly. After any reaction, see a doctor about an allergy plan.
