Recognising and Understanding Sesame Allergy

How do I know if I am allergic to Sesame?
Identifying a sesame allergy involves noticing specific allergic reactions after consuming sesame or sesame-containing products. Common symptoms include skin reactions like hives or eczema, gastrointestinal discomfort such as nausea or vomiting, respiratory issues including wheezing or nasal congestion, and in severe cases, anaphylaxis, which is a life-threatening reaction. If you suspect a sesame allergy, it's crucial to consult an allergist. Diagnostic methods typically include skin prick tests, where a small amount of sesame protein is introduced to the skin, or specific IgE blood tests that measure the immune system's response to sesame proteins.

What are the signs and symptoms of a sesame allergy?
The signs and symptoms of a sesame allergy can vary significantly from person to person. Mild symptoms might include itching or tingling in the mouth, hives, and minor gastrointestinal discomfort. More severe reactions can involve swelling of the lips, face, throat, or other parts of the body, abdominal pain, diarrhoea, nausea or vomiting, nasal congestion, difficulty breathing, and a drop in blood pressure. Anaphylaxis, the most severe reaction, requires immediate medical intervention as it can be life-threatening.

Is it common to be allergic to Sesame?
While sesame allergy is less prevalent than allergies to foods like nuts, milk, or eggs, its incidence is on the rise. This trend might be linked to increased globalisation and the incorporation of sesame into various cuisines and products. In some regions, particularly in the Middle East and Asia, sesame is a common part of the diet, leading to higher rates of sensitisation and allergy.

Why are people becoming allergic to Sesame?
The reasons behind the increase in sesame allergies are multifaceted. Genetic predisposition plays a significant role; individuals with a family history of allergies are more likely to develop food allergies, including to sesame. Environmental factors, such as changes in food processing methods and increased consumption of sesame in various forms, also contribute. Additionally, the 'hygiene hypothesis' suggests that reduced exposure to infections during early childhood may impact the development of the immune system, leading to a higher incidence of allergic diseases.

Demographics, Duration, and Variability of Sesame Allergies

Who is prone to be allergic to Sesame?
Sesame allergy can affect individuals of any age, but it is more commonly diagnosed in children. However, unlike some food allergies that children outgrow, sesame allergies tend to persist into adulthood. People with a personal or family history of allergies, particularly other food allergies or allergic conditions like asthma or eczema, are at a heightened risk. Ethnicity and dietary habits also influence susceptibility, with higher rates observed in regions where sesame is a staple food.

How long does a Sesame allergy last?
The duration of a sesame allergy varies. In some children, the allergy may be outgrown, but in many cases, it persists into adulthood. Regular follow-up with an allergist can help assess if the allergy is ongoing. Periodic re-evaluation may include monitoring of symptom history and repeat allergy testing to determine if the allergy is still present.

Can you suddenly become allergic to Sesame Seeds?
Yes, it is possible to develop a sesame allergy suddenly, even if you have consumed sesame without any issues in the past. Allergies can develop at any age due to changes in the immune system's response to certain proteins found in sesame seeds. This sudden onset can be surprising and may occur in adults who have eaten sesame for years without problems.

How do you reverse a Sesame allergy?
Currently, there is no cure for sesame allergy, and the main treatment is strict avoidance of sesame and products containing sesame. However, research is ongoing in the field of oral immunotherapy (OIT), where small, controlled amounts of the allergen are ingested in an attempt to desensitise the immune system. While promising, this approach is still experimental for sesame allergy and should only be conducted under close medical supervision due to the risk of severe allergic reactions.

Specifics of Sesame Allergy and its Distinctions

Why am I allergic to Sesame Seeds but not oil?
The allergic reaction to sesame is typically triggered by proteins in the seeds. Sesame oil, especially highly refined oil, may have these proteins removed during processing, reducing the likelihood of an allergic reaction. However, it's important to note that unrefined or cold-pressed sesame oil may still contain enough protein residues to cause a reaction in some individuals. Therefore, it's recommended that people with sesame allergy avoid all forms of sesame, including oil, unless an allergist confirms it's safe.

When did Sesame become a major allergen?
Sesame has been recognised as a significant allergen in various parts of the world for some time, especially in countries where it's a common part of the diet. However, its recognition as a major allergen in Western countries has been more recent. In the European Union, sesame has been listed as one of the 14 major allergens that must be declared on food labels since 2003. In the United States, the FASTER Act, signed into law in 2021, added sesame to the list of major food allergens requiring clear labelling, effective from January 1, 2023.

Why am I allergic to Tahini but not sesame?
Tahini, a paste made from ground sesame seeds, contains the same proteins found in sesame seeds that can trigger allergic reactions. If you are allergic to sesame seeds, it's likely you will react to tahini as well. However, there can be variability in processing methods and purity levels that might affect allergenicity. Some individuals might react to one product and not another, depending on factors like the degree of processing, which can alter the protein structure and potentially reduce allergenicity.

Is a Sesame allergy the same as a nut allergy?
While sesame allergy and nut allergies are both food allergies, they are caused by different proteins and are not the same. People with a sesame allergy are allergic to specific proteins in sesame seeds, whereas those with nut allergies react to proteins in nuts. It's important to note that having a sesame allergy doesn't automatically mean you're allergic to nuts, though some individuals may have multiple food allergies, including both sesame and nuts.

Avoidance Strategies and Dietary Considerations

Who should avoid Sesame?
Anyone diagnosed with a sesame allergy should avoid sesame in all forms to prevent allergic reactions. This includes foods containing sesame seeds, sesame oil, and products like tahini. It's also advisable for individuals who have experienced symptoms suggestive of a sesame allergy but have not yet been formally diagnosed to avoid sesame until they can be evaluated by a healthcare professional.

What foods contain Sesame?
Sesame is commonly found in a variety of foods, including bread, crackers, hummus, tahini, and certain Asian and Middle Eastern dishes. It's also used in dressings, marinades, and as a garnish on various foods. Additionally, sesame can be found in some snack bars, cereals, and confectionery items. Always read labels carefully, as sesame can be present in unexpected products.

Does bread contain Sesame?
Many types of bread, especially certain artisan and whole-grain breads, can contain sesame seeds either baked into the crust or sprinkled on top. However, not all bread contains sesame, so it's important to check the ingredient list or ask the baker if you're purchasing freshly baked bread.

Is there sesame in flour?
Regular flour does not contain sesame. However, cross-contamination can occur in facilities that process both sesame and flour products. For those with severe sesame allergies, it's advisable to choose flour brands that guarantee a sesame-free processing environment.

Does hummus have sesame?
Traditional hummus recipes include tahini, which is made from sesame seeds. However, some commercial hummus varieties may be made without tahini or use alternative ingredients. Always check the ingredient list if you have a sesame allergy.
