1. Which is not in the top nine food allergens?

A. Milk, eggs, and wheat
B. Fish, crustacean shellfish, and strawberries
C. Sesame and wheat
D. Tree nuts, peanuts, and soybeans

2. A person with a suspected food allergy needs to eliminate the allergen from their diet. People with a suspected food allergy remove the suspicious foods from their diet and slowly add the foods back into their diet, one at a time, to identify the allergen.

3. Cross-reactivity means that the protein in the allergic food is similar to that in other foods, and the person's immune system cannot tell the proteins apart, thus reacting to similar foods.

4. Oral allergy syndrome is caused by cross-reacting allergens found in pollens, raw foods, and tree nuts.

5. An allergy to a specific sugar molecule found in mammals, including gelatin, some vaccines and medications, cosmetics, and milk products, is referred to as alpha-gal syndrome.

6. People with celiac disease are put on a gluten-free diet.

Answer :

  1. The top nine food allergens include milk, eggs, wheat, fish, crustacean shellfish, tree nuts, peanuts, soybeans, and sesame. Strawberries are not included in this list. Therefore, the correct answer to the question is option B: Fish, crustacean shellfish, and strawberries.

  2. A person with a suspected food allergy typically follows an elimination diet. This involves removing the suspected allergen from their diet completely. After a period of time, they gradually reintroduce the removed foods one by one. This method helps identify the specific food that causes the allergic reaction, as introducing one food at a time allows them to observe any reactions.

  3. Cross-reactivity occurs when the proteins in an allergenic food have a similar structure to proteins found in other foods. As a result, the immune system may mistakenly react to the similar foods, leading to an allergic response. Understanding cross-reactivity is important for managing allergies because it helps identify other foods that might cause similar reactions.

  4. Oral allergy syndrome (OAS) is an allergic reaction that occurs when someone with a pollen allergy reacts to cross-reacting allergens found in raw foods, certain tree nuts, and some vegetables and fruits. It typically causes itching or swelling of the mouth and throat. OAS is more common in people who have hay fever.

  5. Alpha-gal syndrome is an allergy to a sugar molecule called galactose-alpha-1,3-galactose, found in mammals. This condition can result in an allergic reaction to red meat and other products derived from mammals, including gelatin and certain medications. It's usually triggered by a tick bite which leads to the development of this allergy.

  6. People with celiac disease cannot tolerate gluten, a protein found in wheat, barley, and rye. Exposure to gluten can damage the lining of their small intestine. Therefore, individuals with celiac disease must follow a strict gluten-free diet to manage their condition and prevent symptoms such as gastrointestinal discomfort and nutrient deficiencies.
