What is a common food allergen that older adults should be cautious of?

Shellfish is indeed a common food allergen that older adults should be cautious of. As individuals age, their immune systems can undergo changes, potentially leading to an increased risk of developing food allergies or experiencing allergic reactions to foods they have previously consumed without any issues. Shellfish allergies, in particular, are known to persist throughout a person's life, making it essential for older adults to be aware of this allergen.

Shellfish includes both crustaceans (such as shrimp, crabs, and lobsters) and mollusks (like clams, mussels, and oysters). Reactions can range from mild symptoms, such as hives or gastrointestinal upset, to severe anaphylactic responses. The risk is compounded because many older adults may also take medications that can further complicate allergic reactions or co-occur with other health issues, making it crucial for them to identify and avoid potential allergens like shellfish to maintain their health and well-being.

While other foods such as nuts, wheat, and dairy are also recognized allergens and can cause reactions, the specific focus on shellfish highlights its relevance and prevalence among the older population. Being informed about shellfish allergies helps in managing and preventing allergic reactions, which can be particularly serious in this age group.
