Food Allergies and Intolerances: Understanding Dietary Restrictions and Accommodations

There are several common food allergens that can trigger adverse reactions in individuals with allergies. These allergens include peanuts, tree nuts, eggs, dairy, soy, wheat, fish, and shellfish. For some people, even small amounts of these allergens can lead to severe allergic responses, ranging from hives and swelling to anaphylaxis, a life-threatening reaction.

It is important for those with food allergies to carefully read food labels and ask about ingredients when dining out to avoid potential allergens. Being aware of common food allergens and taking necessary precautions can help prevent allergic reactions and ensure the safety of individuals with food allergies.

Difference Between Allergies and Intolerances

Food allergies and intolerances can often be confused because they both involve adverse reactions to certain foods. However, the key difference lies in the immune system’s response. With allergies, the immune system reacts to a specific food protein as if it were harmful, triggering symptoms that can range from mild itching to severe anaphylaxis.

On the other hand, food intolerances do not involve the immune system but rather the digestive system’s inability to properly break down or process certain foods. This can lead to symptoms such as bloating, diarrhea, or stomach cramps. Unlike food allergies, intolerances are typically non-life-threatening, although they can still significantly impact an individual’s quality of life.

How do food intolerances manifest in the body?

Food intolerances can cause symptoms like bloating, gas, diarrhea, and stomach cramps, but do not involve the immune system’s response like allergies do.
