What Is a Food Allergy and Food Intolerance?

What Is a Food Allergy?

A food allergy is an immune system response triggered by specific proteins in certain foods.
It occurs when the immune system mistakenly identifies harmless food proteins as harmful invaders.
The body releases histamines and other chemicals in response, leading to various allergic symptoms.
Food allergies can be severe and life-threatening, causing anaphylaxis in some cases.
Common food allergens include peanuts, tree nuts, shellfish, fish, eggs, milk, wheat, soy, and certain fruits.

What Is a Food Intolerance?

Food intolerance is a non-immune response to certain foods, often caused by digestive issues.
It occurs when the body lacks specific enzymes or has difficulty digesting certain substances in food.
Unlike allergies, food intolerances do not involve the immune system and are generally not life-threatening.
Symptoms of food intolerance can be mild to moderate and may include bloating, gas, diarrhea, or abdominal pain.
Common food intolerances include lactose intolerance, gluten sensitivity, and sensitivity to food additives like sulfites or MSG.

Medications and Treatments:

Antihistamines: Antihistamines are commonly used to treat mild allergic reactions by blocking the action of histamines, the chemicals responsible for allergy symptoms such as itching, sneezing, and hives. They can provide relief for symptoms like runny nose, itching, and mild skin reactions.
Epinephrine Autoinjectors: Epinephrine is the first-line treatment for severe allergic reactions, known as anaphylaxis. Epinephrine autoinjectors, such as EpiPen, deliver a dose of epinephrine to quickly reverse life-threatening symptoms, including difficulty breathing, swelling of the throat, and a drop in blood pressure. People with severe allergies should carry epinephrine with them at all times and know how to use it properly.
Allergy Shots (Immunotherapy): Allergy shots, or immunotherapy, involve regular injections of small amounts of allergens to gradually desensitize the immune system. This treatment aims to reduce allergic reactions and symptoms over time. It is commonly used for environmental allergies but is still being researched for food allergies.
Enzyme Supplements: For food intolerances, enzyme supplements may help improve digestion by providing the enzymes lacking in the body to break down specific substances. For example, lactase supplements can aid those with lactose intolerance in digesting lactose.
Avoidance and Elimination Diets: The primary treatment for food allergies and intolerances is strict avoidance of trigger foods. Elimination diets involve removing potential allergens or intolerant foods from the diet to identify specific triggers and prevent further reactions.
Supportive Care: In cases of mild allergic reactions, over-the-counter medications like pain relievers and creams can help manage symptoms such as pain, swelling, and itching.
Corticosteroids: In severe cases of allergic reactions, corticosteroids may be prescribed to reduce inflammation and suppress the immune response. These are typically used for short-term management and under medical supervision.
Probiotics: Probiotics are beneficial bacteria that can support gut health. While more research is needed, some studies suggest that probiotics may help alleviate symptoms of food intolerances.
Education and Training: Learning how to recognize symptoms and respond appropriately in case of allergic reactions is essential. Training on the use of epinephrine autoinjectors is crucial for individuals with severe allergies and their caregivers.
Allergen Immunotherapy: Experimental treatments like oral or sublingual immunotherapy aim to desensitize the immune system to specific food allergens. These treatments are still being studied and should only be considered under medical supervision in research settings.
