The definition of food allergy pertains to an adverse immune response to a particular food protein. This reaction can manifest in a variety of symptoms, ranging from mild to severe, and can occur within minutes to hours after ingestion. Food allergies include peanuts, tree nuts, shellfish, fish, dairy, nuts, soy, and wheat. The prevalence of food allergies has increased in recent years, affecting approximately 8% of children and 4% of adults in developed countries. Proper diagnosis and management of food allergies are crucial to preventing potentially life-threatening reactions and improving the quality of life for those affected.

The categorization of food allergies is a subject of great importance in the medical field. There are several classifications of food allergies, including IgE-mediated, non-IgE-mediated, and mixed IgE/non-IgE-mediated. IgE-mediated allergies are the most common and are characterised by the production of IgE antibodies in response to a specific food allergen. Non-IgE-mediated allergies involve a delayed immune response and can cause symptoms such as eczema or gastrointestinal distress. Mixed IgE/non-IgE-mediated allergies exhibit characteristics of both types. Proper identification and classification of food allergies is crucial for effective treatment and management of symptoms.

Any kind of food can cause an allergy. About 90% of all food allergies are caused by eight different food kinds. These meals include:

• Eggs.
• Fish.
• Milk.
• Peanuts.

• Wheat.

Your doctor may recommend medications to lessen the symptoms of an allergic reaction. These medications consist of:

Epinephrine is a life-saving emergency drug that startsreversing anaphylactic symptoms right away (such as EpiPen® or Auvi-Q).Antihistamines are drugs that ease congestion or irritation.If you experience a severe allergic reaction, you can use corticosteroids to minimize swelling.
