## Food Allergenicity Overview
* Understanding symptoms, mechanisms, and prevention strategies.

## Allergy vs. Intolerance
* Allergies involve the immune system (IgE antibodies) and can be life-threatening.
* Intolerance affects the digestive system (e.g., lactose intolerance) and is generally less severe.

## The Major Food Allergens
* Nine foods account for most serious reactions: Milk/Dairy, Eggs, Fish, Crustacean Shellfish, Tree Nuts, Peanuts, Wheat, Soy, and Sesame (added in 2023).

## Immunological Mechanism
* The immune system produces IgE antibodies in response to a food protein threat.
* Re-exposure triggers a release of chemicals like histamine from mast cells.

## Symptoms and Anaphylaxis
* Symptoms appear within 2 hours: hives, nausea, or respiratory issues.
* Anaphylaxis is a medical emergency characterized by airway constriction, drop in blood pressure, and rapid pulse.

## Diagnostic and Prevention Methods
* Diagnosis via medical history, Skin Prick Tests, IgE Blood Tests, or Oral Food Challenges.
* Prevention: Read labels for 'Contains' statements and avoid cross-contact in kitchens.

## Emergency Treatment
* Epinephrine (EpiPen) is the only effective treatment for anaphylaxis.
* Strategies include carrying two auto-injectors and regular expiration checks.
