What Is The Meaning of This?

Food Intolerance vs Food Allergy, What's The Difference?

Food Intolerance

A "non-allergic" food hypersensitivity. There are various physiological responses associated with a specific food or substance in food that produces symptoms in one or more body organs and symptoms.

Causes of Food Intolerance:

* Absence of an enzyme needed to fully digest food
*Irritable bowel syndrome
*Food poisoning
*Sensitivity to food additives
*Recurring stress or psychological factors
*Celiac disease


Signs &Symptoms of Food Intolerance

Physiologically similar to food allergy, but does not include the immune system. Symptoms begin generally 30 minutes after eating the food allergen. Food reaction occurs within hours of ingestion.

Food Allergies

A true food allergy is an exaggerated immune response triggered by a specific food or substance that is harmless for most people. The food protein is the allergen. These kinds of allergens happen when the body's immune system mistakenly identifies a protein as harmful. The immune system believes that it is under attack, sends white blood cells to attack, this triggers an allergic reaction. Allergic reactions range from mild to life threatening.

Signs & Symptoms of Food Allergy  

  • Hives
  • Itching or swelling
  • Nausea
  • Congestion or runny nose
  • Wheezing 
  • Abdominal pain
  • Lightheadedness or fainting
  • reactions within 30 minutes of ingestion





Disease Management

There is no cure for food allergy. If you have a food related reaction, see your doctor to diagnose whether you have food intolerance or food allergy. A diagnosis of adverse reactions to food is based on history, testing and response to treatment. Get the facts, learn about how to recognize a severe allergic reaction and what to do if one occurs.
