What are Food Intolerances and Food Allergies

Food Allergies

The body’s immune system goes into overdrive when it comes into contact with an allergic substance. It mistakes the allergen for a parasite and works hard to repel it from the body. Food allergies are usually immediate reactions to certain foods that affect the immune system. Symptoms can occur soon after eating the food, such as redness and swelling of the lips, mouth and tongue. Urticaria (red itchy raised rash), stomach pains or vomiting are other common symptoms. Foods that cause allergies:

  • Shell fish
  • Peanuts
  • Strawberries

Allergies are very specific for example an individual maybe allergic to peanuts but not hazelnuts. The most reliable test for allergic reactions are the Prick or RAST (radio-immuneodiffusion test). This involves either a blood test or testing the skin directly with an allergen. These types of test do not recognise food intolerances.

A food allergy cannot be reversed and the food must be avoided for life.
An epi pen (adrenaline) is usually given to an individual in case of an emergency.

Food Intolerances

Food intolerance have a less immediate and intense reaction. Often symptoms may occur hours or days after eating the food. Instead of an intense immune response there is a normal immune reaction. This happens when partially digested food enters the blood stream triggering the immune reaction.

This reaction usually leads to long term problems as the offending food may not be detected immediately. The immune reaction could be occuring daily and draining the body’s vitality.

Symptoms such as anxiety, aching joints and muscles, fatigue, migraines, skin reactions, sinus problems, bloating, indigestion, abdominal discomfort, hyperactivity weight gain or difficulty losing weight.

Intolerances occur due to stress. This could be due to a busy lifestyle, working long hours, grief or trauma, antibiotics or medication and a regular consumption of convenience foods.

Common foods that cause intolerances:

  • Wheat
  • Dairy products
  • Stimulants (tea, coffee, chocolate and sugar)
  • Nightshade family (peppers, tomatoes, potatoes)
  • Citrus fruit

The Asyra system is one of the most reliable systems for screening food intolerances. It does not identify allergies and can not diagnose medical conditions. However, in a short space of time intolerances can be identified and treated through elimination, supplements and remedies. After a period of three months the body has usually had enough time to tolerate the food and this is confirmed in a follow up screening. Many individuals report a significant improvement in their symptoms and are able to reintroduce the intolerant food.

A food intolerance can be reversed after a period of elimination and recommended treatment plan.
