Food Intolerances And Allergies - Is It Just In Your Head
By Craig Burton
Food intolerance has become a major health issue today, dividing conventional and alternative medicine.
1. Are we a bunch of hypochondriacs?
"An astonishing 45% of us believe we are allergic to basic foodstuffs such as wheat and dairy - causing anything from headaches to bloating and insomnia." (1) So how do we get to a stage of leaky gut?
It is believed that through one of the most common digestive problems the irritable bowel syndrome (IBS) arise.
It is believed by many health practitioners Leaky gut is associated with one of the most common digestive problems; irritable bowel syndrome (IBS).
2. Definitions
Food allergy - Is a genetic condition that affects about 2% of the population. The reaction to the food can range from a rash to something very severe including anaphylactic shock. The RAST test confirms this by detecting the antibody (like IgE). Common foods associated with a genetic inherited allergy are: cows milk, soy, tree nuts, eggs, strawberries, bananas, chocolate, wheat, peanuts, fish, shell fish, beans and oranges. Those with a true food allergy if ever exposed to that food more than once will know about it. (2)
Food intolerance/sensitivity - Involves any adverse reaction to foods, but whereby the immune system's roll is uncertain because the standard tests appear negative. There are other tests including the ones outlined in the Daily Mail but the validity of many is questionable. (2)
So where does this leave the 45% who experience real problems like abdominal bloating, gas, diarrhoea after eating a particular food? Furthermore, according to the Allergy Clinic scientific studies have suggested that intolerance may trigger or worsen the symptoms of a range of common conditions including asthma, joint and muscle pains, headaches, migraines, sinusitis, hyperactivity, ADHD, chronic fatigue, and Crohn's Disease. (3)
Possible sources of food intolerance
There is a strong suggestion that the increased permeability of the gut wall, known as leaky gut syndrome (LGS), is behind food intolerance. The basic premise behind LGS is that large molecules pass through the weak (leaky) gut wall and enter into the bloodstream. This results in calling to arms the body's defensive mechanisms like white blood cells that produce antibodies to destroy the invaders.
So how do we get to a stage of leaky gut?
It is believed that through one of the most common digestive problems the irritable bowel syndrome (IBS) arise.
According to Dr. Dan Rutherford, GP, IBS is the commonest condition seen by doctors and some estimates suggest that as many as one in five of the adult population in the UK suffer from it at any one time. (4)
So what is the source of IBS?
Experts give a range of probable causes including:
• Poor diet (including eating foods our bodies are not accustomed to)
• Toxins
• Lack of stomach acid or digestive enzymes
• Drugs (antibiotics, cortisone)
• Dysbiosis (leading to a bad bug overgrowth, e.g. Candida)
• Stress
• Inadequate chewing
As you can see this is a controversial topic because of the lack of hard evidence.
The Daily Mail (Tuesday, March 7th, 2006) contained an article called "The Allergy Fraud" from the reporter Charlotte Dovey. After receiving a RAST test (a blood test indicating an allergy) from a Harley Street doctor she was told she suffered from no food allergies. Then Ms Dovey compared the RAST result with other various methods of allergy detection from alternate medicine practitioners. Or as the reporter put it: entered the "wacky world of food intolerance testing".
Now Ms Dovey, who was told by various alternate practitioners that she was intolerant to a range of foods like wheat, dairy and citrus (when the RAST test showed no allergies) concludes: "if I took this advice, my diet could be dangerous. Basics such as wheat, gluten, sugar and lactose are staples". (However this I believe
