In practice, over the past 10 years is the most common question related to food intolerances,
What is the difference between food intolerances and food allergies?
The answer goes back to a research project and presentation of
food intolerances, We completed during our stay at Bastyr University .
Food allergies ( such as classically defined ) caused by IgE antibodies. Food intolerances are caused by IgG antibodies. Let me explain this science lesson.
" GI" is the scientific abbreviation of immunoglobulins, which is another name for antibodies, the immune system messengers. The letter "E" and "G" are assigned to each antibody for its unique properties. ( Would not it be fun to rename it something more?
IgE antibodies to work faster and more severe reactions such as hives, swelling, and anaphylaxis. If a person on a food or substance that causes such a reaction is subjected to emergency care often necessary. This is the
"classic food allergy" as peanuts or shrimp tested by allergy with a skin test.
IgG, on the contrary, work slowly, and even cause up to 72 hours to be much more subtle and mysterious symptoms, such as fatigue, constipation, sinus, digestive disorders and / or uncomfortable, but symptoms non-emergency throughout the body. Unfortunately, in our opinion, did not include the IgG levels of care in conventional medical care. Therefore, it is to be the first to understand that you can be.
While many people are familiar with " lactose intolerance ". We are satisfied with the immune system launches an attack on the food you eat, then what about deterious effects in a number of areas of the body.
The most common symptoms associated with IgG food intolerance include headache, fatigue, constipation / diarrhea, eczema / psoriasis, frequency / of urinary urgency, susceptibility to infection ( in the body), anxiety / depression and the gain / loss of weight. These symptoms may potentially cause, and how to be in serious diseases such as autoimmunity, chronic fatigue and cancer a few names. The types of foods that are probably involved in this condition: milk, gluten ( protein in wheat products ), eggs and nuts.
When you practice a specialty hospital allergy I started noticing that people who are intolerant ( "sensitive" is another term used) to extend a gluten intolerance many other foods, as well as some fruits and vegetables and foods that often in their diet.
This phenomenon is known as" leaky gut" or medically known as intestinal permeability. One way to think of it as if the lining is like a sieve, instead bowl.
As we first learned during our university studies, remains to be fully digested in a healthy digestive tract and pass through the cells of the intestine into the bloodstream. In this case, the immune system is located between the inner wall of the intestines and blood vessels, only nutrients, never exposed to real food particles.
Thus, IgG antibodies are produced, the immune system must debris, which means that the intestinal mucosa has been compromised, so the partially digested food to be exposed to arrive between cells. Therefore, the sieve effect, called intestinal permeability.
A common culprit causing Leaky Gut is gluten, which is why people who are intolerant to gluten often intolerant of many other foods. In fact, most of the time the food down by the digestive tract frequently. ( It is not uncommon for people who eat the same foods over and over again . ) Another common cause is too frequent exposure to antibiotics and / or disruption of the balance of healthy bacteria in the gut.
