Much to my surprise, I recently discovered that there are still people out there that do not know what gluten is. This says less about them than it does about me. I am so used to studying food, learning about food, and preparing food that I forget there are people out there who don’t actually spend a lot of time doing this. So today’s post is a small primer on gluten: what is it, and what is it good for?
Gluten is a protein found in certain grains. It is also present in the flour that is made from these grains. For those of you who prefer a bit more precision, gluten is actually a composite of two different proteins, gliadin and glutenin. Gluten acts primarily as a binding agent.
Because of it`s binding qualities, gluten provides not only cohesion but elasticity and strength to the dough. It is gluten that makes baked goods so wonderfully chewy and airy at the same time. It also adds tenderness to the finished product.
Gluten can be found in a number of flours. Specifically, gluten is present in wheat , rye, kamut, barley, oat, and spelt flours. The amount of gluten found in each of these flours differs. Therefore, the same recipe can produce entirely different results if flour is simply substituted.
The inclusion of oats on the list is controversial, as some people with gluten sensitivities find they can ingest oats without any problems. Some people are so sensitive that the smallest contact with an item containing gluten can provoke a reaction. Cross contamination can therefore be a problem.
For a growing number of people, gluten can cause irritation to the digestive system. Gluten can even cause even damage to the small-bowel. Many people believe that there are different degrees of gluten sensitivity, just as there are different degrees of food sensitivities.
The most extreme reactions to gluten can be found in people with Celiac disease. For those with Celiac disease, the immune system reacts to the gluten, resulting in an inflammatory reaction in the small intestine, eventually leading to damage to the villi that line the small-intestine. Once the villi are damaged, there is a significant danger of malabsorption of nutrients. This can lead to the development of some serious health problems. However, once gluten is no longer ingested, the symptoms will usually reverse themselves over time. Typically, there are a number of physiological symptoms indicating the presence of Celiac disease, but only a few of them are related to the gut. Celiac presents differently in every person, making it a difficult disease to diagnose.
Gluten intolerance (or sensitivity) differs from Celiac as it is rarely, if ever, as severe as Celiac disease. This is not to say that there are not a lot of people who do not suffer horrendously because of gluten. However, it is unlikely that this intolerance is life-threatening. Furthermore, most people with an intolerance can occasionally ingest gluten without suffering any adverse effects, especially if they have taken the time to heal their digestive system properly by avoiding gluten studiously for a period of time. This is not the case for people with Celiac disease. An intolerance to gluten often presents in a similar manner as Celiac disease, although the symptoms are typically not as severe. The best (and cheapest) method for checking to see if you have a gluten intolerance is to omit gluten from you diet, and see if your health improves.
Since there is no medically decisive test to establish the presence of a food intolerance/sensitivity, it is not a condition that is widely recognized by medical doctors. Some doctors will acknowledge its existance, whereas others will deny the role that food plays in your health virtually outright. Alternative health practitioners, on the other hand, will generally accept the existance of these conditions. As such, they are typically more willing to work with the patient in treating these problems.
If you are avoiding gluten, it is important to remember that gluten can be isolated and used in unexpected places. It can therefore be added to items that you might otherwise not suspect had any gluten in them. For example, it can be used in ice cream as a thickener, or to processed foods as a binding agent. Even items as innocuous as baking powder must be questioned. Gluten can also be found in various imitation meats, such as Seitan.
There is a wealth of information about Celiac disease. Even if you do not have Celiac, but wish to omit gluten from your diet for other reasons, it is well worth visiting some of the websites out there to gather information on how to manage your new diet. There are a number of websites dedicated to group forums that can offer much more advice than most doctors can.
