Unless you’ve been living under a rock, you’ll likely have heard about the gluten free ‘fad’ in the wellness community. Especially if you have any kind of chronic illness. More and more are being diagnosed with Celiacs disease, but even some without Celiacs are reporting with symptoms of gluten intolerance. These cases are referred to as gluten intolerant or non celiac gluten sensitive individuals.

People have very strong opinions when it comes to this and you may have heard the following comments about it:

• ‘gluten free is a fad’

• ‘non celiac gluten sensitivity is a hoax’

• ‘cutting gluten when you don’t have to is harmful’

And I’m sure you don’t want to hear this, but I hate to say that these comments (that we even sometimes here form our doctors and practitioners) are not supported by the science.

There is an ever growing pile of evidence proving that gluten increases inflammation, contributes to a leaky gut, preferentially feeds harmful gut bacteria and is associated with a growing list of conditions seemingly every day.

And this doesn’t just apply to those with illness, there is further evidence to support that gluten causes intestinal damage to everyone, ‘healthy’ individuals included.

Let’s dig into the science and debunk what these naysayers have to say about gluten.

You’ll often hear that gluten is an inflammatory food. This is due to a few reasons. It’s effects on the gut, the way it’s prepared, and the fact that it is often treated with harmful chemicals such as Glyphosate.

LEAKY GUT

What is a leaky gut? I’ll be sure to do another post detailing what exactly it is, but to sum, a leaky gut is when something happens to the integrity of the lining of the small intestine, and food particles, toxins and other things that do not belong outside of the small intestine get into circulation.

This is bad news bears for multiple reasons.

1. This activates the immune response and immune cells mount an attack on this foreign invaders. “But it’s just food?” you may be thinking. Well sometimes yes, and sometimes no. Not all of our food is pure- think of things such as herbicides and germs that are commonly on our food. Or parasites from meat or fish that the body usually would deal with during the digestive process. These things can leak into the body as well and cause damage to our tissues. In addition, our circulation is meant to handle individual isolated nutrients, not undigested food particles. So the immune system will treat these as harmful substances and will seek them out. If our gut is leaking, this means every time we eat we are leaking food into our circulation and activating the immune response.

2. Nutrient deficiencies. Obviously if we are leaking our nutrients into our circulation, we are not absorbing and assimilating them for proper use in the body. Additionally, the immune system is an immune hog on a good day, let alone when it is constantly being triggered. More immune action=more nutrients used, and less to go around for other metabolic functions.

3. Inflammation. These foreign substances can damage surrounding tissues and cells, creating a chronic inflammatory state. Again, this damage requires nutrients to heal, further adding to the nutrient deficit.

So leaky gut = a big problem. A leaky gut is the gateway to many autoimmune diseases. In fact, every single autoimmune disease studied has been linked to a leaky gut.

And as you know if you follow me on Instagram, while endometriosis is not considered an AI disease (yet!) there is a very strong immune component to the disease AND there is also a very strong link between endometriosis and a leaky gut. So this applies to all of my endosisters as well.

GLUTEN + A LEAKY GUT

The reason I bring this up is because gluten exposure has been shown to cause and worsen a leaky gut. This is due to it’s  direct effect on the cells of our intestines.

Prolamins are a component of all grains and pseudograins (amaranth, quinoa etc) and is very prominent in Gluten, in particular the protein component of gluten called Gliadin. 

Prolamins resist proper digestion because we lack the necessary enzymes to do so, but also because they are rich in protease inhibitors such as phytic acid, which are not only very tough to digest (hello bloat!) but also can bind to our minerals, making these compounds known as ‘anti nutrients.’

Prolamins trigger the release of a substance known as Zonulin, a protein that regulates the opening and closing of our gut junctions, which are basically the structures that glue our epithelial cells (the cells that line our intestines). Zonulin is meant to be a part of the normal digestive process, and one of it’s functions is to assist in the selective nutrient absorption of certain nutrients, but the problem arises when there is too much zonulin secretion.

Think of how often gluten is consumed. Toast, bagels, pastries or english muffin for breakfast. A sandwich or wrap for lunch. Pasta or garlic bread for dinner. Not to mention cookies, cakes, pies that make up dessert and our favorite snacks. 

You can see how this adds up to an unhealthy zonulin production, and contribution to a leaky gut. 

GLUTEN & THE MICROBIOME

If that wasn’t already enough science to convince you to try going gluten free, here’s some more compelling information. Gliadin is known to inhibit enzyme activity. Enzymes help to break down our protein into individual amino acids, or complex sugars into monosaccharides. When gluten interferes with these processes, it leaves a lot more of our food not broken down into utilizable nutrients, and it can then act as fodder for our gut bacteria. This can lead to gut dysbiosis- an imbalance in the gut bacteria. This is what leads to pathogenic gut conditions such as SIBO or Candida.

In other words- gluten feeds the bad bacteria in our gut. 

NUTRIENT CONTENT (OR LACK THEREOF)

Gluten containing foods are often high caloric- meaning they are high calorie. They are also often lacking in nutrients. Most gluten items are made from refined flour. The refining process essentially strips any and all nutrition from the foods. After the second world war many food companies began to notice the increase in nutrient deficiencies and began to fortify these foods with synthetic vitamins to correct the deficiencies. Now people think of these grains and refined flours as high in certain nutrients, such as iron, folic acid (see my article about folic acid vs folate here), and fiber. This is often touted as a reason to not go gluten free because then you will be lacking in these nutrients.

This is a gross fallacy. With all of that room for additional calories/fuel in your diet you will have to reach for whole food forms of fuel- such as veggies, fruits, meats etc. And these foods have a much more diverse and substantial nutrient content than any gluten containing food.
