Understanding Gluten and Why It Matters in Your Diet
Gluten is prevalent in contemporary diets, particularly for individuals who often have issues with food sensitivities, intolerances, allergies, or celiac disease. The goal is to understand what gluten is, what people avoid for health reasons, and where oats fit into the gluten-free picture.
What is gluten and why avoid it?
Gluten is a naturally occurring protein found in wheat, barley, and rye. Gluten helps dough rise and gives it an elastic and chewy texture. This is why gluten is so prominent in breads, pastries, and pasta.
Reasons for avoiding gluten:
- Celiac disease–celiac disease is an autoimmune condition in which gluten will cause damage to the lining of the small intestine.
- Gluten sensitivity–people who do not have celiac disease can often still experience symptoms such as bloating, headaches, and fatigue.
- Wheat allergy–some people are allergic to gluten grains.
For these individuals, the consumption of gluten, with even traces, can cause discomfort or health issues, which is why gluten free is so vital to the way they eat.
How gluten affects those with celiac disease and sensitivity
Celiac disease requires a strict gluten-free diet. When someone with celiac disease eats gluten:
- The immune system attacks the small intestine.
- This can result in nutrient malabsorption, chronic intestinal issues, anemia, osteoporosis and fatigue.
In comparison, non-celiac gluten sensitivity may not physically harm the intestine the same way, but still causes:
- Bloating
- Brain fog
- Abdominal cramping
- Emotional ups and downs
For either individual, exclusion of gluten from the diet can provide meaningful improvements to health and reduce any serious complications in the future.
Are oats gluten free foods by nature?
Yes, technically. Oats are gluten free foods by nature.
- Oats have neither wheat, rye or barley protein.
- Oats do contain avenin, a gluten-like protein, but it generally does not cause a response for most people who have celiac disease.
However, there is a large caveat:
- Most oats are processed in facilities with gluten-containing grains.
- This leads to cross-contamination and most conventional oats are not safe for gluten sensitive persons.
To enjoy oats safely:
- Choose "Certified Gluten Free" brands.
- These oats were grown, processed and packaged in gluten free environments.
Are Oats Gluten Free by Default or Only When Certified?
Oats are well-known as a whole grain that contains fiber and is heart-healthy. However, when we turn to the topic of gluten, things get muddled—are oats gluten free by themselves? Or are they gluten free only when stated? This really comes down to both their biological make-up and how they are handled in the processing stream.
The natural composition of oats: are all oats gluten free?
- Yes, oats, by default, are gluten free. Oats do not contain the gluten proteins found in wheat, rye, or barley.
- However, that does not mean that all oats are gluten free, especially when purchased commercially.
- The vast majority of oats that can be purchased were processed in shared facilities, which often results in contamination from gluten containing grains.
That is why if you have celiac disease or a gluten sensitivity, it is imperative to use certified gluten free oats, so as not to expose yourself to gluten cross-contact.
Avenin vs. gluten: understanding oat proteins
- Oats contain a protein called avenin, which resembles gluten structurally but is biologically different.
- Most people with coeliac disease or gluten intolerance tolerate avenin just fine.
However, a small fraction of coeliacs (estimated 1-5%) may react to avenin; this is why you should be aware of individual tolerances while introducing oats.
So, while oats are gluten free foods in a botanical sense, eating oats may require dietary caution because avenin is a potential risk in rare cases.
How oats can get cross-contaminated during processing
- The real risk is not oats, but how they are processed.
- Oats are often grown, harvested, and packaged using the same equipment as wheat or barley.
- Cross contamination occurs and makes a naturally gluten free grain potentially risky for someone with gluten sensitivity.
To be safe:
- Take "Certified Gluten Free" oats, which means they were tested to meet gluten free standards (usually < 20 ppm gluten).
- Look for oats from companies which had dedicated gluten free facilities to eliminate trace exposure.
What Oats Are Gluten Free and Safe to Eat?
