Digestive discomfort and food-related sensitivities can make it challenging to feel your best, especially when certain ingredients trigger unwanted symptoms. Finding the right balance of nutrition and lifestyle habits is key to maintaining comfort and overall well-being. As awareness continues to grow, many individuals are seeking gluten intolerance support to help manage symptoms, support digestion, and improve quality of life. In this article, we'll explore practical strategies to help you feel more balanced and in control.
What is Gluten?
Gluten is the combination of two proteins, gliadin and glutenin, which exist in varying amounts in the endosperm (the inside) of most grass-related grains, such as wheat and rye. These proteins give dough its elasticity, allow leavening, and keep baked goods chewy and cohesive.
What Is Gluten Intolerance?
Gluten intolerance varies in severity, from mild to a severe intolerance, called Celiac’s disease. Symptoms include diarrhea, bloating, cramping, abdominal pain and vomiting 1-3 hours after consumption of gluten-containing foods.
Gluten is considered a complex protein, meaning it contains two or more chains of individual proteins. It is a large molecule, one of the reasons that it is difficult for our digestive systems to handle. When gluten molecules reach the small intestine, they can actually cause small holes in the mucosal lining, creating something called Leaky gut syndrome. Normally, the lining of your gut selectively filters through the contents of the intestine, absorbing the nutrients we need and allows everything else to pass through to be eliminated as waste. When the gut lining is compromised, foreign particles are able to pass through and into the bloodstream. This causes the immune system to get involved, as it sets out to attack these foreign materials. The intestinal damage causes malnutrition and deficient absorption of nutrients and fat.
Symptoms such as rash, anemia, weight loss, steatorrhea (smelly and shiny stool), bone pain and osteoporosis, frequent colds, mood swings, and a host of others are all due to a lack of nutrients.
What Foods Contain Gluten?
Gluten is also an additive and acts as a stabilizing agent in products where it is unexpected, such as ice cream and ketchup. It is these products that can make gluten-free diets so challenging for those who suffer from intolerances. Gluten-containing foods are as follows:
- Barley, oats, rye, wheat, spelt, and gamut
- Hydrolyzed & Texturized vegetable proteins
- Hydrolyzed plant protein malt
- Modified food starch
- Some soy sauces
- Grain vinegars, white vinegar, and bouillon cubes
- Binders, fillers & some natural flavours
- Hot dogs and luncheon meat
- Beer
- Gravies, mustard, ketchup, and bottled salad dressing
- Non-dairy creamer
- Processed foods, chocolate
- Curry powder and seasonings
Be cautious with oats. Although there are now many brands that certify their oats as gluten-free, many other companies transport, prepare and package their oats alongside many gluten-containing grains. Cross-contamination is very common.
What Are Symptoms of Gluten Intolerance?
Gluten intolerance symptoms can occur in infancy, but depending on the severity, sometimes they do not present until adulthood. This is a genetically inherited disorder – infants can have a failure to thrive as a symptom. When gluten intolerance presents in adulthood, it is often triggered by some kind of stressor (emotional, mental or physical). Symptoms will stop once the gut lining is healed through the removal of gluten-containing foods from the diet. There are some people who can reintroduce small amounts of gluten into their bodies without adverse side effects, but many remain on a gluten-free diet for their entire lives.
Gluten Intolerance Support Tips
Individuals with gluten intolerance are advised to eat a healthy diet, including fruits and vegetables, lean protein such as fish and poultry, healthy fats and gluten free grains, including rice, corn, millet, quinoa, potato and soy. The following list of supplements can be used for preventing and repairing damage from gluten intolerance.




Thanks for good info. Amazing where you find gluten...some foods you show here in this article I was unaware of.
Hi Margaret,

I've been suffering from a Gluten intolerance for years now, but I find that I'm finding more and more foods that have gluten in them and I cant eat. So sad. Last time at my Naturopathic doctor has recommended I try a NewRoot Intestinew product. And that has been helping me a lot. I find I still cant have what I used to but at least I'm not in any more pain from day to day trying new products that I would not even think of having gluten. I hope this article helped with some of the questions you had unanswered.
Hello Uliana,
Thank you for sharing. Gluten is slipped into a lot of foods that you wouldn't think would have gluten, it's a tough intolerance to navigate. We are glad our article helped you and that the New Roots supplement recommended by your doctor has provided relief as well. If you have any future questions or concerns, please reach out, we are always here to help.
Stay healthy & well!
In my opinion, it's not really a problem with gluten but the way food is grown nowadays. I believe GMO's and other chemicals used in farms are creating gluten intolerance which is why we've decided to go organic and support digestion as much as possible to heal the gut.
Hello Hassan,
Thank you for your comment, we think you'd also enjoy our video on GMO's as well, check it out here:

Gluten intolerance and celiac disease are different. People with celiac disease have an autoimmune response to gluten. This means their bodies try to fight against gluten as if it were a virus. This reaction causes inflammation and damage to their digestive tracts. Celiac disease is the result of an abnormal gene. People with celiac disease also have high levels of certain antibodies in their blood, which are substances that fight gluten.
Gluten sensitivity and celiac disease cause a lot of the same symptoms. But people with gluten sensitivity don’t have an abnormal gene or antibodies in their blood.
Hello Paul,
Thank you for enjoying our articles. You are correct, they are different and may need different support for each. You can read more on Celiac here:

I have recently been going through diagnostics with specialist after specialist. Scary deep dives on the internet is NOT helpful. Thanks for your simple explanation and thoughts on the subject.
Hello Leanne,

I did not know that gluten intolerance can be a specific health condition in infants, and that in infants, gluten intolerance can result failure to thrive. Also, it is incredible that an estimated 15% of the population may be gluten intolerant!!: it would be really interesting to see the exact source of this statistic/how intolerance was defined in determining this percent. Finally, your note about gluten cross contamination is a really good one: I knew this but it can be tricky for people. Cross contamination is a very common issue and it is unfortunate that people who have very poor tolerance for gluten may have to pay for more expensive, certified gluten free versions of foods. Overall, very useful article and thank you for another great resource, NN! :)
Hello Rachel,
We're excited you could discover more about gluten intolerance, it seems to be an increasing health concern today. Indeed, those with a high gluten sensitivity have to watch for gluten cross-contamination and unfortunately specialty foods do tend to be more costly. We're glad you enjoyed this read and think you'll also enjoy learning about another increasing intolerance, lactose: https://www.nationalnutrition.ca/articles/health-concerns/lactose-intolerance/
I don't seem to have this problem myself but my mother does. I never liked a lot of bloating foods, I avoid them, especially at night, but sometimes I eat them anyways due to weakness. I've noticed it has become a popular thing to avoid gluten, it's all over the restaurants but it wasn't always like that. I am glad these articles are here so I can share them with my mother who would otherwise be left in the dark over her lack of nutrients in her diet. It's so important to get nutrients to avoid issues that affect so many millions of people.
Hello Kaveh,
Gluten intolerance is uncomfortable and frustrating because it's in so many foods and sauces. We hope you can find some gluten free recipes she would like from our recipe section: https://www.nationalnutrition.ca/articles/healthy-recipes/
Being gluten intolerant I do my best to be cautious but sometimes the struggle is real. You honestly don't realize all the products that do have gluten in them until you start getting symptoms and try to scale back to feel better again. Mind blowing how this is such a huge impact for so many. Thanks for the informative information as there is always something new to learn for sure
Wow-as you mention, wheat, barley, rye, AND OATS!!! Even not oats are not necessarily gluten free. That must be a tough condition to deal with. Though, I do think that it almost becomes an "explain-away" for other issues and allergies, gluten intolerance, that is. It does make sense, that said, that in today's food environment, this kind of a thing is more and more of an issue. It is great to illustrate the point you are making about gluten being everywhere with that giant list of foods. That is something to appreciate (and think about!!)
