Leaky Gut Explained

Jul 22, 2021 | Nutritional Information

What is leaky gut?

 Our intestinal tract is lined with specialized cells that can facilitate the absorption of nutrients while also act as a barrier against potentially harmful substances from passing through the digestive tract such as toxins, microorganisms, and other antigens (allergy or immunity triggers). In healthy intestinal tracts, these specialized cells form tight junctions between themselves to allow for this selective permeability (allow things to pass through). When exposed to certain environmental triggers, the junction between the cells is affected and forms openings that allow larger particles to travel through the intestinal lining and into the bloodstream. This phenomenon is commonly referred to as “leaky gut.” When the gut is “leaky” and bacteria and toxins enter the bloodstream, it can cause widespread inflammation and possibly trigger a reaction from the immune system causing a multitude of health issues from autoimmune disorders to brain fog and skin issues. 

 What are some symptoms of leaky gut?

-Cognitive issues, such as memory problems or brain fog

-Digestive issues, such as chronic diarrhea or constipation




-Joint pain, inflammation

-Multiple food sensitivities

-Nutrient malabsorption and resulting deficiencies

-Skin conditions, such as acne vulgaris


What can cause leaky gut?

-Chronic antibiotic use

-Prescription medications (ex. NSAIDs, immunosuppressants)

-Chronic or excessive stress

-Excessive alcohol consumption

-Exposure to environmental toxins (pesticides, herbicides)

-Gluten, a protein found in certain grains like wheat

-Viral infections

-Nutrient deficiencies 

-Poor diet (low in fibre, high in saturated fats and carbohydrates)

-Bacterial imbalance (dysbiosis)

Conditions associated with leaky gut:

Twenty-five hundred years ago, Hippocrates stated that “All disease begins in the gut” and he was right. According to current research studies, leaky gut is responsible for a multitude of conditions including:

-Rheumatoid Arthritis

-Irritable Bowel Disease (Crohn’s, IBS)


-Multiple Sclerosis





-acne, skin irritations/rashes

So what can we do help heal the gut?

In holistic healing, the 4R’s approach, listed below, is used to help heal the gut lining 

Remove: where pathogens and inflammatory triggers are removed from the diet.



-food sensitivities such as dairy

-trans and saturated fats

-refined sugar 

-food additives/preservatives

-foods high in sulphites (cured meats)


Replace:  where essential nutrients that support digestive health are added to the diet 

-fibre from fruits and vegetables or if you don’t eat enough foods that contain fibre, a good supplement is a great alternative. Ultimate Fibre Plus Powder 

-omega-3 fatty acids (flax, salmon, herring) 


-organic fresh produce, fruits, and vegetables

-anti-inflammatory herbs/ spices like curcumin and garlic

Reinoculate:  where beneficial bacteria are introduced through probiotic supplements and diet 


-fermented foods such as tempeh, miso, sauerkraut, kimchi

-cultured dairy such as kefir, Greek yogurt 


Repair:  where certain nutrients are used to help promote healing of the gut 

-zinc: helps to strengthen the gut lining 

-l-glutamine: L-Glutamine is an amino acid essential for the health of the immune system and digestive tract. In the gut, it promotes the health and function of the mucosal cells for healing and repair



-Fibre: Ultimate Fibre Plus Powder by Alpha Science Laboratories

Omega Fatty Acids: Super EFA Forte Capsules + D by Genestra

Mushrooms: Mushroom Complex SAP by Pure Encapsulations

Probiotics: HMF Forte by Genestra

Zinc: Zinc Supreme by Designs for Health
