What is Leaky Gut?



Also known as an increased intestinal permeability


We have an extensive intestinal lining in our bellies that covers more than 4000 square feet of surface area. When this barrier is working correctly, it can control what is absorbed into the bloodstream (nutrients) and what is rejected (pathogen, viruses, toxins)


Leaky gut, or increased intestinal permeability (IP), is a condition that creates gaps in this lining which then allows food particles, bacteria, and waste products to cross the barrier directly into the bloodstream. This might be what is responsible for any food allergies or intolerances you might be experiencing.

Top tips to prevent a leaky gut:


Reduce stress: it has been shown that stress impacts intestinal permeability by increasing the gaps between cells. Look at different ways to reduce the stress in the body, which could help improve sleep and prevent leaky gut.



Use Probiotics: especially lactobacillus, which has been shown to decrease bacterial overgrowth if present and restore the intestinal barrier. Also, probiotic intervention may help reduce stress and act as an antidepressant.


Limit alcohol and antibiotics: Both can be harmful to the barrier of the gut, so it would be recommended to limit them as much as possible

Vitamin D has been found to protect the intestines, so make sure you have a good level of vitamin D all the year


Glutamine and curcumin:


Both of these nutrients are very helpful with healing a damaged gut lining and can reduce inflammation and stress in the gut.


Food richer in glutamine :

  • Chicken

  • Fish

  • Cabbage

  • Spinach

  • Dairy

  • Tofu

  • Lentils

  • Beans


Elimination diet: this is a method where all allergen foods are removed from the diet, which could also irritate the gut.


Intermittent fasting: is a method where you can eat only during an eating window cycle which gives more time for the body to heal and detox. In addition, it could reduce caloric intake, which has been shown to help heal the leaky gut and give the body the time to rest.
