Bacteria eat gut lining with the lack of dietary fibre

Diets low in fibre are commonly used with patients to address digestive symptoms but detrimental to your gut lining if adhered to for too long. Commensal bacteria, when deprived of fibre as a fuel source can use host secreted mucous glycoproteins instead. This can lead to erosion of the colonic mucous barrier.

Glycoproteins make up mucous secreted in the intestines with 80% being carbohydrates. Commensal bacteria (when one organism derives food or benefits from another without hurting or helping it), use this as an energy source. The mucous lining limits the penetration of bacteria whilst producing an antimicrobial substance that kills or inhibits the growth of bacteria close to the lining.

When fibre is not available the microbes use this rich mucous layer as a fuel source and hence negatively affecting the mucous barrier of the gut, which can lead to inflammation and increased susceptibility to pathogens.

Numerous mouse studies conclude heightened expressions of inflammatory markers leading to various digestive and bowel issues.

Fibrous foods to introduce or increase in your diet could include – pears, strawberries, avocado, apples, raspberries, bananas, carrots, beetroot, broccoli, Brussel sprouts, lentils, split peas, chickpeas, quinoa, oats, popcorn, almonds, chia seeds, sweet potato and my fav dark chocolate.

Fibre is an important nutrient that may promote weight loss (the right type of fibre), lower blood sugar levels and assist constipation.

If you need any further advice with fibre in your diet book in for a naturopathic appointment.
