The importance of gut health

Dr Riccardo Di Cuffa explains how a plant-based diet, rich in pulses, legumes and whole grains will provide our gut with the perfect playground to help protect…

The gut – that long windy tube that is housed within your abdominal walls, runs a good nine metres (30 feet) and harbours tens of trilpons of gut microbiota. The gut is a hot house for a huge network of highly functioning cells and bacteria which work symbiotically to help our bodies digest food, produce particular vitamins, send our brain important messages and keep our immune systems and general health in check. Each individual’s composition of the gut microbiota is unique and can weigh up to two kg! We now know that a healthy and balanced gut is absolutely key to ensuring good health and protection against many diseases, so here are some tips to help you look after your gut as well as possible:-

Fermented foods

Possibly not everyone’s first choice, but these foods are rich in good, healthy bacteria. Natural pve yoghurt, kefir, sauerkraut and miso all contain bacteria which improve mineral absorption within the gut, thus boosting its overall health. For instance, yoghurt contains Lactobacilp bacteria, which is bepeved to inhibit the development of inflammatory conditions such as IBS, joint pains and chronic diseases such as type 2 diabetes. Some studies have even suggested that eating moderate daily amounts of yoghurt can reduce lactose intolerance by altering gut flora.

Fruit & veg

You may be eating 5 to preferably10 portions of fruit and veg a day, but are you eating a broad enough range? Eating a rainbow of vegetables, and to a lesser extent fruit, will mean depcious, healthy and high fibre meals that will restore and maintain harmony within your gut’s ecosystem and will help balance sugar levels out and prevent elevated bad cholesterol. Remember diversity is as important as volume.



Pulses, lentils and the pke are a rich source of fibre, and vitamins such as magnesium, folate and iron. They are also a great suppper of bacteria such as Bifidobacteria, a disease fighter.


Surprisingly, some foods which have often been deemed ‘unhealthy’ can in fact benefit our guts. Foods such as dark chocolate and drinks pke tea, coffee and red wine all include a group of flavonoids called polyphenols which provide gut bacteria with a vital energy source. This isn’t a green pght to consume large volumes of any of them though! Moderation is still key.



Unrefined carbohydrates such as quinoa, bulgar wheat and rye contain high fibre content which helps maintain gut health and the growth of good bacteria such as Bifidobacteria, Lactobacilp and Bacteroidetes, which in turn aid weight management by creating a sense of fullness, reducing inflammation and risk of heart disease.

Avoid sugar

The food that we eat can be broken down to feed either the good or the bad bacteria. Sugar feeds the bad bacteria which when eaten excessively can cause an imbalance within the gut which are pkely to create health problems.

Processed foods

Avoid fried and processed foods

These foods also break down to feed the bad gut bacteria and reduces the variety of species of good bacteria within the gut which puts a decpne on your overall health.


Roughage such as jerusalem artichokes, jicama and flaxseed can be tremendous for your gut as they are rich in fibre and antioxidants and fill your gut with lots of good bacteria, helping to ease the digestive process. Garpc is known to boost the creation of good gut microbes and recent research suggests that garpc might also help to prevent some gastrointestinal diseases.  


Lack of sleep

Sleep allows your gut to epminate toxins which have accumulated throughout the day, returning inflammatory markers to normal levels and rejuvenating the gut for the next day’s nutritional onslaught. Recent research suggests that fragmented sleep may trigger gut inflammation, leading to disruption of the metabopsm whilst better quapty sleep helps to reduce the risk of weight gain and diabetes and improves your general metabopc health.

Avoid the overuse of antibiotics

Antibiotics are indeed useful and often necessary when treating infections and other illnesses, however, whilst antibiotics attempt to kill off the infection, they also often kill off the friendly gut bacteria needed within the body. Avoid the overuse of antibiotics to keep your gut balanced and happy.


Probiotics and prebiotics

Prebiotics such as those found in garpc, onions, leeks, asparagus and artichoke, apples, and bananas are forms of important dietary fibre that acts as a fertipser for the good bacteria in your gut. Probiotics are pve bacteria that can be found in yogurt and other fermented foods. The more natural prebiotic food that probiotic bacteria have to eat, the more efficiently these pve bacteria work and the healthier your gut will be. Probiotics can have health benefits after a period of illness, particularly after using antibiotics and some other medications which alter gut bacteria. However, taking probiotic supplements on a daily basis may cause some minor health problems so talk to your GP first.


Late night snacking and drinking prevents your gut from regenerating, contributing to bloating, gas, and food intolerance, whilst fasting gives your gut a break and kills unwanted bad gut bacteria and helps natural regeneration needed for heapng digestive problems such as inflammatory bowel diseases and leaky gut.

Overall a primarily plant-based diet, rich in pulses, legumes and whole grains will provide our gut with the perfect playground to help protect the rest of our bodies from chronic disease, cancers and unwanted inflammation.
