As anyone who’s ever had a bloated or sore tummy will know, when your gut health is out of whack, it can throw off your whole life.
How to tell if your gut is healthy
Our tummies are pretty good at letting us know if something isn’t right. The odd boat of tummy trouble isn’t a big deal (although it can be miserable!) but if you experience regular diarrhoea, reflux, pain, bloating, constipation or any form of upset stomach, then you may need to address your gut health.
Signs of an unhealthy gut
Other symptoms can include bad smelling poo, loose stools, feeling gassy, a foggy head or a bad mood – roughly 80% of serotonin is made in the gut. Some experts have suggested that craving foods, especially sweets and sugar, can imply that your gut bacteria are out of whack. This can happen when there’s an overgrowth of yeast in your gut, which can cause sugar cravings.
What is a gut feeling?
We’ve all heard the expression ‘go with your gut’ and it turns out there may be some truth to it. Being led by your stomach might make sense, according to Linda Rinaman, the author of a review on the biology of gut reactions for Florida State University. [https://news.fsu.edu/news/2018/03/20/gut-feelings-red-flag-according-new-fsu-research/] Her research has found that our gut-to-brain signals are a powerful influence on our feelings, mood and even our decision making skills. She says that the gut and brain ‘talk’ to one another via the vagus nerve, and that the gastrointestinal tract sends more signals to the brain than any other organ.
Gut health and diet
How does eating fat affect gut health?
Eating too much saturated fat can cause an inflammatory response in the GI tract, which, according to Linda Rinaman, can make you feel anxious or even depressed.
A good gut diet
As is so often the case in health, when it comes to pleasing your tummy bacteria, plant-based is best. Different microbes in the stomach prefer different foods, so aim to eat a wide range of fruit and vegetables. Avoid processed foods where possible, and choose extra-virgin olive oil over other fats – it’s packed with polyphenols that gut microbes love.
Fibre for gut health
Another reason primarily plant-based diets can work wonders for the stomach is the high levels of fibre (or fiber as the Americans know it) in whole fruits, vegetables, pulses and nuts. Add in some wholegrains too. But be careful, adding too much fibre suddenly can cause bloating, so start off with gradual changes and plenty of water.
How can I improve my gut health?
As well as changing what you eat, you can also reduce the amount of alcohol you drink and give your water intake a boost. Stress is often a cause of tummy pain, so consider treating yourself to a massage, trying some meditation or addressing other causes of stress in your life.
Of course if symptoms persist it’s worth speaking to your GP to rule out intolerances or more worrying problems.
Are antibiotics bad for your gut?
Antibiotics are of course brilliant for solving a myriad of infections, but the downside is that they sometimes wipe out protective gut bacteria as well – sometimes causing diarrhoea. A further, more severe risk, is that you could potentially develop a Clostridium difficile (C. difficile) infection. This is a dangerous type of bacteria that can cause life-threatening complications.
The good news is that your likelihood of contracting it is lowered if you take probiotics during your course of antibiotics.

What’s the difference between probiotics and prebiotics?
Probiotics are foods or supplements that have live bacteria in them, and are thought to benefit the gut. Prebiotics are foods that help boost existing gut bacteria and encourage a diverse culture of microbes. They include things like veggies and wholegrains.

Leaky gut syndrome
Leaky gut syndrome is also sometimes referred to as intestinal permeability, although there is some debate in the medical world about what it is, and the problems it causes. The problem comes when the mucosal barrier in the bowel becomes less effective. Many experts believe it can lead to conditions including MS and chronic fatigue syndrome.

How a healthy gut can help cancer treatment
The research tested the microbiome (the collection of microscopic species in the gut) in cancer patients, and found that specific species as well as overall diversity had an impact on the effectiveness of immunotherapy drugs.
The microbiome works for digestion, to protect the body from infection and to regulate the immune system.
One study found that patients who had taken antibiotics (thought to damage the microbiome) were more likely to see tumours grow while going through immunotherapy.
Those that responded well to therapy tended to have a more diverse microbiome.
