What is gut health?

Thanks to recent research, we now know that our gut health has a wide impact on our body and overall wellbeing. Inside our gut (large intestine), we have trillions of tiny living organisms, including bacteria and other microbes. These organisms help support many important body functions. 

Together, these are known as the gut microbiota (or the gut microbiome), and each person’s is unique to them.

There are lots of factors which impact what your gut microbiome is made up of. Some we have influence over, and some are out of our control:

• Whether you were breastfed as a baby
• Medications like antibiotics
• Dietary habits
• Our environment
• Genetics
• Ageing 
• How you were born

These factors help shape your gut over time, which is why everyone’s gut health looks slightly different.

Why it matters

There’s no single “perfect” gut microbiome. What matters most is the balance and variety of bacteria in your gut. 

These gut microbes have many roles:

• Help with digestion – they feed on fibre and help break it down
• Support your immune system
• Help produce certain vitamins
• Produce beneficial compounds called short-chain fatty acids
• May play a role in mental health
• May be linked to some health conditions, including obesity and heart disease, but more research is needed

The role of probiotics

Probiotics are live bacteria. They can be found in foods like yoghurt or taken as supplements. 

There is some evidence that they may help restore the natural balance of bacteria in the gut when it has been disrupted, for example after antibiotics or illness. 

However, there is currently limited evidence to support many of the wider health claims made about probiotics.

For most people, probiotics are not needed for good gut health.

They are generally safe, but you should speak with your clinician if you have any questions about whether they are right for you.

Simple ways to support gut health

Gut health is shaped by your overall diet and lifestyle, not one specific food or supplement. There are some simple, evidence-based ways you can support your gut health: 

• Eat a varied diet - include a wide range of plant foods such as fruit, vegetables, legumes, nuts, seeds, herbs, spices and whole grains
• Eat more fibre - this is the main food for your gut bacteria
• Try fermented foods - such as yoghurt, kefir, kimchi or sauerkraut
• Stop smoking, if you do smoke
• Prioritise good sleep

Summary

Gut health is about the balance and variety of bacteria in your digestive system, and it plays an important role in your overall health.

You don’t need to follow extreme diets or rely on supplements to support your gut.

Focusing on simple habits, like eating a varied, fibre-rich diet and looking after your overall lifestyle, can make a meaningful difference over time.
