Your gut, often called the ‘second brain’, plays a crucial role in your overall health. It’s not just about digestion; your gut affects your immune system, mental health and even chronic diseases.

Good gut health

What is gut health?

Gut health refers to the balance of microorganisms that live in your digestive tract. These bacteria, fungi and viruses are collectively known as the gut microbiota, and the genetic material they contain is called the gut microbiome. Having a diverse range of these microorganisms is key to a healthy gut, as they support digestion, boost immune function and contribute to overall wellbeing.

Why gut health matters

Digestive health: A balanced gut microbiota aids the digestion and absorption of nutrients.
Immune system: Around 70% of your immune system resides in your gut, making it a critical player in fighting off infections.
Mental health: The gut-brain connection refers to the communication between your gut and brain. If you’ve ever experienced ‘butterflies in your stomach’ or had a ‘gut feeling,’ you’ve experienced this interaction. An imbalance in gut bacteria can influence your mood and mental health.
Chronic diseases: Poor gut health has been linked to chronic diseases such as diabetes, heart disease and cancer.

Signs of an unhealthy gut

Digestive issues like bloating, gas and diarrhoea
Unexplained weight changes
Sleep disturbances and chronic fatigue
Skin irritation caused by the body’s inflammatory response
Getting sick often caused by an unhealthy immune system

How to improve gut health

Eat a diverse range of foods: A varied diet rich in wholefoods supports a healthy gut microbiome.
Consume fermented foods: Foods like yoghurt, kimchi and sauerkraut are rich in probiotics that boost gut health.
Stay hydrated: Drinking plenty of water supports the mucosal lining of the intestines and the balance of good bacteria.
Limit antibiotic use: Overuse of antibiotics can disrupt the balance of gut bacteria.
Manage stress: Chronic stress can disrupt the balance of your gut microbiome.

Foods that promote gut health

Fibre-rich foods: Fruits, vegetables, whole grains and legumes
Fermented foods: Yoghurt, kefir, kimchi, sauerkraut and kombucha
Prebiotic foods: Garlic, onions, bananas and asparagus
Healthy fats: Omega-3-rich foods like salmon, chia seeds and flaxseeds

Speak to your community pharmacist

Maintaining a healthy gut is essential for your overall wellbeing. By making mindful choices about your diet and lifestyle, you can support your gut health and, in turn, enhance your quality of life. If you have persistent gut issues, speak with your community pharmacist. They can offer personalised advice about diet and lifestyle choices to promote a healthy gut or refer you to a GP if they think your situation requires further medical attention.
