Gut instincts

With rising interest in digestive health, consumers are becoming increasingly aware of the importance of maintaining a healthy gut, reports Charlee Singleton.

In recent years, the term ‘gut health’ has transcended the medical world to become a buzzword in the wellness industry. The shift isn’t without merit; emerging research consistently underscores the importance of a healthy gut in maintaining our well-being, with more than 50,000 papers published on the gut microbiome in the last ten years alone. And the general public are taking note, as Holland and Barrett’s recent Gut Health Report found that monthly searches for ‘gut health’ in the UK have increased by 23% year on year, averaging 23,000 searches per month.

The gut, often referred to as the body’s ‘second brain,’ plays a pivotal role in various bodily functions beyond digestion.  Everything from mental health to our immune system is influenced by the gut, and yet, amidst the hustle and bustle of modern life the well-being of our gut often takes a backseat, leading to multiple health issues.

“Looking after your gut health means looking after your overall health, gut microbes do things the gut can’t do.”

The Gut Microbiome: A Complex Ecosystem

At the heart of gut health lies the gut microbiome, a complex collection of trillions of microorganisms, including bacteria, viruses, and fungi that reside in your gut – primarily in the large intestine. These microorganisms are uniquely influenced by your specific diet and lifestyle choices, and actively contribute to your physical and mental health.

“Your gut microbiome has the power to communicate and influence the health of other organs in the body, including the brain, skin, liver and heart. So looking after your gut health means looking after your overall health,” says Dr Sammie Gill, Symprove’s specialist gastroenterology dietician.

“Gut microbes do things the gut can’t do. For example, they break down all of the non-digestible nutrients (such as fibre and plant compounds). In exchange, they release beneficial compounds that get absorbed into the bloodstream and have downstream effects on other organs of the body.

“Your gut microbes are also mentors to your immune system (of which 70% sits along your gut), influencing how it behaves. In fact, they support the immune system to develop by teaching and training it to react appropriately. Some gut microbes are able to produce vitamins, such as vitamin K and some B vitamins.”

Inside Gut Influences

Whilst several factors influence the functionality of the gut microbiome, diet plays the most significant role and is thought to account for up to 60% of the influence on your digestive health. A diverse and balanced diet supports a healthy microbiome. Foods high in fibre, such as whole grains, legumes, fruits, and vegetables, serve as prebiotics, which feed beneficial bacteria, whilst fermented foods like yogurt, kefir, sauerkraut, and kimchi introduce probiotics—live beneficial bacteria—into the gut.

“While both prebiotics and probiotics support gut health, they work in different ways when they reach the gut,” explains Gill. “Prebiotics are mainly types of fermentable fibre that act as ‘food’ for your resident gut microbes to feast on. On the other hand, probiotics are live microbes that you’re ‘adding in’ – they prompt favourable health effects as they move through your gut.”

UK adults should be aiming for 30g of fibre a day, but most are getting less than 20g – mainly due to the modern diet which is high in saturated fat, sugar and consists largely of processed foods. These diets not only limit the amount of fibre but can also disrupt the microbial balance leading to a variety of health issues.

But its not just about food. “There are so many other factors that can influence the health of your gut beyond what you eat,” Gill adds. “For example, your mental state (e.g. how stressed you feel), how much physical activity you do, whether you’re taking unnecessary medications, whether you have a pet, whether you’re managing to get a good night’s sleep, whether you have a health condition, whether you smoke or drink in excess.”

So lifestyle factors can also influence gut health, but the reverse is also true. A disruption in the gut microbiome can cause sleep disruption, which in turn can promote metabolic dysfunction. Beneficial bacteria can aid in the creation of hormones such as serotonin and melatonin, which are important for our sleep/wake cycles. While antibiotics are crucial for treating bacterial infections, they can also indiscriminately kill beneficial bacteria, leading to dysbiosis.

“Nurture your gut microbiome well with the right things and it will reward you. If you don’t, it can start to suffer which can have implications for health later down the line.”

Dodging Dysbiosis

Dysbiosis, an imbalance in gut bacteria, has been linked to several health issues including chronic fatigue and chronic inflammation, along with an increased susceptibility to infections. Recent research also shows links between the microbiome and risks of cardiovascular disease, inflammatory bowel disease and type 2 diabetes, as well as mental health issues such as depression and anxiety.

The most common signs of poor gut health include digestive issues like persistent bloating, gas, constipation, diarrhoea and heartburn, however the symptoms of an unhealthy gut can be far and wide. Poor sleep, low energy levels, frequent infections, and skin conditions such as eczema and acne have all been linked to imbalances in the gut microbiome.

Mood disorders such as anxiety and depression can be exacerbated by an unhealthy gut due to the gut-brain connection – The Cost of Constipation Report, 2020 from Bowel Interest Group found that 40% of patients with constipation experience anxiety disorder; 38% experience depression; and 68% reported that constipation affects their performance at work or at school. Chronic stress can also alter gut sensitivity and increase intestinal permeability, often referred to as “leaky gut syndrome.” This condition allows harmful substances to enter the bloodstream, potentially triggering inflammation.

“Nurture your gut microbiome well with the right things and it will reward you. If you don’t, it can start to suffer which can have implications for health later down the line. Looking after your gut health means looking after your overall health,” says Gill.

“Focus on plants (fruit, veggies, beans, legumes, nuts, seeds, wholegrains, herbs, spices). They are packed with different types of fibre and health-promoting phytochemicals (i.e. plant chemicals like polyphenols).

“In fact, a study at the University of Bergen in Norway found that a diet rich in plant-based foods (such as beans, wholegrains, and nuts) can add up to a decade to your life.

“Data from the American Gut Project showed that people who ate at least 30 different plant-based foods per week had a more diverse gut microbiome than those who ate fewer than 10 different plant-based foods per week.

“Each community of microbes in your gut have different ‘preferences’ so keep them well fed and nourish them with a variety of plant-based foods.

“Other ways to support gut health? Get outside, keep active, prioritise sleep, and manage stress.”
