The human gut, often thought of simply as the organ responsible for digesting food, is so much more than that. In fact, up to 70% of our immune system resides in the gut. This means it’s fundamental to maintaining a healthy body and preventing disease.

Research has shown that the health of your gut may be linked to conditions such as obesity and diabetes, autoimmune diseases, mental health issues and even cancer.

Poor gut health is a condition that affects many people in various ways. Common causes of poor gut health include dietary choices, environmental factors, and lifestyle habits. Eating foods with high levels of processed sugar, saturated fats, and additives can cause an imbalance in the digestive system. Furthermore, exposure to toxins from the environment or certain medications can also damage the balance of beneficial bacteria in the digestive tract.

In addition to these external triggers for poor gut health, lifestyle habits such as stress and lack of sleep can also have a negative effect on digestive function. Stressful situations activate the body’s fight-or-flight response which can disrupt digestion and weaken immunity. Similarly, not getting enough sleep on a regular basis impairs cognitive functioning which has been linked to issues with digestion and metabolism.

Processed foods are now a staple in the Western diet, but consuming too much can have detrimental effects on our gut health. Studies indicate that regular consumption of processed foods leads to an increase in gastrointestinal disturbances and decreased nutrient absorption.

Processed foods lack fibre and prebiotics, which are essential for maintaining a healthy microbiome. In addition, many processed meals contain additives like preservatives, artificial sweeteners, and food dyes which cause inflammation in the gut leading to leaky gut syndrome.

This type of disorder has been linked to numerous chronic diseases such as autoimmune disorders and digestive issues. Eating processed food also hinders our body’s ability to absorb key vitamins and minerals from other healthy sources such as fruits and vegetables due to the presence of chemicals within these products.

Probiotics are beneficial bacteria that live naturally within our intestines; they provide numerous health benefits including supporting immunity and digestion whilst reducing levels of harmful ones like yeast or bad bacteria.

Taking probiotic supplements on a regular basis may also improve mental wellbeing by helping to produce neurotransmitters like serotonin which affect mood regulation. Probiotics should be taken along with prebiotics—food components that act as fuel for beneficial microorganisms—for optimal results.

Probiotics can be taken as a supplement or found naturally in foods such as yoghurt, sauerkraut, kimchi (a personal favourite), miso, kefir, kombucha and tempeh.

Prebiotics are dietary fibres that stimulate the growth of beneficial bacteria in the intestine by providing nourishment to these bacteria. They help strengthen your body’s microbiome, which is vital for proper digestion and nutrient absorption from foods. As prebiotics are not digested by humans, they act as food for ‘good’ bacteria found in the gut, allowing them to colonise and reproduce.

Fibre is also important for healthy digestion; it helps keep your bowels regular while also promoting good bacteria growth. Fibre-rich foods include apples, bananas, raspberries, black beans, lentils and oats.

Stress has become an unavoidable part of life. While it is normal to experience stress in certain situations, like a lifestyle change or career advancement, overly stressful situations can have long-term effects on our gut health. Stressful events can disrupt the delicate balance of microorganisms that live in our digestive systems, leading to a variety of gastrointestinal issues.

Research has shown that stress can influence gut health in multiple ways. For example, when people are stressed they often consume unhealthy foods which can lead to increased inflammation and less beneficial bacteria in the gut.

In addition, chronic stress impairs digestion by decreasing blood flow to the intestines and disrupting communication between the brain and gut known as “the gut-brain axis”. Stress also alters immunity which makes us more susceptible to infection from harmful bacteria and yeast overgrowth.

Exercise is essential for improved gut health. Consistency and regularity are key when it comes to exercising for better gut health, even if it’s just a minimal amount. When engaging in physical activity, walking or light jogging is an ideal way to get started. In addition, incorporating weights can help to strengthen the muscles and ligaments that support the core area of the body which helps improve gastrointestinal functions.

Studies have shown that exercise can be beneficial to digestion by increasing blood flow throughout the body and improving overall metabolic function. Improved blood flow helps carry oxygen and other nutrients more efficiently to digestive organs as well as aiding in muscle relaxation which can alleviate symptoms like cramping, bloating and gas pains. Exercise also increases endorphins that create positive feelings in your brain which can relax the digestive system for better overall function.

Good gut health is essential for overall health, wellness and mental health. Gut health can be improved through healthy nutrition and lifestyle choices. The digestive system plays an important role in maintaining the body’s immune system, which helps ward off disease.

Eating foods that are rich in fibre, such as fruits, vegetables, beans, nuts, and whole grains can help to keep your digestive system functioning properly and reduce inflammation. Avoiding processed foods that contain additives, sugar or unhealthy fats can help support a healthy balance of bacteria in the gut.

Prebiotics and probiotics are two of the most popular supplements used to promote a healthy digestive system. Both have different pathways towards achieving improved gut health.

Lastly, in addition to eating a healthy diet, getting enough exercise and sleep are key components to good gut health. Exercise helps reduce stress hormones that can cause digestive problems like irritable bowel syndrome (IBS). Getting enough restful sleep is also important for digestion since it helps restore balance to hormones that affect appetite and metabolism.
