Understanding the Gut Microbiome

Digestion

Unsurprisingly, the gut microbiome plays a significant role in the digestive process. Many of the bacteria in our intestines possess enzymes that human cells lack, but which are essential for breaking down complex carbohydrates, fibres, and proteins. Through fermentation, these bacteria produce short-chain fatty acids which supply energy for the body and help maintain the health of the intestinal lining. This process not only aids nutrient absorption but also supports gut motility, preventing constipation. Gut bacteria also synthesise essential vitamins, such as vitamin K and certain B vitamins, which are needed for crucial metabolic processes. Poor gut health leads to poor absorption of key nutrients.

Immunity

A significant part of the body's immune system is found in the gut. Beneficial microbes help train the immune system to distinguish between harmless and harmful pathogens, support the development of immune cells, and enhance the body's defence mechanisms.

Mood

The gut and brain communicate through what's known as the gut-brain axis. Gut bacteria produce neurotransmitters such as serotonin, which regulate mood. A healthy microbiome contributes to mental wellbeing, while dysbiosis is linked to mood disorders including anxiety and depression and can influence how we handle stress and our overall mood.

Hormones

The gut microbiome plays a role in metabolising and regulating hormones, which is particularly important for women experiencing hormonal changes during their 30s to 50s. An imbalance in the gut bacteria that helps to metabolise oestrogen, for example, can affect weight, mood, and reproductive health.

So now you know how important the gut microbiome is, how can you give yours the best chance of thriving?

Nourishing a Healthy Gut Microbiome

Here are a few tips to help your gut microbiome to flourish:

1. Diverse and Fibre-Rich Diet: Eat a variety of fruits, vegetables, whole grains, and legumes. These foods provide prebiotics; non-digestible fibres that feed beneficial gut bacteria. Aim for a minimum of 30 different plants a week, as this is shown to give the most health benefits.

2. Incorporate Fermented Foods: Foods like yogurt, kefir, sauerkraut, and kimchi contain probiotics, which are live beneficial bacteria that can enhance gut health. If you don’t already eat fermented foods, start slowly and gradually build up your consumption.

3. Limit Processed Foods and Sugars: Processed foods and sugars can kill friendly gut bacteria leaving room for harmful strains to grow.

4. Stay Hydrated: drinking enough water supports digestion and the mucosal lining of the intestines, promoting a healthy environment for gut bacteria.

5. Manage Stress: Chronic stress can negatively impact the gut microbiome. Try to find ways to manage stress such as mindfulness, meditation, or yoga.

6. Only Take Antibiotics When Absolutely Necessary: Antibiotics save lives, but their overuse is widespread. Antibiotics can disrupt the gut microbiome, and overuse is linked with an increased risk of developing Inflammatory Bowel Disease and other gut disorders.

7. Regular Physical Activity: Move more! Regular exercise makes you feel better and has been shown to promote a diverse and healthy gut microbiome.

By adopting a diet and lifestyle that supports gut health, you can improve your overall wellbeing and reduce the risk of chronic diseases.

A healthy, diverse gut microbiome plays a key role in many aspects of our health, influencing digestion, immunity, mood, hormones, and overall wellbeing.

The root cause of most of the chronic illnesses prevalent in society today can be traced back to gut dysbiosis, so it’s worth taking care of your microbes.
