Your gut ecosystem is as unique as your fingerprint. No one else on earth has one exactly like yours. And here’s the part most people forget: what you eat isn’t just nutrition for you - it also feeds the trillions of bacteria living in your gut. You’re never eating alone.
If you want to improve your digestion, support a healthy weight, or simply feel more vibrant, there are universal principles that help every gut thrive. Discover what is gut health, why is it important, what a healthy gut looks like and signs of poor gut health.
If you decide to dive deeper into your own gut health, getting some blood work done with Marko is a great place to start, or reach out for a personalised consultation and we’ll start the journey together.
Gut health refers to the wellbeing of the entire gastrointestinal (GI) tract - a passage that snakes from your mouth to your anus - and the balance of its microorganisms, collectively known as the gut microbiome. Did you know your GI tract is around 8 meters long, its surface area would cover half a badminton court, and its home to trillions of microorganisms which weigh around 500g?
Your gut is an incredibly complex system which plays a vital role in your physical and mental health, including digestion, immunity, metabolism, mood and prevention of chronic disease. The ability to digest and absorb nutrients from food effectively is one of the cornerstones of good health. The gut microbiome is home to 70% of your immune system and plays a key role in metabolising nutrients, regulating energy levels, and producing neurotransmitters including 95% of your serotonin and 50% of your dopamine! It’s little wonder it’s now recognised as your second brain.
A healthy gut absorbs the required nutrients from food and rids the body of waste and harmful substances. The key signs of a healthy gut are regular and pain-free bowel movements, consistent energy, limited or no bloating, healthy bowel transit time, mental clarity, glowing skin, sleeping though the night, less depression and anxiety, and healthy reactions to food and stress.
It is important for the microorganisms in your digestive system to be balanced so the gut can function well, processing and absorbing nutrients to fuel your body. Some of the symptoms of poor gut health are food sensitivities, bloating after every meal, inconsistent stools and excess gas, skin imbalances, sleep disturbances, constant fatigue, mental health imbalances and a weakened immune system. Diet, stress levels, physical activity, medication use (such as antibiotics), sleep patterns, and environmental exposures all play a role. The good news is we can easily change our gut microbiome in just a week or two of making changes to our diet.
Take the gut health quiz to learn about your health in the four areas of your digestive system, and practical steps you can take to help
Yes. The speed and extent of microbiome changes depend on the degree of intervention and your own body’s ability to adapt. But good change is possible in as little as a week or two. But consistency is key. A fibre-rich diet with fermented food sustained over weeks leads to greater microbial diversity and enhances gut health. And if you can maintain a healthy diet, manage stress, and avoid microbiome disruptors such as processed foods and excessive alcohol, you will be rewarded with profound microbiome changes. Good habits over six to twelve months will allow for the development of a resilient microbial community capable of supporting immune function, reducing the risk of chronic diseases, and enhancing mental health through the gut-brain axis.
Prebiotics are foods that feed our existing gut bacteria and encourage a diverse community of microbes. Prebiotic-rich foods include vegetables like garlic, onions, leeks and asparagus; fruits such as bananas, apples and berries; and legumes like chickpeas and lentils. Wholegrains like oats and barley can be a good source of prebiotics too.
Probiotics are foods, or supplements, that contain live bacteria and yeasts to replenish the gut microbiome, adding to your existing supply of friendly microbes to strengthen those communities and bring your microbiome back to balance. This includes fermented foods like live yoghurt, sauerkraut, kimchi, kefir, miso, tempeh, kombucha and some aged cheeses.
I specialise in blood chemistry analysis, hormonal health, gut health and genetics, weaving integrative health practices into everything I do.
As a Clinical Nutritionist, I train Health Practitioners to read bloodwork differently, mentor new graduates entering the field, and share insights with businesses and community groups each week.
My approach is all about making health simple, practical, and truly transformative.
