You’ve heard me talk about the importance of gut health quite a bit over the last few years. Emerging research highlights how connected our gut is to the rest of our body. A healthy gut doesn’t just mean fewer digestive issues—it’s linked to a stronger immune system, better hormonal balance, improved mood, and reduced inflammation. There’s even growing evidence that gut health can affect sleep quality, weight management, and cognitive function.
As we get older, supporting our gut health becomes even more important. Digestion can slow down due to hormonal changes, reduced muscle tone in the digestive tract, and often a decrease in physical activity. This can lead to symptoms like bloating, constipation, and a slower metabolism. A healthy gut microbiome not only helps keep digestion running smoothly but also plays a major role in hormone balance, immune support, and nutrient absorption.
We can support our gut health through diet and exercise, yet two words often come up that confuse people: prebiotics and probiotics. You can see the problem here—they sound similar and are often mentioned together, yet they play very different roles in the body. Understanding what each of them does and why both are equally important can help you take better care of your digestion, immunity, and even your mood.
Let’s break them down in simple terms:
Probiotics
These are live microorganisms—mainly bacteria and some types of yeast—that offer health benefits when consumed in adequate amounts. You often hear them called “good” or “friendly” bacteria because they help maintain a healthy balance in our gut microbiome—the vast community of microbes that live in our digestive system.
Our bodies naturally contain both good and bad bacteria. When we’re healthy, the good bacteria help keep the bad bacteria at bay. When that balance is thrown off—through antibiotics, illness, stress, poor diet, or lack of sleep—probiotics can help restore harmony. They support digestion, nutrient absorption, and immune function, and may even play a role in mental health through the gut-brain connection.
Where to find probiotics
Probiotices are found in fermented foods such as yoghurt (with live cultures), kefir, sauerkraut, kimchi, miso, tempeh, and certain pickles. Probiotic supplements are also widely available and can be especially helpful after a course of antibiotics or during times of digestive discomfort.
Prebiotics
Prebiotics are not bacteria at all. Instead, they’re types of fibre that act as food for your good gut bacteria. While our bodies can’t digest these fibres, the beneficial bacteria in our intestines can. When we eat prebiotic-rich foods, we’re essentially feeding our gut microbiome and helping it thrive. Think of it this way: probiotics are the living organisms, and prebiotics are what they eat. Without prebiotics, the good bacteria in our gut wouldn’t have the nourishment they need to grow, multiply, and do their job effectively.
Where to find prebiotics
Prebiotics are found naturally in many plant-based foods. Some of the best sources include onions, garlic, leeks, asparagus, Jerusalem artichokes, bananas (especially slightly green ones), oats, apples, and chicory root. A varied, fibre-rich diet with plenty of vegetables, fruits, whole grains, and legumes will naturally boost your prebiotic intake.
How to Optimise Your Gut Health
For optimal gut health, you need both prebiotics and probiotics working together. Imagine your gut as a garden: probiotics are the seeds, and prebiotics are the fertiliser. One without the other doesn’t work as well. If you take probiotic supplements but don’t eat enough prebiotic foods, those beneficial bacteria may not survive long enough to be effective. On the flip side, if you eat prebiotics but don’t have enough good bacteria to begin with, there’s nothing there to feed. This is why a balanced, diverse diet is so important.
My best tips for a healthy digestive system
Instead of focusing on just one superfood or supplement, aim for variety. Remember the rainbow on the plate? This means consuming different types of colourful vegetables, fruits, fermented foods, and fibre. Together, you give yourself the best chance of supporting a thriving gut microbiome, which benefits your overall health.
Taking care of your gut by including prebiotic and probiotic foods in your diet is a gentle, natural way to support your long-term wellbeing. You don’t need to overcomplicate it or follow extreme diets or routines. Just start adding more whole, real foods and tuning into how your body responds.
Drink plenty of water and include regular movement in your daily routine to help keep your digestive system—and your whole body—feeling its best.
Sugar and Gut Health
When it comes to gut health, too much sugar can create an imbalance in the gut microbiome by feeding harmful bacteria and yeasts, which weakens the resilience of the gut ecosystem. This means the harmful bacteria can take over, leaving us with a host of problems that, over the long term, can contribute to disease. A little sugar is okay if you’re mainly eating a balanced, healthy diet full of fresh, whole foods.
If you’re new to fermented foods or high-fibre vegetables, it’s okay to start slowly. Most are now widely available in health stores and supermarkets. Or you could make your own, which is more affordable and not as hard as you might think!
The key is to just start. Add one or two new ingredients at a time, drink plenty of water, and notice how you feel. Over time, your gut will begin to thank you, and you may find your energy, digestion, and even your mood improving along the way.
