- What it is: A practical guide to improving your gut health in Australia using simple, evidence-based food choices.
- How it works: The approach focuses on increasing daily fibre (aiming for 25g-30g), incorporating probiotic-rich foods like yoghurt and kimchi, and adding prebiotic sources like onions, garlic, and oats to support a healthy gut microbiome.
- Key Benefits: These simple dietary changes can quickly improve digestive wellness, bowel regularity, and overall gut function. Adequate hydration (8-10 cups daily) is crucial for these strategies to work effectively.
If you find the world of gut health nutrition a bit confusing, you’re not alone. While many Australians know that diet affects digestive wellness, turning that knowledge into practical, everyday food choices can feel like a real challenge.
The good news is that supporting your gut health doesn’t require expensive supplements or restrictive meal plans. Simple, evidence-based dietary changes can significantly improve your digestive comfort, bowel regularity, and overall gut function.
This guide shows how simple, practical food choices can make a real difference to your digestive wellness. We explore the straightforward benefits of boosting your daily fibre, incorporating probiotic and prebiotic-rich foods, and staying well-hydrated to support a happy, healthy gut.
Fibre as the Foundation of Good Gut Health
Think of dietary fibre as the foundation of good gut health. The problem is, a majority of Australian adults simply are not getting enough each day.
What Is Dietary Fibre?
Dietary fibre comes from plants, and it is a type of carbohydrate that your body cannot fully digest. It passes mostly intact through your stomach and small intestine to reach your colon, where it begins to provide its benefits.
Fibre is not a single substance. It comes in two main types, both of which are beneficial for your gut.
Soluble fibre
- Dissolves in water to form a gel.
- Helps regulate blood sugar and cholesterol.
- Feeds your good gut bacteria.
- Found in oats, legumes, apples, and citrus fruits.
Insoluble fibre
- Does not dissolve in water.
- Adds bulk to your stool, promoting regular bowel movements.
- Found in wholegrain bread, brown rice, nuts, and seeds.
Most high-fibre foods contain a mix of both types.
How Much Fibre Do You Need?
Health authorities in Australia recommend that:
- Men aim for 30 grams per day.
- Women aim for 25 grams per day.
Most Australians only manage about 15-20 grams daily, which is well below these targets.
Practical Tips for Increasing Fibre Intake
- Start gradually to avoid bloating and gas. Add about 5 grams per week until you reach your goal.
- Increase your fluids. Fibre needs water to work properly, so aim for 2-3 litres of fluid a day.
- Make simple swaps. Switch white bread for wholegrain, or white rice for brown rice, quinoa, or barley.
- Add fibre to familiar dishes. Sprinkle chia seeds on yoghurt, add lentils to soups, or include extra vegetables in your main meals.
- Choose fruit for snacks. An apple or a pear is a great source of fibre.

What If Fibre Causes Bloating
For some people, particularly those with irritable bowel syndrome (IBS), a rapid increase in fibre can cause gas and bloating. If this happens, try increasing your intake more slowly and make sure you are drinking enough water. If symptoms continue, it is a good idea to consult a gastroenterologist or dietitian.
Probiotics & Prebiotics are Your Gut’s Support Team
Probiotics and prebiotics are a powerful team. They work together to support a healthy gut microbiome, which is the complex community of trillions of bacteria, viruses, and fungi living in your digestive system. A healthy microbiome helps with digestion, produces nutrients, supports your immune system, and can even influence your mood.
Probiotics Beneficial Live Bacteria
Probiotics are live microorganisms that provide health benefits when you consume them in the right amounts. You can find them in foods like:
- Yoghurt Choose products that state they contain “live cultures”.
- Kefir A fermented milk drink that contains a wide variety of probiotic strains.
- Fermented vegetables Unpasteurised sauerkraut and kimchi are great options.
- Miso and Tempeh Fermented soybean products used in cooking.
- Kombucha A fermented tea, but check the label for sugar content as some commercial brands can be very high.
For most people, probiotic-rich foods are enough. However, supplements may be helpful after a course of antibiotics or for managing specific conditions like IBS, but it is best to consult your doctor for recommendations.
Prebiotics Food for Good Bacteria
Prebiotics are specific types of fibre that act as food for your beneficial gut bacteria, helping them grow and thrive. You do not need special products to get them. They are found in many everyday plant foods.
Excellent sources of prebiotics include:
- Vegetables Onions, garlic, leeks, and asparagus.
- Fruits Bananas (especially slightly underripe ones) and apples.
- Legumes Lentils, chickpeas, and beans.
- Whole grains Oats and barley are particularly good sources.
For best results, eat a variety of probiotic-rich foods alongside plenty of prebiotic-rich plant foods. This combination gives your gut microbiome extensive support.
Hydration for Digestive Health
It sounds simple, but proper hydration is vital for your digestive system to work well. Despite this, many Australians do not drink enough water day to day. Water helps to prevent constipation by softening stool, supports nutrient absorption, and helps maintain a healthy digestive tract lining.
How Much Water Do You Need?
A healthy daily fluid intake is:
- Men: 3 litres.
- Women:1 litres.
You may need more if you are exercising, in hot weather, or have a high-fibre diet. Water is always the best choice, but herbal teas and moderate amounts of tea and coffee also count towards your fluid intake.

10 Gut-Friendly Foods to Add to Your Shopping List
These ten foods, all readily available in Australia, are fantastic for supporting your digestive health.
- Oats Packed with a special soluble fibre called beta-glucan, which has a prebiotic effect.
- Legumes (Lentils, Chickpeas, Beans) Exceptionally high in fibre and resistant starch, which feeds beneficial gut bacteria.
- Natural Yoghurt Contains live probiotic bacteria and is a great source of calcium.
- Leafy Greens (Spinach, Kale) Rich in fibre and magnesium, which helps with constipation.
- Apples High in pectin, a soluble fibre that has a prebiotic effect. Eat the skin for the most benefit.
- Kimchi and Sauerkraut These fermented vegetables provide probiotics and enzymes that support digestion. Choose unpasteurised versions from the fridge section.
- Bananas A great source of prebiotic fibre, especially when they are slightly underripe.
- Chia Seeds and Ground Flaxseed Extremely high in fibre and rich in omega-3 fatty acids. They form a gel with liquid that supports regularity.
- Sweet Potato High in fibre and contains resistant starch, especially when cooled after cooking.
- Kefir A fermented drink with a more diverse range of probiotic strains than yoghurt.
Building Your Gut-Healthy Eating Plan
Lasting change comes from making small, gradual shifts, not from completely overhauling your diet.
The Gut-Healthy Plate
A simple way to build your meals is to follow this template:
- ½ plate: Vegetables (cooked or raw) for fibre and prebiotics.
- ¼ plate: Lean protein (fish, chicken, legumes, tofu) for satiety.
- ¼ plate: Whole grains or starchy vegetables for fibre and energy.
- Add: Fermented foods like yoghurt or kimchi as a side or condiment.
When Diet Alone Is Not Enough
If you are following a healthy diet but still experience digestive discomfort, it might be time to seek professional guidance. There could be specific food intolerances or underlying conditions like IBS that need to be addressed. A GP, gastroenterologist, or dietitian can provide the assessment you need.
Your Gut Health Journey
Looking after your gut health with the right food is one of the best things you can do for your overall wellbeing. It does not have to be complicated. Simple choices like adding more vegetables, whole grains, and fermented foods can create the foundation for excellent gut health.
