What is gut health?
When we talk about your gut, we mean your gastrointestinal system which includes your stomach, small intestine and colon.
You may not know it, but gut health plays a huge role on both our mental and physical health and can have a significant impact on how we feel day to day.
Why is gut health so important?
Our gut is responsible for putting our body into working order. As it breaks down the foods we eat, our gut absorbs nutrients that support our body’s functions.
Throughout your gut, your body can produce “good” bacteria and help keep “bad” bacteria in check. When you have a healthy balance of bacteria in your gut, you’re more likely to feel and stay healthy.
Here’s what VicHealth CEO Dr Sandro Demaio says is true about gut health and how to keep it healthy.
What’s true and false when it comes to gut health?
- The way your gut functions lets you know what’s going on inside your body. For example, pooping regularly is a sign of a healthy gut.
- Your gut bacteria are influenced by what you eat and put into your body. For example, antibiotics, while important for fighting infections, can have a negative impact on our gut by wiping out ALL bacteria, including the good ones you need to keep healthy.
- A way to counteract the negative impact of antibiotics on the gut is to consume probiotics.
- Probiotics are “good” bacteria and can make your immune system stronger, BUT they’re not all the same. The best sources are fermented vegetables like kimchi and sauerkraut.
- Prebiotics are the food source of probiotics and can help the growth of helpful bacteria in your gut. You can find them in fruits, vegetables and legumes, such as chickpeas and lentils.
- Soluble and insoluble fibres, such as oats and brown rice, can also do a lot to support gut health as they help improve digestion, lower blood sugar and soften stool.
- Unfortunately, there is no quick fix or miracle cure for good gut health. There’s no scientific evidence that manuka honey or any other product will rapidly heal an unbalanced microbiota (the makeup of bacteria in your gut).
- There’s also no scientific evidence that colon cleansing improves health or is beneficial at all.
- Stress can change your gut. That’s why it’s important to take time to Look after your mental wellbeing.
- Nothing replaces a varied wholefood diet, made up of mostly vegetables and fruit. A good way to know if the meal will be good for your gut is by identifying the number of different food colours, “eat a rainbow every day”.
Top tips on looking after your gut health
1. Eat high fibre foods that fuel your gut
To ensure your body can produce as much “good’ bacteria as possible, make sure you’re eating fresh fruits and vegetables and foods that are high in fiber.
Remember your gut bacteria is influenced by what you eat, so it’s important to give it the best fuel so good bacteria grow to fight off ‘bad’ bacteria. Eat lots of prebiotics (vegies, lentils, beans etc), the food source of probiotics that help to grow helpful bacteria in your gut.
Here’s a list of some high fiber foods that help grow “good” bacteria:
Jerusalem artichokes, chicory, garlic, onion, leek, shallots, spring onion, asparagus, beetroot, fennel bulb, green peas, snow peas, sweetcorn, savoy cabbage
Chickpeas, lentils, red kidney beans, baked beans, soybeans
Custard apples, nectarines, white peaches, persimmon, tamarillo, watermelon, rambutan, grapefruit, pomegranate. Dried fruit (eg. dates, figs)
- Bread / cereals / snacks
Barley, rye bread, rye crackers, pasta, gnocchi, couscous, wheat bran, wheat bread, oats
- Nuts and seeds
Cashews, pistachio nuts
