I counted it out one morning last week, sitting on the sand at Terrigal Beach with a coffee going cold beside my journal: eggs, toast, a flat white. Not a scrap of fibre in sight until lunch. It’s not a moral failing, it’s just how breakfast tends to go for a lot of us, and it got me thinking about how quietly this one nutrient gets sidelined.
The thing I keep coming back to is that fibre doesn’t get the airtime protein does. Everyone’s talking macros and muscle, and fibre sits there in the background doing unglamorous, steady work. But when I’ve gone through patches of eating more of it, mostly by accident, I’ve noticed the difference in how even my days feel. Steadier energy. Less of that mid-afternoon flatness. Sleep that doesn’t feel quite so patchy.
What fibre actually is, in plain terms
Fibre is the part of plant food our bodies can’t fully break down; it moves through the gut largely intact, feeding the bacteria that live there and adding bulk along the way. There are two broad types, soluble and insoluble, and most whole foods contain a mix of both. Nutrition Australia and the Eat for Health guidelines from the Australian government both point to whole grains, legumes, vegetables, fruit and nuts as the main sources, and the current recommendation sits around 25 to 30 grams a day for most adults, though very few of us get near that.
I’ll admit I used to think fibre was mostly about avoiding sluggishness. It’s more than that, or at least it feels like more than that. Dietitians often describe it as food for the gut microbiome, the trillions of bacteria that seem to play a role in digestion, immunity and even mood, according to CSIRO’s ongoing gut health research. I’m not going to claim it fixes anything. What I can say, from paying attention to my own patterns in that scrappy journal I keep, is that the days I eat more plants are usually the days I feel more even.
Where most of us fall short
It’s rarely one big gap. It’s breakfast without a plant in sight, a lunch built around white bread, dinner where the vegetables are an afterthought rather than the main event. I did this for years without really noticing, because none of it looked like a bad diet on paper.
The pattern I see most often, in my own kitchen and in conversations with friends, is that fibre gets crowded out by convenience. White rice instead of brown. Juice instead of the whole piece of fruit, which strips out most of the fibre along with the pulp. Snacks that are technically fine but contribute almost nothing structurally. None of this is a failing, it’s just what happens when life is flat out and cooking has to be fast.
What actually helps, without overhauling everything
I don’t think the answer is a fibre supplement or a strict meal plan. What actually helps, in my experience, is small substitutions that stack up over a week rather than one dramatic overhaul over a weekend.
Swapping white rice for brown or a grain mix. Leaving the skin on vegetables where it makes sense. Adding a tin of lentils or chickpeas to something that didn’t ask for them. Choosing wholemeal or grainy bread most days rather than white. None of these feel like sacrifice, and that’s the point, because the changes that last are the ones that don’t feel like a project.
A grain bowl is one of the easiest ways I’ve found to get several fibre sources into one meal without thinking too hard about it. Something like our warm grain bowl with roasted roots and labne does this without any fanfare, just grains, roasted vegetables and a good dollop of something creamy to pull it together. Legumes are another quiet workhorse; the chickpea and roast capsicum salad is one I make on repeat through the colder months, mostly because it holds up well as leftovers.
Mornings are where I’ve made the biggest difference
Breakfast was my weak point, and honestly still is some mornings. But when I do get it right, it tends to be something with oats, seeds or beans in it rather than just toast. Baked beans done properly, like the smoky baked beans with soft poached egg, are a good example of a meal that feels indulgent but is quietly doing a lot of work in the fibre department. On slower weekends I’ll make buckwheat and banana pancakes with toasted seeds, which manage to feel like a treat while still bringing something to the table nutritionally.
I’ve written before about how a solid morning routine that actually sticks tends to flow into better choices later in the day, and I think that’s true of fibre specifically. Start the day with something that has a bit of substance to it and the rest of the day’s meals seem to follow that lead, at least in my experience.
The gut connection, without overstating it
I want to be careful here, because it’s easy to slide into claims that aren’t mine to make. I’m not a clinician and I won’t pretend food fixes anything specific. What I can say is that when I’ve paid attention to fibre alongside other small gut health habits, the kind covered in our piece on small gut health habits that actually fit real life, I’ve noticed things feel more settled generally. Digestion, energy, even how I sleep. Whether that’s fibre alone or the whole pattern of eating better, I honestly can’t separate it out, and I’d be suspicious of anyone who claimed they could.
Healthdirect’s general guidance on diet and digestion says much the same thing in more measured language: fibre is one part of a broader pattern, not a fix on its own. That feels like the honest way to say it.
My one quiet opinion on all this
If I’m being straight about it, I reckon the fibre conversation gets buried under too much noise about protein and too little practical guidance on plants. Everyone wants the quick macro number, and fibre doesn’t lend itself to that kind of headline. But it’s arguably the easiest nutritional gap to close, because it doesn’t require cutting anything out, just adding a bit more in. That’s the part that gets lost.
We’ve got a whole piece on simple ways to eat more plants each week if the idea of tracking grams feels like too much admin, which, fair dinkum, it usually is for most of us on a Tuesday night.
Where I’ve landed on it
The days I get fibre right aren’t the days I’ve planned meticulously. They’re the days I’ve had lentils instead of just rice, or kept the skin on the sweet potato, or reached for the wholemeal loaf out of habit rather than thought. Small, unremarkable choices that don’t ask much of me.
I still don’t hit 30 grams most days, if I’m honest. But I’m closer than I was a year ago, and the difference in how I feel, particularly through the afternoon slump, has been enough to keep me at it. That’s really all I can offer here, not a rule, just an observation from someone who keeps a messy journal and pays attention to her own patterns.
