Fibre is the least glamorous nutrient and probably the one with the biggest gap between what we need and what we eat. Adults should aim for around 30 g a day; most people in the UK get closer to 18 g. That shortfall is quietly linked to worse digestion, higher cholesterol, less stable energy and a hungrier afternoon. The good news: closing the gap doesn't take supplements or a new diet — just a few deliberate swaps.
What fibre actually does
Fibre is the part of plant food your body can't digest, and that's exactly the point. It passes through largely intact, and on the way it does several jobs:
- Slows digestion, so the energy from a meal arrives gradually instead of as a spike-and-crash. That's why a high-fibre breakfast keeps you full to lunch.
- Feeds your gut bacteria, which ferment certain fibres into compounds that support gut and immune health.
- Lowers cholesterol — soluble fibre binds to it and carries it out.
- Keeps things moving, the job everyone associates with fibre and the one insoluble fibre handles.
Soluble vs insoluble — and why you want both
- Soluble fibre dissolves into a gel. It's what slows digestion and lowers cholesterol. Find it in oats, beans, lentils, apples, citrus and carrots.
- Insoluble fibre doesn't dissolve; it adds bulk and speeds transit. Find it in wholegrains, wheat bran, nuts and the skins of fruit and veg.
You don't need to count the two types. Eat a range of plants and you'll get both.
Where the easy wins are
Hitting 30 g sounds like a lot until you see how it stacks up:
- Pulses are the heavyweights. A portion of cooked lentils or beans brings 7–8 g in one go. Stir a tin of chickpeas into a stew or curry and you've done a quarter of the day.
- Switch the white for brown. Wholemeal bread, brown rice and wholewheat pasta roughly double the fibre of their white versions for zero extra effort.
- Leave the skins on. Most of an apple's, potato's or carrot's fibre is in or just under the skin. Scrub, don't peel.
- Start the day with oats. Porridge or overnight oats is one of the simplest 5–8 g you'll bank before 9am.
- Snack on nuts and fruit instead of crackers — a handful of almonds and a pear is a couple of grams more and far more filling.
Go slow and drink water
Two cautions. First, ramp up gradually — jumping from 15 g to 35 g overnight will leave your gut bloated and unhappy. Add one high-fibre swap at a time over a couple of weeks. Second, fibre needs water to work; it absorbs liquid as it moves through you, so a higher-fibre diet means drinking a bit more.
Building it in without thinking about it
The reliable way to hit fibre every day isn't willpower at each meal — it's planning meals that are built on plants in the first place. That's a quiet advantage of a structured weekly plan: when pulses, wholegrains and vegetables are the default ingredients, 30 g stops being a target you chase and becomes a number you pass without noticing. Yuzo leans on exactly those ingredients when it builds a week, so a high-fibre diet is the path of least resistance rather than a daily decision.
Getting started
This week, make one swap and keep it: brown bread instead of white, or a tin of beans into one dinner. Add the next swap the week after. Small, stacked changes are how 18 g becomes 30 g without it ever feeling like a diet.
