Fibre is the part of plant foods that your body cannot digest. That’s exactly what makes it so powerful.

While it passes through your digestive system largely intact, it does extraordinary things along the way feeding your beneficial gut bacteria, slowing the absorption of sugar into your bloodstream, keeping your bowels moving, and reducing inflammation throughout the body.

Fibre isn’t just a digestive aid. It directly influences your mood, your energy, your hormones, and your long-term health.

So How Much Do You Actually Need?

The NHS recommends 30g of fibre per day for adults. Most people in the UK are getting around 18g barely half of what their body needs.

To put 30g into perspective:

1 slice of wholegrain bread = roughly 2g

1 medium apple = roughly 4g

portion of broccoli = roughly 3g

1 tin of chickpeas = roughly 10g

1 tablespoon of chia seeds = roughly 5g

You can see how quickly the gap appears — especially if your diet includes a lot of processed or refined foods, which contain very little fibre at all.

What Happens When You Don’t Get Enough?

Low fibre intake is linked to:

Unstable blood sugar without fibre to slow things down, sugar hits your bloodstream fast, spiking cortisol and triggering that mid-morning anxiety or afternoon crash.

Poor gut health your beneficial gut bacteria literally feed on fibre. Without it, they starve, and your microbiome diversity drops. Since 90% of your serotonin is produced in your gut, this has a direct impact on your mood.

Sluggish digestion — constipation, bloating, and that heavy, uncomfortable feeling are classic signs of too little fibre.

Increased inflammation low fibre diets are associated with higher levels of chronic inflammation, which affects everything from your energy levels to your immune system.

5 Simple Ways to Eat More Fibre Every Day

You don’t need to overhaul your diet overnight. Small, consistent additions make a huge difference.

1Add seeds to everything

A tablespoon of chia seeds or ground flaxseed into your yoghurt, porridge, or smoothie adds 4–5g of fibre instantly. You won’t even taste it.

Choose whole grains over refined

Swap white bread for wholegrain, white rice for brown or wild rice. The fibre content can be two to three times higher.

Eat the skin

Leave the skin on your potatoes, apples, courgettes, and cucumbers. That’s where a significant portion of the fibre lives.

Add legumes to your meals

Chickpeas, lentils, black beans, and butter beans are fibre powerhouses. Add a handful to soups, salads, or stews  even one portion a day makes a noticeable difference.

Aim for variety, not just quantity

Different plants feed different strains of beneficial gut bacteria. Try to eat 30 different plant foods a week — this includes fruits, vegetables, wholegrains, nuts, seeds, herbs, and spices. It sounds like a lot, but a mixed salad alone can contain eight to ten.

One Important Thing to remember

If you’re currently eating very little fibre, increase it gradually. Adding too much too quickly can cause bloating and discomfort as your gut bacteria adjust. Increase slowly, drink plenty of water, and give your digestive system time to adapt.

The Bottom Line

Fibre is one of the most powerful and most underrated tools for your health. It stabilises your blood sugar, supports your mood, nourishes your gut, and protects your long-term wellbeing — all for the cost of a handful of seeds or an extra portion of vegetables.

Thirty grams a day. That’s your goal. And with small, intentional changes, it’s completely achievable.
