How Much Fibre Is in an Apple? Everything You Need to Know

A medium apple contains around 4g of fibre, making it an easy way to contribute towards your daily fibre intake. Much of an apple’s fibre is found in or close to the skin, so eating the whole fruit with the skin on will give you more fibre than peeling it.

In the UK, adults are advised to aim for around 30g of fibre a day. One medium apple can therefore provide roughly 10–15% of your daily target.

But are apples actually high in fibre, which varieties contain the most, and how do they compare with bananas and other fruits?

How much fibre is in an apple?

A medium apple with its skin contains around 4g of fibre. The exact amount will vary depending on the size and variety of the apple.

Apples contain both soluble and insoluble fibre. One of the best-known types of soluble fibre found in apples is pectin, which is fermented by bacteria in the large intestine.

If you're trying to increase your fibre intake, eating the skin rather than peeling your apple is an easy way to get more from the fruit.

Are apples high in fibre?

Apples contain a useful amount of fibre, but they aren't among the highest-fibre fruits. A medium apple provides around 4g, while fruits such as raspberries, avocado and passion fruit provide more fibre per 100g.

That doesn't make apples a poor choice. They're an affordable and convenient way to add another source of plant fibre to your diet.

Rather than focusing on a single high-fibre food, eating a variety of fruits, vegetables, whole grains, nuts, seeds and pulses can help you work towards your daily fibre target.

Is one apple a day enough fibre?

No, one apple a day isn't enough to meet your daily fibre needs. A medium apple provides around 4g of fibre, while UK adults are advised to consume around 30+g each day.

An apple can certainly contribute towards that total, but you'll need plenty of other fibre-containing foods throughout the day.

For example, you could combine fruit with oats and chia seeds at breakfast, add whole grains and vegetables at lunch, and include beans, lentils or other pulses with your evening meal.

This is essentially the idea behind fibre layering: adding different sources of fibre throughout your day rather than trying to get a huge amount from one meal.

How can I get 30g of fibre a day?

You can reach 30g of fibre a day by including different fibre-rich plant foods across your meals and snacks. You don't need to rely on huge portions or a single particularly high-fibre food.

A day could include foods such as:

• Porridge oats topped with fruit and seeds
• An apple as a snack
• Wholegrain bread, wraps, rice or pasta
• Beans, chickpeas or lentils
• Several portions of vegetables
• Nuts and seeds
• Berries or other fruit

If you're currently eating significantly less fibre, increase your intake gradually rather than jumping straight to 30g. Drinking enough fluid alongside a higher-fibre diet is also important.

We've covered this approach in more detail in our guide to fibre layering vs fibremaxxing.

Which has more fibre, an apple or a banana?

A medium apple generally contains more fibre than a medium banana, although the exact amount depends on the size of each fruit. A medium apple with its skin provides around 4g of fibre, compared with roughly 3g in a medium banana.

Both can still contribute towards a fibre-rich diet, and there's no need to choose one over the other. They also contain different carbohydrates and plant compounds, so variety is useful.

If you're interested in the comparison, our guide to how much fibre is in a banana also looks at green bananas and resistant starch.

What fruit has the most fibre?

Passion fruit is one of the most fibre-rich commonly available fruits, providing around 10g of fibre per 100g. Raspberries, avocados and blackberries are also higher in fibre than apples.

As a rough comparison:

However, you don't need to eat whichever fruit happens to contain the most fibre. Eating different fruits and plant foods gives you a wider variety of fibres and nutrients.

Does peeling an apple reduce the fibre?

Yes, peeling an apple reduces its fibre content because some of the fruit's fibre is found in the skin. If you enjoy apple skin, eating the whole fruit is therefore an easy way to maximise the amount of fibre you get from it.

Just give the apple a good wash before eating it.

Are apples good for gut health?

Apples can form part of a gut-friendly, fibre-rich diet. Alongside insoluble fibre, apples contain the soluble fibre pectin, which can be fermented by microbes in the large intestine.

Rather than expecting one food to transform your gut health, focus on your overall diet. Eating a wide range of fibre-containing plant foods gives your gut microbes access to different substrates.

The bottom line: how much fibre is in an apple?

A medium apple with its skin contains around 4g of fibre. That's a useful contribution towards the recommended 30g of fibre a day for UK adults, although an apple alone won't get you close to your full daily requirement.

Eating apples with their skin can help you get more fibre from them, but variety is key. Combine fruit with vegetables, whole grains, beans, pulses, nuts and seeds to build a more diverse fibre intake throughout the day.
