Dates and Fibre: What a 100g Serving Actually Gives You

Dates and Fibre: What a 100g Serving Actually Gives You

The UK has a fibre problem. Adults are advised to eat 30g of fibre a day. According to the British Nutrition Foundation, the average adult manages about half of that, and only around 4 in 100 adults hit the target.

Dates are often recommended as a fix. But how much fibre is really in them, what kind is it, and is 100g a sensible amount to eat? Here are the numbers, with the context most nutrition tables leave out.

The 100g Numbers at a Glance

Nutrition tables quote dates per 100g because it makes comparison easy. Here is what that reference amount contains, based on typical values for soft and semi-dry dates.

Typical reference values. Saudi varieties such as Ajwa, Sukri and Mabroom fall in a similar range, but moisture, harvest and ripeness change the exact numbers.

The headline: 100g of dates gives you roughly a quarter of your daily fibre target.

What 100g of Dates Looks Like

Nobody weighs dates at the kitchen counter, so here is the translation.

Variety Type

Approximate Weight per Date

Dates in 100g

Medjool (jumbo)

20g to 25g

Medium Saudi dates (e.g. Sukri, Mabroom, Amber)

10g to 15g

About 7 to 10

Small, dense dates (e.g. Ajwa)

7g to 10g

About 10 to 14

Pitted weights vary by variety and harvest.

That tells you something straight away. Four Medjool is a very different eating experience from twelve small Ajwa, even though both weigh 100g.

What Kind of Fibre Is in Dates?

Dates contain both main types of dietary fibre, with insoluble fibre making up most of it.

Insoluble Fibre

Mostly cellulose, hemicellulose and lignin from the fruit's skin and flesh. It adds bulk to stools and helps food move through the gut. This is the fibre behind dates' reputation for supporting regularity.

Soluble Fibre

A smaller share, largely pectins. Soluble fibre forms a gel in the gut, slows digestion and helps blunt the rise in blood sugar after eating.

Polyphenols Travel With the Fibre

Dates are also rich in polyphenols, plant compounds that are partly bound to fibre. Much of this reaches the large intestine, where gut bacteria break it down. It is one reason researchers are interested in dates beyond basic nutrition. Our article on how dates naturally support healthy digestion and gut health explores this in more depth.

How Dates Compare With Other Fibre Sources

Here is the comparison most articles skip: fibre per 100g and fibre per 100 calories. The second number shows how efficiently a food delivers fibre within your daily energy budget.

Typical reference values; brands and varieties differ.

What this shows:

  • Dates beat raisins comfortably on fibre, gram for gram and calorie for calorie.

  • Dates are roughly on par with prunes and apricots per 100g.

  • Fresh fruit like apples wins on fibre per calorie, because it is mostly water.

So dates are a strong fibre source in a compact, portable form. They are not the most calorie-efficient one. That is why portion matters.

Can Dates Be Called "High Fibre"?

Under UK nutrition claim rules, a food can be labelled a "source of fibre" at 3g per 100g, and "high fibre" at 6g per 100g. Plain dates, at around 6.7g to 8g per 100g, meet the high fibre threshold.

They also qualify as high in potassium, which requires at least 30 percent of the reference intake per 100g, or 600mg.

100g Is a Reference, Not a Recommended Snack

This is where the numbers need honesty. 100g of dates is about 280 kcal and around 65g of sugar. That is a lot for one sitting.

The NHS counts 30g of dried fruit as one portion of your 5 A Day, and suggests eating it with meals. Here is what realistic portions give you:

Digestive Tolerance: Who Should Go Slowly

Fibre is good for most people, but a sudden jump can cause bloating and wind. Build up gradually over a week or two and drink plenty of water.

A Note for People With IBS

Dates contain fructans and sorbitol, two FODMAPs that can trigger symptoms in people with irritable bowel syndrome. According to Monash University's FODMAP data, as reported by specialist IBS dietitians, a low FODMAP serve is around one Medjool (about 20g) or about 30g of smaller dried dates. Larger portions may cause symptoms in sensitive people. If you have IBS, work with a registered dietitian to find your own threshold.

Does Variety Change the Fibre?

A little. Drier, denser dates tend to carry slightly more fibre per 100g than soft, moist ones, because there is less water diluting the flesh. That means a firm, chewy variety such as Mabroom (read about Mabroom dates and their unique chewy texture) or a golden Sukri will usually give you a touch more fibre per gram than a very soft date.

Whole dates also beat processed date products. Once dates are blended into syrups or heavily processed snacks, some of the fibre is lost or diluted with other ingredients. Our comparison of fresh dates versus processed, packaged date snack products covers this in detail.

Getting the Most Fibre From Your Dates

  • Eat them whole. Skin included; that is where much of the insoluble fibre sits.

  • Choose unprocessed dates. Nothing added, nothing removed.

  • Pair them with other fibre sources such as oats, nuts and seeds.

  • Spread them across the day rather than eating 100g in one go.

  • Store them properly so they stay pleasant to eat; our guide on how to store your dates to keep them fresh for months explains how.

Why Roots Dates

Roots dates are sourced directly from Saudi Arabia and sold exactly as they grow: no polishing, glazing, syrup or preservatives. That means the fibre and minerals on the nutrition table are the ones in your pack. If you want to try several varieties and compare textures, the Everyday Energy Bundle gives you six varieties in 450g packs, or you can browse the full range. For a large, dense date with a smooth bite, try Amber.

Frequently Asked Questions

How much fibre is in 100g of dates?

About 6.7g to 8g, depending on variety and moisture. That is roughly 22 to 27 percent of the UK adult target of 30g a day.

How many dates should I eat a day for fibre?

For most adults, 2 to 4 medium dates, or 1 to 2 Medjool, alongside other fibre sources is a sensible amount. That adds 2g to 4g of fibre without a large sugar load.

Are dates high in fibre?

Yes. At more than 6g of fibre per 100g, plain dates meet the UK threshold for a "high fibre" claim.

Do dates help with constipation?

Their mostly insoluble fibre adds bulk and can support regularity, especially with enough water. If constipation persists, speak to your GP or pharmacist.

Are dates or prunes better for fibre?

They are similar per 100g, with about 7g each. Prunes also contain more sorbitol, which has a stronger laxative effect.

A few dates a day will not fix the UK fibre gap by themselves. As part of a balanced diet, they are one of the easiest and most enjoyable ways to close it.
