I’ve always been curious about the composition of my beloved brew. What type of Fiber is in coffee? Recently, a new study caught my attention, shedding light on an intriguing aspect of coffee that’s often overlooked: the dietary fiber in brewed coffee. Yes, you read that right – Cafes contain more than just caffeine and flavor.

This discovery has significant implications for coffee lovers like me, and it’s essential to understand the type of fiber found in coffee. Join me as we explore this fascinating news for coffee lovers and uncover the benefits of adding fiber from different coffee beans to our daily ritual.

What Type of Fiber is in Coffee?

As a coffee expert and roaster for over a decade, I’m often asked about the nutritional coffee’s value, specifically the amount of fiber in it. Many people don’t realize that coffee types including espresso and even instant coffee, contain a small amount of certain beneficial fibers.

What Type of Fiber is in Coffee?

In this article, I’ll break down the different types of fiber found in it and explain how they contribute to its health benefits. Recent research published in the Journal of Agricultural and Food Chemistry even reveals that there’s more dietary fiber in coffee than orange juice.

While Cafe is of course not a significant source of dietary fiber compared to foods like fruits, vegetables, and whole grains, the fiber it does contain adds up, especially for those who drink coffee as part of their daily intake. Let’s analyze the fiber makeup and delve deeper into its dietary fiber content.

Soluble Fiber

The primary type of fiber in brewed Cafes is soluble dietary fiber, also known as viscous or dietary soluble fiber.

Soluble fibers dissolve in water and become gel-like and viscous. When coffee grounds are brewed, these fibers soluble are extracted into the final drink.

Fulgencio Saura-Calixto, a leading researcher in the agricultural and food chemistry field, highlighted that up to 1.5 grams of dietary fiber type can be present in it. That’s about 0.2-0.4 grams of fiber per 8oz cup.

Soluble fibers like those found in coffee provide benefits like:

  • Improved cholesterol levels
  • Healthy blood sugar regulation
  • Delayed stomach emptying

The small amount of soluble dietary fiber adds up to a meaningful amount over multiple daily cups of coffee.

Insoluble Fiber

The other type of fiber comes from the insoluble fiber left intact in the coffee beans after brewing. This is notable because many don’t realize that it’s not just the liquid; the grounds themselves contain beneficial components.

Cellulose and lignin make up most of the insoluble fibers locked inside the grounds. Prebiotics like inulin, often highlighted by food scientists at the National Research Council in Madrid, are also contained in the insoluble fraction. However, prebiotics only provide benefits if directly consumed.

Comparison with Other Beverages

It’s a well-discussed topic in nutrition communities how coffee stacks up against other common beverages. While it’s well known that coffee beans offer a myriad of health benefits, how does coffee fare against, say, orange juice?

Comparison with Other Beverages

A recent study by Elena Díaz-Rubio shed some light on this. According to their findings, coffee, especially when compared to orange juice, might contain more soluble dietary fiber.

Interestingly, instant coffee contained a significant amount of fiber, and the study also looked into other coffee types, revealing that espresso coffee, just like vanilla-flavored coffee, stood out in terms of content in fiber. This demonstrates how different coffee preparation methods can impact nutritional composition, much like how Coffee Bean carefully calibrates the ratio of matcha types to control the flavor profile of their signature coffee bean matcha type.

Chlorogenic Acids

While not a traditional fiber, coffee’s phenolic chlorogenic acids provide similar benefits to fibers that are soluble.

Caffeic acid and other chlorogenic acids regulate blood sugar, lower cholesterol, and promote gut health. It’s particularly beneficial for those with type 2 diabetes. Around 30% of chlorogenic acids are extracted from the grounds into the final brewed coffee.

Fiber Content Differences

The actual content in fiber of coffee can vary slightly depending on:

  • Bean type – Robusta beans contain more fiber than Arabica
  • Roast level – Darker roasts break down more fiber
  • Grind size – Finer grinds extract more fiber
  • Brew method – Drip coffee extracts the most fiber

But these differences amount to hundredsths of a gram. Overall fiber that is soluble makes up ~1% of all brewed coffee on average.

Benefits of Daily Coffee Consumption

A daily coffee routine doesn’t just wake you up. Consuming cups of the best coffee types a day could inch you closer to your recommended fiber intake. The daily recommended amount of fiber is about 25 grams for an average adult.

When it comes to the best coffee types for dietary fiber, look for whole bean coffees as they retain more fiber than ground varieties. Also choose high-quality Arabica beans, which contain more fiber than Robusta. Consuming 1-2 cups a day of the best coffee types like high-fiber light roasted Arabica can help support overall health.

Benefits of Daily Coffee Consumption

While coffee is not a primary source of fiber, those who drink coffee daily can still add a significant amount to their fiber intake. For those looking to increase their fiber per day, adding coffee to their diet can be beneficial.


  • The fiber in brewed coffee mainly consists of soluble fibers like galactomannans.
  • This accounts for 0.2-0.4g per cup, which adds up over daily consumption.
  • Soluble fiber provides benefits like healthy cholesterol and blood sugar levels.
  • Insoluble fibers are largely filtered out by brewing but provide little benefit.
  • Chlorogenic acids function similarly to soluble fiber while conferring other benefits.
  • More finely ground and darker roasted cafes contain marginally less fiber.
  • Consider the fiber content a nice bonus to the many other nutrients in coffee.


Coffee and tea both contain fiber, but how much more so?

Both coffee and tea provide fibers soluble. But tea contains a bit more – green tea has ~2g fiber per 8oz cup versus 0.2-0.4g for coffee.

Is the coffee’s fiber good for weight loss?

The small amount of fiber soluble can aid weight loss by promoting feelings of fullness and regulating blood sugar and metabolism. But coffee’s caffeine is likely more responsible for the weight loss benefits.

Is the coffee’s fiber good for your gut?

The fiber soluble and chlorogenic acids in coffee function as prebiotics supporting gut bacteria and healthy digestion. But other drinks like kombucha contain much higher prebiotic fiber levels.

Does coffee have as much fiber as vegetables?

Not even close. One cup of broccoli for example provides over 5g of fiber. Coffee’s 0.4g pales in comparison to high-fiber plant foods, though every little bit helps.

Do you get more fiber from caffeinated or decaf coffee?

Typically caffeinated. Decaf coffee loses some fiber soluble during the decaffeination process. But the difference is quite small.

In conclusion, I hope this has helped explain the complete fiber profile of coffee and its contributions to your diet.

While coffee isn’t a primary source of fiber, its contribution to one’s diet is noteworthy. The fibers soluble and insoluble, along with the chlorogenic acids, make it a beverage worth incorporating into your daily routine.
