High Fiber Foods List - We Analyzed 237 Fiber Rich Foods
This is the ultimate fiber foods list! Our research team spent 100+ hours researching the exact fiber content of everything from apples to bananas and right through to oatmeal and even spinach. Finally, you can see how much fiber you get when eating your favorite foods. Best of all, we show you the fiber amount per serving, so you can easily compare foods and work out which are best for you. (And if you're a big fiber geek like us, you can also finally find out the soluble vs insoluble fiber content of each food!)

Low vs medium vs high fiber
Unfortunately most fiber food lists just give you the amount of fiber per 100 grams. But that's not very useful. After all, who's eating 100 grams of onions in a sitting?
So as you'll see in our fiber foods chart below, we focused on looking at how much fiber you get per typical serving of that food. For example, 1 teaspoon of ginger or 1 medium apple or 4 prunes etc.
Then to make it even better, we decided to break the foods across 3 categories, which differentiated which fiber-rich foods were delivering the most fiber per serving.
So we created 3 categories - being low, medium and high fiber. And here's how we classify each of them:
- Low fiber food - has 0 to 2 grams of fiber per serving size. e.g. 1 cup of watermelon has 0.61 grams of fiber. Now, just because these foods are not super high in fiber, doesn't mean we should neglect them. Especially, since many of them deliver very potent forms of fiber, such as prebiotic fiber.
- Medium fiber food - has 2 to 3 grams of fiber per serving size. e.g. 4 prunes deliver 2.7 grams of fiber. These are solid fiber-rich foods to focus on adding to your diet at all meals.
- High fiber food - has 3 or more grams of fiber per serving size. e.g. 1 medium apple has 4.37 grams of fiber. This last category of course, includes all the most popular foods high in fiber - and you will be amazed at how much fiber they pack per serving. For examples, in just 1/2 a cup of cooked black beans you'll get a whopping 7.48 grams of fiber!
How much fiber in...

1. Vegetables
34 low fiber vegetables
Although these vegetables are 'low fiber', we need to realize that many of them contain very potent 'prebiotic' fibers, which can have a hugely beneficial impact on the gut, even in small amounts.
A great example would be onions. As you can see below it only delivers around a third of a gram of fiber (for 1/8 cup). But this fiber is loaded with fructan prebiotic fiber - which can feed our good bacteria.
7 medium fiber vegetables
Here we see some heavier fiber hitters of the vegetable world. And it is quite surprising to see some of these not actually on the high fiber list. For example, cauliflower is often thought of as a fiber king. But as we can see below, it only delivers just over 2 grams of fiber (for 1 cup serve).
13 high fiber vegetables
Say hello to the most fiber rich vegetables in the world! We've got some obvious entrants on this list like potatoes and other root vegetables. But we also have some surprising results, like seeing over 3 grams of fiber from asparagus!
