The Best 15 High-Fiber Foods (And Hacks to Eat More)

Surprisingly, most people don’t eat nearly enough dietary fiber. To the tune of eating only 39 to 60% of the recommended daily intake (which is something between 25 - 38 grams per day)[*]. The result? You might be missing out on some serious digestive benefits, or worse, have a  higher risk for Type 2 diabetes, cardiovascular disease, or some cancers[*].

So, eating fiber should (and is!) part of a healthy diet. How does your current diet stack up?

    What Is Fiber?

    Fiber is simply the indigestible elements of plant-based food (e.g., cellulose, resistant starch, lignins, and other stuff)[*]. Unlike most food we eat, fiber passes through our digestive system pretty much intake because we don’t have the enzymes or bacteria needed to digest it. Well, that’s not entirely true.

    Humans use some elements of fiber after it’s fermented inside of us. Yup, the brewing happens in the small intestine by yeast, after which the fibrous material gets eaten by good bacteria to promote gut health. Because around 70% of the immune system resides in the gastrointestinal tract[*], eating sufficient (and good quality) fiber can have a huge impact on your health.

    Types of Fiber

    Fiber is fiber, right? No so fast.

    Fiber comes in two main forms: soluble and insoluble. While most plant-based foods contain a combination of both fibers, ratios can vary dramatically. Both can improve digestion and boost health, but they each work a little differently.

    Soluble Fiber

    Picture cereal that's been left to stand in moisture for a while. What happens? The cereal expands and becomes a mushy pulp. This is pretty much how soluble fiber works too.

    On its journey through the digestive tract, soluble fiber absorbs water and expands, becoming soft and viscous. Because of its thick consistency, soluble fiber moves through the digestive system at a slower rate. Oats, peas, barley, beans, avocados, apples, blueberries, and psyllium are all great sources of soluble fiber.

    Insoluble Fiber

    Often referred to as roughage, insoluble fiber is found mainly in the skins, peels, and seeds of plants. Unlike soluble fiber, insoluble fiber retains most of its original shape and texture. Because of its rough and bulky nature, insoluble fiber collects waste and physically pushes out other partially digested foods, speeding up the elimination process. An easy way to grasp the action of insoluble fiber is to think of it as broom sweeping your digestive tract clean.  Some excellent sources of insoluble fiber include celery, wheat bran, beans, legumes, brown rice, green beans, and root vegetables.

    Benefits of Eating High-Fiber Foods

    You’ve read about it in health magazines, heard it from doctors, and chances are your mother told you too: fiber is a vital part of any diet. But while it’s easy to overlook fiber until digestive dysfunction rears its ugly head, research shows that the benefits are far more comprehensive than most people realize[*].

    Here are a few reasons why you should be filling up on fiber:

  • Fiber aids digestion. Soluble fiber softens and expands stool, making it easier to pass. Insoluble fiber, on the other hand, creates desirable bulk or volume in the digestive tract and therefore promotes speedier and more regular elimination.
  • Fiber boosts gut health. Aside from clearing out waste and toxins, soluble fiber also boosts the production of beneficial bacteria in the digestive tract, decreasing the risk of gastrointestinal disease[*].
  • Fiber reduces the risk of colon cancer. Studies show that fiber binds carcinogens and other potentially harmful impurities, and may help combat and prevent colon cancer[*].
  • Fiber can help with weight loss. Because soluble fiber adds bulk and moves through the digestive tract slowly, it helps keep hunger pangs at bay. It’s also been shown to decrease the absorption of macronutrients and fats[*]. Insoluble fiber also helps you feel fuller, and by forcing waste out faster, it can reduce bloating.
  • Fiber reduces the risk and severity of type 2 diabetes. Fiber, especially soluble sources, can slow the rate of sugar absorption, preventing insulin spikes and stabilizing blood glucose levels[*].
  • Another area in which soluble fiber shines is in reducing the absorption of harmful low-density lipoprotein cholesterol (LDL)[*].
  • Fiber improves heart health. Much of fiber's role in improving cardiovascular function stems from soluble fiber's ability to decrease the absorption of cholesterol, but research indicates that insoluble fiber also plays a role in heart health, so be sure to fill up on both[*].

    Easy Hacks To Eat More Fiber

    Need more fiber, but just can't stomach the thought of downing another whole fruit or vegetable? Don't fret. These sneaky tips can help you achieve your nutritional goals as painlessly as possible.

    Hop on the Hummus Bandwagon

    Hummus is creamy, delicious, and packed with protein, heart-healthy unsaturated fats, and fiber.

    • Spread two tablespoons on your next sandwich for a 1.2 gram fiber boost (psst! — using whole wheat bread will add another 5.9 grams of fiber to your meal).
    • Or, use half a cup as a veggie or whole grain cracker dip to score 4.9 grams of fiber while you snack.

    Chow Down on Chia Seeds

    Proof that dynamite comes in small packages, chia seeds are rich in omega 3 fatty acids and provide a whopping 5 grams of fiber per tablespoon.

    • Mix some in with your smoothie, morning cereal, or yogurt. Just be prepared for a thick texture — chia seeds suck up moisture like crazy and produce a gel-like texture.
    • Their high rate of absorbency and unique texture also makes them ideal for puddings. For an easy, high-fiber dessert, snack, or breakfast, grab a mason jar and mix six tablespoons of chia seeds with two cups of almond milk, half a teaspoon of vanilla essence, and a sweetener of your choice. Stir well and leave to set for a couple of hours or overnight.

    Add Oats to Everything

    If you've only been eating oats for breakfast, you're missing out. Think out of the box and add oats wherever you can — you'll be upping your fiber intake and saving some cash at the same time.

    • Making meatloaf or burgers for dinner? Add a quarter cup of oats for every 2lbs of ground beef.
    • Toss a couple of tablespoons of oats into a smoothie for a bit of texture and a thicker consistency.
    • Oatmeal cookies are always a hit, but you can incorporate oats into a variety of other baked goods as well, so get online and root out those recipes.

    Drink Your Fruits and Veggies

    Juices are great, but when it comes to filling up on fiber, whole fruit and veg smoothies have a definite edge.

    • Mix up a variety of fruits and veggies for a blend of fiber and nutrients.
    • Add even more fiber by sneaking in a couple of tablespoons of oats or ground flaxseed (one tablespoon of ground flaxseed contains 2.2 grams of fiber).

    Snack on Popcorn

    Low in calories and rich in antioxidants, popcorn makes a great fiber-filled snack when you're craving a bit of a crunch (plus popcorn is keto-friendly..ish).

    • Three cups of air-popped popcorn packs 3.5 grams of fiber and only 93 calories.

    Half Is Better than Nothing

    Making the switch to fiber-filled pasta and rice can take some getting used to, but you don't have to do it all at once.

    • Try substituting half of your regular pasta for whole wheat pasta and mix the two together for a gentler transition.
    • The same applies to rice. Rather than taking an all or nothing approach, mix your regular rice with brown rice to help you get accustomed to the deeper flavor and textures of fiber-rich variants.

    And Don't Forget...

    Adding more fiber to your diet can help you stay regular, but be sure to drink plenty of water to keep things moving along. Without adequate hydration, too much fiber can have the opposite effect, causing your digestive system to become backed up and bloated.
