7 Clever Ways To Get More Fiber In Your Smoothies, According To Experts

It's no secret that including fiber in your diet is essential for healthy digestion, but did you know that most people aren't getting enough? While our daily fiber needs1 per the National Academies range between 21 and 38 grams, depending on age and gender, the average American only eats about 16 grams2. (In fact, only 5% of the population is estimated to be meeting their daily fiber needs!)

That's definitely a shame, considering getting adequate fiber (both soluble and insoluble) in your meals will not only keep you feeling satiated, but it can also directly aid digestive regularity, support a healthy gut microbiome, and even maintain healthy blood sugar levels.

So, what's a simple way to increase your daily fiber intake? Look no further than your daily smoothie.

Your go-to smoothie is likely already rich in an array of fruits and vegetables, but if you're low on fiber (and odds are, most of us have a fiber deficit), this is one of the easiest meals to modify for a quick boost. Not sure which ingredients will do the trick?

Experts share some staples to consider adding to your morning drink to optimize digestion and fuel your body throughout the day:

There are a number of different forms of fiber to include in your diet for an array of benefits, including one found in a much-loved grain: "Uncooked oats3 [are a] great source of the fiber beta-glucan," says Julie Stefanski, RDN, CSSD, and spokesperson for the Academy of Nutrition and Dietetics.

FYI: Beta-glucans are a type of fiber linked to an array of benefits, including gut, heart, and immune health—plus they can help support healthy blood sugar levels (more on the bioactive plant compound here).

As for the oats themselves, "not only will they pack in fiber, they will also add some texture [to your smoothie], and make it more filling," adds Valerie Agyeman, R.D., and host of the Flourish Heights podcast.

If you're craving a creamier smoothie that's loaded with health benefits, turning to avocado as a source of fiber4 may be your best bet. Avocado is "high in fiber, plus a beneficial monounsaturated fat," working to promote healthy blood pressure levels and cardiovascular wellness, all while keeping you regular, explains Stefanski.

Avocado also adds very little flavor to a smoothie, simply helping to make the blend a richer, more delicious treat.

Chia seeds are especially useful for increasing the amount of fiber5 in your go-to smoothie without changing the taste at all. "Two tablespoons of chia seeds have 8 grams of insoluble fiber," explains bariatrics dietitian Carrie Kirkland, R.D., L.D. This means that chia seeds can be particularly great for keeping you full for longer and making your smoothie all the more satisfying.

What's more, adding chia seeds can help thicken your smoothie and make it even more hydrating!

Often found in green smoothies, spinach6 is a powerful addition to your drink: It significantly bulks up your beverage, without really affecting the taste. "Baby spinach is a source of fiber that is also very high in B vitamins and phytochemicals," notes Stefanski. Other key micro- and phytonutrients in the leafy green include beta-carotene (aka vitamin A), vitamin K1, and the carotenoid lutein7—making spinach a worthy addition to any blend.

Berries are common additions to smoothies for their delicious flavor—but, what's more, they can provide an instant boost of both fiber and antioxidants8. "Berries come in so many varieties and can really increase the fiber content in your smoothie, and it works as a natural sweetener. Just 1 cup of blueberries or strawberries will increase the fiber content by 4 grams," says Agyeman. From strawberries to raspberries and blackberries, try out any combination of flavors to take your smoothie to the next level.

Calling all chocolate lovers: Adding some cocoa powder to your smoothie will not only make it taste like a chocolate milkshake but also level up its nutritional perks. "Cocoa powder9 [is both a] source of fiber and antioxidants," says Stefanski.

In fact, on a mindbodygreen podcast episode, nutritional psychiatrist Drew Ramsey, M.D., shared how he actually encourages eating chocolate for breakfast, due to its antioxidant properties (more on that here).

Not to mention, it will elevate the flavor of just about any smoothie formula. For a delicious combination (plus a nice balance of protein, carbs, and healthy fats), try pairing it with a banana and a scoop of peanut butter.
