Fiber Smoothie Cubes

I get asked all the time about how to increase fiber in green smoothie recipes. You can only add so much spinach or kale before you’re over it. So I thought, “Why don’t we make fiber smoothie cubes?” So these fun + simple frozen smoothie cubes are loaded with fiber and protein to fuel your day and keep you regular.

How To Use Fiber Smoothie Cubes

The other recipes in my smoothie cubes series include directions for substituting a portion of fruit in a recipe with the cubes. This one is a little different in that it is designed to be used as a replacement for all the fruit in the recipe and blended with your choice of liquid and leafy greens, if desired. If you need a new blender, I like these smoothie blenders the best.

You can add it to a fruit smoothies, tropical smoothies, weight loss smoothies, or green smoothies, but it will do the job by itself as a meal replacement. Add a banana or another pitted date for added sweetness. If you’re new to smoothies, check out my how to make a smoothie guide for more tips.

Ingredients You’ll Need

• Almond milk: The smooth, neutral base that helps everything blend easily. You can make almond milk or pick from almond milk brands that me and my team have vetted.
• Chia seeds: Create the gel texture and deliver soluble fiber for fullness.
• Hemp hearts: Add plant-based protein and healthy fats without changing the flavor.
• Psyllium husk powder: The digestive powerhouse that boosts fiber and gut support.
• Medjool dates: One of my favorite natural sweeteners that also adds trace minerals to the cubes.
• Cacao powder: Gives a rich chocolate flavor with antioxidants, no added sugar.

This fiber smoothie cubes recipe below isn’t just an excuse for a chocolate fix. These cubes are full of fiber + protein, 2 vitally important nutrients for your body. Let’s learn more!

The Importance of Fiber and Regularity

Staying “regular” is a top priority for most of us, or at least it should be! Fiber works like little scrubbing brushes on the inside of the digestive tract. It adds bulk and keeps things moving along when in proper balance. Regularity is a sign that the body is working like it’s supposed to, using the nutrients consumed and ridding itself of waste or excess.

Please note that “regularity” is the ideal situation.

There are a lot of conditions, medications, and situations where regularity is really difficult to achieve. See your health practitioner for specific recommendations if constipation, diarrhea or bloating, as well as excess gas are an ongoing problem for you.

Another trick to staying regular is to make sure you’re consuming enough food, preferably moderately high or high in fiber, at regular intervals. Skipping meals or eating too little (such as with fasting, dieting, calorie-dense but low-volume foods) can contribute to irregularity. In any case, it is super important to make sure your body is getting enough fiber and that your digestive tract is humming along.

What Else Can I Add to My Smoothie for Fiber?

Plants are the only source of fiber. Chicken, beef, fish, pork, eggs, and other animal products contain 0% fiber. Plants are made up almost entirely of fiber along with water, fats, and starches. Fiber itself is essentially just a carbohydrate. Dietary fiber cannot be broken down by digestive enzymes.

Here are some ways to add fiber into your smoothies:

• dark leafy green vegetables
• whole fruits (not juice)
• psyllium husk powder
• hemp powder
• banana
• chia seeds
• fiber smoothie cubes
• pears
• strawberries
• avocado
• apple
• raspberries

More Smoothie Cube Recipes

Each one of these recipes is designed to be frozen in an ice cube tray, then stored in the freezer until you’re ready for a plant powered boost. I usually keep 2 or 3 different kinds of smoothie cubes on hand, so that I don’t need to rush around finding ingredients at a moment’s notice. Here are my fav smoothie cubes:

• Antioxidant smoothie cubes– Use these when in need of a beauty boost. Just replace the fruit in your next smoothie with 4 cubes.
• Alkaline veggie smoothie cubes– These provide a green veggie boost. Replace the leafy greens in your next smoothie with 4 of these cubes.
• Electrolyte smoothie cubes– When you think of these cubes, think of an energy boost. No matter the workout, big or small, you need to be replacing your electrolytes. These cubes do just that!
• Coconut milk smoothie cubes– These are healthy fat bombs of goodness. Add some of these cubes to your next smoothie, and watch your hair shine, as well as your skin.
• Anti inflammatory cubes– Just like the name suggests, these blender bombs are loaded with veggies that help soothe inflammation in the body. These can easily be added to any smoothie (tropical flavors are the most complimentary!).

Instructions 

• Place 2 cups almond milk and chia seeds in a bowl and stir well. Let sit for 10-15 minutes.
• Pour chia gel into a blender jar. Add the other ingredients. Puree until smooth. Add a little more liquid, if needed, for easier blending. The mixture will be very thick with a pudding-like texture.
• Transfer the mixture to two standard, 16-well ice cube trays. It’s okay if the mixture overflows the wells a bit, as long as it doesn’t go over the sides of the trays themselves.
• Place trays in freezer and freeze overnight, or until completely solid. Pop the cubes out of the trays and place in an airtight, freezer-safe container. Store in freezer for up to 2 weeks, or a little longer if using a deep freezer.
• To use, add 1 cup liquid and 2 cups your choice of leafy greens to a blender, add 4 fiber cubes. Blend until smooth. If not sweet enough, add part of or one whole ripe banana, or a little maple syrup, to taste.
