Is it Good to Have a Smoothie for Breakfast?

A smoothie loaded with wholesome and nutritious ingredients is perfect for breakfast. That’s the key—you need fiber, protein and healthy fats to satisfy, as well as fill you up for hours.

Starting your day off with a smoothie helps get your digestive system moving, provides your body with clean, usable energy, and when that smoothie is balanced, helps you avoid the mid-morning sugar crash that comes with a carb-heavy breakfast option.

This banana oatmeal smoothie contains banana (shocker!), though the natural sugar from the banana is nicely balanced by the oatmeal and coconut milk to help the body slowly and evenly burn the carbs. #nosugarcrash

Can You Put Oatmeal in a Smoothie?

Yes, you can put oatmeal in a smoothie! You get all the benefits of a bowl of oatmeal, yet in a smoothie form. Oatmeal is loaded with fiber, which boosts the good bacteria in your gut. Whether you need an on-the-go breakfast or you crave a refreshing sippable morning meal, this delicious banana oatmeal smoothie is a great option.

Health Benefits of a Banana Oatmeal Smoothie

All of the wholesome ingredients in this oatmeal smoothie come together for a healthy and nutritious drink that both benefits your digestive system and boosts your heart health. Aside from the irresistible oatmeal cookie flavors, this banana oatmeal smoothie provides 3 key benefits:

Rich in fiber

While we all know fiber is a good thing, do we know if we’re getting enough fiber each day? According to the US Library of Medicine, only 5% of Americans are getting enough fiber each day. That’s why smoothies are such an important addition to your diet! Blended fruits and veggies give you a great fiber boost to aid in digestion, as well as help keep you regular.

One serving of my banana oatmeal smoothie gives you almost 20% of the recommended daily intake of fiber. So blend up and drink up–your body will thank you later.

A banana oatmeal smoothie with healthy fat

I know, fat isn’t always seen as a good thing. Yet hear me out; your body actually needs healthy fat in order to process your food properly. Without fat, the body does a poor job digesting food, converting carbs into energy, absorbing fat soluble nutrients like vitamins A, D, E, and K… which are vitally important. For a creamier smoothie use full-fat coconut milk. For a less creamy smoothie, use a homemade coconut milk, or one you can find in the refrigerated section of your local grocery store.

A naturally low sugar breakfast option

Many quick breakfast options are loaded with extra sugar. While that might make you feel a rush of morning energy, it’s just not sustainable for a busy day. Instead, this banana oatmeal sweet talker with a straw has less than 20 grams of sugar per serving, and balances out that sugar with healthy fat from the coconut milk + fiber from the oatmeal. These ingredients help the body break down the natural sugar, then turn it into usable energy.

Want to help your blood sugar even more? Use a plant-based protein powder, like my homemade protein powder, to give this smoothie an extra 10 grams of protein + 4 grams of healthy fat. This superfood blend helps keep you full longer, as well as provides more energy.

    I made this recipe this morning and I could not believe how full I was all morning. I have never added oatmeal to a smoothie before!! This was delicious and so easy to make as I had all the ingredients on hand. Thank you, Jen for all these wonderful recipes.

    I made this smoothie with 2 cups of oat milk, in place of the rolled oats and coconut milk, then followed the rest of the recipe for two. We loved it!! I can’t say a bad thing about it.
    It was our lunch smoothie as we did the 10 smoothies for lunch each day, No bread, cheese or deli meat!
    We are so looking forward to the soups! Some are so new to us, it will be an adventure.
    Thank you Jen and staff for providing a great website with all of the amazing drinks!!!

      Wow awesome love it today this morning breakfast my favorite Oatmeal Frozen Banana Raw Honey cinnamon coconut milk simple green smoothie protein powder boost add little chia seed yummy feel good healthy love it yes

  4. Loved this smoothie, but what about soaking the oats beforehand? The same questions goes for you oat milk recipe, which I am dying to try.

    1. If you’re up for it, soaking the oats for several hours before blending in this smoothie (or making oat milk) is a great idea! It reduces the phytic acid and the starchiness of the oats, allowing for better absorption of the nutrients in them.

    I added raspberries in this when I made it, and it was SO good! A filling breakfast recipe.

    Loved this and it’s so versatile! I tried adding a little kale and some frozen blueberries. The berries seemed to hide the kale color and flavor and it tasted kind of like a cross between blueberry muffins and banana bread

    1. Oh! And pulsing the oats a few times in the blender before adding everything else made it turn out more smooth for me:)

  7. I am wondering about the use of coconut milk or coconut oil.. I have heard many people say there is too much fat in it. What say you Jen?

    1. We are def all about healthy fats here at SGS! We know that they help our bodies absorb vitamins, help our skin glow and stay hydrated, help to keep us from overeating and even help our brain work correctly. We’d suggest reading more about it so you know for sure what’s best for your body. You can start with our article :: Healthy Fats – What Are They + How to Use Them which contains links to additional research from places like the National Institutes of Health.

    This was very good! Thank you for sharing your recipes! I didn’t have any coconut milk, I used oat milk instead, turned out very creamy and delicious!

    I used full fat coconut for a creamier smoothie, but the coconut flavor and texture overpowered the oats and bananas :/ I would recommend using a lighter coconut milk. I’m planning on trying it again and hope for a better outcome!

    1. Thanks for the feedback Anna! Def let us know what you think with your next blend!
