Coffee Smoothie Health Benefits
Enhances Feeling of Fullness
Bananas are rich sources of fiber, a nutrient that reduces hunger.
It increases satiety, or fullness, because it’s digested slowly. This means it stays in the body for a long time.
Hemp seeds also have some protein, which contributes to satiety.
Boosts Energy
Feeling hungry can make you feel tired and sluggish. But thanks to the satiating effect of bananas and hemp seeds, this smoothie can give you a boost.
Also, coffee contains caffeine. This is a substance that stimulates the body and mind, giving you energy.
Supports Digestion
Getting enough fiber is key for healthy digestion. It keeps you regular and reduces the risk of digestive issues.
This smoothie is a good source of fiber thanks to the banana.
Manages Cholesterol Levels
Banana, which is used in this smoothie, is a heart-healthy food.
It has soluble fiber, a type of fiber that reduces high cholesterol.
High cholesterol can increase the risk of heart disease, so it’s important to control it.
Reduces Inflammation
Over time, too much inflammation can lead to disease. Examples include heart disease and diabetes.
Hemp seeds can help lower the risk. They’re rich in omega-3 fatty acids, which are anti-inflammatory in the body.

Optional Add-Ins
Extracts
If you want to add extra flavor without changing the smoothie’s texture, use extracts.
This smoothie would taste great with almond extract or vanilla extract.
Use ½ teaspoon per smoothie.
Butters
Coffee and nutty flavors are delicious together. To enjoy the combination in this smoothie, add 1 or 2 tablespoons of nut or seed butter.
Tasty options include peanut butter, almond butter, and sunflower seed butter.
Aside from adding flavor, these ingredients have anti-inflammatory fats and a bit of protein.
Protein powder
To bulk up your smoothie and make it more filling, add protein powder. You can use chocolate, vanilla, or unflavored protein powder.
The add-in will turn your smoothie into a post-workout snack. That’s because protein power is a supplement that supports exercise recovery.
Another option is collagen powder, which is good for skin health.
Blender Tips
Chop fruits before freezing.
Before making a coffee smoothie, you’ll need to freeze a banana first.
Never put a whole frozen banana in your blender. Instead, slice the banana into coins or chunks first.
The chunks can be about the size of an apple wedge if you have a more powerful blender.
Begin with liquids.
The secret to a perfect smoothie is to load ingredients in a certain order.
Start with lightest and softest ingredients. This includes liquids, liquid sweeteners, and add-ins like powders and nut butters.
When you turn on the blender, these ingredients will pull everything else toward the blades.
After the light ingredients, add leafy greens and fresh fruit. Hard and heavy ingredients, like ice and frozen fruit, should go in last.
Avoid blending on low for too long.
Blend on high speed for most of the recipe. This will keep your motor cool.
If you blend on low for too long, the motor will overheat.
Rotate ingredients with a tamper.
A tamper is a tool that’s included with most blender models.
It’s designed to be inserted through the lid while the blades are moving. Move the tamper around the container, in a circle, hitting all 4 sides.
This allows you to move ingredients toward the blades, helping remove air pockets.
Use a blade scraper.
An easy way to avoid wasting smoothie is to use a
This tool lets you remove leftover smoothie underneath the blender’s blades.
You can also use a mini spatula.
