Are banana and spinach a good combination?

This spinach and banana smoothie is a dynamite combination! Taste-wise, the natural sweetness of the banana masks the subtle flavor of the spinach. On its own, the natural sugars in ripe bananas give them a tropical, almost candy-like flavor. Combined with creamy yogurt and milk, you won’t even taste the spinach! Plus, combining spinach and banana also boosts the nutrient content—making this healthy green smoothie a rich source of fiber, vitamin C, magnesium, and potassium.

Spinach Banana Smoothie Ingredients & Substitutions

• Milk of Choice. Personally, I prefer to use soy milk for a bit of added sweetness, creaminess, and protein. But really, you can use any milk you like—dairy or nondairy!
• Spinach. This nutrient-packed leafy green is a must for this recipe. Of course, if you want to change up your greens from time to time, you could swap out the spinach and make a kale smoothie instead—or even an arugula smoothie!
• Banana. A frozen banana adds cool creaminess and sweetness to this low sugar smoothie, but you could also use a fresh banana instead. Either way, be sure to use a ripe banana for the sweetest flavor and best taste! You can also substitute with a different tropical fruit such as pineapple or mango, like in my tropical green make ahead smoothies.
• Yogurt of Choice. I love the thick, satisfying texture of a Greek yogurt smoothie—and it adds over 10g of protein to this recipe! You can also use regular yogurt, or use a nondairy yogurt to keep this spinach smoothie vegan.

Customization & Addition Ideas

• Fruit: In addition to banana (or as a substitute), there are loads of other fruits you could incorporate here. I’ve made this as a kiwi spinach banana smoothie by adding 2 peeled kiwis to the recipe, and it’s delicious! Or, try adding ½-1 cup of pineapple, mango, fresh or frozen berries, or sliced peaches.
• Vegetables: If you’re feeling adventurous, you can pack even more veggies into this green smoothie recipe. Whip up a refreshing cucumber smoothie, or even a broccoli smoothie!
• Nut Butter: This recipe is also delicious with 2-3 Tbsp of peanut butter blended in—or any nut butter that you like.
• Nuts & Seeds: For added nutrients and thickness, consider adding 1-2 Tbsp of chia seeds or ground flax, or nuts like almonds, walnuts, or cashews.
• Protein Powder: Of course, you can easily add a scoop of your favorite protein powder to this nutritious smoothie if desired!

Spinach Banana Smoothie Benefits

Truly, this spinach banana smoothie is like a sweet and sippable multivitamin. In combination, spinach and banana offer a healthy dose of dietary fiber. Plus, essential minerals like magnesium and potassium—which are involved in bone health, regulating blood pressure, and regulating mood and sleep.

On its own, spinach is an incredible source of vitamin K1: an essential nutrient for bone health that helps us absorb calcium from other foods. And, spinach also contains loads of immune-boosting vitamin C, vitamin A for healthy eyes and skin, and folate for cellular health DNA production. Plus, you’ll even get some calcium and iron.

On top of this, spinach and other leafy greens are incredible anti-inflammatory foods, rich in antioxidants that help reduce chronic inflammation and reverse free radical damage. In particular, spinach contains kaempferol—an antioxidant with powerful and well-studied anti-cancer effects! And don’t worry, blending spinach will NOT destroy the nutrients in your veggie smoothie. In its leafy form or blended form, spinach is one of the most nutritionally dense vegetables you can eat.
