The answer is, it depends on what you add to them! If you order a smoothie at a restaurant, it's likely packed with added fruit juices and syrups to make it sweeter. Fruit juices and syrups like agave, honey or maple syrup are all just different forms of added sugar and are not needed in a smoothie - since fresh fruit is already sweet! If you use whole food based ingredients, no added sugar, and nothing processed or dessert-like, then yes, banana peach smoothies are super healthy for you. This peach and banana smoothie recipe is healthy for a few reasons: 1) No Added Sugar: This smoothie tastes like a sweet milkshake but it has no sugar added! All of the sweetness comes directly from the fresh fruit, so you can enjoy this breakfast totally guilt free. 2) Vitamins And Minerals: Bananas are rich in b vitamins and potassium, and peaches and mangoes both contain a high amount of vitamin a and vitamin c, and all 3 fruits are high in dietary fiber! 3) Heart Healthy: Peaches are a heart-healthy fruit - studies have shown that they may have the ability to lower blood pressure, stabilize your blood sugar and help manage cholesterol levels.
