Sometimes, the natural sweetness of fruit is not enough to disguise the rather bitter taste of leafy green vegetables in a green smoothie recipe. Because the point of a green smoothie recipe is to provide you with a healthy and nutritious snack, you will want to avoid the use of plain old white sugar. However, there are a number of natural alternatives that you can use to sweeten your green smoothie recipe.
Some of your options will include honey, maple syrup, stevia, and agave nectar. It should be noted that while all natural, agave nectar does tend to be rather high in natural sugars, so it should be avoided by diabetics or those with blood sugar problems. Stevia and dark honey tend to be the most popular options for sweetening a green smoothie recipe, but it is important to ensure that these ingredients are organic and natural.
Most experts recommended starting off with 1-2 tablespoons of the natural sweetener in your green smoothie recipe, and then sweeten to taste as needed.
