Some tips for juicing and/or blending:
To prevent excess sugars, limit the fruit in both juices and smoothies to 1-2 servings per drink (i.e. ½ cup to 1 cup fruit)
Green veggies like kale, spinach, parsley, and cabbage surprisingly do not taste very intense in smoothies or juice, so load up on those!
Citrus, lime juice in particular, can help to cut out any bitter taste from vegetables (remember to remove the peels)
When juicing, high water content vegetables like cucumbers and celery will help to add volume and nutrients
When blending smoothies, add regular or coconut water to make it less pulpy
You get what you pay for when buying a juicer or a blender: the current products claiming to have benefits over other standard blenders tend to have higher horsepower
