There are hundreds of reasons to drink smoothies: they're a breeze to make, are high in fiber, and loaded with vitamins and nutrients – if you use the right ingredients. Smoothies can also be sneakily high in calories and packed with sugar (see, Jamba Juice).

And while you're at it, toss in a spoonful of chia seeds, swap regular milk for coconut or almond milk, and sift in a cup of hemp granola. Here, are 19 great recipes to start.
