For me, green smoothies are all about packing good stuff into my diet, things that I might not get around to eating otherwise. Dark, leafy greens such as kale, spinach, swiss chard and collard greens are loaded with vitamins A and C, while also being very high in calcium and iron, not to mention fiber, phytonutrients, and digestion-enhancing enzymes. Fruits and berries (common smoothie ingredients) are also great for you, but I personally never have a hard time working them into my diet. It’s easy to toss back a few handfuls of blueberries, less easy to throw down a couple cups of kale.
That said, green smoothie making isn't as straight-forward as fruit smoothie making. Throw fruit in a blender and, 9 times out of 10, you’re going to be pleased with the results. Throw lettuce in a blender, however, and you might end up wondering why you’re choking down a pureed salad.
It helps to have a couple of tips.
