The most basic green diet smoothie consists of 1/2 teaspoon of stevia, 1/4 of a lemon, 2 to 3 tablespoons of flax oil, 3/4 to 1 pound of raw, washed greens and assorted fruit. The fruit portion can include 1 to 2 bananas, 1 to 2 cups of mixed frozen berries and any other fruit.
There are numerous green diet smoothie recipes available online. One recipe comes from Robyn Openshaw, author of "The Green Smoothies Diet: The Natural Program for Extraordinary Health," published in 2009 by Ulysses Press.
Green smoothie is a generic term that many foodies, health and lifestyle gurus have co-opted. Two such people are Jen Hansard and Jadah Sellner, authors of "The Simple Green Smoothies" book. At their website, SimpleGreenSmoothies.com, they offer multiple variations on the green diet smoothie, such as pre-workout green smoothie.
The pre-workout green smoothie contains 2 cups of fresh spinach, 2 cups of unsweetened almond milk, 1 banana, 1 large cored apple and 1/3 cup of rolled oats. One tablespoon of coconut oil and 1/2 teaspoon of ground cinnamon are the remaining ingredients. Blend the spinach and the almond milk until they are smooth, and then add the additional ingredients and blend.
Kimberly Snyder offers yet another green diet smoothie recipe, available at PopSugar.com. Blend 1 head of chopped romaine lettuce and 1 1/2 cups of water. Add 3 to 4 celery stalks, a medium bunch of spinach, 1 cored and chopped apple, 1 cored and chopped pear, and blend until smooth. Toss in 1/3 bunch each of cilantro and parsley, the juice of 1/2 of a lemon and 1 banana, and then blend to finish.
