Get your greens and fruit in a glass with this nourishing yogurt smoothie Ellie Krieger, The Washington Post Dec. 31, 2020 FacebookTwitterEmail Green Smoothie With Yogurt, Pear and Ginger.Photo by Scott Suchman for the Washington Post. This green smoothie is not magical. It will not detoxify you (your liver, lungs and digestive system do that just fine) or cleanse you (food doesn't make you clean or dirty) or fulfill the overblown promises inevitably made about one food or another right after the New Year's ball drops. What this smoothie is, however, is a delicious and healthful breakfast or snack which can serve as a mental reset for a fresh start to the year.
