27 Aug 2018 --- US restaurant Jamba Juice is facing a class action lawsuit filed in federal court for marketing its smoothies as containing “whole fruits and vegetables,” when they largely consist of unadvertised, less nutritious ingredients such as juices from concentrate, The Center for Science in the Public Interest (CSPI) reports. Despite using statements like “Jamba blends whole fruits & veggies” and “Whole fruit! That’s how we blend” on marketing materials, Jamba Juice uses large quantities of juice blends, sherbet and other non-whole fruit and non-whole-vegetable ingredients in its smoothies, according to the complaint.
