Starbucks faces a US consumer lawsuit over the marketing of eight protein drinks, VietnamPlus reported. The plaintiffs argue that a “sugar-free” message could mislead customers because the drinks still contain lactose from milk, and they are seeking compensation. Starbucks rejects the allegations, saying ingredients and nutrition information are publicly available and describing the products as having no added sugar. The report sets out the competing positions. It does not establish a court finding of wrongdoing or a specified damages award.
