Core Viewpoint - The rising popularity of kale drinks in tea shops is driven by consumer demand for healthier options, but their actual effectiveness for weight loss is questionable [1][3][4]. Consumer Confusion - Many consumers believe that kale drinks can aid in weight loss due to marketing terms like "light burden" and "slim" used by various tea brands [1][3]. - The price of kale drinks ranges from 20 to 30 yuan per cup, making them more expensive than traditional tea options [2][7]. Nutritional Analysis - Kale itself does not have direct weight loss effects, and the drinks often contain high sugar and calorie content due to added fruits and sweeteners [3][4][8]. - For example, a 500ml kale drink from Nayuki contains 166.5 calories, equivalent to a bowl of rice, while avocado and coconut milk in other drinks significantly increase their caloric content [4][9]. Legal Opinions - Legal experts suggest that companies should avoid misleading terms like "slim" and must accurately label ingredients and caloric content to comply with consumer protection laws [5][10]. - If companies misrepresent the health benefits of kale drinks, they may face legal consequences, including potential claims for damages [10][11].
