As a Canadian dietitian who works and lives in the United States, I like to keep up with health policy in both countries. So, I was quite interested to see that Health Canada, the governmental agency responsible for public health, is charting a new course when it comes to dietary advice, particularly in the area of sugar substitutes. It's a track that sharply diverges from the one the United States is on. 我是一名工作在美国，生活也在美国的加拿大营养师。我喜欢及时跟进两国的健康政策。所以，当加拿大卫生部（负责公共卫生的政府组织）制定了新的膳食指南，尤其是针对甜味剂领域的指南时，我非常感兴趣。这条指南与美国的相关指南截然相反。 In a significant departure from the past as well as from the U.S. approach, Canada's new food and dietary guidelines, released this year, say zero-calorie or low-calorie sugar substitutes are neither necessary nor helpful. "Sugar substitutes do not need to be consumed to reduce the intake of free sugars," the guidelines say, adding that, because "there are no well-established health benefits associated with the intake of sweeteners, nutritious foods and beverages that are unsweetened should be promoted instead." 于今年发布的加拿大最新版膳食指南与去年的旧版以及美国的膳食指南存在很大的不同，其表示，零卡路里或低卡路里的甜味剂既不必要也没有帮助。"没必要摄入甜味剂来降低游离糖的摄入量，"该指南表示，并补充写道，因为"摄入甜味剂并没有明显的健康益处，我们应该提倡不加糖的营养食物和饮料。" |
