请注意,快餐爱好者们。如果新年伊始还不足以让您改变饮食习惯,那么新的研究结果可能会让您改变。一项长期研究明确地将快餐消费与肥胖症和 2 型糖尿病联系起来。

在最新一期的《柳叶刀》杂志上,科学家们报告说,每周光顾快餐店两次或两次以上的受试者比每周光顾不到一次的受试者体重增加了 10 磅,胰岛素抵抗增加了两倍。“虽然关于快餐对肥胖症的影响已经有很多讨论,但这似乎是第一个科学、全面的长期研究,表明快餐消费、肥胖症和 2 型糖尿病风险之间存在密切联系,”研究合著者、明尼苏达大学的马克·佩雷拉 (Mark Pereira) 评论道。

佩雷拉和波士顿儿童医院的大卫·路德维希 (David Ludwig) 同事跟踪了 3,031 名年龄在 18 岁至 30 岁的非裔美国人和白人年轻人,研究开始时为期 15 年,监测他们的快餐习惯、体重和胰岛素抵抗。考虑到观看电视、身体活动、饮酒、吸烟和其他生活方式因素,该团队确定,快餐摄入量引起的体重增加和胰岛素抵抗似乎在很大程度上独立于这些因素。

Kate Wong is an award-winning science writer and senior editor at 大众科学 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
