請注意,快餐愛好者們。如果新年伊始還不足以讓您改變飲食習慣,那麼新的研究結果可能會讓您改變。一項長期研究明確地將快餐消費與肥胖症和 2 型糖尿病聯絡起來。

在最新一期的《柳葉刀》雜誌上,科學家們報告說,每週光顧快餐店兩次或兩次以上的受試者比每週光顧不到一次的受試者體重增加了 10 磅,胰島素抵抗增加了兩倍。“雖然關於快餐對肥胖症的影響已經有很多討論,但這似乎是第一個科學、全面的長期研究,表明快餐消費、肥胖症和 2 型糖尿病風險之間存在密切聯絡,”研究合著者、明尼蘇達大學的馬克·佩雷拉 (Mark Pereira) 評論道。

佩雷拉和波士頓兒童醫院的大衛·路德維希 (David Ludwig) 同事跟蹤了 3,031 名年齡在 18 歲至 30 歲的非裔美國人和白人年輕人,研究開始時為期 15 年,監測他們的快餐習慣、體重和胰島素抵抗。考慮到觀看電視、身體活動、飲酒、吸菸和其他生活方式因素,該團隊確定,快餐攝入量引起的體重增加和胰島素抵抗似乎在很大程度上獨立於這些因素。

Kate Wong is an award-winning science writer and senior editor at 大眾科學 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.
