節目的transcript在這裏https://www.npr.org/transcripts/1218737982, 下麵摘選了相關的一段對話。SEGARRA是節目主持人，GODOY是NPR science and health correspondent, DAMMAN是被采訪的gastroenterologist and microbiome researcher at the University of Washington。這個采訪很簡單直白，也許有些過於簡單化。主要就是說飯後走路的一些好處，除了當笑話說的幫助消化排氣（放屁），對調節血糖，減輕胰髒負擔也是有用的。肌肉收縮的時候會像海綿一樣把血液中的葡萄糖吸收到肌肉裏，從而做到胰島素做到的事，因此胰髒就不需要那麽努力的分泌那麽多胰島素。但是timing很重要，一定要在飯後３０分鍾內開始活動。旺旺說的２小時以內可能還是久了一點。當然了，具體的實驗啥的我是沒看到的，我也不是專業人士，就是覺得這個采訪用簡單易懂的語言解釋了一些東西，給大家做個參考。
DAMMAN: When we move our muscles, they become sponges for the blood glucose that our gut is absorbing into the bloodstream. And so it basically just pulls all that glucose out of the blood and into the muscles.
GODOY: And so what happens is we end up using that sugar right away to fuel our walk.
SEGARRA: But don't most people have a built-in way of doing this? I thought that was what insulin was for - to clear blood sugar.
GODOY: Yeah, that is exactly what insulin does. It's a hormone that clears glucose out of the blood and into nearby cells. But the cool thing is that, when you contract your muscles through walking, they also do this. They clear that blood sugar even without any insulin present. What that means is that our bodies don't have to produce as much insulin, and that's good because then your pancreas doesn't have to work as hard to make insulin. And over time, that can lower your risk of prediabetes and diabetes.
