Whenever Gu Yiwen goes to the university canteen or a restaurant, the 23-year-old Nanjing University translation student brings two tools with her – a pen and a memo. She writes down the ingredients of all the food she’s consumed in order to later log them in iCalorie, a smart phone application that keeps track of the calories she has absorbed. Science and technology have helped her maintain a healthy diet.
