Measurements of eating problems using data communications of cell phones and an attempt to intervene in eating habits

在过去的几十年里，快餐和工业加工食品在日本广泛传播。随着这种扩散，日本消费者对食品的看法和态度也发生了变化。为了研究这些变化，我们建立了一个系统，使用手机的数据通信功能记录日常生活中的饮食习惯。通过对大学生饮食习惯的观察，了解大学生的心理特点，并尝试进行干预，以改变大学生的饮食习惯。

In the past few decades, there has been a wide-reaching diffusion of fast food as well as industrially processed foods in Japan. In line with this diffusion, perceptions and attitudes about food among Japanese consumers have also changed. In order to examine these changes, we set up a system to record eating habits in everyday life using functions of data communications of cell-phones. By observing eating habits of university students using this system, we examined their psychological characteristics and tried to make intervention in order to modify their eating habits.
