Medical College Students' Responds to Menu Labeling

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate whether exposure to nutrition information with or without nutrition education would influence college students' dietary choices and improved the previous photographs-based dietary assessment tools.

Detailed Description
-----------------
The investigators improved the previous photographs-based dietary assessment tools and utilized the improved approach to evaluate participants' calorie and nutrients intake. A pre-post non-controlled study design was implemented in the medical college and was divided into three stages: just recording the dietary selection in the three meals daily, recording the dietary selection with the provision of menu labeling accompanying with or without nutrition education. The investigators adopted photographs-based dietary assessment tools and a mobile phone application 'WeChat' was utilized as the photographs and nutrition knowledge transfer platform. Two professional researchers respectively read the received photographs and calculated participants' calorie and nutrients intake.
