The purpose of food portion-size training is to help you estimate food portion sizes that you will ask to remember during the dietary recalls you will participate later in the study.  One of our dieticians will teach you how to identify how much you are eating using tips and some handouts.  For example, the dietician will help you figure out what a ½ cup of pasta, like in this picture, looks like.  This training will take about 10 minutes.  I’ll talk about the recalls shortly.
