Bionutrition
The role of the bionutrition core is to assist investigators in
planning, developing, implementing, and evaluating the nutrition
component of clinical research protocols. The University of Rochester
Medical Center has had a long history of research and interest in the
areas of diabetes and weight management. These and other research
areas such as neurology, AIDS, and autism have necessitated nutrition
control, which have been supported by the nutrition staff of the CRC.
Key Personnel

Diet Assessment Tools
These tools and training materials are used by researchers to ensure the accurate collection of nutrition related data.
This chart is used to help a subject categorize his or her
stool. The different types of stool represented are related to the
length of time the stool has spent in the colon. This tool can be used
to assess bowel movements and is often used in correlation with dietary
intake.

transit time". Scand. J. Gastroenterol. 32(9): 920-4
Three Day Food Record
The 3 Day Food Record is considered to be one of the most
accurate methods of assessing dietary intake of an individual at one
point in time. These training materials provide relevant information
that an individual needs to know in order to accurately fill out a 3 Day
Food Record.
3 Day Food Record Training Presentation
The presentation includes:
- Instructions on the level of detail needed
- Instructions on how to record vitamins and minerals
- Tips to help estimate food amounts

Food Record Instructions
Individuals often do not realize the level of detail that is
required for a food record. This document contrasts a less accurate
food record with a more complete one:

Tools from Nutrition Coordinating Center
Nutrition Data System for Research (NDSR) is a dietary analysis
program created by the Nutrition Coordinating Center (NCC) at the
University of Minnesota. The NCC is supported by the National Heart,
Lung, and Blood Institute (NHLBI) and the National Institutes of Health
(NIH).
