About Dietary Research: Methodologic Research
Our goals in this area are to increase the precision of dietary intake
estimates by improving self-report of dietary intake and the analytic procedures
for processing reported information. This work is designed to facilitate our
monitoring and nutritional epidemiology efforts and to advance our understanding
of the relationship of diet to cancer outcomes.
Major initiatives for improving self-reported dietary information include
developing and testing a new automated, self-administered 24-hour dietary recall
(ASA24™) to assess total diet. One
way we are improving analytic procedures is by developing ways to improve the
estimates of usual intake as reported in food consumption surveys that employ
24-hour recalls. We also develop and test short screeners to assess particular
nutrients or food groups.
