New dietary analysis tool for athletes

A new user-friendly alternative to previous dietary recall methods.


A new website application for athletes called Dietary Analysis Tool for Athletes (D.A.T.A.) has been validated as accurately recording dietary intake based on the 24-hour recall method. "This tool offers sports dieticians and health professionals a new, quick alternative to analyse athletes' dietary intake," said Lindsay Baker, PhD, Principal Scientist, Gatorade Sports Science Institute.

To confirm the accuracy of the tool, Baker and colleagues compared D.A.T.A. with the USDA 5-step multiple-pass method.

How the study was done

A total of 56 athletes ages 14-20 participated in the study. Statistical analysis showed the methods of recall were comparable in estimating 24-hour intake of energy, carbohydrate, protein, total fat, water and several micronutrients.

According to Baker, this digital tool, with an integrated database, generates a report immediately after the recall, which helps sports health professionals provide quick feedback for the athlete. The D.A.T.A. tool and additional sports nutrition resources can be found at

For the database details, nutrient values are obtained from the USDA database as well as restaurant websites and sports nutrition product labels. While the study focused on teen athletes, Baker believes D.A.T.A. could help dieticians and sports health professionals accurately analyse the fluid and food intake of athletes of all ages.

This study was funded by the Gatorade Sports Science Institute.
