We measured the agreement of our novel, digital dietary analysis tool for athletes (DATA) with the 24‐h dietary recall interview using the USDA 5‐step multiple‐pass method (INTERVIEW). Fifty‐six athletes (14–20 yr; 42 male, 16 female) completed DATA and INTERVIEW in a randomized counter‐balanced order (back‐to‐back on the same day). Intraclass correlations (ICC) and paired comparisons (expressed as % difference between methods) with 95% confidence intervals were used to determine statistical agreement between DATA and INTERVIEW. The ICC's between DATA and INTERVIEW were significant for energy (0.86, 0.76–0.92), carbohydrate (0.89, 0.81–0.94), total fat (0.75, 0.58–0.86), protein (0.89, 0.81–0.93), water (0.85, 0.75–0.91), sodium (0.85, 0.75–0.91), iron (0.83, 0.72–0.90), and calcium (0.91, 0.85–0.95). In addition, the differences between methods were not significant for energy (−1.1%, −9.1 to 7.7%), carbohydrate (0.2%, −7.1 to 8.0%), total fat (−6.1%, −17.8 to 7.4%), protein (−2.7%, −11.3 to 6.7%), water (−1.2%, −9.1% to 7.3%), sodium (−3.2%, −13.3 to 8.1%), iron (−8.4%, −18.3 to 2.7), and calcium (−0.4%, −10.0 to 10.3%). The DATA digital program is a valid 24‐h dietary analysis tool and can be used by sports health professionals looking for a quick, user‐friendly, athlete‐specific alternative to conventional 24‐h dietary recall methods.
