Abstract Information on dietary composition is vitally important for elite athletes to optimise their performance and recovery, which requires valid tools. The aim of the present study was to investigate the validity of assessing protein intake using three web-based 24-h recalls and questionnaires, by comparing these with three urinary N excretions on the same day. A total of forty-seven Dutch elite top athletes, both disabled and non-disabled, aged between 18 and 35 years, with a BMI of 17·5–31 kg/m2, exercising >12 h/week were recruited. Estimated mean dietary protein intake was 109·6 (SD 33·0) g/d by recalls and questionnaires v. 141·3 (SD 38·2) g/d based on N excretions in urine; the difference was 25·5 (SD 21·3) % between the methods (P
