Method: A nutritional study was undertaken of thirty-five soccer referees (aged between 18 and 50) refereeing at
different levels, from the Spanish national third division down to the provincial second division. Through the use of
a 3-day food diary and 24-hour recall, this study analyzed the intake and distribution of macro- and micro-nutrients
and of dietary fiber consumed on different types of day (normal, training, and match days).
