Dietary Habits of Elite Soccer Players: Variations According to Competitive Level, Playing Position and Sex.

Soccer is a sport practiced worldwide by both men and women, where nutrition plays a fundamental role in the performance of soccer players, providing them with the nutrients necessary for energy, muscle recovery and injury prevention. The aim of this study is to describe the dietary habits in elite soccer players and their association with their competitive level, playing position and sex. A descriptive and non-experimental comparative study was conducted during the 2021-2022 competitive season. A total of 105 players belonging to a Spanish elite soccer team completed a food frequency questionnaire (FCFQ). It was observed that male players presented a higher consumption of carbohydrate-rich foods ( p < 0.05), fermented foods ( p = 0.014), frozen foods ( p = 0.049) and red meat ( p = 0.012) compared to female players, with the exception of lean meats, which were higher in females ( p = 0.012). Furthermore, the U16-15 categories stand out for consuming carbohydrate-rich foods such as pasta ( p = 0.000), bread ( p = 0.004) and sweets ( p = 0.046), as well as frozen foods ( p = 0.002). Finally, alcohol consumption is higher in the senior categories (42.9%), where men are more likely to drink mixed drinks (6.2%), and beer and wine by women (10.7%). Practically no differences were found between the playing positions. In conclusion, differences were found in FCFQ according to competitive level and sex.
