Objective: Chocolate, renowned for its abundance of bioactive flavonoid compounds, is recognized as a delectable food option with purported benefits for both athletes and general population. Nevertheless, there is no consolidated overview detailing the effects of chocolate consumption specifically among football players. This review aims to elucidate the diverse impacts of chocolate consumption on football players. Methods: A systematic search adhering to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines studies that met the inclusion criteria was conducted in the databases of Google Scholar, PubMed (MEDLINE), Scopus, Embase, and Web of Science to April 01, 2024. Forthy-eight articles were retrieved, of which nine studies met the inclusion criteria. Results: The findings of these studies indicate that chocolate consumption is associated with a decrease in diastolic blood pressure, mean blood pressure, plasma cholesterol, Low-density lipoprotein cholesterol, malondialdehyde, urate, platelet count, mean platelet volume, and platelet distribution width. It was found to reduce intestinal permeability as well as muscle damage biomarkers such as creatine kinase, lactate dehydrogenase. Furthermore, chocolate consumption was associated with an increase in vitamin E/cholesterol ratio, antioxidant power, mean daily exercise time, heart rate, time to fatigue, physical performance, and improvement in redox status. Conclusion: Despite the limited number of studies in this area, small sample sizes, and the presence of limitations in each study, chocolate consumption has demonstrated the potential to enhance athletic performance and recovery in football players. However, further research is essential to fully understand the scope of these effects.
