Resumo(s)
Coffee includes some potentially bioactive components that can interfere with platelets,
which can influence coagulation, despite generating controversy. The aim of this systematic review is to
verify whether coffee or its components can influence platelet regulators and/or aggregation.
Materials and Methods: The research was conducted on July 29, 2021, in PubMed, Scopus, andWeb of Science,
using the followingmesh-terms: (caffeine)) OR (coffee)) AND (platelets). Eligibility criteria were: studies
carried out in humans, referring to the effects of coffee consumption, or one of its components, on platelets
or their regulators. We exclude in vitro or animal studies, reviews, editorials, and non-English written studies.
From a total of 836 publications, 17 articles were included from which we extracted the relationship between
coffee consumption and changes in blood platelets and performed a subjective assessment of bias.
Results: Ten articles refer to the non-interference of coffee or its components with platelets, nine affirm
results that support the increase in platelet aggregation, and eight articles observe the decrease in platelet
aggregation when coffee is consumed. Some articles presented the lack of data regarding the sample collection
location, age group, or classification as to the type of study, which is limiting.
Conclusions: The heterogeneity of results makes it difficult to correctly interpret the possible interaction of
coffee or its components with platelets or their regulators. For better interpretation, further studies on this
topic should be carried out considering the individualization of coffee components, different platelet regulators,
and the size of the sample used.
