Coffee is a beverage that is very popular all over the world. Its pro-health effect has been demonstrated in many publications. This drink can counteract the effects of oxidative stress thanks to its antioxidant properties. The aim of this study was to collect data on the content of microelements with antioxidant activity (manganese, zinc, copper, iron) in coffee infusions, taking into account various factors. The study considered publications from the years 2000-2020 found in Google Scholar and PubMed databases. It was noted that coffee can provide up to 13.7% of manganese requirements per serving, up to 4.0% and 3.1% of zinc requirements for women and men, up to 2.7% and 2.1% of copper requirements for women and men, and up to 0.4% and 0.6% of iron requirements for women and men. Coffee infusions can also be a source of fluoride (up to 2.5%), chromium (up to 0.4% of daily intake for women and 0.2% for men), and cobalt (up to 0.1%). There are no data in the literature regarding the content of selenium in coffee infusions. The origin of coffee beans and the type of water used (especially regarding fluoride) may have an impact on the content of minerals in infusions. The brewing method does not seem to play an important role. As it is a very popular beverage, coffee can additionally enrich the diet with such micronutrients as manganese, zinc, and copper. This seems beneficial due to their antioxidant properties, however the bioavailability of these elements of coffee should be taken into account. It seems necessary to carry out more research in this area.
咖啡是一种在全世界都非常受欢迎的饮品。其对健康有益的作用已在许多出版物中得到证实。由于具有抗氧化特性，这种饮品可以抵消氧化应激的影响。本研究的目的是考虑各种因素，收集关于咖啡冲泡液中具有抗氧化活性的微量元素（锰、锌、铜、铁）含量的数据。该研究参考了在谷歌学术和PubMed数据库中找到的2000年至2020年期间的出版物。研究发现，每份咖啡最多可提供人体所需锰含量的13.7%，女性和男性所需锌含量的4.0%和3.1%，女性和男性所需铜含量的2.7%和2.1%，以及女性和男性所需铁含量的0.4%和0.6%。咖啡冲泡液还可能是氟化物（高达2.5%）、铬（女性每日摄入量高达0.4%，男性为0.2%）和钴（高达0.1%）的来源。文献中没有关于咖啡冲泡液中硒含量的数据。咖啡豆的产地和所用水的类型（特别是关于氟化物）可能会对冲泡液中的矿物质含量产生影响。冲泡方法似乎并不起重要作用。由于咖啡是一种非常受欢迎的饮品，它可以额外为饮食补充锰、锌和铜等微量营养素。鉴于它们的抗氧化特性，这似乎是有益的，然而应该考虑这些咖啡中的元素的生物利用度。在这一领域似乎有必要开展更多的研究。
