Coffee consumption vs. cancer risk – a systematic review of scientific data
Coffee and its impact on health continue to be the topic of much heated debate. Until recently, coffee consumption has been believed to be associated with adverse effects, mainly cardiovascular problems. However, the vast majority of contemporary sources not only emphasize a lack of detrimental effect, but also suggest a beneficial effect of coffee intake. According to the current state of knowledge, coffee consumption is not associated with the majority of cancers although the results of studies on bladder and lung cancer remain conflicting. In case of colorectal, liver and breast cancers, coffee drinking may even have a protective effect. Coffee contains numerous compounds, potentially beneficial as well as harmful. The former include polyphenols which inhibit harmful oxidation processes in the body, while the latter include acrylamide, whose high intake in daily diet may have carcinogenic action. The impact of coffee on the human body is associated also with other factors, e.g. the rate of metabolism and other individual features.
