The dual impact of coffee consumption: Health benefits and risks

Abstract

Coffee is one of the most widely consumed beverages worldwide, known for its stimulating effects due to caffeine, as well as a wide range of bioactive compounds like chlorogenic acids, cafestol, and kahweol. While moderate coffee consumption has been associated with numerous health benefits, including protection against chronic diseases such as type 2 diabetes, Parkinson’s disease, and certain cancers, its excessive consumption may also pose risks, such as cardiovascular issues, anxiety, sleep disturbances, and dependence. The dual impact of coffee consumption—its beneficial and detrimental effects—depends on factors such as the quantity consumed, individual susceptibility, and timing of intake. While moderate consumption (2-3 cups per day) has been linked to improved cognitive function, mood regulation, and longevity, excessive coffee intake can lead to adverse health outcomes, including hypertension, arrhythmias, and mineral deficiencies. This paper aims to critically examine the dual nature of coffee consumption, focusing on both its health benefits and risks. Through a review of existing literature, this study explores the mechanisms behind coffee’s effects on health and provides recommendations for optimal consumption patterns. Understanding the balance between the positive and negative impacts of coffee is crucial for promoting informed consumption and maximizing its health benefits while minimizing potential risks.
