Impact of Coffee Consumption on Fructose-Related Metabolic Alterations: Potential Mechanisms and Implications for Metabolic Diseases

Coffee is one of the most widely consumed beverages worldwide. Coffee and its bioactive compounds, including caffeine, chlorogenic acid, and caffeic acid, have attracted increasing attention because of their potential health benefits. Evidence from pediatric and adult populations supports a positive association between fructose intake from sugar-sweetened beverages and the increasing prevalence of obesity and other non-communicable diseases. In this context, coffee consumption may represent a potential protective dietary factor against high fructose intake-induced metabolic alterations, including obesity, type 2 diabetes, liver disease, cardiovascular disease, and alterations in gut microbiota composition. Therefore, this review summarizes current evidence on the potential role of coffee consumption and coffee-derived bioactive compounds in modulating fructose-induced metabolic alterations and discusses the mechanisms involved. However, current evidence from human studies remains limited, and the clinical relevance of the beneficial effects observed in experimental models requires confirmation through well-designed clinical trials.
