Effect of coffee ingestion on catecholamine release.

Abstract Urinary catecholamine excretion was studied in 18 young male subjects during a control period and following the ingestion of coffee. This study showed that ingestion of coffee in moderate amounts resulted in a significant increase in the urinary catecholamine excretion. The possible effects of such long-term catecholamine stimulation is discussed, especially with reference to their effect on blood lipids.
