Data on coffee consumption were collected for 1074 adults attending for health checks in the OXCHECK study, to assess associations with serum lipids and blood pressure. Of the sample, 70.5% drank coffee, largely instant. Coffee had no significant effects on total or high-density lipoprotein (HDL) cholesterol or blood pressure, and was negatively correlated with serum triglycerides. The type of coffee drunk in the UK does not adversely effect these cardiovascular risk factors.
