Coffee is one of the most extensively researched components in the diet with new studies regularly being added to the large body of scientific research, which overall suggests that moderate coffee consumption is not associated with adverse effects on cardiovascular health. To mark World Heart Day on 29th September the Coffee & Health website was updated with a special feature highlighting studies published in 2013. These studies examine the relationship between coffee, cardiovascular health and key risk factors.

We are always adding interesting new content to the Coffee & Health website, and recent additions this quarter include the ‘Coffee and your health’ and ‘Coffee composition and nutritional profile’ topics.

The new ‘Coffee and your health’ topic has been developed to serve as an overview of the latest scientific evidence on the relationship between coffee drinking and various aspects of health.

‘Coffee composition and nutritional profile’ is a new resource for healthcare and other professionals which details key facts about the composition of coffee, derived from the natural components of the coffee bean, and the nutritional profile of a 100ml cup of medium strength, black caffeinated coffee.

We have also developed a brand new section called “All about Caffeine”, which includes an expert vodcast on the subject and up-to-date information and studies on caffeine.

Have you caught up recently with the latest research on the Coffee & Health website? We regularly publish abstracts of the latest research papers on coffee and health, so you can see at a glance what's new in this area. You can now view these abstracts by topic, as well as by date.

Recent studies published include:

New review paper suggests coffee consumption is associated with a reduced risk of mortality
Results from this study support a significant inverse (i.e. favourable) association between coffee consumption and risk of death. Overall, the risk of death decreased by 14% for high (5–6 cups per day) versus no or low (less than 1 cup per day) coffee consumption. Even consumption of one or two cups of coffee daily was associated with a lower risk of death (reduced by 8 %).

Coffee and caffeine intake and incidence of type-2 diabetes
Research suggests that coffee and caffeine consumption may significantly reduce the risk of type 2 diabetes mellitus

Review of research on caffeine use disorder
A recent review of research on ‘caffeine use disorder’ has highlighted that some caffeine users can become dependent and may have difficulty in reducing their consumption, but more research is needed to determine the reliability, validity and prevalence of ‘caffeine use disorder’.

Coffee consumption unlikely to adversely affect cardiovascular health
A series of randomised trials has found that unfiltered coffee increased circulating LDL cholesterol and triglycerides concentrations, but filtered coffee had no substantial effect on blood lipids.

Increased mortality rate associated with coffee consumption
In multivariate analyses, coffee intake was positively associated with all-cause mortality in men. Men who drank more than 28 cups of coffee per week had 21% increased all-cause mortality.
