NEJM Journal Watch: What is the effect of coffee consumption on mortality?

Featured

Moderate consumption of unsweetened or sugar-sweetened coffee was associated with lower mortality in an observational study.

Comment:

“Associations between coffee consumption and mortality surely are confounded by numerous factors. If there is really a causal protective link, it might be related to coffee’s chlorogenic acids, which — in addition to caffeine — have an antioxidant effect and inhibit platelet aggregation, as an editorialist notes. A study limitation is that, on average, only 4 g of sugar were added to sweetened coffee (likely less than many Americans add). Nevertheless, this study reaffirms that even sweetened coffee is likely not harmful and might even be beneficial.”

“Two studies confirm an association between coffee intake and lower risk for death in diverse populations.”

Comment:

“These studies provide support that moderate coffee intake (2–5 cups daily) is safe and associated with reduced risk for death, probably in a dose-dependent fashion. If you’re still debating the health benefits of coffee for your patients, you may want to do it over a cup of joe.”
