16 oz of coffee a day reduces risk of heart failure but > 40 oz increases risk - new study from journal Circulation


A good cup of coffee can get you out of bed in the morning. But for
heart patients coffee's often on the list of things to avoid. The
American Heart Association advises that it might increase the risk of
heart failure.

But a new report suggests that moderate coffee drinking could actually
lower the odds of heart failure. The findings are in the journal
Circulation. [Elizabeth Mostofsky et al, Habitual Coffee Consumption and
Risk of Heart Failure: A Dose-Response Meta-Analysis, link to come]

Researchers poured through five studies that followed more than 140,000
European adults, and included information about coffee intake. People
who drank about 16 ounces of coffee a day-a grande in
Starbucks-speak-had about an 11 percent reduction of the risk of heart
failure. People who drink coffee also seem to have less type 2 diabetes,
another risk factor for heart disease.

But that doesn't mean it's time to start ordering the venti. In the
studies, people who consumed more than 40 ounces a day were at an
increased risk for heart failure. More research should filter out the
best info, which will percolate down to the public.
