(NBC News) Red wine has been hailed in the past as a heart-healthy drink, but in a new study it failed to show any benefit.
Researchers at Johns Hopkins University School of Medicine followed nearly 800 older adults in Italy for nine years.
They found no link between concentrations of the key red wine antioxidant, called resveratrol, in the participants' bodies and a reduced risk for cancer, heart disease or early death.
Still, outside experts say it's too early to cork your Cabernet.
"There are a lot of studies that have really proven its benefits, so I wouldn't necessarily change their whole outlook on their way of eating just yet," says Cleveland Clinic dietitian Julia Zumpano.
Resveratrol is also found in grapes and dark chocolate, foods that are included in the famously healthy Mediterranean Diet which also includes plenty of fish, vegetables, nuts and seeds.
