PHILADELPHIA (CBS) — You begin to wonder just how many studies can be done on coffee, but the more we do the more positive results we’re starting to see.

A new report in the journal “Heart”, found that drinking coffee could reduce the risk of heart attack.

The study observed those who didn’t drink coffee and those who drank three to five cups per day.

The report found those who drank coffee had a lower risk of having calcium deposits in their coronoary arteries, which is one of the best predictors of heart disease.

Research was done at Johns Hopkins and the study was conducted on young, healthy adults in Korea.
