Research on coffee consumption has yielded positive results for those who drink coffee in moderation. A study published in the journal Circulation found that drinking up to five 8-ounce cups of coffee per day is safe and has benefits for heart health. Drinking more than this amount may lead to problems, according to the research.

Further details on the study's findings are available from Houston Public Media, for readers in Spring, TX, who want to learn more about the effects of coffee consumption on heart health.
