Adults can safely drink up to three to five mugs of coffee a day. Research shows bigger amounts usually don’t raise heart trouble. Coffee may even improve the heart because of compounds it contains. Energy drinks are different. They combine caffeine and sugar in ways that can harm the heart. Experts agree coffee in normal doses is fine. People with heart problems should ask their doctor first.
