American Heart Association says up to five cups of coffee a day is safe |
| The American Heart Association (AHA) has said that drinking up to five 8-oz cups of coffee a day, or around 400mgs of caffeine, is safe for most adults and may reduce the risk of heart disease, heart failure, stroke, and Type 2 diabetes. The scientific statement, published in Circulation, reviewed dozens of studies and concluded that evidence supporting coffee’s safety and potential cardiovascular benefits has strengthened over time. The AHA said the greatest benefits appear to come from consuming two to four cups of coffee daily, while noting that individual responses to caffeine vary. Researchers also cautioned that adding large amounts of sugar, syrups, or high-fat creamers can offset potential health benefits, and advised consumers to avoid high-caffeine energy drinks, which have been linked to irregular heart rhythms and high blood pressure. |
