Coffee may protect your heart but energy drinks could harm it

Researchers have found that consuming up to 400 milligrams of caffeine daily, equivalent to three to five cups of regular black coffee, is generally safe for most adults and may even lower the risk of heart disease, stroke, and other conditions. This daily caffeine habit may be linked to various health benefits, including a reduced risk of heart failure and Type 2 diabetes. However, the source of caffeine is crucial, as highly concentrated energy drinks and shots can have negative effects on heart health. These energy drinks can cause sharp increases in blood pressure and trigger irregular heart rhythms, posing a potential harm to the heart.
