400mg+ daily caffeine increases heart attack or stroke risk for healthy individuals, study reveals.

400mg+ daily caffeine consumption (equivalent to 4 cups of coffee or 2 energy drinks) can increase heart attack or stroke risk for healthy individuals, reveals a new study. It suggests that chronic caffeine intake impacts the autonomic nervous system, causing elevated heart rates and blood pressure over time. High blood pressure is associated with heart disease, heart failure, chronic kidney disease, and dementia. The study of 92 healthy participants found that those who consumed the highest amounts of caffeine had significantly elevated heart rates and blood pressure.
