Now we can confidently say that abstinent consumption of coffee is not only safe, but also beneficial for the heart. This conclusion was made by Australian scientists based on the results of a study involving more than 228,000 people.
Patients with a history of myocardial infarction daily consumed 500 milligrams of caffeine. As a result, they normalized their heart rate. The reason is that coffee stimulates the nervous system, blocking the action of the substance, which causes one of the types of arrhythmia – atrial fibrillation.
