Coffee may protect against stroke and diabetes - optimal dose named

An analysis of studies shows that moderate coffee consumption (up to 400 mg of caffeine per day) is safe for most healthy adults and may reduce the risk of stroke and type 2 diabetes. However, additions like sugar and cream negate the benefits, and individual reactions to caffeine vary. Filtered coffee is recommended for those with high cholesterol, and caution is advised for pregnant women and people with arrhythmia.

The article, based on a publication by Egészség Kalauz, examines the health effects of coffee. According to cardiologists, the safe dose of caffeine for most adults is up to 400 milligrams per day, equivalent to several cups of black coffee. Adding sugar, syrups, or fatty cream increases calorie content and negates the drink's beneficial properties. Studies do not confirm that coffee necessarily causes hypertension, although caffeine can temporarily raise blood pressure. A statistical association has also been found between regular coffee consumption and a reduced risk of type 2 diabetes, but coffee cannot independently prevent the disease. Reactions to caffeine are individual due to genetic variations in liver enzymes. For those with high cholesterol, coffee brewed with a paper filter is recommended, as it traps oils that raise cholesterol. Pregnant women and people with heart rhythm disorders should exercise caution, as should those taking medications. Overall, moderate coffee consumption can be part of a balanced diet.
