Long-term and large-scale drinking may also increase the risk of cardiovascular disease. While enjoying the charm of black coffee, you should drink it in moderation to avoid the challenges brought by excessive intake.

In busy modern life, black coffee has become a must-have drink for many people. It is loved by consumers for its unique charm, such as improving attention and promoting metabolism.
