While black coffee offers many health benefits, excessive consumption can cause irritation. It is important not to drink black coffee on an empty stomach, as it can increase stomach acid and lead to acidity. Sensitive individuals may experience anxiety, tremors, or restlessness if consumed without food.
To maximize the benefits of black coffee, it is recommended to limit consumption to no more than two cups a day. By following these guidelines, you can enjoy its energy-boosting, mood-lifting, and metabolism-enhancing effects safely.
