New Delhi: Coffee is among the world's most consumed beverages, but the debate over whether it is healthy continues. Research suggests that coffee is neither entirely good nor bad. Instead, its effects depend on the amount consumed, the time of day, and an individual's health condition.
For most healthy adults, moderate coffee consumption can be part of a balanced lifestyle. However, excessive caffeine intake may lead to unwanted side effects such as poor sleep, anxiety, digestive discomfort and a temporary rise in blood pressure.

Black coffee is naturally low in calories and may provide a slight boost in metabolism and exercise performance. However, experts stress that coffee alone cannot cause weight loss. Adding sugar, whipped cream or flavoured syrups significantly increases calories and reduces any potential benefit.
Current research suggests that coffee can be a healthy beverage when consumed in moderation. The key is understanding your body's response, avoiding excessive intake and limiting caffeine later in the day. While coffee may offer several health benefits, balance remains the most important ingredient.
