Coffee is a beloved beverage enjoyed worldwide. In particular, Korea’s coffee consumption is more than twice the global average, making it a staple in daily life. Drinks like americano and iced americano are extremely popular, and coffee is now a common ingredient in countless beverages. Although this love for coffee is remarkable, it does come with concerns. While many people typically drink 1–2 cups per day, some consume 4–5 cups or even more, which can lead to potential side effects. Coffee does offer clear health benefits, but excessive consumption may result in negative effects as well.
Main Components of Coffee
- Caffeine: The most notable component, caffeine stimulates the central nervous system, boosting energy and reducing fatigue.
- Antioxidants: Coffee is rich in antioxidants such as polyphenols, helping reduce oxidative stress and protecting cells.

Recommended Intake
For adults, it is recommended to limit daily caffeine intake to no more than 400mg—roughly equivalent to four cups of coffee. However, this is the maximum recommended amount, and it is better to consume less if possible. Individual sensitivity to caffeine can vary, so these limits should be adjusted as needed.
