Caffeine complements the other flavors in Coke, providing a more complex and satisfying taste profile. Without caffeine, the drink might taste overly sweet.

4. What Are The Effects Of Caffeine On The Body?
Caffeine has various physiological effects on the body. Understanding these effects can help you make informed decisions about your caffeine consumption.

According to a study by the American Heart Association, excessive caffeine intake can lead to heart palpitations and increased blood pressure levels.

Caffeine can interfere with sleep patterns, making it harder to fall asleep and reducing the quality of sleep. It is advisable to avoid consuming caffeinated drinks close to bedtime to minimize these effects.

Health experts generally recommend limiting caffeine intake to 400 mg per day for most adults. This amount is considered safe and unlikely to cause adverse effects.
