The bottom line for caffeine facts
So far, there is not much evidence that moderate use of caffeine is unhealthy. However, as mentioned above, people with certain conditions should limit or avoid it, especially if you seem to be more sensitive to its side effects.
--Caveat for Caffeine Facts: If you habitually use caffeine to override your body's need to sleep, you will pay a price in the long run. Your physical and mental health will suffer if you constantly thwart your body's built-in warning signals.
My advice is that caffeine-containing beverages should be used only in moderation , in the form of coffee or tea, but not as a replacement for water consumption. Soft drinks and energy drinks that are loaded with sugar, artificial sweeteners and other chemicals have no real place in a healthy diet.
I hope these caffeine facts will help you make good choices for your health.
