One of the popular beverages consumed daily is coffee. The major active ingredient in coffee is caffeine, which is also found in cola fruit, cocoa seeds and tea.

Caffeine is a mild stimulant and may increase alertness and concentration by acting on our central nervous system. Excess caffeine may cause insomnia, palpitations, tremors, irritability and anxiety.
A cup of coffee and cola contains approximately 60 mg and 40 mg of caffeine respectively. Tea contains more caffeine than coffee, but as less tea is used to make a serving of this beverage, overall consumption of caffeine is less.

The best way of hydrating ourselves is to drink about 8 glasses of water daily.

Any more suggestions?
