Energy drink or health hazard?

Last year the World Health Organization branded energy drinks as a “danger to public health”. Caffeine is the most common stimulant in these drinks, but some brands contain other stimulants, such as guarana and ginseng.

The amount of caffeine in an energy drink can range from 80 mg to over 500 mg: a cup of coffee contains around 100 mg. Like other fizzy drinks, energy drinks are high in sugar. A 250 ml can of Red Bull, for example, contains around 27.5g.

Caffeine enters the bloodstream within 10 minutes of consuming the drink and peaks over the next 15-45 minutes, triggering a rise in heart rate and blood pressure. Within an hour, the effects of the caffeine will begin to subside and a sugar crash may occur. Energy levels will begin to feel low and tiredness will set in.

Individuals who consume energy drinks regularly may experience caffeine withdrawal in the 12-24 hours after consumption, which includes symptoms such as headache, irritability and constipation. Think before you drink….
