Can’t live without caffeine, can you? Most adults around the world consume caffeine every day, in coffee, tea, cola, or chocolate. And we continue to hear about new studies – some warning us to stay away from caffeine and others glorifying its benefits.
So what is the truth?
A scientist from the UK reviewed 41 caffeine studies from the last 15 years. Most of the studies found that low to moderate caffeine intake – less than 400 mg per day (the equivalent of no more than eight cups of tea or four cups of ordinary coffee) – improved alertness and mental performance. Studies also found that up to 400 mg of caffeine per day did not cause dehydration, which is thought to be a common side effect of caffeine intake.
But beware of mega-coffee! Find out exactly how much caffeine is in your so-called “cup.” For example, a “tall” Starbucks beverage can range from 75 mg of caffeine (Cappuccino) to 150 mg (Caffe Americano) to 260 mg (regular coffee).[Ed.
